Note: After making up the Stator Housing Adapter with a chain tong, there should be no gap between either the Stator Housing Adapter and the Adjusting Ring or the Adjusting Ring and the Offset Housing (check with feeler gauge). If there is a gap, this is because the Offset Housing has been backed off one turn (or more) too many from the Inner Mandrel during step (4). Back off the Stator Housing Adapter two turns, lift the Adjusting Ring and make up the Offset Housing one turn onto the Inner Mandrel (the required number slots are again aligned). Follow steps (5) and (6) again. If there is still a gap, then repeat these steps. Incorrect adjustment of the housing may result in a catastrophic downhole failure or tool joint separation. Contact your local Sperry-Sun Directional Drilling Department if there is any doubt as to whether or not the adjustment has been performed correctly.

It is recommended that only the weight of the motor is used during the measurement of value L2. The SPERRY DRILL motor uses an internal load sharing mechanism resulting in smaller L2 values at increased loads, which are caused by BHA components being attached to the motor. This can lead to incorrect bearing gap values being calculated since gap size = L1 — L2. To permit relative bearing wear assessment, ensure that the load applied to measure value L2 is the same before and after the motor run. If BHA components and/or the kelly are made-up to the motor, only the weight of the motor should be slackedoff on the drive shaft and bearings. It is recommended that thrust bearing gap measurement operations are undertaken after motor flow testing, permitting the maximum L1 value to be measured. Some bearing packs can be configured to cope with loads outside the standard settings in the motor specification listings. Consult your local Sperry-Sun representative for information.

1.9 MOTOR/DRILLSTRING ROTATION DATA Drillstring rotation can be applied during motor drilling to optimize operating parameters such as the penetration rate and hole cleaning. Drillstring rotation and therefore motor rotation increases the cumulative mechanical loading (stress) effects on many motor components above those encountered during motor operations where there is no drillstring rotation.

50

Maximum drillstring rotation rates vary for different motor and application types. The maximum acceptable drillstring rotation rate is related to the stress levels in, and fatigue life criteria of the motor components. The stress levels depend upon many factors, these include motor geometry, motor bend angle setting, BHA/motor stabilization, BHA stiffness, actual weight applied to the motor, actual hole size, actual hole curvature, orientation of the motor with respect to the hole curvature and hole inclination. Exact values regarding maximum motor rotation rates, which incorporate factors of safety, can not be specified due to the variance in cumulative motor loadings which are experienced in individual motor applications. Excessive drillstring rotation rates can promote accelerated wear of rotors and stators, can cause belling of threaded connections and can cause cyclic fatigue of motor components in straight and bent motors. Aggressive doglegs, inadequate BHA stabilization, excessively overgauge holes and inefficient hole cleaning can contribute to the cyclic fatigue of straight and bent motors at relatively low drillstring rotation rates. For related information see 1.10, 4.13, 4.14 and B.7. GUIDELINES: Drillstring rotation rates must be considered with respect to individual application conditions. As a general rule the drillstring rotation rate should be kept as low as possible. In most drilling applications drillstring rotation of 40 to 80 RPM is sufficient. Given known favorable conditions, 51

A range of modified SPERRY DRILL motors have been developed which allow drillstring rotation of up to 200 RPM. Further details are available from Sperry-Sun.

1.10 DOGLEG PREDICTION & DRILLSTRING ROTATION RATE VS. BENT HOUSING ANGLE The charts that follow provide, for common motor/hole size combinations: 1. a guide to the dogleg that is expected from a given bend setting, and

HOW TO USE THE CHARTS: 1. Determine the dogleg required to drill the section. 2. Determine the bend setting to give that dogleg. 3. If the dogleg is below the limit, AND the bend setting is below the limit (for the motor/hole size combination), drill ahead. Note: The maximum dogleg is not necessarily the dogleg computed from surveys. “Steering one, rotating two” will concentrate the dogleg in the first single. For additional information see 4.13, 4.14, and B.7. The charts presented relate to motors with standard (Std.) bearing assemblies.

The values and limits are not absolute and will vary with application. Slow rotation outside the limits to reset toolface is acceptable. If an application would benefit from exceeding the limits over longer periods, check first with your Sperry-Sun district office. SPERRY DRILL motors can be configured to allow string rotation speeds up to 200 rpm, and to allow limited rotation in bigger doglegs than given here. The graphs apply to drilling: back reaming at full drilling flow rates and rotary speeds is not advised. A minimum reduction of 30% of flow rate and 50% of drillstring RPM is recommended when back reaming.

2.1 INTRODUCTION TO PERFORMANCE GRAPHS

SPERRY DRILL MOTOR PERFORMANCE GRAPHS

Within the specified motor operating ranges Operating “Differential” Pressure is directly related to the Output Torque, the Input Flow Rate is directly related to the Output Speed.

GENERAL The data contained in SPERRY DRILL motor performance graphs is a representation of the input and output characteristics of the various motor models, as achieved through repeated bench testing.

The Operating “Differential” Pressures in the graphs represent the actual differential pressures which produce power output from the motors. The Operating “Differential” Pressures in the graphs do not include the pressures required to run the motors at no load. When considering drilling motor output characteristics, achievable “Maximum Operating Load” values should not be confused with higher “Stall” values, where there is no rotation of the drill bit. To minimize the number of graphs required for each model type, one graph is used which combines a number of input/output parameters. In addition to the information contained in this chapter, referencing the following sections is recommended: 3.2 Motor Operating “Differential” Pressure 3.3 Motor Operations Optimization 3.7 Motor Stall 4.6 Rotor Jet Nozzling 4.13.2 & 1.9 Rotation of Drillstring/Motor 4.21 & 1.7 Motor Elastomers, Operating Temperature and Pressure Data

64

Continuous, reliable motor operation at the stated Maximum Operating Load values is possible given optimum drilling conditions. These Maximum Operating Load values should not be confused with higher Stall Torque values where no rotation of the drill bit, and therefore no drilling, occurs. To minimize the number of graphs required for each model type, one graph is used which shows the combined relationship between a number of input/output parameters. Fig 2.1 (1) shows the portion of the performance graph which represents the Operating Differential Pressure versus Output RPM.

High downhole temperatures affect the fit between the rotor and the elastomeric (rubber) stator, this results in increased loading of the elastomer. To minimize the loads on the stator elastomer while operating at high temperatures, the maximum pressure differential which can be applied across the motor is reduced. This moves the “Maximum Operating Load” line to the left on the graph (See 4.21 , 1.7, & B.4).

Given optimum conditions, the Transition Zone is not a consideration and the Nominal Operating Zone ( A ) extends to the specified Maximum Operating Load.

MAXIMUM O P E R AT I N G L OA D

When downhole parameters act adversely they can produce an operating zone, near the motor maximum operating load, where there is a tendency for accelerated wear of motor components. In this zone, there also is a tendency for the onset of the stall condition. Operations in this zone can sometimes be characterized by there being difficulty in maintaining constant motor loading parameters.

ZONE C - “STALL ZONE” This zone represents the occurrence of motor stall. When motor stall occurs the loading from the drill bit exceeds the maximum torque and power which can be produced by the motor, given the specific operating parameters being applied at that time. The output torque rises rapidly and remains at a maximum value while the output RPM rapidly reduces and remains at zero. The occurrence of motor stall stops rotation of the drill bit and the power unit rotor becomes locked in the stator. During motor stall the operating differential pressure across the motor, and the resulting stall torque (sometimes referred to as “Maximum Torque”, where there is no rotation of the bit), can rise to approximately 70% above the specified Maximum Operating Torque.

READING THE MOTOR PERFORMANCE GRAPHS There are various ways to read the graphs: TORQUE VERSUS OPERATING DIFFERENTIAL PRESSURE The torque of a motor varies with operating differential pressure. As the operating differential pressure value increases, the torque increases. To obtain the torque for a given Differential Pressure: 1. Locate the differential pressure value on the Operating “Differential” Pressure axis (bottom horizontal axis) of the graph. 2. Draw a vertical line from the differential pressure value to cut the Torque line. From that point draw a horizontal line to the right hand side until it cuts the vertical “Torque” axis. The Torque for the specific differential pressure can be read off the Torque axis at this point. OUTPUT RPM FOR SPECIFIC FLOW RATES AND OPERATING DIFFERENTIAL PRESSURES The output RPM and flow rate of positive displacement motors are directly related. Each performance graph shows a number of curves which relate to output RPM.

70

This results in RPM curves which drop off towards the Maximum Operating Load line. Beyond the Maximum Operating Load line, the RPM drops off abruptly to zero with the onset of stall. To obtain the RPM for an Operating “Differential” Pressure value at a specific operating Flow Rate for a specific differential pressure value: 1. Locate the differential pressure value on the Operating “Differential” Pressure axis (bottom horizontal axis) of the graph. 2. Draw a vertical line from the Differential Pressure value to cut the RPM curve for the flow rate in question. From there draw a horizontal line to the left hand side until it cuts the vertical “RPM” axis. The RPM value can be read off at this point. When the RPM curve for a specific flow rate is not included in the graph the position and shape of the RPM curve for that flow rate can be estimated relative to the sample curves given on the graph, an estimated curve can be hand drawn onto the graph. The above detailed steps can then be undertaken with respect to the estimated curve. HORSEPOWER FOR SPECIFIC FLOW RATES AND OPERATING DIFFERENTIAL PRESSURES

The curves are given for sample flow rates across the motor operating flow range. Similar curves apply for other flow rates.

Motor Horsepower is a function of the output Torque and Speed at a specific operating differential pressure and flow rate.

As differential pressure increases fluid leakage between the rotor and stator increases. The fluid leakage leaves less fluid available to rotate the rotor.

Horsepower curves are given for sample flow rates across the operating flow range. Similar curves apply for other flow rates. 71

To obtain the Horsepower for an Operating “Differential” Pressure value at a specific operating Flow Rate:

No Load pressure references should be assessed by testing at surface before the BHA is made up (See 4.3).

1. Locate the differential pressure value on the Operating “Differential” Pressure axis (bottom horizontal axis) of the graph.

To provide power to the bit with the motor “On Bottom” the pressure must be increased above the No Load pressure. This additional pressure is the Operating “Differential” Pressure; it is the pressure “differential” required to produce power from the motor.

2. Draw a vertical line from the differential pressure value to cut the “Horsepower” curve for the operating flow rate. From that point draw a horizontal line to the right hand side to cut the “Horsepower” axis. The output Horsepower value can be read at this point. When the Horsepower curve for a specific flow rate is not included in the graph the position and shape of a Horsepower curve for that flow rate can be estimated relative to the sample Horsepower curves provided, an estimated curve can be hand drawn onto the graph. The above detailed steps can then be undertaken with respect to the estimated Horsepower curve.

2.1.2 MOTOR NO LOAD (OFF-BOTTOM) PRESSURE LOSSES For a motor to run the friction between mating parts of the motor must be overcome. This requires that a small pressure is applied across the rotor and stator, this is referred to as the “No-Load” pressure. The No Load pressure varies for different motor model types and for individual motors due to various parameters including: tolerances between mating motor components, differing mud properties and varying downhole temperatures at differing geographical locations. 72

For additional motor “No Load” pressure information contact your Sperry-Sun representative. Note: When considered on their own, motor No Load pressure values, the draining of drilling fluid from the bit/driveshaft and the amount of resistance to the manual rotation of motor driveshafts, are not reliable guides to motor condition and performance downhole. SPERRY DRILL motors are designed to operate downhole at higher temperatures than at surface. The motors are configured with mating part fits which provide allowance for thermal expansion of components such as the rubber stator. At surface temperature, a motor s No Load pressure, its resistance to manual driveshaft rotation and its rotor/stator fluid sealing capacity are less than when the motor is at downhole temperature. Motors are heated externally by the formation and internally by the action of the rotor running in the stator.

OVERVIEW For any size of SPERRY DRILL motor there are a number of configuration options available. Motors can be supplied with or without dump subs and with rig adjustable or fixed bent housings. Some models can be configured with bearing assemblies which permit drilling operations with high drillstring rotation rates and high bit pressure drops. Variable size rotor jet nozzles, rig adjustable sleeve stabilizers and variable stator elastomer types further increase the motor configuration options available. Some SPERRY DRILL motors can be configured to provide measurement of bit inclination by adding the ABI sensor. Sperry-Sun AGS stabilizer technology has been incorporated into SPERRY DRILL motors to produce GEMINI adjustable gauge motors. Various downhole operating parameters can be monitored electronically through the use of instrumented (IMM) SPERRY DRILL motors. Of primary importance to motor configuration selection is the choice of power unit. Power unit selection must be undertaken with respect to required input/output operating characteristics (e.g. required torque and RPM delivery to the bit and required flow rates for bit hydraulics and hole cleaning). In some applications the power unit length and overall motor length may be of importance. SPERRY DRILL motors are primarily classified by their output speed and output power characteristics, which relate to the rotor/stator lobe configuration and power unit length. 184

Power units are designated as being either “Standard” or “Performance”, the performance power units being longer in length and being capable of producing greater output power than standard power units of similar lobe configuration. Some “Performance” power units have lobe configurations which are not available in “Standard” power unit form. For specific applications “Tandem” motors can be configured where two power units are connected together. Specialty motors are available for air/foam, short/intermediate and medium radius drilling. See Appendix ‘A’ for motor applications data. For additional information on specialty motors contact your Sperry-Sun representative. LOW SPEED MOTORS Low speed motors are characterized by them having rotor to stator lobe configurations of 5:6, 6:7, 7:8, 8:9 and 9:10. The use of adjustable bent housings with high torque output and relatively low bit speed makes the low speed motors ideal for use in steerable drilling applications, including horizontal wells and wells in troublesome formations. The output characteristics of the low speed motors can be utilized in various specialist applications such as short and intermediate drilling.

OVERVIEW For any size of SPERRY DRILL motor there are a number of configuration options available. Motors can be supplied with or without dump subs and with rig adjustable or fixed bent housings. Some models can be configured with bearing assemblies which permit drilling operations with high drillstring rotation rates and high bit pressure drops. Variable size rotor jet nozzles, rig adjustable sleeve stabilizers and variable stator elastomer types further increase the motor configuration options available. Some SPERRY DRILL motors can be configured to provide measurement of bit inclination by adding the ABI sensor. Sperry-Sun AGS stabilizer technology has been incorporated into SPERRY DRILL motors to produce GEMINI adjustable gauge motors. Various downhole operating parameters can be monitored electronically through the use of instrumented (IMM) SPERRY DRILL motors. Of primary importance to motor configuration selection is the choice of power unit. Power unit selection must be undertaken with respect to required input/output operating characteristics (e.g. required torque and RPM delivery to the bit and required flow rates for bit hydraulics and hole cleaning). In some applications the power unit length and overall motor length may be of importance. SPERRY DRILL motors are primarily classified by their output speed and output power characteristics, which relate to the rotor/stator lobe configuration and power unit length. 184

The use of adjustable bent housings with high torque output and relatively low bit speed makes the low speed motors ideal for use in steerable drilling applications, including horizontal wells and wells in troublesome formations.

MEDIUM SPEED MOTORS Medium speed motors are characterized by them having rotor to stator lobe configurations of 3:4 and 4:5. The operational characteristics of medium speed motors permit fine tuning of operational parameters and rates 185

of penetration while maximizing bit life and on-bottom time, therefore reducing costs. Applications for medium speed motors include steerable straight hole drilling, extended reach drilling and performance drilling. HIGH SPEED MOTORS High speed motors are characterized by them having rotor to stator lobe configurations of 1:2 and 2:3. The high speed motor operational characteristics make them suitable for use in correction and sidetrack applications where precise directional control permits efficient establishment of the required well inclination and direction. For more details regarding SPERRY DRILL motor configurations see Chapter 4.

3.2 MOTOR OPERATING “DIFFERENTIAL” PRESSURE The motor Operating Differential Pressure is the pressure drop which occurs across the rotor and stator as torque is produced to drive the bit. For maximum reliability Sperry-Sun recommends that all SPERRY DRILL motors are operated with the minimum Differential Pressure required to achieve acceptable ROP and/or directional performance. When a motor is run off bottom at “No Load”, then lowered to the hole bottom, the bit contacts the formation, weight is applied to the bit and the power unit Differential Pressure rises due to the increased torque demand as the bit begins to drill (See 2.1.2). The Differential Pressure produced across the rotor and stator is directly proportional to the torque applied at 186

the bit and the reactive torque which acts upon the stator elastomer (100% differential pressure equates to 100% torque output). Excessive reactive torque and fluctuating reactive torque levels can cause directional control difficulties (see 3.5). If the increasing application of weight to the bit is then halted the motor will normally continue to drill. As formation penetration occurs the weight on bit and differential pressure (and torque) will reduce or “drill off”. If there are consistent circulating fluid properties, flow rate and formation characteristics within the normal SPERRY DRILL motor operating range, an increase or decrease in weight on bit will result in a directly proportional increase or decrease in operating pressure differential and torque. Optimization of ROP can be achieved by varying the application of weight to the bit alone or by varying a combination of weight on bit, flow rate and drillstring rotation rate to accommodate specific formation characteristics. However, formations are rarely homogenous and weight on bit alone is not an indicator of output torque. Rotor and stator power units are designed to operate reliably and efficiently up to a specific steady maximum operating pressure differential. Running a motor with the maximum specified differential pressure results in increased output torque levels and can yield increased ROP rates. However, the higher the operating pressure differential the greater the tendency for rotor and stator wear, the greater the mechanical loading of associated components and the smaller the margin of safety to cope with stall loadings (as 187

excessive torque may be required at the bit due to formation changes). See 2.1.1. Drillstring rotation can be applied to optimize operating parameters such as penetration rate and hole cleaning. Drillstring rotation rates must be considered with respect to the differential pressure (see 4.13).

3.3 MOTOR OPERATIONS OPTIMIZATION Once the motor and bit have been run-in, the optimum drilling rate and directional control can be established by varying the weight on bit and, if possible, the flow rate in small increments. It should be noted that significant changes in formation characteristics due to stringers or faults may require frequent re-establishment of the operating parameters to maintain optimum penetration rates and directional control for each formation type. Other parameters which may affect and vary motor control include: • Downhole (formation) temperature changes. • Bit incompatibility with the formation or bit wear/damage. • Circulating fluid characteristics changes due to fluid/solids and gas influxes or additions. Maintaining a constant operating pressure differential, below the maximum specified, reduces orienting problems due to reactive torque fluctuations and allows greater control over avoiding motor stall. Stall occurs when, given specific operating parameters, the required torque at the bit is greater than that which the motor can

188

produce (See the motor specifications listings and performance graphs in Chapter Two for motor operating pressure differential data).

3.4 MOTOR MECHANICAL LOADING Motor mechanical loadings should be considered in detail during well planning and drilling operations to predict the effects of motor loadings on motor longevity, ROP and BHA directional performance. Sperry-Sun can undertake detailed analysis with respect to proposed drillstring rotation rates, bit, motor, stabilizer and BHA component geometries/physical properties and their relationships to wellbore geometry. For more detailed information see 4.13 and 4.14. SPERRY DRILL motors are designed to operate efficiently and reliably in the downhole environment when subjected to various surface-applied loadings such as WOB, torsion, rotation, overpull and jarring. Mechanical loadings may result downhole from BHA component interactions with the hole wall/formation (e.g. bits and stabilizers). Loadings are also generated and transmitted by motor internal components (e.g. reactive torque and bit side loading of the driveshaft). During motor component design, static and dynamic stress analysis aids in the development of component geometries and in materials selection. The analysis is based on the individual and cumulative effects of various motor loading parameters including compression, tension, torsion, bending, fatigue, internal pressure, shock and vibration loadings for both oriented and rotated drilling modes.

3.5 MOTOR REACTIVE TORQUE As a free-running SPERRY DRILL motor is lowered to the hole bottom and the drill bit contacts the formation, WOB is applied and power unit differential pressure rises due to torque being required at the bit to maintain rotation and penetrate the formation. The bit rotation is to the right if the motor is viewed from above the dump sub. The torque applied at the bit produces an equal reactive torque which acts, via the motor stator housing to the drillstring, in an opposite (counter-clockwise) or left hand direction. The required amount of torque at the bit is a function of the applied WOB and bit/formation interactions. As the amount of torque required to turn the bit reduces, the reactive torque (which tends to turn the drillstring to the left) reduces. As torque required to turn the bit increases, the reactive torque increases. The motor reactive torque, drillstring torsional and axial drag can be computer analyzed by Sperry-Sun. Angular drillstring offset for a given application can be approximated by obtaining the motor pressure differential between off-bottom No Load pressure and onbottom optimum running pressure. The pressure obtained is related to output torque for a particular motor (see 2.2 performance graphs). The reactive torque value is equivalent to the output torque value. Reactive torque is at a maximum during the stall condition, therefore angular drillstring offset (twist) is a maximum during the stall condition. This may necessitate modification of motor orientation.

190

Drillstring turn tendency effects the toolface; turn tendency should be considered in detail with respect to directional drilling operations to facilitate precise directional control (see Appendix ‘A’).

3.6 WEIGHT ON BIT Sperry-Sun recommends that the WOB be maintained at the minimum value, within the applicable range for a given motor application, which achieves acceptable ROP and/or directional performance. Increasing WOB applied to a motor normally results in an increased motor operating differential pressure and increased output torque. The amount of differential pressure which can be achieved and consequently the amount of weight a motor can operate with, while avoiding stall, depends on bit/formation interactions and related downhole parameters. For a given application it may not be possible to apply WOB values across the working range specified for a particular motor. This occurrence does not necessarily indicate a weak or worn motor. The application of excessive WOB, especially if combined with drillstring rotation, can result in accelerated wear of internal motor components and high level loading of the driveshaft, thrust bearings, motor housings and housing connections. High levels of WOB applied in overgauge holes can result in high motor component stress loadings which can lead to serious motor damage (See 4.13). It should be noted that while WOB may be low or virtually zero during reaming/circulating operations, drillstring rotation alone can place high mechanical loadings 191

It should be noted that while WOB may be low or virtually zero during reaming/circulating operations, drillstring rotation alone can place high mechanical loadings 191

on motors due to the physical constraints, or lack of constraints (overgauge hole) of wellbore geometries. WOB ranges are contained in the individual motor specifications listings in section 2.2.

3.7 MOTOR STALL Motor stall occurs when the combination of torque and RPM produced by the power unit is not sufficient to cause effective penetration of the formation with the drill bit. Stall may occur due to excessive application of WOB, excessive string RPM, sudden change of formation characteristics, bit wear/damage or a combination of any of the above. When the motor stalls the bit, drive shaft and rotor effectively lock-up and remain stationary, no penetration occurs and the circulating pressure rises rapidly due to the fluid seals present between the rotor and stator (see B.4). The pump pressure rises until the seals between the rotor and stator are broken, resulting in the passage of highly pressurized circulating fluid between the deformed lobes of the elastomeric stator and the lobes of the metallic rotor. (See Figure 4.13.) Note: During motor stall, the combination of mechanical loading and high pressure fluid erosion can quickly result in serious stator elastomer damage. During motor stall the operating pressure differential across the motor and the resulting stall torque (sometimes referred to as “maximum torque”, where there is no rotation of the bit) can rise to approximately 70% above the maximum operating torque. 192

* The High Motor Operating Pressure Zone shown occurs at high loadings where drilling conditions are less than optimum. Within this zone, wear rate and stall tendency is increased (See 2.1.1). Figure 3.7 (1)

In theory the increased differential pressure at stall acts internally on the drillpipe tending to cause the pipe to lengthen and WOB to increase. Should stall occur during drillstring rotation operations, the drillstring rotation causes the stator to be rotated over the stationary rotor. This increases the potential for serious elastomer damage. Such a situation can occur very rapidly during top drive motor drilling operations. Detailed attention must be given to avoid stall and stator rotation occurrence (See 4.13 & Chapter 2). The occurrence of motor stall is observed at surface by a standpipe pressure increase and zero ROP; do not wait to observe ROP if pressure gauges indicate a motor stall situation (see Figure 3.7 (1), above). 193

If a stall situation occurs, any string rotation should immediately be stopped. The string should also immediately be picked up off bottom, and pressure should be allowed to drop-off, thus re-establishing bit rotation.

under high loading conditions and/or with high drillstring rotation rates.

The operational parameters at the occurrence of motor stall should be considered and modified if necessary. WOB, flow rate, drillstring RPM and operating differential pressure parameters should all be carefully reestablished to achieve optimum ROP and/or directional performance.

Varying circulating fluid characteristics, due to the introduction of additives, formation fluids/gases or temperature changes, can affect stall differential pressure values.

Note: The increases seen in differential pressure above specified maximum operating pressure values, due to the onset of stall, vary between different power unit designs. The differential pressure increases caused by stalling also vary between power units of similar designs. This is due to differences in individual power unit mating fits, internal motor component size tolerances and operating temperatures. MICROSTALLING Under high loading conditions, short duration “micro” stalling may occur. Microstalling tends to have the same detrimental effects on the motor that full stalling does. During microstalling, the motor momentarily becomes stalled, the bit becomes stationary, and the stator, transmission unit, and driveshaft assembly are subjected to stall load. The bit then begins to rotate again, and the stall condition is removed. Micro stalls are of very short duration, and usually are not detectable at surface. Microstalling may occur repeatedly in applications where motors are operated 194

MOTOR STALL WITH JET NOZZLED ROTORS

The use of rotor jet nozzles modifies the operating characteristics of motors. Motors with jet nozzled rotors require more stringent operational control when difficult drilling conditions arise. The jet nozzle is sized to permit a specific amount of fluid to pass through it at a specific rotor/stator operating differential pressure; this is based on the required bit torque and rotation speed. Off-bottom circulating can result in excessively high flow rates between the rotor and stator which results in premature wear. The circulation rate should be reduced prior to lifting up off-bottom. The stalling of a motor with a jet nozzled rotor is not as apparent on the standpipe pressure gauge since the jet nozzle permits the passage of fluid through the rotor bore (referred to as a “soft stall”). Note that although, during soft stall mode, less fluid passes between the jet nozzled rotor and the stator, the soft stall mode is still potentially damaging to a motor. Motor stall with a jet nozzled rotor is characterized by an increase in differential pressure and no ROP. To avoid excessive flow/rotation, the circulation rate should be reduced prior to lifting up off bottom after motor stall is recognized (For more detail, see 4.6). 195

If a stall situation occurs, any string rotation should immediately be stopped. The string should also immediately be picked up off bottom, and pressure should be allowed to drop-off, thus re-establishing bit rotation.

3.8 HYDRAULIC CONSIDERATIONS Use of the SPERRY DRILL motor introduces an additional pressure loss to the drilling hydraulic system, due to frictional losses in the motor power unit and internal components below the power unit (frictional losses in components below the power unit are minimized.). Circulating fluid pressure losses are minimized by designing the fluid flow path to be smoothly transitioned, and as free of path obstructions as possible.

Motor No Load and Operating Differential pressures may vary due to the effects of a number of parameters (see Chapter 2 & 3.2). Operating Differential pressures may be obtained from the motor performance graphs (see 2.2). BHA component internal pressure losses can be obtained direct from equipment manufacturers or can be calculated from manufacturers data.

A SPERRY DRILL motor hydraulics plan would typically consider the pressure losses due to all surface and downhole drilling system components.

Some SPERRY DRILL motors can be specially configured to run with drill bit pressures of up to 1,500 psi as required by bit hydraulics. For a given flow rate approximately 5 to 8% of the circulating fluid passes through the bearing assembly for lubrication and cooling purposes. 92 to 95% of the total circulating fluid flow is available at the bit; this value for fluid flow should be used to calculate the bit pressure drop. Bit hydraulics should be maintained with respect to the manufacturers specifications. A general guideline for tricone bits is to maintain the jet velocity at around 300 feet per second. For PDC bits the horsepower per square inch (HSI) should be in the range 2.5 to 7. A rule of thumb for annular fluid velocity is 100 feet per minute with the flow being laminar over the drillpipe. Running high (greater than 500 psi) bit pressure drops with “low pressure” flow restrictors allows too much fluid to pass across the bearings and can wash out the bearings (this can occur due to bit plugging). Running low (less than 300 psi) bit pressure drops with “high pressure” flow restrictors causes too little fluid to pass across the bearings and can result in over-heating and wear of the bearings.

4.1 OVERVIEW This section details the rig-site inspection, testing and operation of SPERRY DRILL motors to ensure the efficient achievement of drilling objectives while maximizing motor longevity. Various factors can contribute toward and should be considered with respect to motor component wear or damage, including: • Excessive operating temperature, flow rate, drillstring rotation, WOB, motor operating differential pressure, bit differential pressure and wellbore dogleg. • Adverse effects caused by circulating fluid chemicals, sand/solids content. New motors should initially be run at reduced rates to allow components to seat and ensure that all operating parameters are within established guidelines.

4.2 MOTOR CONFIGURATION INSPECTION & REPORTING The following information should be recorded prior to motor operations: • • • • • • • • 200

Motor Type/Size (check against shipping documents) Motor Serial Number (located on stator housing) Dump Sub Fitted? Stabilizer Type/Size (including blade information) Adjustable Housing Angle Fixed Bent Housing Angle Rotor Jet Nozzle Size (if any) Bearing Configuration (painted on new motors)

• Visually check general condition of motor housings, top and bit connections, bent housing/adjustable housing and stabilizer or protector sleeve. • Lengths between Bit Box to Stabilizer, Stabilizer to Bent Housing/Adjustable Housing, Bent Housing/Adjustable Housing to Connection at bottom of dump sub, connection at bottom of dump sub to top of motor.

4.3 PRE-RUN MOTOR SURFACE TESTS To assist in the assessment of motor performance, condition and problem diagnosis, a number of basic motor tests should be performed before and after (see 4.17) operation downhole. Note: For correct motor operation, pressure, WOB, flow rate, string RPM, and gauging must be accurate. Pulsation dampeners must be in good working order. If a significant period of time has passed since a used motor was last tested after a previous run, and the motor was not flushed with water/oil, it should be re-tested prior to use. A.

Check the operation of the dump sub by moving the sliding piston with the aid of a wooden drift (do not use a metallic drift).

B.

Pick up the SPERRY DRILL motor using a lifting sub and lower it until the dump sub is below the rotary table. Make the motor up using the kelly or rig to drive, then lift the motor free of the slips.

Pick up the SPERRY DRILL motor using a lifting sub and lower it until the dump sub is below the rotary table. Make the motor up using the kelly or rig to drive, then lift the motor free of the slips.

201

Note: Avoid possible bit damage by testing the motor without the bit attached. (A thread protector should be placed in the bit box during lifting operations and removed prior to flow testing.) Prolonged running with no bit, or at very low flow rates should be avoided to minimize bearing assembly heating. C.

D.

Gradually raise the flow rate to the minimum specified rate for the particular SPERRY DRILL motor and record flow rate and corresponding pressure (if possible, record the flow rate and corresponding pressure at which the dump sub valve closes). If possible, further raise the pump flow rate and record the flow rate and corresponding pressure. A relatively high level of vibration and noise can occur during testing; vibration and noise are inherent to the motor design.

Note: When considered on their own, motor No Load pressure values, the draining of drilling fluid from the bit/driveshaft and the amount of resistance to the manual rotation of motor drive shafts, are not reliable guides to motor condition and performance downhole. Motors are designed to operate downhole at higher temperatures than at surface. Motors are configured with mating part fits which provide allowance for thermal expansion of components such as the elastomer (rubber) stator. At surface temperature a motors No Load pressure, its resistance to manual driveshaft rotation and its rotor/stator fluid sealing capacity are less than when the motor is at downhole temperature. 202

Motors are heated externally by the formation and internally by the action of the rotor running in the stator. E.

With the pumps still running, raise the dump sub above the rotary table and inspect the fluid ports for leakage (clean the housing/ports for ease of observation). Further raise the motor to observe the bearing assembly fluid leakage over the rotating drive shaft (5-8% of total flow rate is acceptable). Observe drive shaft rotation which should not be erratic. Lower the dump sub below the rotary table, stop the pumps and allow the dump sub to open (which may require opening of surface equipment bleed valve due to pressure lock). Raise the motor above the rotary table and perform the thrust bearing gap (play) check as outlined in section 1.8. Adhere to the thrust bearing axial play specifications detailed in the table in section 1.8. Radial bearing play can be checked by placing a chain tong on the bit box and applying side loading to the drive shaft. On a new motor, radial bearing float should be negligible. The bit is made up by locating the make-up tong on the motor bit box (rotating component) and the bit breaker on the bit. The play in the thrust bearing assembly should be checked on both new and used motors. A number of bearing assembly options are available for SPERRY DRILL motors.

4.6 ROTOR JET NOZZLING

4.6.1 ROTOR JETTING OVERVIEW

Rotor jet nozzling may be used to provide for motor operating flow rates which are greater than the maximum flow rate normally specified for a specific motor type. Only a limited amount of excess flow can be accommodated by using rotor jet nozzles.

Jet Nozzle

Rotor

Stator

Rotor jet nozzling is also used where there are concerns regarding demanding drilling conditions causing motor stalling, which can lead to stator elastomer damage occurring (Motors of 3-1/8” diameter and larger can be configured with rotor jet nozzles).

Stator Housing

Excessive operating flow rates reduce rotor/stator efficiency and promote accelerated rotor and stator wear. The jet nozzle is positioned at the top of the rotor. The nozzle size is carefully selected for specific applications.

Rotor Bore

When the drilling mud enters the top of a jetted motor it can either pass between the rotor and stator developing power or it can simply bypass the stator through the bore of the rotor. Fluid Ports Transmission Connection

Figure 4.6.1 (1)

210

The pressure drop across the rotor and stator and the pressure drop across the rotor jet nozzle are the same. This pressure drop is equal to the pressure required to start the motor and maintain output power at a specific level. Since the pressure drops across both paths are always equal, if the pressure drop across the rotor and stator is high, then the flow rate through the jet nozzle is high. If the pressure drop across the rotor and stator is low then the flow rate through the jet nozzle is low.

This pressure drop is equal to the pressure required to start the motor and maintain output power at a specific level. Since the pressure drops across both paths are always equal, if the pressure drop across the rotor and stator is high, then the flow rate through the jet nozzle is high. If the pressure drop across the rotor and stator is low then the flow rate through the jet nozzle is low.

211

Advantages Of Rotor Jetting: Rotor jet nozzling allows the flow rate limit for a specific motor to be exceeded by a limited amount. Should a jet nozzled motor stall, the jet nozzle effectively protects the stator elastomer by diverting more of the drilling mud away from the rotor and stator lobes, reffered to as “soft stall”. The operating differential pressure to output torque relationship is not affected by jet nozzling. Disadvantages Of Rotor Jetting: For a given jet size, exactly how much drilling mud is bypassed is governed by operating differential pressure. Care must be taken to avoid overspeeding jet nozzled motors when picking up off bottom or circulating. With only low No Load differential pressure acting at the jet, very little flow will bypass the rotor and stator.

The mud weight directly affects the pressure drop across the rotor jet nozzle, this must be taken into account.

Note: The minimum flow rate between the rotor and stator should not be less than two thirds of the maximum recommended flow rate for the specific motor model.

Refer to Figure 4.6.2 (1).

The Total Pressure required to operate the motor and provide power to the bit is the sum of the No Load plus the Operating Differential Pressures, (for No Load and Operating Differential pressure information see 2.1.2).

4.7 FLOAT VALVES A float valve may be run above the motor to avoid potential fouling of the motor and bit with solids. Use of a float valve is recommended when drilling unconsolidated formations, drilling underbalanced or milling steel. Should a float valve not be available, fluid should be displaced regularly while tripping in hole.

4.8 DRILLPIPE FILTERS To minimize the potential for damage to motor components from solids and foreign objects in the circulating fluid, it is recommended that surface drillpipe filters be utilized during motor operations. (This includes tripping in hole operations). Any appreciable solids/foreign objects should be observed and noted and the necessary corrective action taken. Note: Attention should be given to the observation of solids/foreign objects at the shakers.

Tight spots can cause high contact 221

forces on the periphery of the bit, requiring significant torque output levels from the motor. Reciprocate the string if required, stopping at differing depths to avoid creating ledges. When rotating the drillstring, caution must be shown with respect to bent subs, bent housings, motor stabilizers and housing configurations since excessive drillstring rotation and the effects of hole constraints can cause high-level cyclic loading of motor housings and connections (see 3.13). Avoid running the bit into any settled solids or hole bottom. At a short distance above any settled solids, slowly raise the flow rate to the planned motor operating rate and establish circulation (reciprocate the string if necessary) to remove the settled solids.

4.11 INITIAL SPERRY DRILL MOTOR OPERATIONS (OFF BOTTOM) Having tagged hole bottom, pick up off bottom and record pick-up/slack-off weights and rotary torque values. Gradually increase flow rate to the minimum operating flow rate and record the “off-bottom” or “No Load” pressure (see 2.1.2). This pressure is used as a reference from which motor operating differential pressure and therefore torque can be calculated (see 3.7). Bit rotation speed can be readily approximated using the performance graph for a particular motor (see 2.2). During drilling operations, the off-bottom reference pressure should be checked periodically to allow for circulating fluid rheology changes, increased hole depth or any changes in flow rate.

222

4.12 GENERAL MOTOR CAPABILITIES & CONSIDERATIONS Always start the pumps before string rotation; start the pumps and rotate the string before going on hole bottom. Do not adjust string rotation speed while the motor is operating on bottom. With the motor off the hole bottom, start the pumps and gradually raise the flow rate to the planned operating value, slowly lower the string and apply WOB. As the bit contacts the formation, torque is required to maintain and penetrate the formation; this increases the pump pressure. Increasing WOB increases the pump pressure and decreasing WOB reduces it. Note: Consideration should be given to running a new motor “in” for 10-15 minutes at reduced operating parameters. During this initial period, ROP may be slow and erratic. The string should be periodically lifted off bottom to ensure cuttings cleaning. PDC and diamond bits should initially be run at as low bit weights as possible, increasing weight as the job progresses, until the optimum weight is achieved. Tri-Cone bits typically have less frictional drag losses than PDC or diamond bits. Therefore, operating differential pressures are less given similar formation and operating parameters.

4.13 ROTATION OF DRILLSTRING/MOTOR 4.13.1 GENERAL Drillstring rotation is used during motor drilling to optimize operating parameters such as penetration rate and hole cleaning. It is essential that the use of drillstring rotation is closely controlled and monitored. Drillstring rotation increases the cumulative mechanical loads on many motor components above those encountered during motor operations with no drillstring rotation. Excessive drillstring rotation rates can promote accelerated wear of rotors and stators, cause belling of threaded connections and increase cyclic fatigue of motor components in straight and bent motors. Aggressive doglegs, inadequate BHA stabilization, excessively overgauge holes and inefficient hole cleaning can contribute to the cyclic fatigue of straight and bent motors at relatively low drillstring rotation rates. As a motor is rotated, components such as the tubular housings and driveshaft have stresses applied to them as a result of the motor and BHA components contacting, and being constrained by, the hole wall. In severely overgauge holes there is a lack of constraint of the motor/BHA components. This permits excessive lateral movement of these components, which can induce high stress levels into them. Drillstring rotation can cause component outer surface wear and heat checking (steel heating and quenching) at any location where there is an excessive reaction between the motor and either the borehole wall or a cuttings bed. 224

Exact values regarding maximum motor rotation rates, which incorporate factors of safety, cannot be specified due to the variance in cumulative motor loadings which are experienced in individual motor applications. During motor drilling or reaming operations, areas of severe doglegs and overgauge hole should be noted. When the motor is at these locations, drillstring rotation rates and applied weight on bit should be regulated to minimize the levels of stress applied to the motor.

4.13.2 CYCLIC LOADING OF MOTORS During operations with drillstring rotation the stress levels in individual motor/BHA components fluctuate in relation to the position of the component within the local hole geometry. During each rotation of the drillstring, stresses in components can cycle between compression and tension. The greater the motor bend setting, the greater the fluctuation. BHA and motor connection failures are almost always due to fatigue, since the stress reversal level required to cause fatigue is significantly lower than the tensile yield point of a component. Motor component failure which is primarily caused by bending or torsion is uncommon. The number of cycles required to cause fatigue failure of a component can be approximated under laboratory conditions. However, the variable nature of (amongst others) hole geometry, motor component interaction with the hole wall and bit load, makes exact “cycle to failure” calculation impossible. For steel there is a critical stress, called the “endurance limit”. If stress levels are maintained below this level, fatigue will not occur regardless of the number of

For steel there is a critical stress, called the “endurance limit”. If stress levels are maintained below this level, fatigue will not occur regardless of the number of

225

cycles applied to the component. When the fluctuating stress level is greater than the endurance limit the component will crack after a specific number of cycles. If cyclic stressing is continued once a crack is initiated, the crack will grow until the material in the location of the crack cannot carry the applied loads, and the component will then fail. SPERRY DRILL motor component materials and geometries are selected to maximize the endurance limit and fatigue resistance of each component. Load characterization for the range of SPERRY DRILL motor housings has been undertaken using a variety of BHA analysis programs. For the purpose of these analyses, each of the major sections of the motor (bearing housing, offset housing adapter, stator, dump and saver subs) was equated to a cylinder of equivalent mean stiffness. Bending moments were computed for each motor in both the 0° toolface (“happy”), and 180° toolface (“unhappy”) orientations. Stress levels at specific areas of the motor housings were then derived from the bending moment values. The Sperry-Sun WHIRL software program has also been utilized to provide further insight into the dynamic loading of motor housings and BHAs. A close correlation has been demonstrated between WHIRL program output and data supplied from the Sperry-Sun DDS downhole vibration sensor. A series of full scale tensile pull tests have been completed to determine the failure strength of motor bent housings when acted upon by simultaneous tensile and bending loads. 226

4.13.3 MOTOR FUNCTIONING WITH DRILLSTRING ROTATION In rotary drilling operations, a variation in torque available at the bit may arise as a function of dynamic changes in drillstring frictional losses. These losses are directly related to hole geometry, hole condition and drilling fluid properties. Fluctuations of, and differences between, the torque required at the bit and the torque available at the bit, can cause a condition known as “stick-slip” to occur. During “stick-slip”, bit rotation speed can become far greater or less than that of the drillstring; at times rotation can stop completely. Reverse bit rotation and severe torsional loading of the drillstring and BHA components may occur as a consequence. There may not be any surface indication that this is happening. Drillstring stick-slip can sometimes be noted by observing reactive torque fluctuations, under such conditions the torque fluctuations may be accompanied by a corresponding fluctuation in rotary speed. During motor drilling operations with drillstring rotation applied, the rotary torque is transmitted to the bit via the rotor and stator. In this way the rotor/stator combination effectively acts as a torsional shock absorber. When very high levels of torsion are momentarily applied to the rotor and stator from the drillstring, the rotor tends to “slip” a discrete amount within the stator and some of the torsional load is absorbed by the stator elastomer. If the motor is routinely run with excessive drillstring 227

If the motor is routinely run with excessive drillstring 227

rotation then the incidence of rotor slip will be greatly increased, leading directly to stator overloading and premature failure.

4.13.4 POWER UNIT FUNCTIONING WITH DRILLSTRING ROTATION In theory the amount of torque that can be transmitted by a power unit rotor and stator is independent of the drillstring rotation rate. The bit rotation rate results from the addition of the drillstring rotation rate and the actual motor output RPM for a given operating pressure/flow rate. The amount of torque that can be transmitted by a power section is dependent on the mechanical and hydraulic forces produced between the rotor and stator during motor operation. The mechanical forces relate to lobe geometry, properties of the rotor/stator materials, rotor/stator mating fit and drilling fluid lubricating properties. The hydraulic resistance relates to the action of the pressurized drilling fluid as it passes through the cavities between the rotor and stator. The hydraulic energy of the drilling fluid is effectively converted to mechanical energy during rotor/stator functioning. The directional driller controls the operating pressure/torque across the motor, whether the drillstring is rotated or not. In theory the control of motor operating pressure/torque is similar whether the drillstring is rotated or not (see B.4).

228

4.13.5 DRILLSTRING ROTATION RATE CONSIDERATIONS WITH RESPECT TO THE POWER UNIT See Figure 4.13.5 (1) on the next page. Excessive drillstring rotation rates for given drilling conditions can cause severe dynamic mechanical loading of the rotor/stator pair. In some circumstances the cumulative dynamic mechanical loading can cause excessive rotor slippage and effect the seal between the rotor and stator. Excessive rotor slippage can cause wear, heating and “chunking” damage to the stator elastomer. Reduced sealing efficiency results in fluid leakage from the cavities between the rotor and stator, necessitating the application of increased loads across the power section in order to maintain motor output levels. This can further promote erosion, wear and damage to the elastomer. Should excessive drillstring rotation rates produce dynamic mechanical loads which adversely affect the rotor/stator seals, the effective working envelope of the motor may be reduced. This in turn makes the motor more liable to stalling and reduces the ability of the directional driller to exercise effective control over toolface direction. Excessive drillstring rotation rates for specific conditions may promote short-duration “micro” stalling. Microstalling may not be detectable at surface, however it tends to cause the same detrimental effects on the motor that “full” stalling does (see 3.7).

4.13.6 MOTOR VIBRATION CONSIDERATIONS SPERRY DRILL motor vibration should be considered with respect to the following motor applications: • Oriented mode — drillstring static • Rotary mode — drillstring rotating During motor operations there are three types of vibration present: • Axial • Torsional • Transverse/Lateral All three vibration types originate from two or three separate sources, depending on whether in oriented or rotary drilling mode. The sources are the drill bit, SPERRY DRILL motor and the drillstring /BHA. Prediction of drill bit, SPERRY DRILL motor and drillstring/BHA vibrations is a complex matter. Axial and torsional vibrations may be coupled and effects such as “stick-slip” can amplify the effect. The problem is further complicated when considering drillpipe bounce, BHA/wall contact, bit whirl and hole spiralling. Precise vibration analysis is impossible, due to the difficulties in accurately modelling individual borehole contact points and loads, drill bit/formation interactions, and internal motor component dynamic behavior. Motors with bent housings and stabilizers can complicate vibration analysis due to the whirling motion during drillstring rotation. Comprehensive vibration analysis must also consider bent sub, eccentric housing and kick pad effects. 231

4.13.6 MOTOR VIBRATION CONSIDERATIONS SPERRY DRILL motor vibration should be considered with respect to the following motor applications: • Oriented mode — drillstring static • Rotary mode — drillstring rotating During motor operations there are three types of vibration present: • Axial • Torsional • Transverse/Lateral All three vibration types originate from two or three separate sources, depending on whether in oriented or rotary drilling mode. The sources are the drill bit, SPERRY DRILL motor and the drillstring /BHA. Prediction of drill bit, SPERRY DRILL motor and drillstring/BHA vibrations is a complex matter. Axial and torsional vibrations may be coupled and effects such as “stick-slip” can amplify the effect. The problem is further complicated when considering drillpipe bounce, BHA/wall contact, bit whirl and hole spiralling. Precise vibration analysis is impossible, due to the difficulties in accurately modelling individual borehole contact points and loads, drill bit/formation interactions, and internal motor component dynamic behavior. Motors with bent housings and stabilizers can complicate vibration analysis due to the whirling motion during drillstring rotation. Comprehensive vibration analysis must also consider bent sub, eccentric housing and kick pad effects. 231

During motor operations there are various external sources which reduce vibration, including viscous dampening by the drilling fluid and radiation of acoustic waves into the formation. Severe vibration can occur when the combination of drillstring and bit vibrations interact with motor vibrations to produce resonant frequencies. Resonance, or frequency tuning, exists when the frequency of the applied force is equal to the natural free vibration frequency of a component or assembly. Such behaviour occurs at critical rotor and drillstring rotational speeds, which should be avoided. The results of severe vibration are reduced drilling efficiency, reduced BHA component life (including motors and MWD systems) and increased frequency of threaded connection failure. ROP may actually increase in hard formations as a result of severe vibration. This, however, is usually also associated with BHA component wear and failures. Severe vibration may not be detectable at surface in real time. Difficulty in achieving MWD signals may be an initial indicator of the occurrence of severe vibration. The Sperry-Sun WHIRL software program has been used to provide further insight into the dynamic loading of motor housings and BHAs. A close correlation has been shown between the WHIRL program predictions and data supplied by the Sperry-Sun DDS downhole vibration sensor.

DOGLEG PREDICTION & DRILLSTRING ROTATION RATE VS BENT HOUSING ANGLE

The Dogleg Prediction and Drillstring Rotation Rate versus Bent Housing Angle charts in 1.10 were generated from detailed stress analysis of the motors and limit the bending stress in the motor connections with respect to the “Endurance Limit” of the steel used. The Endurance Limit is the stress below which a crack will not start under the alternating bending stress caused by rotating a motor with a bent housing. Should a crack be initiated a finite number of “cycles to failure” applies, this is determined by the drillstring rotation rate: the higher the drillstring rotation rate the sooner the failure will occur. The key, therefore, is to minimize the bending stress by using the minimum bent housing setting and drillstring rotation rate required for acceptable directional control and hole cleaning. Drilling involves compromise: if higher drillstring rotation speeds are shown to be necessary, reducing the bent housing size may allow this. Formation characteristics have direct effects. If the formation is soft, there is less likelihood that high drillstring rotation rates will cause problems than if the formation is hard. If high drillstring rotation rates are considered essential at the planning stage, some motors can be specially configured to suit. Contact Sperry Sun. For related information see 3.4, 4.13 and B.7

WHIRL predictions have proven that resonance has been the cause of past mechanical tool problems. Data produced by WHIRL is used to modify the specific drilling parameters, which may cause excessive loads on the motor and BHA. 232

4.15 TORQUE TESTING MOTORS IN THE FIELD The practice of motor field torque testing is not recommended. It must not be performed unless directly authorized by SPERRY DRILL motor Operations Support Group. Serious motor component damage can result due to the motor going into and being held in the stall mode. The practice is potentially dangerous. Since motors are configured to work downhole at higher temperatures than at surface, allowing for component expansion due to heat, surface torque values will always be substantially lower than drilling torque values.

4.16 TRIPPING OUT OF THE HOLE Prior to tripping out of hole, circulate the hole clean by reciprocating the drillstring to approximately 30 feet from hole bottom, picking the string up slowly and lowering at a slightly faster rate. Should motor configuration and hole geometry permit, drillstring rotation (typically 20 - 30 RPM or higher) can be applied when circulating the hole clean. Lower and raise the drillstring to differing depths to avoid creating ledges. During tripping out operations, the drillstring can be rotated at low rates. Caution: Avoid any motor or bit contact at the casing shoes. Consideration should be given to the well profile and any known problem zones. Should the drillstring hang-up, lower and then rotate the string at low string rotation rates. Pick up at slow speeds and reciprocate the string if required.

234

If it becomes necessary to pull on the drillstring, refer to Chapter 2 for the individual motor specifications and maximum motor overpull values. (Also see 4.17)

4.17 POST-RUN MOTOR SURFACE TEST Post-run surface tests can provide useful information regarding motor component condition. Complete postrun surface tests should ideally repeat the pre-run surface tests thus permitting full test result comparisons to be made (see 4.3). Note: When considered on their own, motor No Load pressure values, the draining of drilling fluid from the bit/driveshaft, and the amount of resistance to the manual rotation of motor driveshafts are not reliable guides to motor condition and performance downhole. Motors are designed to operate downhole at higher temperatures than at surface. Motors are configured with mating part fits which provide allowance for thermal expansion of components such as the elastomer (rubber) stator. At surface temperature a motors No Load pressure, its resistance to manual driveshaft rotation and its rotor/stator fluid sealing capacity are less than when the motor is at downhole temperature. Motors are heated externally by the formation and internally by the action of the rotor running in the stator. Rig site operations may dictate that the post-run surface tests are not conducted. Should this be the case, motor surface tests must be performed when the motor is considered/picked up for a subsequent application.

4.18 MOTOR OPERATIONS DATA REPORTING

Circulating fluid should be drained from the motor by holding the motor housings stationary and rotating the drive shaft clockwise (to the right when looking down from the top of the dump sub). This can be accomplished using chain tongs or the break-out tong and bit breaker/rotary table. This operation may also permit limited assessment of rotor/stator interference and correct movement of the driveshaft in the bearing assembly. The dump sub should be flushed with fresh water and any debris removed from the fluid port filters. Water should be applied with a hose at the box connection and be permitted to flow from the bearing assembly (over the driveshaft).

To facilitate the effective appraisal of motor operations, to provide a database of information for subsequent well planning and motor design development, and to aid in drilling problem analysis, it is essential that comprehensive motor operations reports are completed.

Flush clean hydraulic oil such as Shell Tellus Grade R1-10 or equivalent through the motor to inhibit any adverse chemical reactions to motor components during motor storage or transportation. DO NOT use petroleum-based oil. Manually check the operation of the dump sub by moving the sliding piston with the aid of a wooden drift (do not use a metallic drift). A correct size thread protector in good condition should have thread dope applied and be fitted to the motor bit box to protect the connection threads and shoulder face. A SPERRY DRILL motor lifting sub should have thread dope applied and be made-up to the motor inlet (top) connection. (See 1.4)

SPERRY DRILL motor operations reports (MPRs) are an integral part of the directional drilling supervisor’s reporting system. Data is transferred to a central collection center for database input and analysis.

4.19 OVERPULL AND JARRING If the drillstring or bit becomes stuck during drilling or tripping operations, normal drillstring freeing operations should be performed with respect to the following: For straight motors in straight hole applications permissible overpull values which may be applied to the motor housings or bit, and therefore driveshaft and thrust bearings, can be obtained from Chapter 2. Two values are given for each case; not exceeding the Continued Operations value during overpull operations permits the motor to be re-used. Should the Continued Operations value be exceeded, the motor must be returned to Sperry-Sun for detailed inspection. The Ultimate Loading values are the absolute maximum loads which may be applied to a motor while avoiding irreparable damage. The application of high overpull loads on bent housing motors, particularly in doglegs, can result in high bending stress levels in motor housings and connections. If possible, bent housing motors should be oriented high

side in doglegs, prior to the application of overpull loads. In high dogleg situations, the SPERRY DRILL motor Operations Support Group should be contacted to obtain correct overpull values. High overpull loads applied in overgauge holes can result in serious motor damage. As with drillstring rotation rate guidelines, exact values for overpull loads, which incorporate factors of safety, cannot be defined due to the variance in cumulative loading effects for individual motor applications. Jarring operations are permissible with the use of SPERRY DRILL motors. However, the variable and unquantifiable nature of many downhole motor loading parameters, differences in jar types, variations in magnitudes of jarring loads and jar placement in BHAs with respect to motors, prohibits the publishing of generalized acceptable jarring operations data. Jarring loads can induce high tensile and compressive shock loadings on motor internal components and housings. A jarring load is typically a number of magnitudes higher than the overpull load applied to actuate the jar. Jarring down in overgauge hole can result in serious motor housing damage due to buckling.

offer the highest level of chemical and abrasion resistance while maintaining acceptable mechanical properties at downhole drilling temperatures. The ingredients of the elastomers and the processing methods are varied to produce different “as moulded” stator elastomer characteristics. The different characteristics of the elastomers allow for reliable operation of SPERRY DRILL motors in widely varying drilling conditions.

Each elastomer type has its own downhole operating envelope which is related to the actions of drilling fluid chemicals, formation heat, internally generated heat, and mechanical loadings from the rotors. The stator elastomers have been selected to provide a degree of overlap in their operating envelopes. This provides for elastomer “options” being available to suit the majority of motor drilling application types. “Standard Service” elastomer options are utilized in the majority of motor applications. For some specific applications, “Special Service” elastomers are utilized. These have enhanced chemical and mechanical characteristics. The response of the elastomers to the downhole environment governs their effectiveness in sealing and bearing loads, as well as their resistance to wear or damage. This response depends on the elastomer microstructure. No single elastomer is suited for all motor applications. This is due to the variable combined actions of many changeable downhole parameters (e.g. drilling fluid 245

offer the highest level of chemical and abrasion resistance while maintaining acceptable mechanical properties at downhole drilling temperatures. The ingredients of the elastomers and the processing methods are varied to produce different “as moulded” stator elastomer characteristics. The different characteristics of the elastomers allow for reliable operation of SPERRY DRILL motors in widely varying drilling conditions.

Each elastomer type has its own downhole operating envelope which is related to the actions of drilling fluid chemicals, formation heat, internally generated heat, and mechanical loadings from the rotors. The stator elastomers have been selected to provide a degree of overlap in their operating envelopes. This provides for elastomer “options” being available to suit the majority of motor drilling application types. “Standard Service” elastomer options are utilized in the majority of motor applications. For some specific applications, “Special Service” elastomers are utilized. These have enhanced chemical and mechanical characteristics. The response of the elastomers to the downhole environment governs their effectiveness in sealing and bearing loads, as well as their resistance to wear or damage. This response depends on the elastomer microstructure. No single elastomer is suited for all motor applications. This is due to the variable combined actions of many changeable downhole parameters (e.g. drilling fluid 245

chemicals, temperatures and mechanical loadings). The performance of the elastomers is related directly to drilling conditions in a specific application. Standard Service elastomers may perform as well as the Special Service elastomers in some higher temperature and/or aggressive drilling fluid applications. New and more advanced rotor/stator designs and materials are constantly being developed in order to increase the downhole operating envelopes, reliability, and longevity of the motors. DRILLING FLUIDS/ELASTOMER COMPATIBILITY Downhole temperature and pressure variances and combinations can vary the actions of the drilling fluid with respect to motor performance, component wear and potential motor component damage. The effects that drilling fluid chemicals, downhole temperatures and dynamic mechanical loading may have, either individually or in combination, on elastomeric components are very complex. Drilling fluid/elastomer compatibility tests are continually undertaken by Sperry-Sun to provide data prior to specific motor drilling applications and to aid in elastomer component developments. The testing, which simulates downhole operating conditions, conforms to recognized elastomer industry standards and to the specific functional requirements of elastomer components as utilized in drilling motors. The tests are conducted at temperatures similar to downhole operating temperatures using actual field 246

fluid samples, laboratory prepared system samples and base fluid samples. Once aged, the elastomer test samples are inspected and mechanically tested. Changes in various elastomer properties are assessed by relating to un-aged reference sample values, to prior test data and to prior similar motor applications data. ANILINE POINT The Aniline Point of circulating fluids has generally been used as an indicator of the tendency of a circulating fluid to degrade elastomer components. Aniline Point is the temperature at which a specific volume of aniline completely dissolves in a similar volume of drilling fluid sample. This gives a general indication of the temperature at which there may be a tendency for some of the drilling fluid chemicals to dissolve into the elastomer, where it may change the elastomers physical properties (e.g. softening and swelling). Sperry-Sun recommends that oil-based drilling fluids have the highest possible aniline point temperatures in order to minimize elastomer component degradation tendency. Values of 165°F (74°C) and above are recommended. Ideally, drilling fluid aniline point temperatures should be higher than downhole operating temperatures. Note: Operating motors at temperatures above the Aniline Point temperature of a specific fluid does not necessarily result in elastomer-related problems. Aniline Point guidelines may not apply to many of the newer drilling fluid systems being used.

NEW DRILLING FLUIDS The highly toxic diesel-based drilling fluids once widely used have generally been replaced by low toxicity systems which have much lower aromatic content levels. The use of drilling fluids with significant aromatic content is not recommended. Low toxicity drilling fluids are generally compatible with SPERRY DRILL motor elastomer components for common downhole operating temperature ranges. Ester and ether based drilling fluids are generally compatible with SPERRY DRILL motor elastomer components with respect to commonly encountered downhole operating temperature ranges. It is recommended that low toxicity and ester/etherbased drilling fluids not previously tested or used with SPERRY DRILL motors are tested with respect to elastomer compatibility under simulated downhole conditions (See 4.22 for more circulating fluid information.). MOTOR OPERATING TEMPERATURE AND PRESSURE DATA Whether operational or static downhole, there are many parameters present which can tend to effect motor performance and longevity. Since the circulating fluid, operating temperature, internal operating pressure and hydrostatic pressure act upon motor components, the effects of these parameters and their interactions must be considered. Under the pressures normally experienced during drilling operations, the elastomeric motor components are considered to be incompressible due to hydrostatic and internal operating pressure effects alone. 248

High downhole temperatures can effect the mating fit between the rotor and stator. Rotor/stator mating fits (standard fit, oversize fit, double oversize fit, etc.) and geometries are selected to accommodate downhole operating temperatures. Motors configured for operations at high downhole temperatures are reffered to as “temperature compensated” motors. Motor operating pressure adjustments and special operations procedures are recommended in high temperature conditions (see Figures 1.7 (1), 1.7 (2), 1.7 (3), B.4 and 2.1 (2)). When running a motor into elevated temperature boreholes, periodic stops should be made to circulate until reduced temperature fluid passes through the motor. Stops for circulation should commence prior to reaching a depth at which downhole temperature is approximately 212°F (100°C). Continuous circulation normally maintains the mud system at reduced temperature; periods of no circulation should be minimized. The temperature drop between static and circulating conditions is dependent on specific hole and circulating fluid characteristics. Motors run at elevated temperatures should be run at the minimum differential pressure required to achieve acceptable ROP and/or directional performance. DOWNHOLE TEMPERATURE Should detailed downhole temperature offset data not be available, accurate downhole operating temperatures can be difficult to estimate. This is due to the differing thermal characteristics of the formation types to be drilled and of the drilling fluids, cements (cement geometries) and casings to be used. 249

Downhole operating temperatures can be further affected by the overall geometry of wells and by increased frictional losses caused by the application of drillstring rotation.

Downhole static and dynamic temperatures and the difference between both are application specific.

Power units manufactured from the Standard and Special Service elastomer types can have their temperature operating ranges modified for specific applications by adjusting the rotor/stator geometry and mating fit (standard size, oversize, double oversize, etc.).

Correct pre-planning provides allowance for adverse temperature effects on motors. This includes the surface conditioning of motors in extremely low temperatures after periods of storage. SPECIAL SERVICE MOTORS To further extend the operating range of “Standard Service” SPERRY DRILL motors, Special Service stator elastomers were developed. The Special Service motors offer the same operational and input/output characteristics as the equivalent Standard Service motors to a maximum temperature of 320°F (160°C). Each Special Service motor power unit is accurately sized to provide reliable optimum performance at the required operating temperatures. All motors utilize high temperature resistant seals, orings, radial bearing elastomer and lubricating oil. As with standard motors run at elevated temperatures, Sperry-Sun recommends that oil-based circulating fluids utilized with Special Service motors have the highest possible aniline point temperature, thus minimizing the possibility of any elastomer component degradation. Reduced motor operating differential pressures and special operations procedures are recommended in very 250

TEMPERATURE COMPENSATED MOTORS

The geometry and fit changes compensate for high temperature effects and ensure optimum stator elastomer loading. The modifications are made with respect to stringent tolerancing. Temperature Compensated motors are only recommended for use at and above the upper operating temperature ranges of the Standard and Special Service motors (see Figures 1.7 (1), 1.7 (2), and 1.7 (3)).

MOTOR OPERATING TEMPERATURE LIMITATIONS STANDARD SERVICE, SPECIAL SERVICE, AND TEMPERATURE COMPENSATED MOTORS Standard Service motors are rated to operate to a maximum downhole circulating temperature of 210°F (99°C). Above 130°F (54°C), reduced differential pressure operating parameters apply. Standard Service motors, which have been thermally modified (Temperature Compensated) to extend their operating range, are rated to operate to a maximum downhole circulating temperature of 300°F (149°C). Above 210°F (99°C), reduced differential pressure operating parameters apply.

4.22 CIRCULATING FLUIDS INTRODUCTION SPERRY DRILL motors can operate on most types of circulating fluids, (which may have differing viscosities and densities) including: • Fresh and salt water-based fluids • Oil-based fluids • Oil emulsion SPERRY DRILL motors operate on circulating fluids ranging from air (with surfactant) to muds of 20 ppg (2.40 Sg or 2.40 Kg/l or 1.038 psi/ft).

Since the motor is dependent on the circulating fluid for its operation, all aspects of the circulating fluid should be considered with respect to motor operation efficiency and longevity. Circulating fluid considerations with respect to motors include: • • • • • •

Base waters or oils and primary chemicals and solids. Additive chemicals, solids and gases (e.g. nitrogen). Recirculated cuttings solids. Temperature and pressure effects. Fluids, gases, solids introduced from the formation. Gas introduced during surface operations (aeration).

The points of consideration detailed above relate to motor wear characteristics, and potential for component damage through erosion and abrasion by solids, metallic corrosion by circulating fluid or produced fluid chemicals, and possible elastomer degradation by circulating fluid or produced fluid chemicals.

Circulating fluid sand content should be maintained at less than 2%. Solids content should be minimized for given applications.

4.22.1 WATER-BASED MUDS There are various water-based mud types, including: Calcium Muds, e.g. Lime and Gypsum muds - used to inhibit swelling in dispersive and reactive clays and shales.

4.22.2 OIL-BASED MUDS

KCl/Polymer muds - used where there may be swelling shale and the chance of permeability damage of production zones.

In almost all oil-based muds, oil is the continuous phase and water is the dispersed phase. These muds are commonly termed “invert emulsions.”

Salt Saturated Muds - suitable for drilling salt domes and salt sections. Can be used with polymers to inhibit swelling of bentonite shales.

The oil phase may be weathered crude, diesel or highly refined mineral oils. The water phase may range from fresh to near saturated salt water.

Fresh Water-Based Muds - used when drilling nonreactive or compacted formations.

Most oil muds use a calcium/sodium/magnesium fatty acid soap as the primary emulsifiers.

Native Muds - produced by pumping water downhole where it reacts with formation clays. These muds typically have high solids content and thick filter cake.

Water and treated bentonite clay provide gel strength and barite suspension properties; soaps provide emulsion stability; asphalt may be used to raise the viscosity and for filtration control.

Lignosulfonate Muds - used for muds where high drilled solids contamination and low filter loss is required. In water-based muds, water is the continuous phase. Swelling clays such as bentonite or non-swelling clays such as attapulgite (salt gel) are added to provide viscosity and suspension properties. Inert solids such as barite, and marble or limestone (calcium carbonate), are added to provide mud weight. Chemical additives are added to the mud to control various properties such as viscosity, yield point, gel strength, fluid loss and to control corrosion.

254

The type and quantity of chemical additives and the size, quantity and abrasiveness of inert solids must be considered with respect to potential SPERRY DRILL motor component abrasion, corrosion or elastomer degradation.

Oil-based muds are far more thermally stable than water-based muds making them less susceptible to rheology fluctuations at high temperatures, however they may thin appreciably when heated, resulting in a steady pressure drop after a trip as the circulating fluid temperature increases. Oil-based muds normally provide less of a motor component corrosion problem than water-based muds. However, elastomer degradation can occur due to chemical interactions between elastomer compounds and chemical constituents of the oil-based fluid. For oil-based mud system temperature considerations 255

However, elastomer degradation can occur due to chemical interactions between elastomer compounds and chemical constituents of the oil-based fluid. For oil-based mud system temperature considerations 255

with respect to motor elastomer components, see section 4.21. Oil-based muds provide for higher lubricity than waterbased muds, and provide for higher protection against borehole instability. This means less wear on moving components, especially bearings, as well as for less stress on threaded connections and other components due to tight hole, high drag, high rotary torque etc.

4.22.3 POLYMER MUDS While clay systems impart essential rheological and filtration properties to circulating fluids, clay systems may cause high solids content, high viscosity and high gel strengths. High gel strengths can cause surge and swab problems while high solids content may cause a reduction in drilling rate. High solids content muds also have high pressure losses, which can result in less hydraulic horsepower for the bit nozzles and SPERRY DRILL motor. Polymers may be added to water-based muds, and may be used to produce clay-free polymer systems where solids content is maintained at low levels, which is beneficial to SPERRY DRILL motors. The main advantages of polymer systems is that they can impart adequate viscosity and barite suspension with minimum solids content. Most polymers have good compatibility with other water-based fluids and chemicals and many are relatively insensitive to salt contamination. Polymer systems have been developed with properties which inhibit sensitive shales, reduce fluid loss to permeable formations, enhance hole cleaning and increase 256

ROP. Polymers may be naturally sourced (organic/inorganic) or may be synthetic. Some systems can operate in downhole temperatures in excess of 300°F. Many polymer fluids have friction reducing properties which result in lower system pressure drops than found with clay-based drilling fluids. The friction reducing properties and minimum solids content may result in lower No Load motor pressures. The use of polymers in a water-based circulating fluid must be considered, since SPERRY DRILL motor operating differential pressures may fluctuate or alter due to the polymer friction reducing effect on the rotor and stator power unit. The use of mud lubricants or thinners may also cause reduced motor operating differential pressures.

4.22.4 NEW MUD SYSTEMS ESTER, ETHER AND ALTERNATIVE INVERT EMULSION SYSTEMS These are near biodegradable, environmentally acceptable alternatives to conventional mineral oil-based invert emulsion systems (oil-based muds). These systems are designed in almost exactly the same manner as the conventional OBMs, the main difference being the replacement of the base oil with ester, ether, or other alternative fluids. Ester systems are temperature stable to 300°F, while ether systems are used for higher temperatures. These alternative based fluids contain no hydrocarbon aromatic compounds. Tests show that some elastomers are not compatible with these new fluids and it is recommended that all motor elastomers are tested in the new base fluids prior to use.

motors have been tested and used in various new mud systems. Baroid’s PETROFREE drilling mud is an ester-based invert emulsion system upon which SPERRY DRILL motors have been run extensively. PETROFREE mud is formulated with a vegetable-based ester as the continuous or external phase, very safe to handle and fully biodegradable. PETROFREE was the first true pseudo oil-based mud (POBM), and remains the market leader with respect to the advantageously low kinematic viscosity and density of the base ester. These properties allow the system to be run with low plastic viscosity and more readily controllable equivalent circulating densities.

258

Silicate muds replace inverts in some applications, these muds are low solids polymer systems formulated in seawater or monovalent brines with the addition of a soluble silicate complex for inhibition. Inhibition is achieved through the silicate fluid rapidly sealing or partially sealing the pore spaces. A silicate skin or pressure barrier forms which allows mud hydrostatic pressure to support the borehole wall in a similar manner to an invert emulsion mud. GLYCOL ENHANCED SYSTEMS SPERRY DRILL motors operate effectively with Glycol-enhanced water-based mud systems (GEM). These mud systems offer the following advantages:

SPERRY DRILL motors are regularly run on Baroid’s XP-07. This Synthetic Base Mud (SBM) is a high performance, environmentally-responsible invert emulsion system with low toxicity and enhanced biodegradability.

• • • •

The system is based on a normal alkane continuous phase with a very low kinematic viscosity endowing the XP-07 system with low plastic viscosity and enhanced hole-cleaning characteristics.

Destabilization of shales leading to borehole breakout, caused by filtrate or mud pressure penetration, is reduced when using a glycol-enhanced mud.

XP-07 SBM is well proven in high temperature applications providing low ECD and extremely stable mud properties.

Physical properties - torque, drag, motor pressure drops, etc. with the new alternative systems are normally similar to those experienced with conventional OBMs.

4.22.5 CIRCULATING FLUID MAINTENANCE

Baroid’s BARASILC Silicate Drilling Fluids have been used with SPERRY DRILL motors where their very good shale stabilizing properties are employed to maintain in-gauge hole and discrete cuttings while drilling chalk and reactive shales.

Various ongoing maintenance or conditioning procedures are undertaken to ensure the integrity of a circulating fluid system. Lack of maintenance may cause formation instability, hydraulic inefficiencies and drillstring/BHA component problems.

Enhanced shale inhibition and reduced dilution rates Improved filter cake quality and reduced fluid loss Improved lubricity Enhanced temperature capabilities

GLYCOL ENHANCED SYSTEMS SPERRY DRILL motors operate effectively with Glycol-enhanced water-based mud systems (GEM). These mud systems offer the following advantages:

SPERRY DRILL motors are regularly run on Baroid’s XP-07. This Synthetic Base Mud (SBM) is a high performance, environmentally-responsible invert emulsion system with low toxicity and enhanced biodegradability.

• • • •

The system is based on a normal alkane continuous phase with a very low kinematic viscosity endowing the XP-07 system with low plastic viscosity and enhanced hole-cleaning characteristics.

Destabilization of shales leading to borehole breakout, caused by filtrate or mud pressure penetration, is reduced when using a glycol-enhanced mud.

XP-07 SBM is well proven in high temperature applications providing low ECD and extremely stable mud properties.

Physical properties - torque, drag, motor pressure drops, etc. with the new alternative systems are normally similar to those experienced with conventional OBMs.

4.22.5 CIRCULATING FLUID MAINTENANCE

Baroid’s BARASILC Silicate Drilling Fluids have been used with SPERRY DRILL motors where their very good shale stabilizing properties are employed to maintain in-gauge hole and discrete cuttings while drilling chalk and reactive shales.

Various ongoing maintenance or conditioning procedures are undertaken to ensure the integrity of a circulating fluid system. Lack of maintenance may cause formation instability, hydraulic inefficiencies and drillstring/BHA component problems.

Enhanced shale inhibition and reduced dilution rates Improved filter cake quality and reduced fluid loss Improved lubricity Enhanced temperature capabilities

Additives are required due to changes in mud characteristics during drilling (formation fluids and solids, temperature etc.) or due to changes in mud requirements as depths and formations change. The maintenance or conditioning procedures are undertaken at surface through mechanical means such as solids control equipment or by the addition of chemicals and solids. The chemical constituents, quantities of fluid additives and the chemical constituents, geometry and abrasiveness of solids additives (and mix consistencies) must be considered with respect to SPERRY DRILL motors. Chemical constituents of fluid or solid additives may potentially cause corrosion to metallic components or affect elastomer and sealing components. The geometry and concentration of added solids may cause fluctuations in rotor and stator friction resulting in No Load and differential pressure fluctuations. Should mud treatment materials not be mixed correctly, there is potential for motor component damage or motor plugging. The abrasiveness of added solids may cause accelerated wear of motor components. Circulating fluid sand content should be maintained at less than 2% during motor operations. Solids content should be minimized for the particular operation.

4.22.6 CIRCULATING FLUID PROBLEMS During drilling operations, the characteristics of the circulating fluid may change due to influxes of formation solids, chemicals or gases, circulation fluid losses, or to adverse formation reactions and drillstring problems. Mechanical equipment may be used at surface, or chemicals and solids may be used to modify the circulating fluid as required. The chemical constituents and quantities, reactions and end products of fluid additives and the chemical constituents, geometry and abrasiveness of solids additives (and mix consistencies) must be considered with respect to SPERRY DRILL motors. Details of common circulating fluid problems are supplied to provide a basic appreciation of the dynamic nature of a circulating fluid system, and the effects that contaminants of remedial operations can have with respect to SPERRY DRILL motors. The following list details the contaminants commonly encountered in drilling fluids: • Formation solids. • Soluble salts, including cement (e.g. sodium chloride, calcium sulfate etc.). • Acid gases (e.g. hydrogen sulfide and carbon dioxide) while these contaminants are found in both waterand oil-based muds they do not normally present a serious fluid system handling problem. Soluble salt and acid gas contaminants can cause SPERRY DRILL motor component corrosion and degradation while increased solids in drilling fluids can increase motor component wear rates.

• Clays, shales, sands and unconsolidated formations increase the solids content of the fluid due to mechanical interaction of the drillstring/BHA with the hole walls. Shales and claystones may hydrate, swell and erode especially in water-based muds. This can cause a rapid increase in mud solids content and mud viscosity. Such problems can result in excessive pump pressures, lost circulation of fluid, high levels of torque and drag of the drillstring, packing off and increased fluid loss, in addition to motor problems. Of special concern is the sand content of the mud. Sand is highly abrasive. High mud sand content will greatly accelerate motor component wear. • Soluble salts act on some water-based mud solids in a manner that causes the fluid to thicken and water loss to increase. This can act with high solids content to promote motor component wear. Soluble salts may cause a reduction in circulating pH and a tendency for the mud to trap oxygen which increases motor component corrosion. The most common sources of soluble salts are salt water flows (widely varying salt types and concentrations), sub-surface stringer/salt beds (usually sodium chloride) anhydrite and gypsum (forms of calcium sulfate). Caustic Soda is typically used to increase and maintain the pH value of circulating fluids. Cement that is thoroughly set does not normally contaminate oil or water-based circulating fluids; however, partially set cement can contaminate water-based mud. Unset cement contamination can cause an increase in circulating fluid calcium and pH values, requiring the use of dilution and chemical treatment to restore optimum properties. 262

Cement slurries can contaminate circulating fluids. The slurries can have high abrasive solids content which can thicken muds and accelerate motor component wear.

4.22.7 CIRCULATING FLUIDS AT HIGH TEMPERATURES WATER-BASED MUDS (WBM) Some additives may degrade at higher temperatures and some chemical reactions are accelerated. As a result, motor performance can be affected and accelerated corrosion may occur. Elastomers also tend to degrade at a faster rate. OIL-BASED MUDS (OBM) Generally much more stable than WBM with very little internal chemical reaction at increased temperatures. Note: At elevated temperatures, with particular OBMs, mud chemical constituents can interact with elastomer compounds leading to component degradation (see 4.21).

4.23 LOST CIRCULATION Lost circulation remedial procedures and materials must be considered with respect to SPERRY DRILL motor performance and longevity. Lost circulation materials (LCM) must be considered in relation to SPERRY DRILL motors with respect to their geometry, abrasiveness, concentration levels, chemical content and uniformity of mix. It should be noted that MWD tools usually present more limitations than motors do with respect to LCM. 263

It should be noted that MWD tools usually present more limitations than motors do with respect to LCM. 263

No definitive values can be set for LCM in relation to SPERRY DRILL motors. This is because of the many LCM types that are available and because different types of LCM material can be blended together for specific applications. Each application has to be considered individually. Testing with medium nut plug of up to 40 lb/barrel did not cause any SPERRY DRILL motor functioning or plugging problems. SPERRY DRILL motors have operated satisfactorily in the field with oyster shell/mica/calcium carbonate LCM blends of up to 134 lb/barrel. Incorrect mixing or pumping rates of lost circulation materials can result in the plugging of motors, jet nozzles and MWD equipment. Ensure that LCM materials are well mixed and correctly blended. It is recommended that drillpipe filters/screens are used during LCM pumping operations. Fine and medium lost circulation materials like fibres and flakes are commonly used in low density muds for seepage and natural fracture losses. They can cause friction reducing effects which may fluctuate motor operating differential pressures and output torque values. Granular lost circulation materials are commonly used for induced losses in weighted mud systems. The same considerations apply as for fine and medium lost circulation materials. Larger size hard LCM materials can tend to wear motor components and will more readily plug a motor if incorrectly mixed. Contact Sperry-Sun regarding specific applications.

4.24 CORROSION The metallic components of SPERRY DRILL motors are produced from high grade alloy and stainless steels to stringent specifications. Advanced surface coatings are applied to components where necessary. The specifications of motor component metals and surface coatings provide the required mechanical properties and resistance to corrosion. Although corrosion resistance is an integral attribute of motor component materials and surface coatings, consideration should be given to the minimization or avoidance of corrosive agents. These may initially be present in circulating fluids or may be added to circulating fluids during drilling operations in the form of gases, fluids and solids. There are various agents found in circulating fluids which promote different forms of BHA component corrosive attack, including: Oxygen - is the major cause of drillpipe failure and can result in severe corrosive pitting of motor components. Carbon Dioxide - is not as corrosive as oxygen. High concentrations can cause corrosive pitting. Hydrogen Sulfide - can cause severe pitting damage, stress cracking and sudden component failure due to hydrogen embrittlement. Salts (Alkali and Acid) and Organic Acids - can cause moderate to severe corrosion pitting damage (e.g. chloride attack). The rotating nature of motor components, including housings during string rotation operations, causes motor component cyclic loading.

avoided since corrosive effects can enhance adverse rotation effects. Avoidance of corrosive agents also minimizes the possibility of accelerated corrosion attack, cracking or embrittlement of statically stressed motor components. Increased downhole temperature increases corrosion rates while downhole pressure increases can cause entrapped corrosive gases to go into solution in the circulating fluid, increasing its corrosivity. Various additives are used to reduce circulating fluid corrosivity including: • Oxygen and sulfide scavengers • Inhibitor fluids and films • pH maintenance additives. Consideration should be given to possible motor pressure fluctuations due to the addition of corrosion-reducing agents to the circulating fluid during drilling operations. Also consider the possibility of motor component damage resulting directly from corrosion-reducing additives. For example, while caustic soda may be added to circulating fluids to maintain the pH level, some caustic soda concentrations at certain temperatures can promote serious metallic component corrosion attack. Acid gas influx into the mud system can occur at any time. These gases, notably carbon dioxide and hydrogen sulfide, reduce mud pH and greatly accelerate corrosion, especially in water-based muds. Acid gases can cause sudden and severe motor component corrosion attack.

266

High corrosion levels can occur when used motors are inactive at the rigsite or during transit. Static corrosion of motor components can be minimized by draining and flushing the motor clean, utilizing non-petroleum based lubricants. Draining and flushing operations and lubricants application are detailed in section 4.17.

4.25 THRUST BEARING BALANCE The hydraulic energy of the circulating fluid acts upon internal components of the motor (power unit, transmission unit, drive shaft and bearing assembly). While pumping, due to fluid restricting/sealing effects of the internal component geometries, pressure differentials are created which result in a hydraulic thrust which is directed down through the motor’s internal components to the bit. On large diameter motors where the rotor and flow restrictor areas are large, the magnitude of the pump force often exceeds the anticipated WOB. In high bit pressure drop applications, the same large forces are also generated and must be taken into consideration for off-bottom loading. The application of WOB produces a mechanical thrust which is directed from the bit up through the motor internal components. Any imbalance between the hydraulic downthrust and mechanical upthrust is supported by the thrust bearing assembly and transmitted to the motor housings. To obtain maximum power transmission efficiency and thrust bearing life, hydraulic downthrust loads should be balanced against the mechanical upthrust load. SPERRY DRILL motors can be configured in the workshop for specific drilling objectives: WOB loadings, bit

A.1 CONVENTIONAL DIRECTIONAL DRILLING

Bent Sub

In conventional directional drilling, a motor is designed to be used in the oriented mode only. Deflection is achieved by use of a bent sub above a straight motor or by use of an integral fixed or adjustable bent housing. There are no stabilizers either on the motor or in the drillstring above the motor. A protective sleeve is utilized as all SPERRY DRILL motors are externally threaded to accommodate stabilization. Prior to the introduction of steerable systems, most kickoffs were achieved using this method. The motor/bent sub or bent housing motor would be used to kick-off and build to 15° to 20°, the build to maximum angle being achieved with a rotary assembly. Alternatively, the motor would be used in the oriented mode to build to maximum angle when it would be replaced with a rotary holding assembly.

Rotation of a motor/bent sub or bent housing motor in a directional well will cause inclination to drop sharply, as there is no stabilizer on the motor to act as a fulcrum for the bit. However, below 15° the pendulum force on the bit is low enough to allow the assembly to be rotated to control the build rate, thus creating a basic steerable system. This method is still used to kick-off/nudge particularly in large diameter holes (22" to 26"). Other applications of this method are for sidetracking and correction runs. Care must be taken to ensure proper toolface orientation when using the motor/bent sub or bent housing on a correction run. Maximum turn is achieved with the toolface set at 90° right or left of highside, but the lack of stabilization will result in a drop of inclination at these settings. If it is desired to hold angle, then an intermediate toolface position must be found. This can vary from 275

30° left or right of highside in soft formations to 80° in hard formations. Historically a bent sub was utilized far more than a bent housing, the primary reason being that it made economic and logistical sense to provide a selection of bent subs with a straight motor as opposed to a selection of fixed housing motors that could not be reconfigured at the rigsite. All SPERRY DRILL motors can be supplied with adjustable bent housings obsoleting the requirement for bent subs in most applications. Using a bent housing rather than a bent sub places the bend nearer to the bit. This reduces the bit offset, creating a higher dogleg severity rating for a given size bend. A bent housing is generally more effective than a bent sub when the annular clearance between the motor and borehole is low (hole diameter is less than twice the motor diameter). Bent subs have proven to be more effective in large hole sizes (22" to 26"), especially when initiating the kick-off. Bent housing motors are generally easier to orient, particularly in higher hole curvatures.

The essential requirement of a steerable system is that it can be used to drill in both oriented and rotary modes. This system consists of a SPERRY DRILL motor configured with either a fixed or adjustable bent housing, and a stabilizer on the bearing housing. To enhance the sliding capability of the motor, the stabilizers have wide, straight blades tapered at either end and are undergauge relative to hole size (typically 1/8" to 1/4"). Depending on the application, additional stabilizers may be used above the motor. Although these stabilizers are generally spiral, the blades should be tapered and undergauge. Using a SPERRY DRILL motor or steerable system yields distinct advantages (resulting in lower drilling costs) compared to conventional directional drilling: • An average planned build rate can be adhered to by a combination of orienting and rotating. • After completing the build-up, the assembly can be rotated ahead to hold angle with minor corrections to inclination and azimuth being made by orienting as necessary. • Extended intervals can be drilled through different formations without tripping for assembly changes. • By having the capability to correct the wellbore course at any time, tortuosity is minimized which reduces torque and drag. • Drilling performance is maximized by efficiently delivering the torque and horsepower at the bit. Overall design of the steerable assembly will depend upon the application, and the important considerations are listed next.

278

• The expected build rate in oriented mode should be slightly greater [typically 1 to 2°/100’ (30m)] than required so as to guarantee the build rate. If the actual build rate be greater than required, a combination of oriented and rotary drilling is used, with some restrictions that are discussed later in this section. • The number of stabilizers used should be kept to a minimum to reduce drag in the oriented mode. • For a long build-up section (i.e. low build rate) it may be advantageous to configure the assembly to build in the rotary mode. As the build rate in rotary mode would generally be less than that required (especially at lower inclinations), short orientations would be needed to ensure the average required build rate is achieved. This specific application would apply where the end of the build section coincides with casing point, or where ROP in rotary mode is significantly more than in oriented mode. • For extended interval drilling in which orientation is anticipated for only short course corrections, the motor bend should be kept as small as practical to reduce dogleg severity over the oriented section and minimize bending stresses in the motor while rotating. An exception to this would be when high frictional forces (e.g. in a long horizontal section) severely reduce ROP in the oriented mode. In this case a greater bend will enable corrections to be effected over a shorter distance. • Any tubular/connection lying in a curved hole is subjected to a bending stress. If the drillstring is rotated, the tubular/connection is subjected to cyclical stresses. If the stress is above the endurance limit for the steel type, then a finite number of stress reversals (cycles) will result in a fatigue failure (See 4.13 & 279

As is generally accepted, medium radius refers to build rates between 6° to 15°/100 Ft (30m). The vast majority of medium radius drilling is undertaken in hole sizes of 12-1/4" and under, using motors of 8" diameter and less (8" motors are twice as flexible as the 9-5/8").

A.5 PERFORMANCE DRILLING By using a motor in place of a rotary assembly, the rate of penetration can be significantly enhanced as the higher RPM provides increased mechanical horsepower at the bit. The proven reliability of SPERRY DRILL motors coupled with the wide range of power sections available makes them ideally suited for the performance/extended interval drilling in both vertical and deviated holes. In vertical wells when the steerable option is not required, the SPERRY DRILL motor stabilizer should be between full gauge to 1/16" undergauge to better centralize the bit. Fixed or Adjustable Bent Housing

Straight Motor

For performance drilling in the tangent sections of deviated wells, it makes sense to maintain steerability by having a low angle adjustable or fixed housing and standard SPERRY DRILL motor stabilizer (typically 1/8" to 1/4" undergauge) to aid sliding should course corrections be required. The best performance will be achieved by matching the bit (PDC, diamond, or rockbit) with the formation(s) and selecting the proper SPERRY DRILL motor for the bit in terms of torque, RPM, and horsepower.

A.6 HORIZONTAL DRILLING

Horizontal drilling is one of the major applications of steerable systems. Downhole motors are fundamental to the success of horizontal drilling by enabling the well to be steered to horizontal at the required location with the required azimuth.

Horizontal drilling is one of the major applications of steerable systems. Downhole motors are fundamental to the success of horizontal drilling by enabling the well to be steered to horizontal at the required location with the required azimuth.

287

Steerable motors are used in rotary mode to drill the horizontal section with orientations being made as required to keep the well on course. If the build-up to horizontal was medium radius, the motor would be reconfigured to provide a lower dogleg severity for orientations made in the horizontal section (see A.2).

A.7 HOLE OPENING High torque SPERRY DRILL motors provide operational flexibility when performing hole enlargement operations with large diameter aggressive hole openers. SPERRY DRILL motors can be used to drive hole openers with pilot drill bits. Use of SPERRY DRILL motors provides the option of not having to rotate the drillstring. Drillstring rotation may be used to achieve improved performance and better hole cleaning. Should high flow rates be required for efficient hole cleaning, multi-lobe motors of 3-1/8" diameter and larger can be configured with rotor jet nozzles.

A.8 HOLE SPUDDING SPERRY DRILL motors can be used in offshore spudding operations allowing the drillstring to remain stationary. This can be of major benefit when spudding in deep water/high current locations. Drillstring rotation can be used to optimize drilling performance. High torque, low speed SPERRY DRILL motors allow large diameter offshore spudding operations to commence at low flow rates thus minimizing the possibility of bore hole wall and sea bed erosion damage. 288

The use of jetted rotors permits high fluid flow rates as required for efficient hole cleaning. Flow rates of up to 2000 gpm can be used with a correctly nozzled 11-1/4" diameter motor. The high motor output torque allows controlled drilling operations to proceed with relatively low WOB. Controlled drilling operations and subsequent reaming operations minimize tendencies for the hole to deviate from vertical.

A.9 CONDUCTOR PIPE DRILL DOWN During spudding operations or between spudding and setting conductor pipe, problems due to hole wall collapse or string/formation contact can hamper conductor pipe running. For this reason the hole may be drilled and pipe run simultaneously by using a SPERRY DRILL motor and an underreamer fitted with a pilot bit. When the desired depth has been reached the underreamer arms can be retracted and the drilling assembly removed from the conductor pipe. Since there is no rotation of the drillstring in the conductor pipe, wear is avoided and a high level of torque is ensured at the underreamer/bit. If required for hole hydraulics, rotor jet nozzles can be used to extend the operating flow range of the motors.

A.10 UNDERREAMING AND CASING CUTTING SPERRY DRILL motors can be used to provide controlled high torque and rotation to hydraulically activat289

Steerable motors are used in rotary mode to drill the horizontal section with orientations being made as required to keep the well on course.

A.11 MILLING APPLICATIONS The high torque output of SPERRY DRILL low speed motors permits their use in various applications, from milling cement to milling metal, including the milling of casing windows and complete casing sections. The output torque range of the motors provides for operating flexibility when milling hard materials with aggressive mills.

If required, 3-1/8" to 4-3/4" diameter multi-lobe motors can be configured with rotor jet nozzles to provide high flow rates for optimum hole hydraulics.

A.13 CORING APPLICATIONS High torque, low speed SPERRY DRILL motors can be used during coring operations to drive core barrels of various lengths and liner types and with all types of stabilizers and core heads.

• Long, Medium and Short Radius Drilling in existing wells for workover operations, re-entries, or new development drilling.

Motor coring can be performed in both vertical and highly inclined holes. Use of motors for coring eliminates the need for drillstring rotation which reduces core barrel vibration and shock loading. This ensures the integrity of recovered cores in most formations. The wide variety of power sections allows the motor to be selected to provide optimum torque and rotational speed to the core head.

• Surface and subsurface mining applications.

A.14 AIR, GAS AND FOAM DRILLING

The relatively short length of the small motors (1-3/4" to 4-3/4" diameters) make them suitable for applications on slim-hole drillpipe or coiled tubing in workover applications such as scale, sand or cement milling and casing or tubing cutting.

Multiphase, air or nitrogen drilling with motors requires that careful attention is paid to all operating parameters during both the planning and drilling operations. Since air and nitrogen are compressible, the air or nitrogen contained in the circulating fluid changes volume with fluctuating pressures as it passes through the motor. Motor differential operating pressures should be maintained as constant as possible to minimize the fluctuating loading of motor components and the bit. The compressibility of air and nitrogen causes a time delay between actual motor operating pressure fluctuations and standpipe fluctuations observed at surface. Unlike with mud, motor stalls with air, nitrogen or multiphase fluids are not easily identified because of the time delay in observing corresponding standpipe pressure increases. Motor stalls are best identified by significant reductions in ROP. Motors run on air, nitrogen or multiphase fluids are more sensitive to WOB changes than when they are run on mud. Motors should be started gradually with light WOB applied. All efforts should be made to avoid running the motor freely off bottom. As operating pressure increases, weight can gradually be added to the bit to attain optimum ROP. If motors are allowed to run freely off bottom when operating on air or multiphase fluids, a runaway situation may occur where the motor RPM will instantaneously rise above design limits causing severe vibration and internal damage. The standpipe pressure should always be bled off before picking the motor up off bot-

During air or nitrogen drilling it is essential that a lubricant is added to form a mist which provides lubrication to the dynamic load bearing surfaces in the motors. Contact your Sperry-Sun representative for additional information regarding air, nitrogen and multiphase motor drilling.

A.15 UNDERBALANCED DRILLING The technique of drilling with the majority of the circulating system volume being nitrogen or air and the system pressure being less than that of the formation pressure, is referred to as Underbalance Drilling. Many drilling and production benefits have been realized through the use of this drilling technique. Since SPERRY DRILL motors can operate on a variety of circulating fluid types from straight fluids to multiphase fluids and air or nitrogen, they can readily be used in Underbalance Drilling programs. Drilling underbalance requires close control of operating parameters. Underbalance Drilling System components and techniques vary depending on the percentage of nitrogen or air present in the circulating system. Modifications to standard motors may be required. The real-time monitoring of downhole pressure can be achieved using Sperry-Sun s PWD (Pressure-WhileDrilling) tools, this provides for accurate control of the amount of nitrogen or air within the circulating system.

MOTOR RELIABILITY, QUALITY AND SUPPORT SYSTEMS

SPERRY DRILL motors are manufactured, repaired and maintained in accordance with written procedures which are contained in a number of documented systems. The SPERRY DRILL motor product line support systems interact to ensure the highest quality of materials, dimensional accuracy, condition evaluation and assembly methods. RELIABILITY SPERRY DRILL motor reliability is monitored by a Product Support System. This software-based system provides for: the rigsite reporting of perceived motor problem reports, efficient analysis of reported problems, and effective reporting to customers. All recorded motor problems are fully addressed and verified. Where a problem with a SPERRY DRILL motor has occurred, the Product Support System provides the means to correctly categorize the problem type. Correct categorization of types allows for individual or cluster problems to be efficiently addressed. Various problem categories exist, these include motor design, manufacture, repair and maintenance, directional driller applied operational parameters, customer requested operational parameters, excessive downhole conditions, other BHA tooling malfunctioning and foreign objects in the circulating system. The Product Support System produces guideline statistical data regarding the Mean Time Between Service Interrupt (MTBSI) time values for motors. MTBSI val296

ues are produced for a given time period and location by relating the cumulative run hours for a motor type to the number of service interrupts attributable directly to malfunctions, but not misuse, unforeseen circumstances, foreign object passage etc, with that motor type. The assignment of specific maximum cumulative operating hours on motor components is not possible due to the many varying downhole parameters which act individually and cumulatively upon motor components. The motor components themselves have varying chemical compositions and physical attributes, each can react differently when acted upon by the same individual or cumulative downhole parameters. Detailed inspection procedures, industry standard and specialist inspection equipment and empirical company guidelines, gained through years of experience, ensure that the optimum balance is maintained between motor component longevity and reliability. QUALITY ASSURANCE SYSTEM Motor quality assurance is maintained at acceptable levels through adherence to the procedures laid forth in the Sperry-Sun Quality Assurance Manual and by the interaction of the various SPERRY DRILL motor support systems and support group personnel. SPERRY DRILL motor Quality Assurance relates to all manufacturing and repair and maintenance procedures and offers traceability from original material milling and compounding through manufacturing processes, to new and used component fit for use inspection criteria (Also see B.7).

The assignment of specific maximum cumulative operating hours on motor components is not possible due to the many varying downhole parameters which act individually and cumulatively upon motor components. The motor components themselves have varying chemical compositions and physical attributes, each can react differently when acted upon by the same individual or cumulative downhole parameters. Detailed inspection procedures, industry standard and specialist inspection equipment and empirical company guidelines, gained through years of experience, ensure that the optimum balance is maintained between motor component longevity and reliability. QUALITY ASSURANCE SYSTEM Motor quality assurance is maintained at acceptable levels through adherence to the procedures laid forth in the Sperry-Sun Quality Assurance Manual and by the interaction of the various SPERRY DRILL motor support systems and support group personnel. SPERRY DRILL motor Quality Assurance relates to all manufacturing and repair and maintenance procedures and offers traceability from original material milling and compounding through manufacturing processes, to new and used component fit for use inspection criteria (Also see B.7).

REPAIR AND MAINTENANCE SYSTEM

B.2 GENERAL OPERATING PRINCIPLES

Motor repair and maintenance relates to the procedures laid forth in the documented SPERRY DRILL motor Repair & Maintenance System. The repair & Maintenance System is adhered to by all workshop technicians and product line engineering personnel. The system provides the necessary data to correctly undertake and record motor assemblies and disassemblies.

SPERRY DRILL motors operate on the reverse application of the Moineau pump principle. Pressurized circulating fluid is pumped into a progressing axial cavity formed between a helical-lobed metallic rotor and a helical-lobed elastomeric stator.

METROLOGY SYSTEM — See B.4 RESEARCH & DEVELOPMENT New and more advanced component designs and materials are constantly being tested and evaluated in order to increase the downhole working envelope, reliability and longevity of motor components (See 3.1).

The force of the pressurized circulating fluid pumped into the cavity between the rotor and the stator causes the rotor to turn inside the stator. The action of the rotor and stator converts the hydraulic energy of the circulating fluid to mechanical energy (rotation) which is transferred to the drill bit. Modification of lobe numbers and geometry at the design stage provides for variation of motor input and output characteristics to accommodate different drilling operations requirements. SPERRY DRILL motors are available in various outer diameters from 1-3/4" to 11-1/4" with a range of operational input/output characteristics.

SPERRY DRILL Motor Dump Sub

B.3 SPERRY DRILL MOTOR DUMP SUB The geometry of the rotor/stator power unit restricts fluid flow between the drillstring and annulus during tripping operations. A dump sub can be incorporated above the power unit in the motor assembly to allow the drillstring to fill when tripping in the hole and empty when tripping out of hole. The dump sub also permits low flow rate circulation if required.

Piston

Spring

The dump sub contains a valve which is ported to allow fluid flow between the drillstring and annulus. Motors can be run with no dump sub if the circulating fluid solids content is high and of concern with respect to valve fouling or in air drilling applications. The dump sub is a sliding piston and spring design. All parts are manufactured from high quality steels. The design uses a series of precision seals and machined/ coated surfaces to ensure efficiency and reliability.

Fluid Ports

The valve remains open until the action of the pressurized circulating fluid on the piston overcomes the spring stiffness which causes the piston to move, closing the ports to the annulus. All fluid then passes through the power unit. When circulation is stopped the spring force moves the piston back to its original position and opens the ports to the annulus. The ports are fitted with filters to avoid valve fouling by solids in the circulating fluid. Figure B.3 (1)

* The use of rotors with bypass jet nozzles allows circulating fluid flow to and from the drillstring and hole annulus. Therefore, a dump sub is not essential to avoid the pulling of wet strings, providing the nozzle size is large enough to allow sufficient fluid flow.

The flow rate required to close the valve is lower than the minimum specified working flow rate of the motor. Dump subs are available on all motor sizes. The dump subs have API and common drilling industry connections top and bottom allowing the motor to be readily 301

operated with the dump sub in position or removed. A bent sub may be positioned between the dump sub and the power unit which reduces the bit to bend length, increasing the bend effect on the bit.

B.4 SPERRY DRILL MOTOR POWER UNIT (ROTOR/STATOR) SPERRY DRILL motor power generation derives from the Moineau pump principle. In the motor design, a rotor/stator pair convert the hydraulic energy of the pressurized circulating fluid to the mechanical energy of a rotating shaft.

Rotor (Steel)

A feature of the power unit design is that it can accommodate various circulating fluids, including oil-based muds, water-based muds, water, air and foam while producing the output characteristics required to achieve successful drilling operation. Stator (Elastomer)

The rotor and stator are of lobed design. Both rotor and stator lobe profiles are similar, with the steel rotor having one less lobe than the elastomeric stator. Power units may be categorized with respect to the number of lobes and effective stages. The rotor and stator lobes are helical in nature with one stage equating to the linear distance of a full wrap of the stator helix.

Stator Housing (Steel)

The difference between the number of lobes on the rotor and the number of lobes in the stator results in an eccentricity between the axis of rotation of the rotor and the axis of the stator.

The rotor/stator lobes and helix angles are designed so that the rotor/stator pair seal at discrete intervals. This 303

results in the creation of axial fluid chambers or cavities which are filled by the pressurized circulating fluid. The action of the pressurized circulating fluid causes the rotor to rotate and precess within the stator. The lobe geometry and amount of eccentric rotor movement is designed to minimize contact pressure, sliding friction, abrasion and vibration thus reducing rotor and stator wear. The elastomeric stator is injection moulded with detailed attention given to elastomer composition consistency, bond integrity and lobe profile accuracy. The stator is molded directly to the power unit housing. The number of stator lobes varies from 2 to 10 across the motor range. The metallic rotor is precision machined to close axial and radial tolerances and can be coated to maximize wear and corrosion resistance. The rotors of all multilobe motors 3-1/8" diameter and larger may be fitted with bypass jet nozzles to extend the motor operating flow range (see 4.6). The number of rotor lobes varies from 1 to 9 across the motor range. Motor input and output power characteristics can generally be considered to be a function of the number of lobes, lobe geometry, helix angle and number of effective stages. Within the specified motor operating ranges, bit rotation speed is directly proportional to the circulating fluid flow rate between the rotor and stator. Above the maximum specified operating differential pressure, fluid leakage occurs between the rotor and stator seals and bit rotation speed reduces. Excessive fluid leakage results in no rotation of the bit due to the rotor becoming stationary, or stalling, in the stator. 304

Similarly, within the specified motor operating ranges, motor output torque is directly proportional to the differential pressure developed across the rotor and stator. If the motor is operated above the maximum specified torque production values, there can be a tendency for accelerated rotor/stator wear and stalling. The power developed by the rotor and stator is directly proportional to both rotational speed and torque. Motor horsepower and related values of rotational speed and torque should be fully considered with respect to individual drilling applications. The rotor and stator designs take account of the various downhole operating parameters which may be present during downhole drilling applications, including the effects of circulating fluid weight/viscosity, temperature, solids content, and lost circulation materials content. Chemical constituents of formation fluids and gases are also given detailed consideration with respect to stator elastomers. Development of the motor base materials and coatings continues in order to offer maximum resistance against thermal effects, erosion, corrosion and abrasion. The SPERRY DRILL motor Metrology System is a proceduralized system which employs special measurement tools to accurately measure rotors and stators. The rotors and stators are carefully sized and matched to provide the optimum mating fit for planned downhole operating conditions. This avoids start-up problems, ensures acceptable output power characteristics and maximizes rotor and stator reliability and longevity.

maximum operating pressure for a number of stages for a particular model, equates to the specified maximum motor operating pressure for that power unit model. The maximum operating pressure per stage is selected to optimize stator elastomer loading. High downhole operating temperatures can affect the mating fit between the rotor and stator, resulting in increased loading of the stator elastomer. Rotor/stator mating fits (standard fit, oversize fit, double oversize fit, etc.) and geometries are selected to accommodate downhole operating temperatures. Motors configured for operations at high temperatures are referred to as temperature compensated motors. Modified motor operating pressures and special operations procedures are recommended in high temperature conditions. See 1.7 and 4.21.

A variety of constant velocity transmission unit designs are employed, providing maximum transmission efficiency for differing rotor/stators.

Transmission units are of both multi-element and onepiece designs. The multi-element design consist of a central shaft connected at either end with universal couplings.

RADIAL BEARINGS Metallic and non-metallic radial bearings are employed above and below the thrust bearings to absorb lateral side loading of the drive shaft. Side loading of the drive shaft can be significant in steerable and correction run applications. The radial bearing materials are selected and manufactured to provide reliable operation in all drilling environments. FLOW RESTRICTORS The bearing assembly is cooled and lubricated by approximately 5 to 8% of the circulating fluid; the fluid flow is regulated by a precision machined flow restrictor device. Two types of flow restrictors are available: • High Pressure flow restrictors provide for 200 to 1200 psi bit pressure drops. • Low Pressure flow restrictors provide for 0 to 350 psi and 0 to 400 psi bit pressure drops. Flow restrictors work in a similar way that jetted rotors do, in that they provide a restricted fluid flow path. In the case of a bearing assembly flow restrictor the flow across it supplies fluid to the bearings for cooling and lubrication, while a jet in a rotor ensures that fluid is bypassed away from the rotor and stator to protect them from overloading and erosion. As with a jet nozzled rotor, the amount of fluid which passes across a bearing assembly restrictor depends on the size of the restricting orifice and the pressure acting across it, in the case of the restrictors the back pressure is that of the pressure drop across the bit.

310

The flow restrictor type used is set in the motor workshop, based on planned bit hydraulics. Flow restrictor characteristics can not be changed at rig site. Radical changes of bit hydraulics from those on which the flow restrictor was selected should be avoided. Running high (500 psi plus) bit pressure drops with low pressure flow restrictors allows too much fluid to pass across the bearings and can wash out the bearings. Running low (300 psi minus) bit pressure drops with high pressure flow restrictors causes too little fluid to pass across the bearings and can result in over heating and wear of the bearings. DRIVE SHAFTS The drive shaft transmits both axial and torsional loading to the bit. The drive shaft is a forged component which is designed such that fatigue strength, axial and torsional strength are maximized. It has a threaded connection at the bottom end to facilitate connection of the drill bit. The drive shaft of the SPERRY DRILL motor is the only external rotating component. Fluid is supplied to the drill bit through the center of the drive shaft. All bearing assemblies are designed such that the drive shaft and bearings can not strip out of the bearing housing if the drillstring becomes stuck and the maximum downhole overpull for a particular motor is exceeded.

As with all other motor components, tubular and adjustable housing component integrity is maintained through the traceability of manufacturing processes:

In addition, the housings must have sufficient stiffness/flexibility to function effectively as part of directional control BHAs and must provide good resistance to fatigue.

gauge manufacturers. Machine shop subcontractors are regularly audited and training is provided where necessary regarding SPERRY DRILL motor custom thread production and maintenance. All new connections are inspected using NDT methods. Tubulars are assembled to specific torque values using regularly calibrated hydraulic torque benches, with API specification thread dope applied to clean corrosion-free connections as necessary. A proceduralized repair and maintenance system and thread inspection manual are adhered to. Used connections are inspected using Non-Destructive Testing (NDT) techniques and re-worked, if necessary by certified subcontractors to standards per original manufacture. Re-worked connections are inspected using dimensional and NDT techniques. The thread roots of used tubular connections are inspected using state of the art Alternating Current Field Measurement (ACFM) equipment which very accurately detects anomalies in a current flow which is induced along the thread roots. This application of ACFM equipment was jointly developed by Sperry-Sun. CONNECTIONS Standard API thread forms typically have sixty degree V form threads with tapers of two or three inches per foot. The tapers are accommodated by the relatively large cross sectional areas (thick walls) of drill collars, pipe etc. The inner and outer diameter constraints which are inherent to motor tubular housings result in housing cross-sectional areas which are relatively small (thin walls) compared to many other drillstring component tubulars. 314

Motor tubular housing geometries require that custom threaded connections are employed. Early custom threads utilized API or ACME thread forms machined on reduced tapers. These connection types are prone to backing-off when acted upon by dynamic mechanical loadings during motor drilling operations. Thread locking compounds can be utilized to avoid the backing-off of these connections. However, the workshop break out of such connections and removal of the thread locking compounds can lead to damage of the connections, some damage types are not easily detected. SPERRY DRILL MOTOR TUBULAR HOUSING CONNECTIONS DEVELOPMENT OVERVIEW The main objectives of the SPERRY DRILL motor tubular housing threaded connection design study were: • To obtain a high make-up torque connection with high stiffness and resistance to bending, shoulder separation and fatigue • To produce a connection with good resistance to downhole back-off and make-up, which did not require the use of thread locking compounds Extensive design modelling and controlled testing led to the development of the current Modified Acme tapered connection for the SPERRY DRILL motor: During the 1970s, oilfield modified Acme connections were employed in a number of non-drilling motor tools. In order to accommodate the motor tubular housing inner and outer diameter constraints, Sperry-Sun modified Acme connections are machined on shallower tapers than the early oilfield modified connections were. 315

These connection types are prone to backing-off when acted upon by dynamic mechanical loadings during motor drilling operations. Thread locking compounds can be utilized to avoid the backing-off of these connections. However, the workshop break out of such connections and removal of the thread locking compounds can lead to damage of the connections, some damage types are not easily detected. SPERRY DRILL MOTOR TUBULAR HOUSING CONNECTIONS DEVELOPMENT OVERVIEW The main objectives of the SPERRY DRILL motor tubular housing threaded connection design study were: • To obtain a high make-up torque connection with high stiffness and resistance to bending, shoulder separation and fatigue • To produce a connection with good resistance to downhole back-off and make-up, which did not require the use of thread locking compounds Extensive design modelling and controlled testing led to the development of the current Modified Acme tapered connection for the SPERRY DRILL motor: During the 1970s, oilfield modified Acme connections were employed in a number of non-drilling motor tools. In order to accommodate the motor tubular housing inner and outer diameter constraints, Sperry-Sun modified Acme connections are machined on shallower tapers than the early oilfield modified connections were. 315

Upon connection make-up the SPERRY DRILL motor modified Acme box and pin threads have a slight interference fit at the thread crests/roots. Each pin crest is in contact with each box root over the full length of engagement.

STABILIZERS

When assembled the radial forces are exerted normal to the taper axis of the connection and are distributed across the entire width of the thread root, the result being lower contact stresses.

• Rig interchangeable offset pads (kick pads)

Sperry-Sun modified Acme connections employ generous thread root radii which effectively reduce stress concentration factors. Compared with a 60 degree Vthread, the modified Acme connection engages closer to the thread root and pulls against the flank which is inclined approximately 5 degrees versus 30 on API connections (US Standard Acme threads have flanks at 141/2 degrees). As a result the modified Acme connection does not experience the stresses at the root exerted by the wedge effect of the API makeup engagement. The enhanced area of contact in the current thread design yields a high torque connection with a tremendous amount of inherent radial support and stiffness, which is ideal for steerable motor drilling applications. SPERRY DRILL motor tubular housing tapered connections do not require thread locking compounds. In non-critical and internal connections, taper modified API forms are employed in the SPERRY DRILL motor. Motor top and bottom tubular housing connections are manufactured to API and other common drilling industry standards to ensure compatibility with drill bits and BHA components.

316

SPERRY DRILL motors can be used in conjunction with various stabilizer types: • Rig interchangeable sleeve stabilizers

Rig Interchangeable sleeve stabilizers and offset pads are designed by Sperry-Sun and provide both stabilization and motor housing protection. The pads are manufactured by subcontractors employing strict QA/QC procedures and certified operators. Design considerations include: • Number of blades • Blade width (annular flow area) • Blade depth • Blade gauge length • Blade profile (e.g. melon) • Front/rear flank angles • Blade angular coverage • Threaded connection type • Body and blade materials • Blade coating materials. Stabilizers and pads designed by Sperry-Sun are manufactured from high grade alloy steel which is heat treated, quenched and tempered to stringent specifications to obtain the same properties as the tubular housings.

317

Blades are of inserted, crushed tungsten carbide and rectangular wear element types held in a tungsten carbide matrix, or of the serrated tungsten insert type. Stabilizer integrity is assured by methods similar to that employed during tubular production, including NDT inspection. Eccentric stabilizers and offset pads can be correctly aligned to bent housings and subs by the Sperry-Sun Supervisor utilizing specially supplied shims. Special application motors for medium and short radius drilling operations employ eccentrically machined bearing housings, the eccentricity being aligned with reference to the attitude of the motor bent housing. Where required for directional control reasons nearbit stabilizers can be supplied for make-up between the bit and motor driveshaft. Note: To ensure effective drilling hydraulics and avoid cuttings fouling and hole washout, the upsets on the motor bearing housings, where the sleeve stabilizers locate, are minimized.
