2.0 MOTOR SELECTION

The handbook specifications are broken into foursections, each section grouping together mudlubricated drilling motors of common characteris-tics. The four sections are as follows:

4



March 2005 5

Standard Drilling Motors (N Designation) -These drilling motors use power sections of medi-um length which provide a wide selection of speeds, but provide mid-range maximum torqueand horsepower outputs. They work well in appli-cations where high torque is not required, such asdrilling soft formations, drilling with roller conebits, etc. These drilling motors can be identified

with the use of the letter "N" as the last letterused before the number in the Series Number (ie.HN1240).

Performance Drilling Motors (E or ADesignation) - These drilling motors use extend-ed or air power sections and provide a wide selec-tion of speeds, as well as high values of torque

and horsepower. They are ideal for applicationswhere high torques are required such as drilling inhard formations with PDC bits, etc.. These drilling motors are identified by the letters "E" or "A" asthe last letter before the numbers in the SeriesNumbers (ie. LE6754). The "A" designation isused for motors that have been designed for usein air drilling, but are also widely used whendrilling with the full ranges of drilling fluids. The

specifications in this handbook indicate the per-formance of this design of drilling motor withwater.

High Capacity Performance Drilling Motors (EDesignation) - These performance drilling motorshave been optimized for increased flow rates,rotary speeds, and torque outputs. They are used

in performance drilling applications where abovenormal flow rates are desired, such as whenneeding to clean a hole better due to increasedpenetration rates, as well as applications whereexcessive rotary speeds are desired. Similar tothe performance drilling motors, these drilling motors are identified by the letter "E" as the lastletter before the numbers in the Series Numbers(ie LE7875)

(1)ERT™ Performance Drilling Motors (XDesignation) - These are performance drilling motors that utilize even rubber thickness (ERT™)technology. Power sections of even rubber thick-ness typically have twice the efficiency of conven-tional power sections, and result in drilling motorsthat have twice as much torque capability as con-ventional performance drilling motors. They areideal for use with aggressive PDC bits and inapplications where absolute maximum torque isrequired, etc.. They are identified by the letter "X"in the front of the Series Numbers (ie. XME6748).

First Edition6

In addition to the above, PrecisionDrillTM drilling motors have designations indicating speedranges. These designations are the first letter of the Series Number (I.e. LN7830), except in thedesignations of the ERT™ Performance Drilling Motors, where they are the second letter (I.e.XMN4536). The designations used are as fol-lows:

H - High Speed

M - Medium Speed

L - Low Speed

3.0 COMPONENTS

PrecisionDrillTM drilling motors consist of severalmajor assemblies:

z Dump Sub Assembly

z Power Section

z Drive Assembly

z Adjustable Assembly

z Mud Lubricated Bearing Section

3.1 DUMP SUB ASSEMBLY

As a result of the power section (describedbelow), the drilling motor will seal off the drill

string ID from the annulus. In order to prevent wettrips and pressure problems, a dump sub assem-bly can be utilized. The dump sub assembly is ahydraulically actuated valve located at the top of the drilling motor, which allows the drill string tofill when running in hole and drain when tripping out of hole. When the pumps are engaged, thevalve automatically closes and directs all drilling fluid flow through the motor.

In the event that the dump sub assembly is notrequired or desired, such as in underbalanceddrilling using nitrogen gas or air, it’s effect can benegated by simply replacing the discharge plugswith blank plugs (4 3/4” and larger). This allowsthe motor to be adjusted as necessary, even inthe field. In all cases, the dump subs may bereplaced with top subs if desired.

3.2 CONVENTIONAL POWER SECTION

The PrecisionDrillTM drilling motor power section isan adaptation of the Moineau(2) type positive dis-placement hydraulic pump in a reversed applica-tion. It essentially converts hydraulic power fromthe drilling fluid into mechanical power to drivethe bit.

(2)Inventor of the Progressive Cavity Pump



March 2005 7

The power section is comprised of two compo-nents; the stator and the rotor. The stator consistsof a steel tube containing a bonded elastomerinsert with a lobed, helical pattern bore throughthe center. The rotor is a lobed, helical steel rod.When the rotor is installed into the stator, thecombination of the helical shapes and lobes formsealed flow cavities between the two compo-

nents. When drilling fluid is forced through thepower section, the pressure drop across the cavi-ties will cause the rotor to turn inside the stator.This is how the drilling motor is powered.

It is the pattern of the lobes and the length of thehelix that dictate what output characteristics willbe developed by the power section. By the natureof the design, the stator always has one morelobe than the rotor. The illustrations in Figure 1show a 1:2 lobe cross-section, a 4:5 lobe cross-section and a 7:8 lobe cross-section. Generally, asthe lobe ratio is increased, speed of rotation isdecreased.

The second control on power section output char-acteristics is length. A stage is defined as a fullhelical rotation of the lobed stator. Therefore,power sections may be classified in stages. A four

stage power section contains one more full rota-tion to the stator elastomer, when compared to athree stage. With more stages, the power sectionis capable of greater overall pressure differential,which in turn provides more torque to the rotor.

As mentioned, these two design characteristicscan be used to control the output characteristicsof any size of power section. This allows for the

modular design of PrecisionDrill

TM

drilling motors,making it possible to simply replace power sec-tions when different output characteristics arerequired.

In addition, the variation of dimensions and mate-rials will allow for specialized drilling conditions.With increased temperatures or certain drilling fluids, the stator elastomer will expand and forma tighter seal onto the rotor and create more of an

interference fit, which may result in stator elas-tomer damage. PrecisionDrillTM drilling motors areavailable when requested with stators that takethese conditions into account. This will result inminimal loss in performance for PrecisionDrillTM

drilling motors used in these specialized condi-tions.

3.3 PREMIUM NITRILE POWER SECTION

Further improvements to elastomer technologyhas provided the ability to improve the perform-ance characteristics of all power sections by over30%. This next generation nitrile is described aspremium nitrile, and is affected by oil based fluidsand temperature to lesser degrees than previousgenerations of elastomers. It is capable of han-

dling greater pressure drops and therefore is ableto create more output torque without increasedlength. This premium nitrile is available in nearlyall conventional designs.



First Edition8

3.4 ERTTM PERFORMANCE POWER SECTION

The next generation of performance drilling motors utilize ERT™ power section technology. Asshown in Figure 2, the cross-section profile of therotor and stator are the same as conventionalpower sections and operate in the same way asdescribed in 3.2 above. However, the ERT™ sta-

tor is designed differently. The steel tube of thestator is manufactured with a spiraled lobed pro-file machined through. A thin layer of elastomeris applied to the inside of this lobed profile, hencethe name even rubber thickness (ERT™). Whenthe rotor is inserted into the stator, the thin layerof rubber provides the flexible seal for the flowcavities of the power section, while the steelbehind the rubber provides a fixed support. This

design configuration results in several perform-ance benefits;

· Increased torque Capacity (double the efficiencyof conventional power sections)

· Reduced affects from rubber swell (constantchange in rubber thickness due to temperature,or fluid exposure, over a thinner cross-section)

· Stronger stator housing tube (stator is manufac-tured from one piece of material)

(ERT TM is a trademark of R&M Energy Systems.)

3.5 DRIVE ASSEMBLY

Due to the design nature of the power section,

there is an eccentric rotation of the rotor insidethe stator. To compensate for this eccentricmotion and convert it to a purely concentric rota-tion, PrecisionDrillTM drilling motors utilize a highstrength jointed drive assembly. The drive assem-bly consists of a drive shaft with a sealed andlubricated drive joint located at each end. Thedrive joints are designed to withstand the hightorque values delivered by the power section

while creating minimal stress through the driveassembly components for extended life andincreased reliability. The drive assembly also pro-vides a point in the drive line that will compensatefor the bend in the drilling motor required fordirectional control.

3.6 ADJUSTABLE ASSEMBLY

All PrecisionDrillTM drilling motors are suppliedwith a surface adjustable assembly. Theadjustable assembly can be set from zero to twoor three degrees in varying increments in thefield. This durable design results in wide range of potential build rates used in directional, horizon-tal and re-entry wells. Also, to minimize the wearto the adjustable components, the adjustable ring has an integrated wear pad that orients to the low

side of the bend.



March 2005

3.7 MUD LUBRICATED BEARING SECTION

The bearing section contains the radial and thrustbearings that transmit the axial and radial loadsfrom the bit to the drill string, while providing adrive line that allows the power section to rotatethe bit. Mud lubricated bearing sections allow alimited portion of the drilling fluid to be pumped

down through the drilling motor to be bypassedthrough the bearings, providing lubrication andcooling. The drilling fluid bypassing through thebearing section exits directly above the bit boxand rejoins the primary flow to help clean thehole.

3.8 STABILIZATION

Bearing housings are available with screw-onstyle stabilization. The screw-on style provides theoption of installing a threaded stabilizer sleeveonto the drilling motor on the rig floor in a matterof minutes. The drilling motor has a thread on thebottom end that is covered with a thread protec-tor sleeve when not required. Screw-on style bear-ing housings are the standard housings supplied.

3.9 KICK PADS

Eccentric kick pads can also be used onPrecisionDrillTM drilling motors ranging from4 3/4” (121 mm) to 9 5/8” (244 mm) in size. Thiskick pad is adjustable to match the low side of themotor to increase build rate capabilities. It willalso allow lower adjustable settings for similarbuild rates, thereby reducing radial stressesapplied to the bearing assembly, and permit saferrotation of the motor. They can be installed in thefield by screwing them onto specially adaptedbearing housings.

3.10 ROTOR CATCHES

PrecisionDrillTM drilling motors also come avail-

able with a rotor catch mechanism. In the eventthat a connection backs-off or twists-off, thissafety device will prevent any part of the drilling motor from being left in the hole. The catch man-drel is connected to the drilling motor rotor, andwill catch on the inside of the top-most sub of thedrilling motor, ensuring that when the bottom holeassembly is pulled out of hole it will bring the restof the drilling motor with it.

4.0 APPLICATIONS

The versatility and variety of PrecisionDrillTM

drilling motor allows it to be used in several dif-ferent downhole applications. As the variety of designs expand, the applications thatPrecisionDrillTM drilling motors can operate in willalso grow.

4.1 PERFORMANCE DRILLING

PrecisionDrillTM drilling motors can be used forperformance drilling. The wide variety of torque,speed, and flow rate capabilities of the drilling motors lend themselves easily to a wide range of bit types and formation conditions. Rotary drilling can also be applied in addition to rotation fromthe drilling motor for increased bit speed as

required. Power is provided directly at the bit,reducing wear and stress to drill string compo-nents, and increasing component life substantial-ly.

4.2 DIRECTIONAL DRILLING

Directional drilling began as a remedial operationto solve a drilling problem; usually a fish or junkleft in the hole. Today, with the creation of tighterlegal spacing requirements, better reservoir engi-neering modeling, and the drilling of multiplewells from a single surface location, it has

become very important to both control the well-bore position during drilling and to relate to theposition of existing wellbores to lease boundariesand other wells.

The most obvious application for directionaldrilling is for areas inaccessible to conventionalvertical drilling techniques. When drilling intoreservoirs under mountains, water, cities, or envi-ronmentally sensitive areas, wells can be direc-tionally controlled to hit the required target. Whenthe reservoir is near problematic formations (ie.salt formations, steep fault planes, etc.) direction-al drilling techniques can be used to avoid themand minimize their effect on drilling and recoveryprocesses.

Another capability with directional drilling is thedrilling of multiple wells from a single point. This

is valuable in the case of offshore drilling rigswhich require a significant investment in time andmoney. Multiple wells can be drilled from a singlepoint to various targets for optimized recovery,reducing drilling rig time and costs.

Directional drilling can also be used to drill relief wells. In situations where a well becomes uncon-trolled, a relief well can be drilled to intersect the

original wellbore. Heavy mud can then bepumped down the relief well to “kill” the blowoutwell.

4.3 HORIZONTAL DRILLING/WELL RE-ENTRY

In certain reservoirs, recovery can be dramatical-ly improved by directionally drilling a well horizon-tally (over eighty degrees inclination) for an

extended length. Greater reservoir exposureallows for higher production rates at equivalentdrawdowns.

Typically, the build section of the well is drilledwith a larger drilling motor and casing is run to thestart of the horizontal section. This casing string ensures wellbore integrity as the horizontal sec-tion is drilled. The build section can be drilled in

varying rates from long radius to short radius. Thebuild rate is dependent on the hole conditions,required horizontal dimensions, and well eco-nomics.



First Edition12

A smaller drilling motor is then used to drill thehorizontal component of the well. If the horizontalcomponent of the well is to be straight, it is rec-ommended that the smaller drilling motor be setat a slight angle for the horizontal and then rotat-ed to maintain wellbore inclination. If any adjust-ments need to be made, the bend in the drilling motor can be used to correct the wellbore trajec-

tory. Higher motor settings have been used todrill, allowing aggressive turns in the lateral.However,they result in higher loads on the drilling components and sharper changes in the horizon-tal trajectory, which is undesirable.

An extension of horizontal drilling is the drilling of multilateral wells. Multilateral wells have morethan one horizontal wellbore emanating from asingle wellbore. This can be in the form of severalhorizontal wells fanning out radially from a singlevertical well. The horizontal wells can be on thesame vertical plane, or be strategically placed atdifferent planes for multiple reservoirs. A secondmethod is to sidetrack from an existing horizontalwell for penetration into other areas in the reser-voir for further recovery.

In addition, the above techniques can be used to

perform well re-entry. Existing wells are regularlyre-entered for further reservoir recovery.Sidetracking can be performed from both buildsection and horizontal section of the existing wellto penetrate into areas not drained with the origi-nal well.

4.4 AIR/MISTED DRILLING

Compressible fluids such as air, nitrogen, naturalgas, etc., can be used in combination with a lubri-cating fluid.

There are many advantages to drilling with com-pressible fluids. Better hole cleaning occurs, aswell as increased penetration rates and reducedrig time and costs. Lost circulation problems areeliminated, formation damage is limited, and con-

tinual drill stem testing of potential producing for-mations can be performed.

When operating PrecisionDrillTM drilling motorswith air, extra precautions must be taken to mini-mize wear and extend drilling motor life. It is rec-ommended that a lubricating fluid be added tothe system. As stated earlier, the interferencebetween the rotor and the stator creates small

cavities along their length. As each cavity movesdown the length of the power section from therotation of the rotor, the cavity volume remainsthe same. However, for there to be a pressurechange in the air as the cavity progresses (whichis required for torque generation), the volumemust also change. Therefore, as the cavity pro-gresses, the pressure will drop for torque devel-opment, and the volume of the air will increase.

This increase in air volume results in blow-by of the power section at the bottom end, which canpotentially damage the stator.



March 2005

The purpose of a lubricating fluid is to help lubri-cate the surfaces between the rotor and stator of the power section, as well as provide some cooling assistance to reduce blow-by damage. As theamount of lubricating fluid is decreased, wear tothe rubber will increase, significantly reducing thelife of the drilling motor.

When operating a PrecisionDrillTM drilling motorwith air, care should be taken not let it run freelyat any time. This will cause the rotor to spin atrates beyond what it was designed for, wearing itout prematurely. When starting the drilling motor,some weight on bit should be applied before flowis stabilized at the required drilling rate. This willprovide some resistance to the rotor in the statorand prevent it from over-running. Similarly, whenstopping drilling, some weight on bit should bemaintained until there is no pressure drop acrossthe drilling motor. Alternatively, the total flow rateshould be reduced when off-bottom to reduce theRPM and vibration created. Once on-bottom, theflow can be increased to the required rates. Failing to follow these practices will cause premature sta-tor wear, as well as possibly cause an internal jointto fracture or back-off.

Stalling out the drilling motor can quickly causeextensive wear to the stator. When stall occurs, therotor will seal off with the stator, causing the airpressure inside the drill string to graduallyincrease. When the drilling motor is raised, theseal between the rotor and stator will give, and theair will pass through. However, since the pressureis higher, and the flow rate has increased beyondthe capacity of the power section, the rotor will

spin over allowable limits and the stator will wearout in a short period of time.

When stalling occurs, it is not easily identifiablewith a pressure increase at surface. As the drilling medium is compressible, the stall will not beimmediately noticed. Therefore, the ROP shouldbe used as a gauge for stalling. If the ROP dropsoff excessively, it should be considered an indica-

tion that the drilling motor has stalled.Another concern when using a compressible fluidto power a drilling motor is explosive decompres-sion. This is especially the case for nitrogen gas.When the drilling motor is being operated down-hole, gases permeate into the rubber compo-nents. The amount of gases that permeate intothe rubber are increased by higher pressuresbeing applied and longer periods of use. However,

this initial absorption of gases does not affectdrilling motor performance. Once the drilling motor is being pulled out of hole, the pressure onthe rubber component is greatly decreased, allow-ing the gases to expand and coalesce within therubber. This creates blistering of the rubber, andpossibly leads to chunking, affecting the integrityof the drilling motor.

13

In wells where the drilling motor is expected to seepressures above 10,000 kPa (1450 psi), explosivedecompression is possible when pulling out of hole. To minimize this effect, the rate at which thedrilling motor is pulled out of hole should bereduced to allow time for the permeated nitrogengas to escape from the rubber in the drilling motorwithout causing blistering. In wells that may be of

a concern, it is recommended that the drilling motor be laid down after the first run. Once again,it is not the pressure on the drilling motor thatcauses the explosive decompression, but ratherthe rate of pressure drop the rubber is exposed to.Downhole, the gas is still compressed in the rub-ber, and does not deform the rubber. Damagedoes 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 dis-charge ports must be plugged off (or the dumpsub replaced with a top sub). The pressure dropacross the dump sub will not be sufficient enoughto close it under normal air flow rates.

It is recommended that prior to air drilling thePrecision Energy Services Technical Services

department review the well information with mod-eling to provide a suggested combination of airflow rate and lubricating fluid flow rate. With allcompressible fluids, the performance of PrecisionDrillTM drilling motors vary greatly withsmall differences in these two flow rates. To pro-vide optimum life and performance characteris-tics, it is suggested Precision Energy Services pro-fessional team assist you with flow rates selec-

tion.

4.5 MOTOR PERFORMANCE UNDERTWO PHASE FLOW

Stator performance of positive displacementmotors (PDM) used on underbalanced drilling operations is significantly affected by flow rate,fluid type and lubrication provided by the drilling fluid. Several performance tests have been con-ducted on drilling motors under two phase flowconditions revealing some interesting behavior.Papers have been published presenting ideas onhow to choose motors through performance indi-cators or bench testing. These tests and discus-sions are useful in understanding limitations withPDMs in two phase flow conditions.

It is important to understand how the perform-ance of a PDM is affected by two phase flow andmake small changes in operating parameterswhen trying to improve performance.

The following is a list of points to consider whensuspected drilling motor problems occur whiledrilling with two phase fluids:

z The higher the gas / liquid ratio (lower liquidrates) the easier it is to stall the motor eventhough the combined equivalent flow rate is atmaximum motor rating. Slippage or blow-by

(onset of stalling) occurs sooner and at lowerdifferential pressures in two phase flow thansingle phase flow.

z Lower liquid rates may cause poor lubricationresulting in faster wear rates.

z The motor is likely being over run whilecirculating the drill string off bottom.

z When on bottom drilling, an increase in thecombined equivalent flow rate of 10% overmaximum recommended may help reducestalling problems.

z Allow the weight on bit to “drill off” beforepulling up off bottom.

z Work closely with the operator andunderbalanced drilling engineer to makesmall parameter changes.

The torque performance curve of PDMs used intwo phase flow does not change significantly,except that the maximum predicted differentialpressure cannot be achieved before the motorstalls thereby a lower maximum torque output.The following graph (Figure 3) illustrates the typi-cal performance of a 4-3/4” motor under severalflow conditions but with similar equivalent com-bined flow rates. Note the significant drop in RPMat the same differential pressure. This drop inRPM combined with the reservoir’s productionand the degree of underbalanced achieved (howmuch below reservoir pressure), can have a sig-nificant affect on the rate of penetration.

4.6 SPECIALTY APPLICATIONS

PrecisionDrillTM drilling motors have been used todrill conduit holes to accommodate pipelinescable, and other transmission mediums. Theseholes are generally drilled to traverse obstacles ina proposed right of way which present problemsto conventional trenching methods; river cross-

ings, steep or unstable terrain, shore approaches,or environmentally sensitive areas.

Extraction of water soluble minerals (ie. salt,potash) can be attained through solution mining technologies. In this practice, “paired” wells aredrilled to predetermined targets and water is cir-culated through the holes until communication isestablished. Water is then forced down one holeand allowed to exit through the other with it’s

mineral in solution.

Grout holes can be drilled to stabilize unconsoli-dated formations or isolate water bearing forma-tions. Proper placement and control will result inreduced overall costs and greater technical effi-ciencies for the procedure.

Methane and water drainage holes have beencommon in the mining industry for years. Similartechniques are being employed in the environ-mental industry for in situ evacuation of toxic con-taminants left in industrial and waste disposalsites.

5.0 PRECISIONDRILLTM

MUD LUBRICATEDDRILLING MOTOR OPERATION

In order to get the best performance and opti-mum life of PrecisionDrillTM mud lubricated drilling motors, the following standard procedures shouldbe followed during operation. Slight variationsmay be required with changes in drilling condi-

tions and drilling equipment, but attempts shouldbe made to follow these procedures as closely aspossible.

5.1 ASSEMBLY PROCEDURE AND SURFACECHECK PRIOR TO RUNNING IN HOLE

Although all PrecisionDrillTM mud lubricateddrilling motors are shipped from the shop thor-

oughly inspected and tested, some initial checksshould be completed prior to running in hole.These surface check procedures should only beused with mud drilling systems.

CAUTION:To avoid potential bit, motor, and BOPdamage, these preliminary checksshould be completed without a bitattached. A thread protector should be

installed in the bit box whenever moving the motor, but must be removed beforeflow testing.



March 2005 17

(1) The correct lift sub must always be installedand used for moving the tool on or off the rig floor, and for lifting the tool into position formake-up. Also be sure the connectionbetween the lift sub and the drilling motor istight. To lift the drilling motor to the rig floor,use a tugger line secured around the lift sub.Pick up the PrecisionDrillTM drilling motor with

the elevators and set it into the slips of therotary table. Install the dog collar / safetyclamps.

NOTE: The lift sub supplied with the drilling motor should only be used for lifting thedrilling motor. The capacity of the liftsub is restricted to the weight of thedrilling motor and should not be usedfor any other purpose.

NOTE: Only apply rig tongs on the identifiedareas of the drilling motor. All connec-tions of the drilling motor are torqued inPrecision Energy Services’ service shop.Further make-up on the rig floor is notnecessary, and if attempted may causedamage.

(2) Remove the lift sub and connect the kelly tothe drilling motor, remove the dog collar /safety clamp, and lift the drilling motor out of the slips. Remove the thread protector fromthe bit box and inspect the threads fordamage.

(3) Lower the drilling motor until the top end isbelow the rotary table. If the drilling motor hasa dump sub, position it so the dump sub ports

are still visible below the rotary table.CAUTION:The dump sub valve will remain open

until there is enough fluid pressure toclose it. Therefore, the drilling motorshould be lowered until the ports arebelow the rotary table. This will preventthe initial flow of drilling fluid from spray-ing on the rig floor.

(4) Slowly start the pumps. Ensure drilling fluid isflowing out of the dump sub ports, if applicable. Increase the flow rate until thedump sub ports close, and drilling fluid stopsflowing out. Make note of the circulation rateand standpipe pressure.

CAUTION:Do not exceed the maximum recom-mended flow rate for this test.

(5) Lift the drilling motor until the bit boxbecomes visible. It should be rotating at aslow, constant speed. Listen to the bearing section of the drilling motor for excessivebearing noise, especially if the tool has beenused previously without being serviced. Inaddition, ensure that a portion of drilling fluidis coming out of the motor directly above the

bit box. Five to ten percent of the total flowcirculating through this point is acceptable.



First Edition18

(6) If the drilling motor has a dump sub assembly,before stopping the pumps, the drilling motorshould be lowered below the rotary table.Ensure that drilling fluid flows out of the dumpsub ports after shutting down the pumps. It ispossible that the dump sub valve may remainclosed after this test due to a pressure lock. If this occurs, no drilling fluid will flow out of the

ports. To remove the pressure lock, bleed off some standpipe pressure and the valve willopen.

CAUTION:The surface check should be as short aspossible; it is merely to ensure that thedrilling motor is rotating.

(7) Once flow has been turned off, the thrustbearing clearance can be checked. First, with

the drilling motor hanging with no weight onbit, a measurement can be made between thebottom-most face of the drilling motorhousings and the top edge of the collar on thebit box. Record this measurement as D1.Similarly, take the same measurement withthe weight of the motor applied on the bit andrecord this value as D2. Subtract D2 from D1to calculate the amount of axial clearance in

the drilling motor. It must not exceed thevalues in Table 6 of Appendix 4.

(8) Radial play in the drilling motor can bechecked by putting a wrench on the bit boxand deflecting it radially - up to 0.040diametrical movement is acceptable.

(9) After this surface check, the bit should beattached to the motor using a bit-breaker,

while holding the bit box stationary with arotary tong. Be sure to avoid contacting theend cap directly above the bit box with thetong dies.

CAUTION:It is recommended that you never holdthe bit box stationary and rotate thedrilling motor counter-clockwise, or holdthe drilling motor stationary and rotate

the bit box clockwise. This could possi-bly cause the internal drilling motor con-nections to back off and damage it.Although rotating in the opposite direc-tion will result in drilling fluid to bepushed out the top end, the internalconnections will not be at risk of discon-necting.

(10) If the drilling motor has been used previously,an overall inspection should be completed.General visual inspection of the entire drilling motor should be carried out to check formissing oil plugs, housing damage, or looseconnections. Ensure that a “LaydownRequirements Review” (Appendix 4, or L3-COM-CA-MOT-F0051) has been completedand all limitations have been taken intoaccount. If limitations have been exceeded asdescribed on the form, the drilling motorshould not be re-run.



March 2005 19

(11) Set the adjustable assembly to the desiredbend. The instructions for this procedure canbe found in the Appendix of this handbook. Acopy is also attached to each motor before itis sent out from the service shop. The torquerequired on the adjustable assembly is alsoindicated in the motor specifications.

(12) If a float sub is used, it should be placedimmediately above the drilling motor.

5.2 TRIPPING IN HOLE

Generally, a drill string with a PrecisionDrillTM

drilling motor can be run into the hole like a stan-dard bottom hole assembly. The drilling motor isrugged, but care should be taken to control travel

speed while tripping into the hole. The drill string should be tripped with the blocks unlocked andspecial care must be taken when passing theB.O.P., casing shoe, liner hanger, bridges, andwhen nearing bottom. Tight spots should be tra-versed by starting the pumps and slowly reaming the drilling motor through. When reaming, the drillstring should be periodically rotated to preventsidetracking.

When tripping to extreme depths, or when holetemperatures are high, periodic stops are recom-mended to break circulation. This prevents bitplugging and aids in cooling the drilling motor,preventing high temperature damage.

Fluid should not be circulated through a drilling motor inside casing if a PDC or diamond bit isbeing used, as this may damage the bit cutters.

If a dump sub assembly is not used and the pipeis not being filled while tripping in, the back pres-sure on the power section will cause the rotor toturn in reverse. This could cause internal connec-tions of the drilling motor to unscrew.

CAUTION: Stop and break circulation beforeputting drilling motor on-bottom. Failureto do so could plug jets and/or damage

the drilling motor.

5.3 DRILLING

When the assembly has been tripped to the bot-tom of the hole, PrecisionDrillTM drilling motorsshould be operated in the following manner:

(1) With the bit 1-2 meters (3-6 feet) off bottom,

start the pumps and slowly increase the flowrate to that desired for drilling. Do not exceedthe maximum rated flow rate for thePrecisionDrillTM drilling motor.

(2) Make a note of the flow rate and the totalpump pressure. Note that the pressure mayexceed the calculated off bottom pressuredue to some side load effects between the bit

and the hole diameter.



First Edition20

(3) After a short cleaning interval, lower the bitcarefully to bottom and slowly increase theweight. Note that torque can be affected by adirty, uncirculated hole and the hole should beadequately cleaned prior to orienting the tool.Fill may be cleaned out of the well bore byslowly rotating the drilling motor or by staging the drilling motor full circle 30° to 45° at a

time. This prevents ledge buildup and sidetracking.

(4) Orient the drill string as desired and slowlyapply further weight onto the bit. Pumppressure will rise as the weight on bit isincreased. Note the change in systempressure between the off bottom and onbottom values. This will be the differentialpressure. Try to drill with steady pumppressure by keeping a steady flow rate andconstant weight on bit.

NOTE: Adding weight on bit will cause both thedifferential pressure and torque toincrease. Similarly, reducing weight onbit will reduce both the differential pres-sure and the torque. Therefore, the rig pressure gauge enables the operator to

monitor how the drilling motor is per-forming, as does the weight on bit indi-cator.

CAUTION:Applying excessive weight on bit maycause damage to the thrust bearings.Similarly, applying excessive tensionwhile stuck may cause damage to thethrust bearings. Please refer to the

specifications for the recommendedmaximum loads for these conditions.

CAUTION:Do not exceed the maximum recom-mended differential pressure as listedin the specifications. Failure to do socould result in premature wear or dam-age to the drilling motor stator.

NOTE: Optimum differential pressure can be

determined by monitoring motor per-formance, penetration rate, and drilling requirements. Also, maintaining a con-stant weight on bit and differential pres-sure assists in controlling orientation of the drill string.

5.4 REACTIVE TORQUE

A PrecisionDrillTM drilling motor drives the bit witha right-hand (clockwise) rotation. As weight isadded to the bit, reactive torque acting on thedrilling motor housing is developed. This left-hand(counter-clockwise) torque is transferred to thedrill string and may cause the joints above themotor to tighten. Reactions of this type increasewith larger weight on bit values and reach a max-imum when the motor stalls. This reactive torque

also affects the orientation of the motor when it isused in directional drilling applications.Therefore, this reactive torque must be taken intoaccount when orienting the drilling motor fromthe surface in the desired direction.



March 2005 21

5.5 DRILLING MOTOR STALL

Stalling usually occurs when the application of excessive weight on bit or hole sloughing stopsthe bit from rotating, and the power section of thedrilling motor is not capable of providing enoughtorque to power through. This is indicated by asudden sharp increase in pump pressure. This

pressure increase is developed because the rotoris no longer able to rotate inside the stator, form-ing a long seal between the two. If circulation iscontinued, the drilling fluid forces it’s way throughthe power section by deflecting the stator rubber.Drilling fluid will still circulate through the motorbut the bit will not turn. Operating in this state willerode and possibly chunk the stator in a veryshort period of time, resulting in extensive dam-

age. It is very important to avoid this operating condition.

When stalling occurs, corrective action must betaken immediately. Any rotary application shouldbe stopped, and built up drill string torquereleased. Then the weight on bit can be reducedallowing the drill bit to come loose and the drilling motor to turn freely. If the pump pressure is stillhigh, the pumps should then be turned off. Once

again, failure to do this will result in the statoreroding until the drilling motor is inoperable.

5.6 BIT CONDITIONS

The bit speeds developed when drilling with adrilling motor are normally higher than in conven-tional rotary drilling. This application tends to

accelerate bit wear. When drilling with a drilling motor and simultaneously rotating the drill string,it is important to avoid locking up the bit and overrunning the drilling motor with the rotary table. Alocked bit will impart a sudden torque increase inthe drilling motor which can be detected by a sud-den sharp increase in standpipe pressure. If thisoccurs, disengage the rotary table and reduce theflow rate. Backlash may occur from reactive

torque distributed in the drill string as describedin the section above. Failure to react in this situa-tion may cause drilling motor damage.

5.7 ROTATING THE DRILLING MOTOR

For directional control, it is sometimes necessaryto rotate a drilling motor that has the adjustableassembly set for a deviation angle. Rotating the

drilling motor set at excessive bends may fatiguethe housings of the drilling motor to a point wherea fatigue crack is initiated, and fracture occurs oroverload the radial bearing support and createexcessive bearing wear. Therefore, PrecisionEnergy Services has provided maximum dogleg limits for rotary drilling based on the bend angle,hole size, and stabilization. These limits are pro-vided in tables within the motor specifications.

These limits are based on maximum rotaryspeeds of 60 RPM. For higher speed rotary limits,please contact your Precision Energy Servicesrepresentative.



First Edition22

5.8 TRIPPING OUT

Prior to tripping out when drilling with convention-al mud, it is recommended that the fluid be circu-lated for at least one “bottoms-up” time to ensurethat the well-bore has been cleaned thoroughly.

The tripping out procedures for a PrecisionDrillTM

drilling motor are basically the same as those for

tripping in. Taking care when pulling the drilling motor through tight spots, liner hangers, casing,casing shoes, and the B.O.P. is necessary to min-imize possible damage to both the drilling motorand the wellhead components. Rotating may alsobe done to assist with the removal of the drillstring. The dump sub valve will allow the drillstring to be emptied automatically when tripping.

Although the drill string will drain when tripping out, the drilling motor itself may not. Once thedrilling motor is at surface, rotating the bit box ina counter-clockwise direction will naturally drainthe drilling motor through the top. This is recom-mended before laying down a PrecisionDrillTM

drilling motor since aggressive drilling fluids candeteriorate the elastomer stator and seals. Freshwater should also be flushed through to ensure

thorough cleaning of the drilling motor. Also, cleanthe bit box area with clean water and install athread protector into the box connection.

NOTE: Rotating the bit box in a clockwise direc-tion will naturally drain the drilling motorthrough the bottom, but one of theinternal connections may break andunscrew. For this reason, it is not rec-ommended to rotate it in this manner.

5.9 SURFACE CHECKS AFTER RUNNING IN HOLE

Before laying down a PrecisionDrillTM mud lubri-cated drilling motor, it should be inspected in theevent that it is required again before servicing -essentially, the inspection procedures followed inSection 5.1 can be repeated, with attention paid

to dump sub functionality, bit box rotation, fluidbypass rate above the bit box, and axial and radi-al movement of the bottom end of the drilling motor. If there are any concerns with the drilling motor, it should be laid down for servicing.

In addition, a mud lubricated drilling motorLaydown Requirements review should be per-formed in case the drilling motor is going to be re-run. This review (Appendix 4 or L3-COM-CA-MOT-F0051) takes into account any environment thedrilling motor has been run in and evaluates therisks involved with its usage. This form is availablefrom your Precision Energy Services representa-tive.



March 2005 23

6.0 DRILLING FLUIDS

The PrecisionDrillTM drilling motor is designed tooperate effectively with practically all types of drilling fluids. Successful runs have beenachieved with fresh or salt water, with oil basedfluids, with additives for viscosity control or lost

circulation, and with nitrogen gas. However, someconsideration should be taken when selecting adrilling fluid, as elastomer components of thedrilling motor are susceptible to premature wearwhen exposed to certain fluids.

Hydrocarbon based drilling fluids can be veryharmful to elastomers. A measure of this aggres-siveness is called the Aniline Point, which is thetemperature at which equal amounts of thehydrocarbon and aniline become miscible. Thistemperature is an indication of the percent of light ends (aromatics) present in the hydrocarbon.It is recommended that the aniline point of anydrilling fluid not be lower than 94.5°C (200°F).Also, it is strongly recommended that the operat-ing temperature of the fluid be lower than the ani-line point. Operating outside these parameterstends to excessively swell elastomers and causepremature wear, thus reducing motor perform-ance. The use of stators that compensate forelastomer swelling in hydrocarbon-based fluids isrecommended. These special order drilling motors may be requested with sufficient notice.For any information regarding availability or deliv-ery, please contact your Precision EnergyServices representative.

Drilling fluids with high chloride content cancause significant damage to internal compo-nents. When these components become dam-aged, the drilling motor’s performance is dramat-ically reduced.

Typical lost circulation materials such as calciumcarbonates, walnut shells, cellophane flakes andcellulose fiber (among others) can be used safely

with PrecisionDrill

TM

mud lubricated drilling motors. However, a few considerations must bemade when doing so. Generally, the particle sizeshould be no greater than 1/8” for 4-3/4” and 5”drilling motors, and 1/4” for 6-1/4” and largerdrilling motors. Larger particle sizes will have atendency to start plugging up port nozzles in thedrilling motor and lead to circulation problems.For the same reason, the mud density should also

be no greater than 19 lbs/gallon. Finally, in orderto ensure avoiding plugging of the system, thelost circulation material should be added slowly,away from the pump intake. A pre-mix systemwould be the preferred means of usage. If thereare any concerns in regard to these values,please contact your Precision Energy Servicesrepresentative.



First Edition24

The percentage of solids should be kept to a min-imum. Large amounts of abrasive solids in thedrilling fluid will drastically increase the wear on astator. It is recommended that the solids contentbe kept below 5% for acceptable operational life.Similarly, it is recommended that fine abrasivessuch as sand be kept lower than 0.5% as they areextremely damaging to the stator elastomer.

For the above reasons, it is extremely importantto flush the drilling motor with fresh water beforelaying it down, especially when working with thetypes of drilling fluids previously described.Failure to do so will allow the drilling fluid to fur-ther seriously deteriorate components long afterthe drilling motor has been operated.

7.0 TEMPERATURE LIMITS

The temperature limits of PrecisionDrillTM drilling motors again depend on the effect of different flu-ids and temperatures on the components madeof elastomers. Generally, standard drilling motorsare rated for temperatures up to 105°C (219°F).

At temperatures above this, the performancecharacteristics of elastomers are changed, result-ing in reduced life expectancy. When exposed tohigher temperatures, the elastomers swell andcreate more interference than desired, wearing the parts out prematurely. The strength of theelastomers is also affected.

To compensate for these elastomer changes, spe-cial materials and special sizes of componentsare used. These unique drilling motors are specif-ically assembled for high temperatures, and maybe operated in temperatures up to 150°C(300°F) and higher. They may be requested withsufficient notice. For any information regarding availability or delivery, please contact yourPrecision Energy Services representative.

It should be noted that a PrecisionDrillTM drilling

motor manufactured for hot hole conditions willnot perform as indicated in these specificationsin lower temperatures. The rubber in the stator isspecially selected for more clearance at highertemperatures to minimize interference.Therefore, at lower temperatures, the stator elas-tomer will not seal adequately on the rotor, andfluid bypass will occur. It is important that thedrilling motor be used in the conditions it is

designed for in order to operate as required.

8.0 TROUBLESHOOTING DOWNHOLE

Careful attention to variations in fluid pressurecan identify many common downhole problems.In many cases, corrective measures may save acostly trip. Following are symptoms that are some-times experienced during drilling, in conjunction

with some of their possible causes in reference toPrecisionDrillTM drilling motors. Also listed aremeasures that can be taken to correct the prob-lem and continue drilling.

NOTE: Any time there are problems incurredwhile drilling, it is strongly suggestedthat all possible surface problems areidentified and corrected before assum-ing the problem is related to the down-hole equipment. This will minimize anytrip time for pulling out the downholeequipment unnecessarily.

8.1 WITH BIT OFF BOTTOM

(1) Circulation pressure is lower than calculated.

A. Dump Sub Valve Stuck Open - Turn flow

rate on and off in an attempt to shut thevalve. Use varying flow rates. Also, the drillstring can be stroked one stand long tohelp loosen the valve. If unable to closethe dump sub valve, it may be necessaryto pull out of hole.

B. String Washout - Normal drill string washout procedures apply.

C. Lost Circulation - Normal lost circulationprocedures apply.

(2) Circulation pressure is higher than calculated.

A. Drilling Motor or Bit Plugged - This usuallycoincides with little or no circulation. Onceall hydraulic systems have been checkedand verified, it may be necessary to pullout of hole.

B. Excessive bit side loading due to undergauge hole or high adjustable assemblybend angle - This usually coincides withfull circulation. If the drilling motor is tootight against the wall of the wellbore, thebit may start sidetracking. Correctivemeasures include drilling a kelly down toreduce side loading, or reducing the bend

angle on the drilling motor. If sidetracking is a concern, the drilling motor should berun with a lower flow rate to prevent it.



First Edition26

8.2 WITH BIT ON BOTTOM

(1) Circulation pressure is lower than calculated.

A. Dump Sub Valve Stuck Open - Turn flowrate on and off in an attempt to shut thevalve. Use varying flow rates. Also, the drillstring can be stroked one stand long tohelp loosen the valve. If unable to close

the dump sub valve, it may be necessaryto pull out of hole.

B. String Washout - Normal drill string washout procedures apply.

C. Lost Circulation - Normal lost circulationprocedures apply.

D. Worn or Damaged Stator - With certain

drilling fluids, stators may wear prema-turely, resulting in noticeable weakening over it’s usage. As the stator wears, thespeed of the drilling motor will bereduced. Therefore, indications of a wornstator will be a drop in the ROP, or anincrease in the differential pressurerequired to produce the same ROP.

E. Gas Kick- Normal gas kick proceduresapply.

(2) Circulation pressure is higher than calculated.

A. Drilling Motor or Bit Plugged - This usuallycoincides with little or no circulation.Remove the weight on bit, allow the bit todrill off, and then stop the pumps. If thepressure remains high, it is possible that

the drilling motor or all bit jets areplugged. Once all hydraulic systems havebeen checked and verified, it may be nec-essary to pull out of hole.

B. Excessive bit side loading due to undergauge hole or high adjustable assemblybend angle - This usually coincides withfull circulation. If the drilling motor is tootight against the wall of the wellbore, thedrilling motor may be working too hardand the torque requirement will be greaterthan the recommended value for thedrilling motor size. Corrective measuresinclude reducing weight on bit or reducing the bend angle in the drilling motor.

C. Drilling Motor Stalled or Stalling - Usuallycoincides with pressure increase. Rotary

application should be stopped and anybuilt up string torque slowly released. Theweight on bit can then be reduced allow-ing the drill bit to come loose and thedrilling motor to turn freely. If the pumppressure is still high, the pumps should beturned off. These steps must be followedin close succession to reduce potentialstator damage.

D. Mud Rings - These occur when cuttingsaccumulate around tool joints. They causethe string to stick and prevent sliding. Usestandard mud treatment procedures.



March 2005 27

(3) Change or Loss of rate of penetration.

A. Drilling Motor Stalled - Usually coincideswith pressure increase. Rotary applicationshould be stopped and any built up string torque slowly released. The weight on bitcan then be reduced allowing the drill bitto come loose and the drilling motor toturn freely. If the pump pressure is stillhigh, the pumps should be turned off.These steps must be followed in close suc-cession to reduce potential stator dam-age.

B. Worn Stator - Refer to worn stator infounder ‘Circulation pressure is lower thancalculated’ above.

C. Change of Formation - Adjust the flow rateand weight on bit to optimize drilling per-formance for the new formation condi-tions.

D. Drill String / Stabilizers Hung Up - Normalcorrective procedures apply.

E. Bit Worn or Balling - Normal bit wear orballing procedures apply.

9.0 DRILLING MOTOR SPECIFICATIONS

DIMENSIONAL DATA

Typical dimensions including length to bend, over-all length, length to upsets, as well as maximumouter diameters for various padding arrange-ments. Also included are the wellbore diametersthat the drilling motors are recommended for, topand bottom connection specifications and totalweight.

ESTIMATED BUILD RATESA table is given correlating the adjustable bendsetting and common wellbore diameters for bothslick and fully stabilized drilling motors with anestimated build rate. One Stabilizer refers to aBHA with a single screw-on stabilizer below thebend in the drilling motor. Two stabilizers refers toa BHA with stabilizers below the bend and direct-

ly above the drilling motor. All values are based onstabilizers 1/8” (3mm) undergauge. However, asconditions vary downhole, these estimates maybe inaccurate for some wells. Caution should beused when referring to these values, as experi-ence with certain formations will allow for a moreinformed estimate of the expected build rate. Inaddition, the torque required for the adjustableassembly is given.



First Edition28

MAXIMUM DOGLEG FOR ROTARY DRILLING

This table provides the maximum recommendeddoglegs to rotate in for selected angle settings,hole sizes, and stabilization. Exceeding these val-ues will result in accelerated component fatigueand excessive bearing loading. These limits arebased on a maximum rotary speed limit of 60

RPM.

PERFORMANCE SPECIFICATIONS

Listed here are the performance specifications of the drilling motor, including minimum and maxi-mum flow rate capacities, and no-load RPM / flowunit values. Minimum and maximum bit speed atfull load differential pressure are also stated.

(Full load differential pressure is defined as themaximum differential pressure the drilling motoris capable of operating under with acceptablewear rates and life expectancy.) Also in the speci-fication is the maximum torque capacity that cor-relates with the full load differential pressure of the minimum specified flow rate. The maximumpower is calculated from the maximum bit speedand the maximum torque for the full load differ-

ential pressure for the maximum flow rate speci-fied. Maximum values for torque and power forstandard and premium nitriles are both shown.

The maximum allowable bit pressure drop isgiven. If this value is exceeded, premature wearmay occur to the bearing assembly. Also, the no-load pressure drop on the drilling motor based onwater (at room temperature) being the drilling

fluid and maximum flow rate is given. This valuewill vary when these conditions are different.

LOAD CAPACITIES

The operating load capacities are the maximumloads that can be applied to the drilling motorwhen it is being circulated through, and still allowcontinued use. Similarly, the static load capaci-

ties are the maximum loads that can be appliedwhen the drilling motor is not being circulatedthrough, and still allow continued use. The ulti-mate load factors are the loads that must not beexceeded, otherwise excessive damage will occur.

PERFORMANCE CHARTS

Charts for both metric and imperial units are

shown to provide operational characteristics overthe full range of flow rates and differential pres-sures for the drilling motor. Each chart is actuallytwo charts laid over each other. The two compo-nents of each chart are described below, as wellas instructions in how to read them.



March 2005

RPM

The first component of the chart is the RPM line.Across the bottom of the chart is differential pres-sure (kPa/psi). The differential pressure is the dif-ference between the system pressure when thedrilling motor is on-bottom (loaded) and off-bot-tom (not loaded). On the left side of the chart isthe speed (RPM). These are the scales to be usedwhen using the horizontal RPM lines on the chart.The horizontal lines start at the speed axis of thechart and begin to drop off slightly as differentialpressure increases. They eventually end some-where past the full load lines (vertical lines).These RPM lines are usually laid out as two setsof three lines, each for a different specified flowrate. The specified flow rates can be seen slightlyabove the lines.

The light colored RPM lines are for StandardNitrile Motors and end shortly past the StandardNitrile Full Load line.

The dark colored RPM lines are for PremiumNitrile Motors and end shortly past the PremiumNitrile Full Load line.

The RPM lines are used to determine what the

drilling motor RPM is, knowing what the flow rateand differential pressure are. Using the chart inFigure 4 for a 6 3/4” (171 mm) PrecisionDrillTM

LE6754-ML drilling motor, if the flow rate is 450GPM (1.71 m3 /min) and the differential pressureis 500 psi (3450 kPa), for a standard nitriledrilling motor (light colored RPM line) the speedof the drilling motor would be approximately 117RPM. For flow rates different than the ones given

on the chart, lines can be interpolated betweenthe lines, then the RPM can be read.

The chart shows what happens to the speed of the drilling motor as differential pressure isincreased. For the most part, the drop in RPM asdifferential pressure increases is slight until thefull load line is crossed. At that point the RPMdrops quickly to zero, which is stall mode.

Therefore, it is important to not go beyond themaximum recommended operating differentialpressure, or the drilling motor will be operating inefficiently and wear will occur.

In addition, it can be seen that as differentialpressure is increased, the standard nitrile RPMlines drop off faster than the premium nitrilelines. This indicates that the premium nitrile

drilling motors would hold their RPM better thanstandard nitrile drilling motors.

TORQUE

The second component of the chart is the torqueline. On the right side of the chart is the torquescale (ft-lbs, N-m). The torque line is used withthis scale and the differential pressure scaleacross the bottom. The torque line starts at 0 dif-ferential pressure and 0 torque, and increaseslinearly as differential pressure increases. Thesame torque line is used for the various flow ratesbecause torque is independent of flow rate. Thistorque line is the same for both standard and pre-mium nitrile drilling motors.

The torque output of the drilling motor can bedetermined by knowing the differential pressureacross the drilling motor. Using the chart inFigure 3, if the differential pressure is 500 psi

(3450 kPa), the output torque from the drilling motor is approximately 4800 ft-lbs (6500 N-m).

FULL LOAD

The full load lines indicate the maximum recom-mended operating differential pressures of thedrilling motor. If the differential pressure goesbeyond these maximum values, the operating lifeof the stator will be reduced. Excessive pressure

drop across the rotor and stator will cause pre-mature pressure wash or chunking, and impairperformance.

Premium nitrile is capable of higher pressuredrops than standard nitrile, so the maximumallowable pressure drop across one is more thanthe maximum allowable pressure drop across astandard nitrile drilling motor. As seen in Figure 4,the standard nitrile drilling motor is only rated for

650 psi differential pressure, whereas the premi-um nitrile drilling motor allows 860 psi differentialperssure. This extra differential pressure equatesto an increase in torque output.

Laydown Requirements Review

PURPOSE

The following document is to be used by field per-sonnel to evaluate and document the condition of the mud lubricated drilling motor at surface afterbeing used downhole. It also is used to decidewhether or not a drilling motor should be rerun inthe hole based on a variety of operational condi-tions that it was used under.

The three sections below list the different limita-tions of the PrecisionDrillTM mud lubricated drilling motors:

z Mandatory - in all regions, if any of theselimitations is exceeded, the drilling motor

should be laid down.z Regional Based Limitations - based on the

limitations of each region, if any of theselimitations are exceeded, the drilling motorshould be laid down.

z Cumulative Limitations - exceeding eachlimitation will not require the drilling motor to

be laid down. However, as the number of exceeded limitations increases, the more likelythe drilling motor should be laid down.

The last section is for reference of what therequired measurements of axial movement basedon tool size will be.

1. MANDATORY LIMITATIONSIf yes for any of these, the motor shall be laid downand not be reused.

Appendix #6Rotor By-Pass Nozzle Instructions


All Precision Energy Services M and L selectionsof mud lubricated drilling motors have rotors with

a bore cut through the center to facilitate fluidflow rates greater than the capacity of the powersection. By using a nozzle on this bore, partialfluid flow can pass between the rotor and statorup to the maximum allowable capacity, with theadditional fluid flow going through the rotor.

Rotor By-Pass Nozzle Instructions


159

At start-up, as fluid flow rate is increased, all fluidwill pass through the rotor. The friction between

the rotor and stator will prevent it from rotating.EventuaIIy the pressure drop across the rotor noz-zle will be greater than the pressure drop requiredto overcome the frictional losses between therotor and the stator, and the drilling motor willstart to rotate. If the correct nozzle has beenselected, once the full flow rate is achieved andthe required pressure differential is achieved, thedrilling motor should have a portion of the flow

approximately equal to its maximum specifiedcapacity passing between the rotor and the stator.The remaining portion of the flow will passthrough the rotor. For equilibrium, during all oper-ations, the pressure drop across the rotor andstator wiII be equal to the pressure drop acrossthe rotor nozzle.

Therefore, the drilling motor will operate in the fol-

lowing way. Once full flow rate is achieved, and noweight has been applied to the bit, excess fluidflow will pass between the rotor and stator. Onceweight is applied on the bit, the differential on therotor and stator will be at the value that the noz-zle was sized for, splitting the flow as desired.

Therefore, extra precautions should be observedwhen working with Precision Energy Services mudlubricated drilling motors using rotor-by-pass.Extra care should be taken when not having weight on bit, and the length of time this occursmust be minimized. Failing to do so will causepremature wear and damage to the stator fromexcessive flow.

In order to size a nozzle for a specific situation,three factors are required:

1. Total Required Flow Rate, Qr: This is the totalflow rate of the drilling fluid as required forproper drilling operation.

2. Required Motor Pressure Drop, Pm: Theestimated pressure drop (differentialpressure) of the drilling motor when down-hole.

3. Mud Weight, MW:

Once these factors are known, the requirednozzle size can be selected in the following way. First, the flow rate that is to pass throughthe rotor nozzle Qn is calculated. To determinethis value, subtract the maximum flow ratecapacity of the size and series PrecisionEnergy Services mud lubricated drilling motorto be used from the total required flow rate Qr.



First Edition



The nozzle area required for this operation

can then be calculated using the following for-mula:

The size of nozzle required can then be deter-mined by looking at the enclosed table fornozzle sizes in Appendix 12.

The design of the nozzle assemblies vary forthe different sizes of drilling motors, soinstructions for installing each one aredescribed separately below.
