Introduction PathFinder Drilling Motors (PDM) was estab-lished in April of 1991 with the purpose of sup-plying the oil & gas industry a series of high quality and dependable downhole drill-ing motors on a sales, lease, or rental basis. PDM motors have been a major player in all areas of the world. This manual is provided for informational purposes only. PDM has taken the necessary precautions to ensure its accuracy, but PDM does not expressly or im-plicitly guarantee the information contained herein. The information contained herein is the sole interpretation of the user. Should the user have any questions pertaining to its accu-racy, please contact a PDM representative.
Motor Description
This section of the handbook is designed to provide the drillers and the operators with a general description of our downhole drill-ing motors. Although different size motors have different performance characteristics, they share the same basic components:
• Top Sub • Catch Mandrel • Power Section • Power Transmission Coupling • Fixed or Adjustable Bent Housing • Bearing Pack Assembly • Bit Box • Near-Bit Stabilizers
Figure 1Figure 1 illustrates the major components of our drilling motors.
5
Top Sub & Catch Mandrel
The top sub has a dual function. It is used as a cross over between the motor assembly and the drill string. It also functions as part of the catch system by providing the seat for the catch mandrel.
The Rotor Catch Mandrel is incorporated in the design of PDM motors as a retaining device. Its function is to minimize the possibility of losing motor components in the hole, in the unlikely event that an external connection breaks or backs-off. It is also designed to communicate a possible connection failure to the surface via a series of pressure signals. To recognize these signals, it is important to understand how the Rotor Catch Mandrel behaves under normal and distressed conditions.
The Catch Mandrel is attached to the top of the rotor by a threaded connection. The fl ow channels around the mandrel are sized to minimize the pressure losses across the catch mechanism. The upset section of the catch is positioned inside a cavity within the Top Sub. This cavity provides the seat for the catch if or when an external motor connection fails. Under normal operating conditions, the catch simply rotates with the rotor without any substantial load being applied to it. Figure (2) illustrates the catch under normal operating conditions.
6
Figure (3) shows the catch position after a
connection failure. There are two basic modes
of connection failure: connection breakage
and connection back-off. The catch behaves
differently under each condition. If an exter-
nal motor connection is severed, with motor
on-bottom, a sudden loss of pressure occurs.
Picking the motor off-bottom will seat the catch
resulting in off-bottom pressure increase. The
increase in pressure can range from a few
hundred psi to several hundred psi, depend-
ing on the fl ow rate and mud properties. As
soon as the motor is set on bottom, the catch
will unseat itself and relief the pressure. This
pressure fl uctuation is indicative of a possible
connection failure.
If the mode of failure is connection backoff,
two scenarios are possible. If the connection
separates completely, the pressure signal will
be as described before. If the catch seats it-
self before the joint is totally separated, then
setting the motor on-bottom will not unseat
the catch. The rotation of the drill string might
screw the connection back together and re-
lieve the excessive pressure.

Power Section
The power section uses what is known in the in-dustry as Positive Displacement power section. Its function is to convert a portion of the hydraulic energy of the drilling fl uid into mechanical horse-power. The components comprising the power section are the rotor and the stator. The rotor is a long and spiral shaft, designed to fi t inside a corresponding stator. It is manufactured from a solid bar of stainless steel and plated with hard industrial chrome or tungsten carbide. The chrome or tungsten carbide is intended to protect the parent metal against corrosion and wear while reducing the friction between the rotor and the stator. In high-fl ow applications, PDM rotors can be jetted to divert the additional fl ow to the bit.
The stator is the non-rotating member of the power section. It is made out of a seamless, heat-treated tube, lined with an elastomer (rubber) lin-ing. The internal cavity of the liner has a spiral geometry designed to accept a rotor of compat-ible geometry and size. In a Positive Displacement power section, the rotor always has one less lobe than the stator.
Power sections are categorized by their size, rotor/stator lobe ratios, and the number of stages (stage in a power section is defi ned as the dis-tance, measured parallel to the rotor axis, be-tween two corresponding points of the same spiral lobe, i.e. lead length of the spiral).
9
Figure (4) shows the cross-sectional view of the rotor and the stator profi le with different lobe ra-tios. There are a few rules of thumb, which might be benefi cial in the selection and operation of any PDM motor:
1-The rotational speed of the rotor is proportional to the rate of fl uid fl ow through the power sec-tion.
2-The generated torque is proportional to the dif-ferential pressure across the power section.
3-The torque generated is independent of the fl uid fl ow through the power section.
4-Power sections with a higher lobe ratio typically generate more torque and have slower rotary speed than the ones with a lower lobe ratio. For example, a 9 5/8” motor with 3:4 lobe ratio will rotate the drill bit at a higher RPM and will have less output torque per stage than a 9 5/8” motor with 4:5 lobe ratio.
5-An increase in the number of stages will propor-tionally increase the output power and torque at the same fl ow rate.

Optimum completion of a drilling project relies heavily on the proper selection of the stator elas-tomer compound. The main factors to consider are the maximum downhole temperature, mud type, mud additives, and any harmful chemi-cals which might be encountered during drilling. Given enough forewarning, testing of the drill-ing fl uid under simulated downhole conditions can be conducted before the drilling tools are assembled. Test results are helpful to determine the optimum elastomer for the application.
As mentioned in earlier sections, PDM offers several different stator elastomer compounds. These different compounds react differently when exposed to elevated temperatures and the various chemicals present in drilling fl uids.
The standard elastomer is a nitrile based rubber NBR suitable for use with water based and low temperature oil based drilling fl uids. This rubber is suitable for use in wells with temperatures in excess of 270ºF with the proper sizing and fl uid compatibility. The standard nitrile stators are the most common and cost effective option for most drilling conditions. An additional nitrile elastomer is available in certain models which is more rigid and resilient. This NBR-HR™ elasto-mer can deliver a minimum of 50% more power than the standard NBR with the proper drilling parameters.
11
In drilling applications where the drilling fl uid is less typical and the temperature is elevated, the highly saturated nitrile elastomer HSN may be the optimum choice. The highly saturated type elastomer is formulated for greater chemical re-sistance, especially at higher temperature. HSN elastomer is the best suited elastomer for oil based and most synthetic based drilling fl uids.
Some motor sizes have the option of a metal re-inforced or uniform elastomer thickness stator equipped power section. The uniform or even elastomer stator compared to a conventional stator can be seen below in Figure (5).
The metal reinforcement of the elastomer pro-fi le provides a structural reinforcement of the elastomer profi le allowing its seal against the rotor to operate at signifi cantly higher pres-sure differential than conventional stators. This higher pressure differential produces a higher operating and stall torque. The higher pressure seal between the rotor and the stator assures a more steady speed operation than a conven-tional power section. 12
Figure 5
The metal reinforcement also provides a superior path for heat dissipation from therotor and stator interface. This superior heat dissipation allows the metal reinforced stator to operate more reliably at elevated tempera-tures than a conventional power section. The smaller elastomer content of the metal reinforced stator also provides for a stator more resistant to aggressive oil and synthetic based drilling fl uids.
Power Transmission Coupling
The power transmission coupling is the link between the rotor and the Bearing Mandrel. It converts the eccentric motion of the rotor into the concentric rotary motion of the Bearing Mandrel or Driveshaft. It also transmits the torque and the rotary motion of the rotor, generated by the power section, to the bearing assembly. The hydraulic down thrust of the rotor is also transferred to the bearing section through this member. All PDM Power Transmission Couplings are manufactured from a high grade of heat treated alloy steel. The working surfaces of the power transmis-sion are sealed with a high temperature and pressure lubricant to assure optimum opera-tion and reliability.
Bent Housing
The fi xed or adjustable bent housings con-tain the Power Transmission Coupling and connects the stator housing to the bearing
13
housing. Bent housings are available with fi xed and adjustable bends. Fixed bent hous-ings can only be confi gured at PDM’ facilities in angles ranging from 0 to 5 degrees depend-ing on the motor model. The adjustable hous-ings can be set to various bend angles at the rig site (see the appendix section of this hand-book for adjustment procedure). The mag-nitude of the Adjustable Bent Housing bend angle ranges from 0 to 3 degrees. This bend of the Fixed or Adjustable Bent Housing gives the motor its steering capability. The Fixed and Adjustable Bent Housings are manufac-tured out of premium grade high strength alloy steel. Their contact surfaces with the formation are hard-faced to minimize wear while drilling.
Bearing Pack Assembly
The bearing pack assembly contains the neces-sary components to transmit the rotary drilling motion to the drill bit and transmit the drilling forces from the Bottom Hole Assembly (BHA) to the drill bit. The main components of the Bearing Pack Assembly are the Bearing Mandrel or Driveshaft, Thrust and Radial Bearings. The Bearing Mandrel or Driveshaft is a bored, long shaft designed to transmit the power (torque and rpm) to the drill bit. It also channels the drilling fl uid to the bit. It is manufactured out of a high grade of alloy steel that is forged and heat-treated for strength and toughness. The Thrust Bearings are designed to sustain
14
the applied weight to the drill bit while on-bottom. They are also capable of bearing the downward hydraulic thrust load of the rotor The Thrust Bearings are designed to sustain the ap-plied weight to the drill bit while on-bottom. They are also capable of bearing the downward hydraulic thrust load of the rotor while circulat-ing off-bottom or drilling with under balanced bit weight. Depending on the motor model the thrust bearings may consist of a unique tool steel ball bearing design that is precision made and enables the same set of bearings to carry the on-bottom as well as the off-bottom load. This important feature increases the number of bearing races within the limited available space and increases the thrust load capacity and the life of the bearing pack. An alternative Thrust Bearing design utilized in some models consists of high grade Polycrystalline Diamond Compact (PDC) Inserts similar to those used on PDC Drill Bits. These PDC inserts provide a high capacity and extremely wear resistant thrust bearing for applications where shorter tool length or extra longevity is required.
The Radial Bearings rigidly support the bearing mandrel inside the bearing housing and transfer the radial forces generated during drilling to the housings and the rest of the BHA, while assur-ing that the Driveshaft is aligned and concen-tric with the axis of the bearing housing.
15
The Radial Bearings are constructed from spe-cialized Tungsten Carbide components to pro-vide optimum life and reliability.
The design of the Tungsten Carbide radial bear-ings also precisely meter the amount of drilling fl uid that fl ows through the radial and thrust bearings for cooling of the bearings. This as-sures the optimum drilling fl uid fl ow through the driveshaft and out to the drill bit.
The Bearing Pack Assembly of the PathFinder Motor is one of the few designs that also incor-porates a Driveshaft safety catch feature to mini-mize the possibility of leaving the drill bit in the hole in the unlikely event the Driveshaft breaks or backs-off. Figure 6 illustrates the normal run-ning position of the Driveshaft and the Driveshaft Catch on the left and the engaged position of the Catch on the right. If the Driveshaft breaks or backs-off a precision low stress upset or ridge on the lower portion of the Driveshaft engages

a split ring contained within the lower portion of the bearing housing preventing the Driveshaft from exiting the bearing pack. A substantial decrease in the off bottom pressure drop on the surface will signal an incident has occurred so that appropriate action can be taken.
Bit Box
The bit box is an integral part of the bearing mandrel. Its outside diameter is sized to ac-cept a specifi ed box connection. While all the external components of the motor are station-ary relative to the drill string, the bit box is the only external component which has a rotary motion independent of the rotational speed of the drill string. The drill bit is screwed directly into the bit box.
Near-bit Stabilizers
Near-bit Stabilizers are available with remov-able or integral stabilizers. The removable sta-bilizers are screwed on the bearing housing. Occasionally certain clients wish to have the option of installing different stabilizers on the motor at the rig site to alter the directional per-formance of the motor. In that case, the motor and the stabilizer(s) can be shipped separately and a protective sleeve protects the external threads of the bearing housing.
17
Motor Application
In today’s cost-conscious oil and gas environ-ment, companies and operators recognize the positive contributions downhole drilling motors can make to their bottom-line. The application of downhole drilling motors are no longer limited to conventional drilling, but has expanded to other areas such as:
• Steerable Drilling • Medium & Long Radius Drilling • Re-entry Drilling • Horizontal Drilling • Performance Drilling • Hole Opening • Hole Spudding • Conductor Pipe Drill Downs • Underreaming & Casing Cutting • Milling • Coring
PathFinder Drilling Motors offers a wide vari-ety of motor confi gurations, bit speeds, fl ow ranges, and power outputs to suit your par-ticular need. Our state-of-the-art drill motor is designed to exceed the load capacity of any available drill bit in the industry today.
18
PLANNING THE JOB
To maximize the benefits of using drilling motors, it is essential to select the right motor for your specific application. To do so, the following factors should be considered: Hole Size Different size PDM motors are designed to function effectively within a certain size hole. The “Motor Specifi cation” section of this hand-book has outlined the recommended hole sizes for each motor size. We encourage the drillers and the planners to adhere to these recom-mendations, since any deviation might result in hole problems and /or cause a premature motor failure.
Build-Rate Capability Choose the proper motor bend angle to generate the desired build/drop rates without exceeding the maximum allowable DLS.
The logistical use of the stabilizer(s), in a straight or bent motor, can also help you stay on track. The technical staff at PathFinder Drilling Motors can assist you with your selec-tion, through the use of computer modeling and software. Bit Selection The proper selection of the drill bit can substantially increase the penetration rate, reduce the drilling cost, and improve the motor performance.
19
The bit TFA (Total Flow Area) has a great deal of infl uence on motor performance, as well as the ability to clean the hole. An undersized bit TFA will result in high pressure drop across the bit and lower than expected fl ow rate. In-adequate fl ow rate can result in overheating and damaging the bit, hole cleaning problems, and will starve the motor of the adequate fl uid needed to operate at its optimum performance. On the other hand, oversized TFA might not be able to provide the fl uid momentum neces-sary to properly remove the cuttings. In the “Formulas” section of this handbook, neces-sary formulas are provided to calculate the bit TFA. In the “Motor Specifi cation” section of this handbook, the recommended bit pressure drop is listed for each size motor. If the fl ow requirements needed for your specifi c appli-cation exceed the maximum allowable motor fl ow rate, a bored rotor can be provided to supply the additional fl uid.
For angle building runs, the gage length of the bit becomes very important. High drag, aggressive PDC bits exert more stress on the motor components than the cone bits or less aggressive bits. Also, high RPM motors com-bined with high WOB require more fl ow to cool the bit (contact the bit manufacturer for the minimum recommended bit fl ow rate).
20
Drilling Fluid
The most fl uid sensitive component of the PDM motor is its stator rubber lining. The PDM mud motors can operate successful-ly with any water-based mud, fresh water, brine, sea water, any oil-based mud with aminimum of 200°F aniline point and less than 2% aromatic content. The pH level of the drilling fl uid can affect the life of the drilling motor. The recommended pH level for PDM motors are between 9 and 10.
If the mud pH level and/or aniline point are very close or slightly outside the specifi ed lim-its, continuous circulation of the drilling fl uid minimizes the extent of the damage to the motor. If there is a prolonged interruption in drilling, periodic circulation through the motor might increase the motor life, since the stag-nation of harmful fl uid inside the motor will deteriorate it in an accelerated rate.
The solid contents of the drilling fl uid should be maintained below 5% and the sand con-tents below 1%. Any deviation from the speci-fi ed limits will cause the stator elastomer lining
21
to wear rapidly, which will result in a gradual reduction in the output power of the motor.
Mud weight is another factor, which should be considered when planning the drilling opera-tion. Generally speaking, heavier mud (12 lb/gal. or more) will wear the motor at a faster rate than a lighter mud. When using a heavy drilling fl uid, keep the sand contents below 0.5% to prevent possible washing in the drill-ing motor.
Any additives to the mud system should be carefully selected to comply with these speci-fi cations. If a substantial amount of gas or air is trapped in the drilling fl uid, it should be removed to prevent any possible damage to the stator rubber lining.
Medium to fi ne lost-circulation material can be used, as long as they are mixed thoroughly. If the drilling conditions require the use of coarse material, we recommend the use of jet subs above the motor to bypass a portion of the
22
particles and prevent the plugging of the mo-tor. The use of solid additives with a rough or sharp texture should be avoided, since they might scar or cut the stator rubber lining.
Hole Temperature
One of the factors, which affects the physical and mechanical properties of the stator elasto-mer lining, is the operating bottom hole temperature. An increase in temperature decreases the mechanical strength of the stator rubber lining and causes it to swell. The swelling will consequently increase the rotor/stator interference. The excessive inter-ference will increase the frictional heat genera-tion and will over stress the rubber compound, resulting in premature stator failure.
PathFinder alters the interference fi t between the rotor and the stator to compensate for the anticipated downhole temperature. Communi-cating the expected downhole temperature is critical to a successful motor run.
23
Figure (7) illustrates the reduction in the tensile strength of the nitrile elastomer as the temperature increases.
To increase the motor life, certain cautionary measures should be employed when drilling in a hot hole environment. These measures are addressed in the “Motor Operation” section of the handbook.

Rotor Nozzle Usage With the exception of high-speed power sec-tions (1:2 lobe ratio) most PDM rotors can be bored to accept various size nozzles. Rotor nozzles are used to increase the fl ow rate to the bit by bypassing a portion of the fl uid through the rotor. The use of a rotor nozzle is recommended where the system hydrau-lics mandates a fl ow rate, which exceeds the maximum allowable fl ow through the motor. Please consult your PDM representative to determine if the use of a rotor nozzle is appropriate for your application. As a refer-ence please refer to the “Nozzle Selection” section of this handbook, for an indication of the proper sizing of the rotor nozzle. Power Requirements When selecting a motor, close attention should be paid to the power output of the motor. The motor should be powerful enough to deliver the required amount of torque, at the right RPM, to turn the drill bit in response to the application of various WOB.
Power is the measure of the rate at which torque can be applied and is a function of both torque and rpm. The concept of power and torque can be combined by saying that torque is used to overcome the ro-tational resistance provided by the formation, while power is needed to increase the rate of 25
penetration. When choosing a motor based on performance, the questions to ask should be, “Can the motor produce enough torque for the application?” if it can, the next question should be, “Which motor can apply the most power to the formation? If the goal is to increase ROP, the most powerful motor should be selected.
Most motors are available with Standard and Performance Power Sections. A Performance Motor can substantially increase the ROP, de-crease stalling, and drill harsh formations with more ease than a standard one. Stator Rubber Compound Selection
Optimum completion of a drilling project relies heavily on the proper selection of the stator rubber compound. The main factors to con-sider are the maximum hole temperature, the mud type and its additives, and the type of harmful chemicals, which might be encoun-tered during drilling.
PathFinder offers several different stator rub-ber compounds. All compounds swell due to increase in temperature but behave differently when exposed to chemical attack.
Standard Nitrile (NBR) and NBR-HR are our most widely used compounds. They
26
are nitrile-based elastomers, which are suitable for use with most water-based and oil-based drilling fl uids and additives. The physical and mechanical properties of NBR and NBR-HR de-grade the most when exposed to high tem-perature and high chemical concentrations. Highly Saturated Nitrile (HSN) is designed to operate with oil-based or synthetic drilling fl u-ids. The use of this compound is not recom-mended with water-based mud. With proper rotor and stator interference a stator, lined with HSN compound, can operate at bottom hole temperatures of up to 325°F. Compared to Standard Nitrile, it retains more of its physi-cal and mechanical properties. Given the same described drilling conditions, the HSN is de-signed to outlast and outperform NBR.
The Mud Treatment/Cleaning System
As previously noted, chemistry of the drilling fl uid as well as its weight and texture are cru-cial to the life and performance of PDM motors. On certain wells, the properties and/or chemi-cal composition of the mud are continuously changing. The changes are either intentional, due to the operational demands, or unintention-al because of the geological factors. Therefore continuous monitoring of the drilling fl uid and a competent mud treatment and cleaning sys-tem are necessary to maintain the properties of the drilling fl uid at its desired level. 27
LCM – Lost Circulation Material (LCM) should be used in limited amounts and should be thoroughly mixed and added to the drilling fl uid. The addition of large slugs of LCM has the potential to plug the motor and damage its internal components. LCM should be limited to fi ne to medium sized particles.
Abrasive media – Sand content in the drilling fl uid should be kept to a minimum and ide-ally below 1%. This is especially important if the motor is operated at the upper end of its fl ow range. Where possible the use of hema-tite weighting materials should be avoided as these have shown to be unusually prone to damaging the internal motor components.
Failure to follow the preceding recommenda-tions can result in:
• Rapid deterioration of the power section and subsequent decline in the power output. • Expeditious wear of the power transmis- sion components, i.e. Flexible Coupling and Bearing Pack. • Washing of the fl ow channels and weak- ening of critical components, especially in high-fl ow application. • Plugging of the motor. • Seizure of the Bearing Pack.
28
A suffi cient mud treatment system should be capable of continuously monitoring and adjusting the PH level of the mud to desired range (9< PH < 10 ). It should do the same to maintain the aniline point of the oil-based mud within the desired level (minimum of 200°F and less than 2% aromatic content).
Infiltration / accumulation of substantialamounts of gaseous matters in the drilling fl uid pose a problem to the motor and should be contended with.
When drilling for gas or encountering gas pockets, all or a portion of the gas molecules gets imbedded in the drilling fl uid. Depending on the relative properties of the mud and the gas, some of the gas accumulates inside the mud, while the remaining amount escapes the mud voluntarily. When the gas bubbles are pumped back into the well, the hydrostatic pressure of the well bore gradually forces the gas into the stator rubber compound through its microscopic pores. The gas-impregnated rubber sustains permanent and irreversible structural damage, which degrades the elasto-mer’s properties. An adequate mud treatment system should promptly recognize and combat the problem by extracting the trapped gases.
29
MOTOR OPERATION
This section of the handbook provides a gen-eral guideline regarding the use of PDM drill-ing motors. PDM downhole motors arrive at the rig site with all the internal and external connections made up to the specifi ed torque. The near-bit stabilizer, if ordered, is installed and made-up to its full recommended torque value. The bit box and top sub connections, specifi ed by the customer, are fi tted with thread protec-tors. Once the drill bit is installed, the motor is ready for operation.
Rig-Site Motor Test
Prior to running the motor into the hole, the motor should be tested while on the surface. The test can be performed with the bit at-tached, unless there might be a possibility of the bit dragging on the internal walls of the test area. In that case the motor should be tested without the bit.
Remove the Top Sub and Bit Box thread pro-tectors. Using the provided lift-sub, pick the motor up and set it in the slips. Install any available safety clamp and proceed to remove the lift-sub. Attach the kelly to the motor and remove the safety clamp. Lower the motor in-side the hole until the gap between the top of the bit box and the bearing housing is be-low the drilling nipple. Start the pumps and
30
gradually bring the GPM up to the desired lim-it. Make a note of the fl ow rate and the system pressure. It might prove to be benefi cial to in-crease the fl ow rate in several increments and note the standpipe pressure in every case. The motor vibrates vigorously at higher fl ow rates. This is one of the characteristics of the posi-tive displacement motors and should not be a cause for concern. The test is considered sat-isfactory if there are not any substantial fl ow and pressure fl uctuations.
Also note that a portion of the drilling fl uid has been discharged through the bottom of the Bearing Housing and has drenched the Bit Box. This is absolutely normal, since a small percentage of the drilling fl uid is diverted through the Bearing Pack to lubricate and cool the bearings. Aligning The Steering Device
A narrow and shallow line called the scribe-line marks the bend plane of PDM motors. This line is located on the Fixed or Adjustable Bent Housing and is used to indicate the tool face. Tripping In
If the motor is equipped with a fi xed or adjustable bend housing (below the sta-tor) and/or a bent sub (above the Top Sub), exercise extreme caution when
31
passing through the BOP, casing shoe, liner hangers, ledges, or key seats. If the circulat-ing hole temperature is more than 220°F, initi-ate circulation periodically to cool the stator rubber lining. Pumping should be at a slow rate and should last long enough to allow the cooler fl uid to reach the power section. If a fl oat valve is not used and the drill string is empty, the annulus pressure combined with the dynamic pressure, generated by piercing through the fl uid, will force the drilling fl uid through the bit and into the motor, causing the motor to rotate in reverse. This could result in unscrewing one or more internal components. Therefore it is our recommendation to use at least one fl oat valve in the bottom hole assem-bly. If the use of a fl oat valve is not feasible, keep the drill string full at all times and trip in slowly. Keep the running speed low when deal-ing with heavy mud and small liners.
Take pressure readings at three or four fl ow rates close to operating fl ow rates when trip-ping in. This data can be used as a reference to conduct similar tests following any drilling problems.
Drilling With PDM Motor
Regardless of the application, certain common procedures should be followed to ensure a successful motor run. This section is designed to outline certain guidelines to
32
assist the end users of PDM motors with their drilling challenges. After reaching the bottom of the hole, with the bit “off-bottom”, start the pump and slowly in-crease the fl ow rate to the desired level (See the “Motor Specifi cation” section of the hand-book for the recommended motor GPM). Once the circulation is established, record the stand-pipe pressure reading. This pressure will be higher than the one recorded on the surface. Gradually lower the motor to the bottom of the hole and apply weight to the bit. This will increase the motor power output, which will cause an increase in the standpipe pressure. Continue to add weight until the desired RPM at certain GPM is achieved (see “Motor Specifi -cation” section for RPM values). Record the “on - bottom “ pressure. The difference between the “on-bottom” and “off-bottom” pressure is called the differential pressure. As the motor drills off, continue to add weight to maintain the desired differential pressure.
The performance curves at the “Motor Specifi -cation” section of the handbook shows that the motor RPM decreases as the differential pres-sure of the motor approaches its full-load limit. Since ROP is directly related to the motor RPM, operating the motor at its full-load might not
33
show any substantial increase in ROP, but it will defi nitely reduce the stator life. Therefore, for the best results keep the differential pres-sure at about 75% of its maximum recom-mended value. If the motor is overloaded or is not allowed to drill-off the applied weight, a rapid increase in standpipe pressure will occur. At this point the motor is at its “stall” pressure, which means the bit is not rotating and the fl uid is passing between the rotor and the stator without turn-ing the rotor. Repeated stalling of the motor could result in premature motor failure. When stalling happens, stop the rotary table imme-diately and cutback the GPM by at least 50% before lifting the motor up.
When tagging the bottom of the hole for the fi rst time, or after changing the bit or the bend angle, drill with lightweight for about 30 minutes to create a bit pattern at the bottom of the hole. Failing to do so could result in repeated stalling and subsequent stator dam-age. If drilling in an environment where the cir-culating bottom-hole temperature exceeds 200°F, certain precautionary measures should be considered. As mentioned earlier, the me-chanical strength of the stator rubber lining is reduced substantially at elevated temperatures. To reduce the magnitude of the stress on the 34
rubber, limit the differential pressure across the motor to 70% of its full-load value. A prolonged interruption in drilling results in additional swell-ing of the stator rubber. When bringing the pumps up, start gradually at low GPM to allow the stator rubber to cool. Increase the fl ow rate to the desired level at several increments. Cir-culate off-bottom long enough to let the cooler fl uid reach the motor. Lower the bit to the bot-tom slowly and resume drilling.
The use of performance motors in hot-hole en-vironment can also improve the life of the mo-tor, since due to additional power-generating stages; the differential pressure per stage will be less than a standard power section. Adding lubricants to the drilling fl uid and keeping the mud clean could also improve the stator life by reducing the friction between the rotor and the stator and decreasing the frictional heat.
Rotary RPM
During the drilling operation, it is a common practice to rotate the drill string at a moderate RPM. While rotating, a lateral force is exerted on the drill bit by the formation. The magnitude of the force is directly proportional to the bend length, bend angle and formation hardness and is inversely proportional to the hole size. The induced bending stress on the motor raises con-cern about the possibility of fatigue failure. 35
Fatigue failure will happen in a fi nite number of bending cycles, if the magnitude of the bending stress exceeds the fatigue endurance limit of the metal. Under these conditions the rotary speed plays a signifi cant role in the suc-cessful completion of the well. A high rotary RPM can substantially accelerate the genera-tion and growth of fatigue cracks under severe bending forces.
We have experienced the least number of mo-tor problems, when the rotary speed and bend angle are limited to 50 RPM and 1.50° respec-tively. So, to avoid a catastrophic connection failure, we strongly urge you to adhere to these limitations.
Jarring
When selecting a jar for a particular drilling operation, avoid using one whose maximum pull capacity exceeds the maximum allowable pull for the motor, as listed in the “Motor Spec-ifi cation” section of this handbook. Replace the motor, if it has been jarred for more than three times.
Tripping Out Of the Hole (Re-running)
When pulling a bent assembly, exercise ex-treme caution at the tight spots such as BOP, casing shoe, ledges, etc. Once on the surface, fl ush the tool with clean water by placing a water hose into the top sub and rotating the bit box in the clockwise direction until the dis-charge is clear. If the bit box is locked-up, lay the motor down. 36
Checking the Motor For Re-Run
If the previous run was relatively short and the motor had not been exposed to a harsh environment such as high hole temperature, oil-base mud, sour gas, jarring, or any other extreme condition, then a decision can be made regarding the reuse of the motor. To do so, the integrity of the power transmis-sion components, i.e. the radial bearings and thrust bearings and power transmission coupling, should be confi rmed. -Radial Bearing: with the motor hanging se-curely from the kelly, rotate the bit box in both directions for at least four complete revolu-tions. If the rotation indicates a tight spot in the bearing, lay the motor down. Also check the radial play of the bearing by shaking the bit box from side to side. The design of radial bearing allows for a small amount of radial play. Do not reuse the motor if the play is ex-cessive.
-Thrust Bearings: measure the thrust bearing wear as followed (Figure 8). With the motor hanging securely, record the bit box/bearing housing gap (dimension “A”). Stand the mo-tor on the rig fl oor and apply moderate axial force. Measure and record the same gap (di-mension “ B “ ). If the clearance (A-B) exceeds the allowable limits, as outlined in the following table, the motor is not suit-able for rerun.

MOTOR SPECIFICATION
This section of the handbook provides critical information regarding the physical characteris-tics and performance parameters of PDM drill-ing motors. PDM is continuously improving its motors and procedures. Therefore, the information in this section can change without prior notice. All the changes will be refl ected in the latest revision of the handbook or subsequent PDM brochures and literature. The fl ow rate, RPM, torque, differential pres-sure correlation is presented graphically for each motor. The proper interpretation of these graphs is crucial in maintaining the specifi ed operating limits of the motor. Interpreting Performance Graphs
The performance characteristics of every PDM motor are presented by the performance graphs. These graphs show the output torque and speed of the motor, each at different fl ow rates versus the differential pressure across the motor.
The characteristics of a motor can be sub di-vided into two different categories, indepen-dent and dependent. The independent charac-teristics are the ones, which can be controlled by the driller (i.e. differential pressure and fl ow rate). The dependent characteristics are those,
43
which are inherent in the design of the motor and its power section (i.e. RPM, torque, horse-power, and effi ciency).
To determine the dependent characteristics of a motor, locate the desired differential pres-sure on the corresponding axes. Draw a per-pendicular line until it intersects the curve rep-resenting a particular dependent characteristic at a certain GPM (the output torque is not a function of the motor GPM). From the point of intersection, draw a horizontal line to intersect the desired vertical axis. For example, the following curve shows that at 300 psi of differential pressure and 200 GPM, the approximate speed and torque of this particular motor are 96 rpm and 1560 ft-lbs respectively.

F2000 Adjustable Bend Connecting Rod Housing
The Adjustable unit is located as an integral part of the F2000 motor between the upper connection on the Bearing Housing and lower connection of the Stator unit. Its construction is made up of three main external components, i.e. Upper Sub, Sliding Spacing Sleeve, and the Lower Sub. By orienting the central connection within the sliding spacer sleeve the bend angle of the sub can be varied from 0° - 2.30°.
This procedure is applicable through the various product sizes, i.e. 4 3/4” to 9 5/8” as the basic design is similar throughout.

Rig Floor Setup:
Use the break out tong to both break and make up the connection. The make up tong should be fi xed to a dead-line. Use an Ezy torque if available, if not, load cell on the deadline needs to be fi tted. Ideally, both should be used to cross-check torque calibrations.
Rig Floor Operational Procedure:
1. Set the motor in the slips around the bearing housing area so the sliding spacer sleeve is at a convenient working height.
2. Latch the make Up Tong to the lower sub, clear of the Sliding Spacer Sleeve connection to prevent crimping the internal connection. For 4 3/4” and 6 3/4” tools, four inches below the shoulder. For all other sizes, fi ve inches below the shoulder.
3. Latch the Break Out Tong midway over the Sliding Spacer Sleeve and the Upper Sub.

4. Break the central connection a full half turn.
5. Remove the Rig Tongs from the assembly.
6. Inspect the Sliding Spacer Sleeve and make sure that the shoulder of the sleeve has separated between the spacer sleeve and the upper housing. It may be necessary to lightly tap the sleeve with a soft hammer to free it from the internal keys.
7. Fix a chain tong to the Slider Spacer Sleeve and rotate the same as required to align the setting mark on the Sliding Spacer Sleeve with the adja- cent Bend Angle Setting Marks.
• When carrying out this procedure Do not allow the setting mark on the Sliding Spacer Sleeve to rotate out with the Lower or Upper limit of the Bend Angle Setting Marks. • Rotation of the Sliding Spacer Sleeve will also be aided by supporting the weight of the assembly above the connection by the travelling block i.e. fl oating the weight of the tool in the slips. If this option is used a safety clamp/dog collar should be fi tted directly above the slips. • If diffi culties are encountered on rotating the Sliding Spacer Sleeve on 9 5/8” assemblies with chain tongs, rig tongs may be used. The application of this however must be made to limit the applied breakout torque on the connection to +15,000 ft-lbs. Fitting of the tongs must be also carefully controlled to prevent crushing the assembly or damaging the tools integrity i.e. with the lower tong being placed over the Lower Sub/Sliding Spacer sleeve and the upper tong placement 10” above the sealing shoulder of the Upper Sub/Spacer Sleeve.
8. Latch the make up tong across the connection between the upper sub and the spacer sleeve. Using either the rotary table or a chain tong (with manual handling considerations today the chain tong may not be an option) rotate the lower sub until it shoulders tightly into the spacer sleeve. Unless the make up tong has caused a standoff then the upper connection on the spacer sleeve should also be shouldered tightly. • Do not allow the Sliding Spacer Sleeve to rotate at this time, as the bend orientation will be changed. 9. Re-latch the Rig Tongs as per fi gure 4, i.e. fi t the Make Up Tong so it is mid-way over the Sliding Spacer Sleeve and the Upper Sub. The Break Out Tong can then be fi tted to the Lower Sub maintaining the same minimum clearance as in Step 2.Figure (3): ABH Sliding Spacer Sleeve Adjustment

10. Apply the relevant make-up torque to the connection. (See below) When the make-up torque is reached hold the line pull at 90° for 10 seconds.

11. As a fi nal check, unlatch the make up tong and move it up onto the upper sub and re-latch. Re-apply the full torque across both connections simultaneously. • If there is little or no movement then this confi rms that the full torque has been applied across both connections and there has not been any standoff between the spacer sleeve and the upper sub.

12. Remove the rig tongs and inspect the assembly to ascertain that the orientation of the Setting Mark on the Sliding Spacer Sleeve is correctly aligned with the Bend Angle Setting Marks as per requirements. 13. Upon completion of the re-adjustment of the assembly, the corresponding tool face alignment must be re-confi rmed with the relevant MWD orientation marker. To fulfi ll this requirement the Tool Face Scribe Lines on the Adjustable Housing Top Sub must be used. These can be seen in Figure (3) and are the uppermost set of fi gures on the assembly.
• Do not use the Bend Angle Settings Marks for the orientation of the PDM with the MWD. This will result in the orientation of these being +90-180° in error with the corresponding possible catastrophic course direction problems.
Operational Notes:
• On every trip out of the hole always re-check the Make Up Torque on the Adjustable Assembly prior to re-running the same. • At no time should the Rig Tongs be placed on any other adjacent connection of the F2000 motor as these connections are not rig serviceable.
• Be aware of any rig instrumentation errors in the control of the Make Up Torque, i.e. broken gauges, leaking tong sensors, etc. This is due to the applied Make Up Torque and the Adjust able Assembly being critical to its overall performance.
• If rig tongs are utilized to aid in the orientation of the Sliding Spacer Sleeve, be aware of the possible mis-application and the infl uence this could have over the integrity of the assembly.

NOZZLE SELECTION
For proper sizing of the nozzle, from the “Motor Specifi cation” section of this handbook, obtain the recommended fl ow rate through the mo-tor at the desired RPM and differential pres-sure. Subtract this fl ow rate from the total de-sired fl ow rate to obtain the required fl ow rate through the nozzle (q). Adjust the fl ow rate for the actual mud weight as follows:
Using Q and desired motor differential pressure, look up the nozzel size from the chart below. Use the next smaller nozzle if between sizes.
Q = q x .35 x (Mud Weight) (gpm) (gpm) (lb/gal)

NOZZLE SELECTION EXAMPLE
A 6 ¾”, 4:5, 7.0 stage motor is used to drill a well. A 12.5 lb/gal mud at 750 GPM will be used to complete this well. If the motor is operated at 700 psi of differential pressure, determine if it is necessary to nozzle the rotor? If so, what is the proper nozzle size?
SOLUTION
The maximum allowable flow rate through a 6 ¾”, 4:5, 7.0 stage motor is 600 GPM, as listed in the “motor Specifi cation” section of this hand-book. Therefore the additional 150 GPM should bypass the power section through the rotor.
To determine the nozzle size, fi rst adjust the fl ow rate for the actual mud weight:
Q = 150 x .35 x (12.5)5 = 185.62 GPMThe chart on the previous page shows that to pump 185.62 gallons at 700 psi differential pres-sure requires a 16/32 nozzle.
