2.0 MOTOR SELECTION
Computalog Commander™ drilling motors are organizedinto three different selections to provide the broad rangeof bit speeds and torque outputs required to satisfy amultitude of drilling applications. These selectionsinclude:
H - High Speed / Low Torque
M - Medium Speed / Medium Torque
L - Low Speed / High Torque
The H style of Computalog Commander™ drilling motorutilizes a 1:2 lobe power section to produce high speedsand low torque outputs. They are popular choices whendrilling with a diamond bit, tri-cone bit drilling in soft for-mations, and directional applications where single shotorientations are being used.
The M style of Computalog Commander™ drilling motortypically utilizes a 4:5 or 5:6 lobe power section to pro-duce medium speeds and medium torque outputs. Theyare commonly used in conventional directional and hori-zontal wells, in diamond bit and coring applications, aswell as sidetracking.
The L style of Computalog Commander™ drilling motortypically uses a 7:8 lobe power section to produce lowspeeds and high torque outputs. They are used in mostdirectional and horizontal wells, medium to hard forma-tion drilling, and PDC bit drilling applications.
In additions to the above, further specifications arerequired as there are several different drilling motorsavailable in each speed range, designed to produceslightly different speed ranges and torque outputs. Inorder to simplify identification of these different styles ofdrilling motors, a second letter is used, indicating the roleof the drilling motor design. These specifications cur-rently include:
A - Air Drilling Motor - The power section has beenspecifically designed to operate with a compressible gassuch as air or nitrogen, but also operates with imcom-pressible fluids. The specifications in this handbook indi-cate the performance of this design of drilling motor withwater. If information of the performance with a com-pressible fluid is required, please contact your nearestComputalog Ltd. representative.
B - Modified Drilling Motor - The bearing section ofthe drilling motor has been modified from a standarddrilling motor to provide slightly different drilling char-acteristics (ie. change bit to bend distance, etc.)
13985 MOTOR Handbook.QXD 3/12/01 2:59 PM Page 6

E - Extended or Performance Drilling Motor - Thepower section of the extended or performance drillingmotor is longer than the power section of the standarddrilling motor, providing greater torque capacity at a sim-ilar output speed range. Build rate capacity of thesestyles of drilling motors is reduced due to increasedlength of the drilling motor.
N - Standard Drilling Motor / Regular Length - Theseare the original Computalog Commander™ I, II and IIIdrilling motors. These drilling motors have standardlength power sections.
S - Short Radius Drilling Motor - The drilling motorhas been specifically designed to perform drilling of shortradius wellbores. The bearing section of the drillingmotor has a reduced bit to bend length, and the powersection is short to allow higher build rates.

3.0 COMPONENTS
All Computalog Commander™ drilling motors consist offive major assemblies:
1. Dump Sub Assembly,
2. Power Section,
3. Drive Assembly,
4. Adjustable Assembly, and
5. Sealed Bearing Section.
3.1 DUMP SUB ASSEMBLYAs a result of the power section (described below), thedrilling motor will seal off the drill string ID from theannulus. In order to prevent wet trips and pressure prob-lems, a dump sub assembly is utilized. The dump subassembly is a hydraulically actuated valve located at thetop of the drilling motor that allows the drill string to fillwhen running in hole, and drain when tripping out ofhole. When the pumps are engaged, the valve automati-cally closes and directs all drilling fluid flow through themotor.
In the event that the dump sub assembly is not requiredor desired, such as in underbalanced drilling using nitro-gen gas or air, it’s effect can be negated by simply replac-ing the discharge plugs with blank plugs. This allows themotor to be adjusted as necessary, even in the field.Drilling motors 95 mm (3 3/4”) and smaller require thedump sub assembly to be replaced with a special blank sub.
3.2 POWER SECTIONThe Computalog Commander™ drilling motor power sec-tion is an adaptation of the Moineau(1) type positive dis-placement hydraulic pump in a reversed application. Itessentially converts hydraulic power from the drillingfluid into mechanical power to drive the bit.
The power section is comprised of two components; thestator and the rotor. The stator consists of a steel tubethat contains a bonded elastomer insert with a lobed,helical pattern bore through the center. The rotor is alobed, helical steel rod. When the rotor is installed intothe stator, the combination of the helical shapes andlobes form sealed cavities between the two components.When drilling fluid is forced through the power section,the pressure drop across the cavities will cause the rotorto turn inside the stator. This is how the drilling motor ispowered.
It is the pattern of the lobes and the length of the helixthat dictate what output characteristics will be developedby the power section. By the nature of the design, thestator always has one more lobe than the rotor. The illus-trations in Figure 1 show a 1:2 lobe cross-section, a 4:5lobe cross-section and a 7:8 lobe cross-section. Generally,as the lobe ratio is increased, the speed of rotation isdecreased.

13985 MOTOR Handbook.QXD 3/12/01 2:59 PM Page 8

The second control on power section output characteris-tics is length. A stage is defined as a full helical rotationof the lobed stator. Therefore, power sections may beclassified in stages. A four stage power section containsone more full rotation to the stator elastomer, whencompared to a three stage. With more stages, the powersection is capable of greater overall pressure differential,which in turn provides more torque to the rotor.
As mentioned above, these two design characteristics canbe used to control the output characteristics of any sizepower section. This allows for the modular design ofComputalog Commander™ drilling motors making it pos-sible to simply replace power sections when different out-put characteristics are required.
In addition, the variation of dimensions and materials willallow for specialized drilling conditions. With increasedtemperatures, or certain drilling fluids, the stator elas-tomer will expand and form a tighter seal onto the rotorand create more of an interference fit, which may resultin stator elastomer damage. Computalog Commander™drilling motors are available when requested with statorsthat take these conditions into account. This will result inminimal loss in performance for ComputalogCommander™ drilling motors used in these specializedconditions.
3.3 DRIVE ASSEMBLYDue to the design nature of the power section, there is aneccentric rotation of the rotor inside of the stator. Tocompensate for this eccentric motion and convert it to apurely concentric rotation, Computalog Commander™drilling motors utilize a high strength jointed driveassembly. The drive assembly consists of a drive shaft witha sealed and lubricated drive joint located at each end.The drive joints are designed to withstand the high

torque values delivered by the power section while creat-ing minimal stress through the drive assembly compo-nents for extended life and increased reliability. The driveassembly also provides a point in the drive line that willcompensate for the bend in the drilling motor requiredfor directional control.
3.4 ADJUSTABLE ASSEMBLYAll Computalog Commander™ drilling motors are sup-plied with a surface adjustable assembly. The adjustableassembly can be set from zero to three degrees in varyingincrements in the field. This durable design results inwide range of potential build rates used in directional,horizontal and re-entry wells. Also, to minimize the wearto the adjustable components, wear pads are normallylocated directly above and below the adjustable bend.Zero to four degree adjustable assemblies are also avail-able when required.
3.5 SEALED BEARING SECTIONThe bearing section contains the radial and thrust bear-ings and bushings. They transmit the axial and radialloads from the bit to the drill string while providing adrive line that allows the power section to rotate the bit.Computalog Commander™ drilling motors utilize sealed,oil filled, and pressure compensated bearing assembliesto assure extended, reliable operation with minimalwear. As no drilling fluid is used to lubricate the drillingmotor bearings, all fluid can be directed to the bit formaximized hydraulic efficiency. This provides forimproved bottom-hole cleaning, resulting in increasedpenetration rates and longer bit life.
3.6 KICK PADSAll Computalog Commander™ drilling motors incorpo-rate wear pads directly above and below the adjustablebend for improved wear resistance. Eccentric kick padscan also be used on Computalog Commander™ drillingmotors ranging from 121 mm (4 3/4”) to 245 mm (9 5/8”)in size. This kick pad is adjustable to match the low sideof the motor to increase build rate capabilities. It will alsoallow lower adjustable settings for similar build rates,thereby reducing radial stresses applied to the bearingassembly, and permit safer rotation of the motor. Theycan be installed in the field by screwing them onto spe-cially adapted bearing housings.
3.7 STABILIZATIONBearing housings are also available with two stabilizationstyles, integral blade and screw-on. The integral bladestyle is built directly onto the bearing housing and thuscannot be removed in the field. The screw-on style pro-vides the option of installing a threaded stabilizer sleeveonto the drilling motor on the rig floor in a matter ofminutes. The drilling motor has a thread on the bottomend that is covered with a thread protector sleeve whennot required. Both of these styles are optional to a stan-dard slick bearing housing.

4.0 APPLICATIONS
The versatility and variety of Computalog Commander™drilling motors allows it to be used in several differentdownhole applications. As the variety of designs expand,the applications that Computalog Commander™ drillingmotors can operate in will also grow.
4.1 PERFORMANCE DRILLINGComputalog Commander™ drilling motors can be usedfor performance drilling. The wide variety of torque,speed, and flow rate capabilities of the drilling motorslend themselves easily to a wide range of bit types andformation conditions. Rotary drilling can also be appliedin addition to rotation from the drilling motor forincreased bit speed as required. Power is provided direct-ly at the bit, reducing wear and stress to drill string com-ponents, and increasing component life substantially.
4.2 DIRECTIONAL DRILLINGDirectional drilling began as a remedial operation tosolve a drilling problem; usually a fish or junk left in thehole. Today, with the creation of tighter legal spacingrequirements, better reservoir engineering modeling,and drilling of multiple wells from a single surface loca-tion, it has become very important to both control thewellbore position during drilling and to relate to theposition of existing wellbores to lease boundaries, otherwells, etc.
The most obvious application for directional drilling is fordrilling to areas that are inaccessible to conventional ver-tical drilling techniques. When drilling into reservoirs thatare under mountains, water, cities, or environmentallysensitive areas, wells can be directionally controlled to hitthe required target. When the reservoir is near problem-atic formations (ie. salt formations, steep fault planes,etc.) directional drilling techniques can be used to avoidthem and minimize their effect on drilling and recoveryprocesses.
Another capability with directional drilling is the drillingof multiple wells from a single point. This is valuable inthe case of off-shore drilling rigs which require a signifi-cant investment in time and money. Multiple wells can bedrilled from a single point to various targets for opti-mized recovery, reducing drilling rig time and costs.
Directional drilling can also be used to drill relief wells. Insituations where a well becomes uncontrolled, a reliefwell can be drilled to intersect the original wellbore.Heavy mud can then be pumped down the relief well to“kill” the blowout well.

4.3 HORIZONTAL DRILLING / WELL RE-ENTRY
Horizontal drilling is the fastest growing branch of direc-tional drilling. In certain reservoirs, recovery can be dra-matically improved by directionally drilling a well hori-zontally (over eighty degrees inclination) for an extendedlength. Greater reservoir exposure allows for higher pro-duction rates at equivalent drawdowns.
In standard horizontal drilling practices, the build sectionof the well is drilled with a larger drilling motor and cas-ing is run to the start of the horizontal section. This cas-ing string insures wellbore integrity as the horizontal sec-tion is drilled. The build section can be drilled in varyingrates from long radius to short radius. The build rate isdependent on the hole conditions, required horizontaldimensions, and well economics.
A smaller drilling motor is then used to drill the horizon-tal component of the well. If the horizontal componentof the well is to be straight, it is recommended that thesmaller drilling motor be set between 1.5 and 1.8 degreesfor the horizontal and then rotated to maintain wellboreinclination. If any adjustments need to be made, thebend in the drilling motor can be used to correct the well-bore trajectory. Higher motor settings have been used todrill with, allowing aggressive turns in the lateral.
An extension of horizontal drilling is the drilling of multi-lateral wells. Multi-lateral wells have more than one hor-izontal wellbore emanating from a single wellbore. Thiscan be in the form of several horizontal wells fanning outradially from a single vertical well. The horizontal wellscan be on the same vertical plane, or be strategicallyplaced at different planes for multiple reservoirs. A sec-ond method is to sidetrack from an existing horizontalwell for penetration into other areas in the reservoir forfurther recovery.
In addition, the above techniques can be used to performwell re-entry. Existing wells are regularly re-entered forfurther recovery from the reservoir. Sidetracking can beperformed from both the build section as well as the hor-izontal section of the existing well to penetrate into areasnot drained with the original well.
4.4 AIR / MISTED DRILLINGCompressible fluids such as air, nitrogen, natural gas, etc.,can be used in combination with a lubricating fluid.Computalog Commander™ drilling motors have beenused extensively in this application.
Advantages of drilling with compressible fluids are thatbetter hole cleaning occurs, increasing penetration ratesand reducing rig time and costs. Lost circulation problemsare eliminated, formation damage is limited, and contin-ual drill stem testing of potential producing formationscan be performed.
When operating Computalog Commander™ drillingmotors with air, extra precautions must be taken to min-imize wear and extend drilling motor life.
13985 MOTOR Handbook.QXD 3/12/01 2:59 PM Page 12
13
It is recommended that when operating ComputalogCommander™ drilling motors with air, or any other com-pressible fluid, that a lubricating fluid be added to thesystem. As stated earlier, the interference between therotor and the stator creates small cavities along theirlength. As each cavity moves down the length of thepower section from the rotation of the rotor, the cavityvolume remains the same. However, for there to be apressure change in the air as the cavity progresses (whichis required for torque generation), the volume must alsochange. Therefore, as the cavity progresses, the pressurewill drop for torque development, and the volume of theair will increase. This increase in air volume results inblow-by of the power section at the bottom end, whichwill potentially damage the stator.
The purpose of a lubricating fluid is to help lubricate thesurfaces between the rotor and stator of the power sec-tion, as well as provide some cooling assistance to reducethis blow-by damage. As the amount of lubricating fluidis decreased, wear to the rubber will increase, significant-ly reducing the life of the drilling motor.
When operating a Computalog Commander™ drillingmotor with air, care should be taken not let it run freelyat any time. This will cause the rotor to spin at ratesbeyond what it was designed for, wearing it out prema-turely. When starting the drilling motor, some weight onbit should be applied before flow is stabilized at therequired drilling rate. This will provide some resistance tothe rotor in the stator and prevent it from over-running.Similarly, when stopping drilling, some weight on bitshould be maintained until there is no pressure dropacross the drilling motor. Failing to do so will cause pre-mature stator wear, as well as possibly cause an internaljoint to fracture or back-off.
Stalling out the drilling motor can also cause extensivewear quickly to the stator. When stall occurs, the rotorwill seal off with the stator, causing the air pressure insidethe drill string to gradually increase. When the drillingmotor is raised, the seal between the rotor and stator willgive, and the air will pass through. However, since thepressure is higher, and the flow rate has increased beyondthe capacity of the power section, the rotor will spin overallowable limits and the stator will wear out in a shortperiod of time.
When stalling occurs, it is not easily identifiable with apressure increase at surface. As the drilling medium iscompressible, the stall will not be immediately noticed.Therefore, the ROP should be used as a gauge for stalling.If the ROP drops off excessively, it should be considered anindication that the drilling motor has stalled.
Another concern when using a compressible fluid topower a drilling motor is explosive decompression. This isespecially the case for nitrogen gas. When the drillingmotor is being operated downhole, gases permeate intothe rubber components. The amount of gases that per-meate into the rubber are increased by higher pressuresbeing applied, and longer periods of use. However, thisinitial absorption of gases does not affect drilling motorperformance. Once the drilling motor is being pulled outof hole, the pressure on the rubber component is greatly
13985 MOTOR Handbook.QXD 3/12/01 2:59 PM Page 13
14
Computalog Commander™ Motor Handbook
decreased, allowing the gases to expand and coalescewithin the rubber. This creates blistering of the rubber,and possibly leads to chunking, affecting the integrity ofthe drilling motor.
In wells where the drilling motor is expected to see pres-sures above 10,000 kPa (1450 psi), explosive decompres-sion is possible when pulling out of hole. To minimize thiseffect, the rate at which the drilling motor is pulled out ofhole should be reduced to allow time for the permeatednitrogen gas to escape from the rubber in the drillingmotor without causing blistering. In wells that may be ofa concern, it is recommended that the drilling motor belaid down after the first run. Once again, it is not thepressure on the drilling motor that causes the explosivedecompression, but rather the rate of pressure drop therubber is exposed to. Downhole, the gas is still com-pressed in the rubber, and does not deform the rubber.Damage does not occur until the pressure on the rubber isdropped dramatically by over 10,000 kPa (1450 psi).
When drilling with air, the dump sub assembly dischargeports must be plugged off. The pressure drop across thedump sub will not be sufficient enough to close it undernormal air flow rates.
It is recommended that prior to air drilling that ourTechnical Services department review the well informa-tion with modeling to provide a suggested combinationof air flow rate and lubricating fluid flow rate. With allcompressible fluids, the performance of ComputalogCommander™ drilling motors vary greatly with small dif-ferences in these two flow rates. To provide optimum lifeand performance characteristics, it is suggested our pro-fessional team assist you with flow rates selection.
4.5 MOTOR PERFORMANCE UNDERTWO PHASE FLOW
Stator performance of positive displacement motors(PDM) used on underbalanced drilling operations is sig-nificantly affected by the flow rate, fluid type and lubri-cation provided by the drilling fluid. Several perform-ance tests have been conducted on drilling motors undertwo phase flow conditions revealing some interestingbehavior. Papers have been published presenting ideason how to choose motors through performance indica-tors or bench testing. These tests and discussions are use-ful in understanding limitations with PDM’s in two phaseflow conditions.
It is important to understand how the performance of aPDM is affected by two phase flow and make smallchanges in operating parameters when trying to improveperformance. The following is a list of points to considerwhen suspected drilling motor problems occur whiledrilling with two phase fluids:
* The higher the gas / liquid ratio (lower liquid rates)the easier it is to stall the motor even though thecombined equivalent flow rate is at maximum motorrating. Slippage or blow-by (onset of stalling) occurssooner and at lower differential pressures in twophase flow than single phase flow.
13985 MOTOR Handbook.QXD 3/12/01 2:59 PM Page 14
15
* Lower liquid rates may cause poor lubricationresulting in faster wear rates.
* The motor is likely being over run while circulatingthe drill string off bottom.
* When on bottom drilling, an increase in thecombined equivalent flow rate of 10% overmaximum recommended may help reduce stallingproblems.
* Allow the weight on bit to “drill off” before pullingup off bottom.
* Work closely with the operator and underbalanceddrilling engineer, to make small parameter changes
The torque performance curve of PDM’s used in twophase flow does not change significantly except the max-imum predicted differential pressure can not be achievedbefore the motor stalls thereby a lower maximum torqueoutput. The following graph (Figure 2) illustrates the typ-ical performance of a 121mm motor under several flowconditions but with similar equivalent combined flowrates. Note the significant drop in RPM at the samedifferential pressure. This drop in RPM combined withthe reservoir’s production and the degree of underbal-anced achieved (how much below reservoir pressure), canhave a significant affect on the rate of penetration.

4.6 SPECIALTY APPLICATIONSComputalog Commander™ drilling motors have alsobeen used to drill conduit holes to accommodatepipelines cable, and other transmission mediums. Theseholes are generally drilled to traverse obstacles in a pro-posed right of way which present problems to conven-tional trenching methods; river crossings, steep or unsta-ble terrain, shore approaches, or environmentally sensi-tive areas.
Extraction of water soluble minerals (ie. salt, potash) canbe attained through solution mining technologies. In thispractice, “paired” wells are drilled to predetermined tar-gets and water is circulated through the holes untilcommunication is established. Water is then forced downone hole and allowed to exit through the other with it’smineral in solution.
Grout holes can be drilled to stabilize unconsolidated for-mations or isolate water bearing formations. Properplacement and control will result in reduced overall costsand greater technical efficiencies for the procedure.
Methane and water drainage holes have been commonin the mining industry for years. Similar techniques arebeing employed in the environmental industry for in situevacuation of toxic contaminants left in industrial andwaste disposal sites.

5.0 COMPUTALOG COMMANDER™DRILLING MOTOR OPERATION
In order to get the best performance and optimum life ofComputalog Commander™ drilling motors, the followingstandard procedures should be followed during opera-tion. Slight variations may be required with changes indrilling conditions and drilling equipment, but attemptsshould be made to follow these procedures as closely aspossible.
5.1 ASSEMBLY PROCEDURE AND SURFACE CHECK PRIOR TO RUNNING IN HOLE
Although all Computalog Commander™ motors areshipped from the shop thoroughly inspected and tested,some initial checks may be completed prior to running inhole. These surface check procedures should only be usedwith mud drilling systems.
CAUTION: To avoid potential bit, motor, and BOP dam-age, these preliminary checks should be com-pleted without a bit attached. A thread pro-tector should be installed in the bit box when-ever moving the motor, but must be removedbefore flow testing.
1. The correct lift sub must always be installed and usedfor moving the tool on or off the rig floor, and forlifting the tool into position for make-up. Also besure the connection between the lift sub and thedrilling motor is tight. To lift the drilling motor to therig floor, use a tugger line secured around the liftsub. Pick up the Computalog Commander™ drillingmotor with the elevators and set it into the slips ofthe rotary table. Install the dog collar / safety clamps.
NOTE: The lift sub supplied with the drilling motorshould only be used for lifting the drillingmotor. The capacity of the lift sub is restrictedto the weight of the drilling motor and shouldnot be used for any other purpose.
NOTE: Only apply rig tongs on the identified areas ofthe drilling motor. All connections of thedrilling motor are torqued in ComputalogLtd.’s service shop. Further make-up on the rigfloor is not necessary, and if attempted maycause damage.
2. Remove the lift sub and connect the kelly to thedrilling motor, remove the dog collar / safety clamp,and lift the drilling motor out of the slips. Removethe thread protector from the bit box and inspect thethreads for damage.

Computalog Commander™ Motor Handbook
3. Lower the drilling motor until the dump sub ports arebelow the rotary table, yet still visible.
CAUTION: The dump sub valve will remain open untilthere is enough fluid pressure to close it.Therefore, the drilling motor should be low-ered until the ports are below the rotarytable. This will prevent the initial flow ofdrilling fluid from spraying on the rig floor.
4. Slowly start the pumps and ensure drilling fluid isflowing out of the dump sub ports. Increase the flowrate until the dump sub ports close, and drilling fluidstops flowing out. Make note of the circulation rateand standpipe pressure.
CAUTION: Do not exceed the maximum recommendedflow rate for this test.
5. Lift the drilling motor until the bit box becomesvisible. It should be rotating at a slow, constantspeed. Listen to the bearing section of the drillingmotor for excessive bearing noise, especially if thetool has been used previously without being serviced.
6. Before stopping the pumps, the drilling motor shouldbe lowered below the rotary table. Ensure thatdrilling fluid flows out of the dump sub ports aftershutting down the pumps. It is possible that thedump sub valve remains closed after this test due toa pressure lock. If this occurs, no drilling fluid willflow out of the ports. To remove the pressure lock,bleed off some stand pipe pressure and the valve willopen.
CAUTION: The surface check should be as short as possi-ble; it is merely to ensure that the drillingmotor is rotating.
7. After this surface check, the bit should be attached tothe motor using a bit-breaker, while holding the bitbox stationary with a rotary tong. Be sure to avoidcontacting the end cap directly above the bit boxwith the tong dies.
CAUTION: It is recommended that you never hold the bitbox stationary and rotate the drilling motorcounter-clockwise, or hold the drilling motorstationary and rotate the bit box clockwise.This could possibly cause the internal drillingmotor connections to back off and damage it.Although rotating in the opposite directionwill result in drilling fluid to be pushed outthe top end, the internal connections will notbe at risk of disconnecting.
8. If the drilling motor has been used previously, anoverall inspection should be completed. Inspect forseal integrity by cleaning the area above the bit boxand visually checking for lubricating oil leakage orseal extrusion. General visual inspection of the entiredrilling motor should be carried out to check formissing oil plugs, housing damage, or looseconnections.
9. Set the adjustable assembly to the desired bend. Theinstructions for this procedure can be found in theappendix of this handbook. A copy is also attached toeach motor before it is sent out from the serviceshop. The torque required on the adjustableassembly is also indicated in the motor specifications.
13985 MOTOR Handbook.QXD 3/12/01 2:59 PM Page 18

10. If a float sub is used, it should be placed immediatelyabove the drilling motor.
5.2 TRIPPING IN HOLEGenerally, a drill string with a Computalog Commander™drilling motor can be run into the hole like a standardbottom hole assembly. The drilling motor is rugged, butcare should be taken to control travel speed while trip-ping into the hole. The drill string should be tripped withthe blocks unlocked and special care must be taken whenpassing the B.O.P., casing shoe, liner hanger, bridges andnearing bottom. Tight spots should be traversed by start-ing the pumps and slowly reaming the drilling motorthrough. When reaming, the drill string should be peri-odically rotated to prevent sidetracking.
When tripping to extreme depths, or when hole temper-atures are high, periodic stops are recommended tobreak circulation. This prevents bit plugging and aids incooling the drilling motor, preventing high temperaturedamage.
Fluid should not be circulated through a drilling motorinside casing if a PDC or diamond bit is being used, as thismay damage the bit cutters.
If a dump sub assembly is not used and the pipe is notbeing filled while tripping in, the back pressure on thepower section will cause the rotor to turn in reverse. Thiscould cause internal connections of the drilling motor tounscrew.
CAUTION: Stop and break circulation before puttingdrilling motor on-bottom. Failure to do socould plug jets and / or damage the drillingmotor.
5.3 DRILLINGWhen the assembly has been tripped to the bottom ofthe hole, Computalog Commander™ drilling motorsshould be operated in the following manner:
1. With the bit 1-2 meters (3-6 feet) off bottom, startthe pumps and slowly increase the flow rate to thatdesired for drilling. Do not exceed the maximumrated flow rate for the Computalog Commander™
drilling motor.
2. Make a note of the flow rate and the total pumppressure. Note that the pressure may exceed thecalculated off bottom pressure due to some side loadeffects between the bit and the hole diameter.
3. After a short cleaning interval, lower the bit carefullyto bottom and slowly increase the weight. Note thattorque can be affected by a dirty, uncirculated holeand the hole should be adequately cleaned prior toorienting the tool. Fill may be cleaned out of the wellbore by slowly rotating the drilling motor or bystaging the drilling motor full circle 30° to 45° at atime. This prevents ledge buildup and side tracking.
13985 MOTOR Handbook.QXD 3/12/01 2:59 PM Page 19
20
Computalog Commander™ Motor Handbook
4. Orient the drill string as desired and slowly applyfurther weight onto the bit. Pump pressure will riseas the weight on bit is increased. Note the change insystem pressure between the off bottom and onbottom values. This will be the differential pressure.Try to drill with steady pump pressure by keeping asteady flow rate and constant weight on bit.
NOTE: Adding weight on bit will cause both the dif-ferential pressure and torque to increase.Similarly, reducing weight on bit will reduceboth the differential pressure and the torque.Therefore, the rig pressure gauge enables theoperator to monitor how the drilling motor isperforming, as well as a weight on bit indica-tor.
CAUTION: Applying excessive weight on bit may causedamage to the on-bottom thrust bearings.Similarly, applying excessive tension whilestuck may cause damage to the off-bottomthrust bearings. Please refer to the specifica-tions for the recommended maximum loadsfor these conditions.
CAUTION: Do not exceed the maximum recommendeddifferential pressure as listed in the specifica-tions. Failure to do so could result in prema-ture wear or damage to the drilling motor sta-tor.
NOTE: Optimum differential pressure can be deter-mined by monitoring motor performance,penetration rate, and drilling requirements.Also, maintaining a constant weight on bitand differential pressure assists in controllingorientation of the drill string.
5.4 REACTIVE TORQUEA Computalog Commander™ drilling motor drives the bitwith a right-hand (clockwise) rotation. As weight isadded to the bit, reactive torque acting on the drillingmotor housing is developed. This left-hand (counter-clockwise) torque is transferred to the drill string and maycause the joints above the motor to tighten. Reactions ofthis type increase with larger weight on bit values andreach a maximum when the motor stalls. This reactivetorque also affects the orientation of the motor when itis used in directional drilling applications. Therefore, thisreactive torque must be taken into account when orient-ing the drilling motor from the surface in the desireddirection.
5.5 DRILLING MOTOR STALLStalling usually occurs when the application of excessiveweight on bit or hole sloughing stops the bit from rotat-ing and the power section of the drilling motor is notcapable of providing enough torque to power through.This is indicated by a sudden sharp increase in pump pres-sure. This pressure increase is developed because therotor is no longer able to rotate inside the stator, forminga long seal between the two. If circulation is continued,
13985 MOTOR Handbook.QXD 3/12/01 2:59 PM Page 20
21
the drilling fluid forces it’s way through the power sec-tion by deflecting the stator rubber. Drilling fluid will stillcirculate through the motor, but the bit will not turn.Operating in this state will erode and possibly chunk thestator in a very short period of time, resulting in extensivedamage. It is very important to avoid this operating con-dition.
When stalling occurs, corrective action must be takenimmediately. Any rotary application should be stoppedand built up drill string torque released. Then the weighton bit can be reduced allowing the drill bit to come looseand the drilling motor to turn freely. If the pump pressureis still high, the pumps should then be turned off. Onceagain, failure to do this will result in the stator erodinguntil the drilling motor is inoperable.
5.6 BIT CONDITIONSThe bit speeds developed when drilling with a drillingmotor are normally higher than in conventional rotarydrilling. This application tends to accelerate bit wear.When drilling with a drilling motor and simultaneouslyrotating the drill string, it is important to avoid lockingup the bit and over running the drilling motor with therotary table. A locked bit will impart a sudden torqueincrease in the drilling motor which can be detected by asudden, sharp increase in standpipe pressure. If thisoccurs, disengage the rotary table and reduce the flowrate. Backlash may occur from reactive torque distributedin the drill string as described in the section above. Failureto react in this situation may cause drilling motor dam-age.
5.7 ROTATING THE DRILLING MOTORFor directional control, it is sometimes necessary to rotatea drilling motor which has the adjustable assembly set fora deviation angle. It has been found that rotating thedrilling motor set at bends greater than 1.83 degrees mayfatigue the housings of the drilling motor to a pointwhere a fatigue crack is initiated, and fracture occurs.Therefore Computalog Ltd. has a policy that drillingmotors set at 1.83 degrees or less may be rotated down-hole with little risk of fatigue. Rotating at an anglegreater than 1.83 degrees is not recommended.
Although fractures from fatigue due to rotating over1.83 degrees are a relatively rare occurrence, a risk is stillbeing taken when it is done. The operator of the drillingmotor must be aware of this risk.
It is also recommended that the speed of rotation notexceed 60 RPM. If this value is exceeded, excessive cyclicloads would occur to the drilling motor housings and pos-sibly cause premature fatigue problems.
5.8 TRIPPING OUTPrior to tripping out when drilling with conventionalmud, it is recommended that the fluid be circulated for at
13985 MOTOR Handbook.QXD 3/12/01 2:59 PM Page 21
22
Computalog Commander™ Motor Handbook
least one “bottoms-up” time to ensure that the well-borehas been cleaned thoroughly.
The tripping out procedures for a ComputalogCommander™ drilling motor are basically the same asthose for tripping in. Taking care when pulling thedrilling motor through tight spots, liner hangers, casing,casing shoes, and the B.O.P. is necessary to minimize pos-sible damage to both the drilling motor and the wellhead components. Rotating may also be done to assistwith the removal of the drill string. The dump sub valvewill allow the drill string to be emptied automaticallywhen tripping.
Although the drill string will drain when tripping out, thedrilling motor itself may not. Once the drilling motor is atsurface, rotating the bit box in a counter-clockwise direc-tion will naturally drain the drilling motor through thetop. This is recommended before laying down aComputalog Commander™ drilling motor since aggres-sive drilling fluids can deteriorate the elastomer statorand seals. Fresh water should also be flushed through toensure thorough cleaning of the drilling motor. Also,clean the bit box area with clean water and install athread protector into the box connection.
NOTE: Rotating the bit box in a clockwise directionwill naturally drain the drilling motor throughthe bottom, but one of the internal connec-tions may break and unscrew. For this reason,it is not recommended to rotate it in this man-ner.
5.9 SURFACE CHECKS AFTER RUNNINGIN HOLE
Before laying down a Computalog Commander™ drillingmotor, it should be inspected in the event that it isrequired again before servicing. Listen for indications ofinternal damage when draining the drilling motor.Inspect the seal area between the bit box and the bear-ing section for lubricating oil leakage, and check theentire drilling motor for loose or missing pressure plugs.If there are any concerns with the drilling motor, it shouldbe laid down for servicing.

6.0 DRILLING FLUIDS
The Computalog Commander™ drilling motor isdesigned to operate effectively with practically all typesof drilling fluids. Successful runs have been achieved withfresh or salt water, with oil based fluids, with additives forviscosity control or lost circulation, and with nitrogen gas.However, some consideration should be taken whenselecting a drilling fluid, as elastomer components of thedrilling motor are susceptable to premature wear whenexposed to certain fluids.
Hydrocarbon based drilling fluids can be very harmful toelastomers. A measure of this aggressiveness is called theAniline Point. The Aniline Point is the temperature atwhich equal amounts of the hydrocarbon and anilinebecome miscible. This temperature is an indication of thepercent of light ends (aromatics) present in the hydrocar-bon. It is recommended that the aniline point of anydrilling fluid not be lower than 94.5°C (200°F). Also, it isstrongly recommended that the operating temperatureof the fluid be lower than the aniline point. Operatingoutside these parameters tends to excessively swell elas-tomers and cause premature wear, thus reducing the per-formance of the motor. In cases where hydrocarbonbased fluids are used it is recommended that stators thataccount for the elastomer swelling be used. These specialorder drilling motors may be requested with sufficientnotice. For any information regarding availability ordelivery, please contact your nearest Computalog Ltd.representative.
Drilling fluids with high chloride content can cause sig-nificant damage to internal components. When thesecomponents become damaged, the drilling motor’s per-formance is dramatically reduced.
Lost circulation materials can be used safely withComputalog Commander™ drilling motors but care mustbe taken to add the material slowly to avoid plugging thesystem. The percentage of solids should be kept to a min-imum. Large amounts of abrasive solids in the drillingfluid will dramatically increase the wear on a stator. It isrecommended that the solids content be kept below 5%for an acceptable operational life. Similarly, it is recom-mended that fine abrasives such as sand be kept lowerthan 0.5% as they are extremely damaging to the statorelastomer.
For the above reasons, it is extremely important to flushthe drilling motor with fresh water before laying it down,especially when working with the types of drilling fluidsdescribed above. Failure to do so will allow the drillingfluid to further seriously deteriorate components to thedrilling motor long after it has been operated.
13985 MOTOR Handbook.QXD 3/12/01 2:59 PM Page 23
24
7.0 TEMPERATURE LIMITS
The temperature limits of Computalog Commander™drilling motors again depend on the effect of differentfluids and temperatures on the components made ofelastomers. Generally, standard drilling motors are ratedfor temperatures up to 105°C (219°F). At temperaturesabove this, the performance characteristics of elastomersare changed, resulting in reduced life expectancy. Whenexposed to higher temperatures, the elastomers swell,creating more interference than desired, wearing theparts out prematurely. The strength of the elastomers isalso affected.
To compensate for these elastomer changes, specialmaterials and special sizes of components are used. Thisresults in drilling motors that are specifically assembledfor high temperatures. These special order drilling motorsmay be operated in temperatures up to 150°C (300°F) andhigher. They may be requested with sufficient notice. Forany information regarding availability or delivery, pleasecontact your nearest Computalog Ltd. representative.
It should be noted that a Computalog Commander™drilling motor manufactured for hot hole conditions willnot perform as indicated in these specifications in lowertemperatures. The rubber in the stator is specially select-ed for more clearance at higher temperatures to mini-mize interference. Therefore, at lower temperatures, thestator elastomer will not seal adequately on the rotor,and fluid bypass will occur. Therefore, it is important thatthe drilling motor be used in the conditions it is designedfor in order to operate as required.

8.0 TROUBLESHOOTING DOWNHOLE
Careful attention to variations in the fluid pressure canidentify many common downhole problems. In manycases, corrective measures may save a costly trip. Beloware listed some symptoms that are sometimes experi-enced when drilling, in conjunction with some of theirpossible causes when dealing with ComputalogCommander™ drilling motors. Also listed are what meas-ures would be taken to correct the problem and continuedrilling.
NOTE: At any time that there are problems incurredwhile drilling, it is strongly suggested that allpossible surface problems are identified andcorrected before assuming the problem isrelated to the downhole equipment. This willminimize any trip time for pulling out thedown-hole equipment unnecessarily.
8.1 WITH BIT OFF BOTTOM1. Circulation pressure is lower than calculated.
A. Dump Sub Valve Stuck Open - Turn flow rate onand off in an attempt to shut the valve. Use vary-ing flow rates. Also, the drill string can bestroked one stand long to help loosen the valve.If unable to close the dump sub valve, it may benecessary to pull out of hole.
B. String Washout - normal drill string washout pro-cedures apply
C. Lost Circulation - normal lost circulation proce-dures apply
2. Circulation pressure is higher than calculated.
A. Drilling Motor or Bit Plugged - This usually coin-cides with little or no circulation. Once allhydraulic systems have been checked and veri-fied, it may be necessary to pull out of hole.
B. Excessive bit side loading due to under gaugehole or high adjustable assembly bend angle -This usually coincides with full circulation. If thedrilling motor is too tight against the wall of thewellbore, the bit may start sidetracking.Corrective measures include drilling a kelly downto reduce side loading or reducing the bendangle on the drilling motor. If sidetracking is aconcern, the drilling motor should be run with alower flow rate to prevent it.
8.2 WITH BIT ON BOTTOM1. Circulation pressure is lower than calculated.
A. Dump Sub Valve Stuck Open - Turn flow rate onand off in an attempt to shut the valve. Use vary-ing flow rates. Also, the drill string can bestroked one stand long to help loosen the valve.If unable to close the dump sub valve, it may benecessary to pull out of hole.
B. String Washout - normal drill string washout pro-cedures apply
C. Lost Circulation - normal lost circulation proce-dures apply
13985 MOTOR Handbook.QXD 3/12/01 2:59 PM Page 25
26
D. Worn or Damaged Stator - with certain drillingfluids, stators may wear prematurely, resulting innoticeable weakening over it’s usage. As the sta-tor wears, the speed of the drilling motor will bereduced. Therefore, indications of a worn statorwill be a drop in the ROP, or an increase in thedifferential pressure required to produce thesame ROP.
E. Gas Kick - normal gas kick procedures apply
2. Circulation pressure is higher than calculated.
A. Drilling Motor or Bit Plugged - This usually coin-cides with little or no circulation. Remove theweight on bit, allow the bit to drill off, and thenstop the pumps. If the pressure remains high, it ispossible that the drilling motor or all the bit jetsare plugged. Once all hydraulic systems havebeen checked and verified, it may be necessary topull out of hole.
B. Excessive bit side loading due to under gaugehole or high adjustable assembly bend angle -This usually coincides with full circulation. If thedrilling motor is too tight against the wall of thewellbore, the drilling motor may be working toohard and the torque requirement will be greaterthan the recommended value for the drillingmotor size. Corrective measures include reducingweight on bit or reducing the bend angle in thedrilling motor.
C. Drilling Motor Stalled or Stalling - Usually coin-cides with pressure increase. Rotary applicationshould be stopped and any built up string torqueslowly released. The weight on bit can then bereduced allowing the drill bit to come loose andthe drilling motor to turn freely. If the pumppressure is still high, the pumps should be turnedoff. These steps must be followed in close succes-sion to reduce potential stator damage.
D. Mud Rings - occur when cuttings accumulatearound tool joints. They cause the string to stickand prevent sliding. Use standard mud treatmentprocedures.
3. Change or Loss of rate of penetration.
A. Drilling Motor Stalled - Usually coincides withpressure increase. Rotary application should bestopped and any built up string torque slowlyreleased. The weight on bit can then be reducedallowing the drill bit to come loose and thedrilling motor to turn freely. If the pump pressureis still high, the pumps should be turned off.These steps must be followed in close successionto reduce potential stator damage.
B. Worn Stator - Refer to worn stator info under‘Circulation pressure is lower than calculated’above.
C. Change of Formation - Adjust the flow rate andweight on bit to optimize drilling performancefor the new formation conditions.
D. Drill String / Stabilizers Hung Up - Normal correc-tive procedures apply
E. Bit Worn or Balling - Normal bit wear or ballingprocedures apply.

9.0 DRILLING MOTOR SPECIFICATIONS
MOTOR SPECIFICATIONSListed here are the performance specifications of thedrilling motor, including minimum and maximum flowrate capacities, and minimum and maximum bit speed atfull load differential pressure. (Full load differential pres-sure is defined as the maximum differential pressure thedrilling motor is capable of operating under with accept-able wear rates and life expectancy. Tyically, the full loaddifferential pressure is also affected by the flow rate; thegreater the flow rate, the lower the full load differentialpressure). Also in the specification is the maximumtorque capacity that correlates with the full load differ-ential pressure of the minimum specified flow rate. Themaximum power is calculated from the maximum bitspeed and the maximum torque for the full load differ-ential pressure for the maximum flow rate specified. Themaximum allowable bit pressure drop is given. If thisvalue is exceeded, premature wear may occur to the seal-ing assembly.
DIMENSIONAL DATA Typical dimensions including length to bend, over-alllength, length to upsets, as well as maximum outer diam-eters for various padding arrangements. Also includedare the wellbore diameters that the drilling motors arerecommended for, top and bottom connection specifica-tions and total weight.
ULTIMATE LOAD FACTORSMaximum loads that may be applied to the drilling motorunder operating conditions. Pull To Yield Motor is thetensile load required to yield one of the housing connec-tions of the drilling motor. Maximum static and dynamicbit loads are also given.
ESTIMATED BUILD RATESA table is given correlating the adjustable bend settingand common wellbore diameters with an estimated buildrate. However, as conditions vary downhole, these esti-mates may be inaccurate for some wells. Caution shouldbe used when referring to these values as experiencewith certain formations will allow for a more informedestimate of the expected build rate. Also given in this sec-tion is the torque required for the adjustable assembly.
PERFORMANCE CHARTSCharts for both metric and imperial units are shown toprovide operational characteristics over the full range offlow rates and differential pressures for the drillingmotor. Each chart Is actually two charts laid over eachother. The two components of each chart are describedbelow, as well as instructions in how to read them.
13985 MOTOR Handbook.QXD 3/12/01 2:59 PM Page 27
28
Computalog Commander™ Motor Handbook
RPMThe first component of the chart is the RPM line. Acrossthe bottom of the chart is differential pressure (kPa/psi).The differential pressure is the difference between thesystem pressure when the drilling motor is on-bottom(loaded) and off-bottom (not loaded). On the left side ofthe chart is the speed (RPM). These are the scales to beused when using the horizontal RPM lines on the chart.The horizontal lines start at the speed axis of the chartand begin to drop off slightly as differential pressureincreases. They eventually end somewhere past the fullload lines (vertical lines). These RPM lines are usually laidout as three lines, each for a different specified flow rate.The specified flow rates can be seen slightly above theline.
The RPM lines are used to determine what the drillingmotor RPM is, knowing what the flow rate and differen-tial pressure are. Using the chart in Figure 3 for a 121 mm(4 3/4”) Computalog Commander™ MN 4535 drillingmotor, if the flow rate is 660 lpm (175 GPM) and the dif-ferential pressure is 2700 kPa (390 psi), the speed of thedrilling motor would be approximately 155 RPM. For flowrates different than the ones given on the chart, lines canbe interpolated between the lines, then RPM read.
The chart shows what happens to the speed of thedrilling motor as differential pressure is increased. For themost part, the drop in RPM as differential pressureincreases is slight until the full load line is crossed. At thatpoint the RPM drops quickly to zero, which is stall mode.
Therefore, it is important to not go beyond the maximumrecommended operating differential pressure, or thedrilling motor will be operating inefficiently and wearwill occur.
TORQUEThe second component of the chart is the torque line. Onthe right side of the chart is the torque scale (N-m, ft-lbs).The torque line is used with this scale and the differentialpressure scale across the bottom. The torque line starts at0 differential pressure and 0 torque and increases linear-ly as diferential pressure increases. The same torque lineis used for the various flow rates because torque is inde-pendent of flow rate.
The torque output of the drilling motor can be deter-mined by knowing the differential pressure across thedrilling motor. Using the chart in Figure 3, if the differ-ential pressure is 2700 kPa (390 psi), the output torquefrom the drilling motor is approximately 1450 N-m(1050 ft - lbs).
13985 MOTOR Handbook.QXD 3/12/01 2:59 PM Page 28
29
FULL LOADAlso on the charts are full load lines. These lines indicatethe maximum recommended operating differential pres-sures of the drilling motor. If the differential pressuregoes beyond these maximum values, the operating life ofthe stator will be reduced. Excessive pressure drop acrossthe rotor and stator will cause pre-mature pressure washor chunking, and impair performance.
For some designs of drilling motors this maximum recom-mended operating differential pressure varies with theflow rate. The flow rate each full load line correlateswith is written within the line. Flow rates between thesevalues may have their full load lines interpolated. If onlya single full load line is on the performance chart, it isused for the full range of flow rates.

Appendix #5 Rotor By-Pass Nozzle Instructions
CALCULATIONS - METRIC
All Computalog Commander™ M and L selections ofdrilling motors 95 mm (3-3/4”) and larger have rotors thathave a bore cut through the center to facilitate fluid flowrates greater than the capacity of the power section. Byusing a nozzle on this bore, partial fluid flow can passbetween the rotor and stator, up to the maximum allow-able capacity, with the additional fluid flow goingthrough the rotor.
At start-up, as fluid flow rate is increased, all fluid willpass through the rotor. The friction between the rotorand stator will prevent it from rotating. EventuaIIy thepressure drop across the rotor nozzle will be greater than
FIGURE 5.1: Drilling Motor Assembly
13985 Computalog 110 -end. qxd 3/12/01 3:12 PM Page 146
147
the pressure drop required to overcome the frictionallosses between the rotor and the stator, and the drillingmotor will start to rotate. If the correct nozzle has beenselected, once the full flow rate is achieved and therequired pressure differential is achieved, the drillingmotor should have a portion of the flow approximatelyequal to its maximum specified capacity passing betweenthe rotor and the stator. The remaining portion of theflow will pass through the rotor. For equilibrium, duringall operations, the pressure drop across the rotor and sta-tor wiII be equal to the pressure drop across the rotornozzle.
Therefore, the drilling motor will operate in the follow-ing way. Once full flow rate is achieved, and no weighthas been applied to the bit, excessive fluid flow will passbetween the rotor and stator. Once weight is applied onthe bit, the differential on the rotor and stator will be atthe value that the nozzle was sized for, splitting the flowas desired.
Therefore, extra precautions should be observed whenworking with Computalog Commander™ drilling motorsusing rotor-by-pass. Extra care should be taken when nothaving weight on bit and the length of time this occursmust be minimized. Failing to do so will cause prematurewear and damage to the stator from excessive flow.
In order to size a nozzle for a specific situation, three fac-tors are required:
1. Total Required Flow Rate, Qr : This is the total flowrate of the drilling fluid as required for properdrilling operation
2. Required Motor Pressure Drop, Pm : The estimatedpressure drop (differential pressure) of the drillingmotor when down-hole
3. Mud Weight, MW:
Once these factors are known, the required nozzlesize can be selected in the following way. First, theflow rate that is to pass through the rotor nozzle Qnis calculated. To determine this value subtract themaximum flow rate capacity of the size and seriesComputalog Commander™ drilling motor to be usedfrom the total required flow rate Qr.
The nozzle area required for this operation can thenbe calculated using the following formula:

The size of nozzle required can then be determinedby looking at the enclosed table for nozzle sizes inAppendix 12.
The design of the nozzle assemblies vary for the dif-ferent sizes of drilling motors, so instructions forinstalling each one are described seperately below.
