5. STRUCTURE ANDDELIVERY COMPLETENESS5.1. The motor includes a power section and a spindle section interconnected by sub. Torque and axial hydraulic load is transmitted from an eccentric (planetary) rotating rotor to the spindle section by means of a hinged device.

5.2. The motor scope of supply includes:

a motor, 1 pc.•data sheet, 1 pc.•

5.3. Sets of spare and replacement parts, tools and accessories for maintenance and repair of the PDM are available on individual request of the customer.

6. DESIGNAND OPERATION6.1. Downhole motors relates to machines of volumetric (hydrostatic) action, which allows to implement the drilling process realizing a high torquetogether with low rotational speed of the output shaft.

6.2. Control over the motor operation can be performed by pressure changing in the delivery line since the pressure drop across the motor is in proportion to the torque on its shaft.

6.3. The main units of downhole drilling motor are:

power section [2], spindle section [5], angle adjuster (or a rigid bent sub) [4], propeller shaft [3], top [1] and bottom [6] anti-failure (picking) units (pic. 1).

12

6.4. Power section [2] is designed to convert an energy of the drilling fluid flow into the rotary motion of the rotor and then transmitting this motion to the spindle section shaft. The motor section includes a rotor and a stator. The stator is formed as a steel casing, the inner surface of which is vulcanised with rubber lining with the inner helical teeth of a left direction. A steel rotor is having outer helical teeth whose number is one less than that of the stator. The teeth of the stator and the rotor form lengthwise-isolated closed-circuit chambers. Drilling fluid injected by mud pumps of the rig comes to the bit and turns the rotor inside the stator sheath.

6.5. Spindle section [5] is designed for the perception of the axial and radial loads of the motor, and includes multi-row thrust radial ball bearing or a multi-row rubber heel and radial sliding or rolling bearings.

6.6. Angle adjuster [4] (or a rigid bent sub) is intended to give the motor a required skew angle. Angle adjuster consists of two subs, a core and a gear coupling, which is reinforced with hard alloy inserts and hard alloy overlaying welding material for improving the wear resistance in contact with the borehole wall.

6.7. Propeller shaft [3] serves to transmit the planetary rotation of an eccentrically disposed rotor to the spindle section shaft.

6.8. Top anti-failure (picking) unit [1] designed to retrieve the motor parts which have been left in the borehole in case of breakage of its body parts. The device includes a top picker sub located above the motor stator,

PERMNEFTEMASHREMONT

a stud screwed in the upper end of the rotor, washer placed on the stud hexagon and a nut, clamping the washer screwed on the stud. In case of breakage of any housing parts weight of the motor parts below the breakage place would be assumed consecutively on the spindle shaft, hinge, rotor, stud, washer, nut and the end of the picking sub.

6.9. Bottom anti-failure (picking) unit [6] intended for removal from the borehole the shaft of the motor in case of its breakage.

• 30-100% motors energy characteristics increaseand significant penetration rate increase.

• Use shorter motors providing energycharacteristics and penetration rate complyingwith standard motors. While directional drilling itallows to increase the intensity and stability ofcurvature parameters growth and decreasebreakdowns number related to the PDM bodymalfunctions.

• Operate mud motors in case of lowered drilling fluid flow rate under conditions of fluid loss or/and limited mud pumps performance.

• Operate screw downhole motors with any corebarrels with core recovery of at least 90%.

9. HYBRID PDMHybrid PDM (pic. 4) — are motors that have a spindle section of a larger diameter than a power section, for example 240/195, 195/172, 172/165, 127/120, 106/95, etc.).

Hybrid PDM provide the following operational advantages:

• Possibility to operate the PDM at lower drillingfluid flow rate, which allows to drill using limitedefficiency mud pumps and save the drilling fluidunder fluid loss conditions.

• Improved load capacity and spindle sectiondurability, longer PDM overhaul period.

1. FACTORS AFFECTINGTHE CHOICE OF A PDM FOR SPECIFIC OPERATING CONDITIONSWhen choosing the type and version of PDM please evaluate geological, technical and technological conditions of a particular well. To ensure reliable motor operation and to obtain the best technical and economic parameters inter alia you must consider the following factors:

1.1. Conditions required for borehole curvature design parameters achievement:

• wells deviation intencity dependent onPDMs the skew angle,

• necessity of centralizers and calibrators use,

• the need for drilling with simultaneous drillstring rotation.

1.2. Bottom hole assembly borehole patency at PDM screw angle set.

1.3. Diameter and drill bit armour type.

1.4. Maximum permissible axial load on the bit.

1.5. The BHA temperature to determine the range of tightness in the toothing of the PDM power section (rotor-stator).

НЕОБХОДИМЫЕ ДЛЯ ПРАВИЛЬНОЙ ЭКСПЛУАТАЦИИ ВЗД

17

Information, required for proper PDM operation

During PDM operation of the PDM tightness in the power section engagement increases due to self-heating and swelling of the rubber cover of the stator and by increasing of the temperature at the bottom hole.

Please note that substantial tightness increase in the power section engagement leads to a reduction of the the rotor and stator resource due to increased wear.

For motors with a regular stator elastomer maximum permissible dynamic bottomhole temperature is 100°C. For motors with a heat-resistant elastomer based on hydrogenated nitrile-butadiene rubber maximum permissible dynamic bottomhole temperature is 250°C.

WARNING! WELL TEMPERATURE RANGE IN WHICH YOU ARE GOING TO OPERATE THE MOTOR SHOULD BE SPECIFIED IN THE PDM SUPPLY APPLICATION FORM.

1.6. Drilling fluid flow rate required to ensure the efficientmotor operation

During the PDM operation please do not exceed the recommended fluid flow upper limit because this leads to increased wear of the power section.

1.7. The degree of the drilling fluid purification.

Heightened sand or other abrasive particles content (over 1%) in a drilling fluid leads to a more rapid deterioration of the power section and support units of the spindle section.

18

PERMNEFTEMASHREMONT

1.8. The composition of a drilling fluid

Downhole mud motors manufactured by Permneftemashremont JSC designed to operate with drilling fluids that meet the following requirements:

* when the density of the drilling fluid is increased please use a motorwith a power section of a special engagement parameters working(on request).

** for drilling fluid with higher chloride ions content it is necessary to use a power section with a specially coated rotor (on request).

*** higher content of petroleum products requires the use the stator elastomer with improved resistance to hydrocarbons (on request).

WARNING! CHLORIDE IONS AND PETROLEUM PRODUCTS CONTENT FOR THE DRILLING FLUID IN WHICH YOU ARE GOING TO OPERATE THE MOTOR SHOULD BE SPECIFIED IN THE PDM SUPPLY APPLICATION FORM.

In order to optimize the choice of the PDM it is recommended to provide the samples of the drillin fluid for analysis.

PERMNEFTEMASHREMONT

To eliminate the mechanical damage of the PDM housing parts carrying out the bottom hole assembly must be made using an elevator and a clamp installed in the groove of the top sub of the motor. If the groove at the top sub is missing the assembly should be performed using an elevator and a spider.

WARNING! NOT PERMITTED:

• taking the stator of the power section or the spindlesection housing with any mechanical wrenches,

• installing the motor into the drilling rig rotor by crimpingthe stator by pneumatic slips wedges,

• screw and unscrew the connection threads of theBHA elements by rotary table rotation while thestator is crimped by pneumatic slips wedges,

• enfold the housing parts in the coupling zone of thethread by any mechanical wrenches.

ATTENTION!The PDM assembly key on the rig must be equippedwith a torque meter. In case of torque meterabsence any claims related to the lapel or brokenconnecting PDM threads will not be considered.

2.6. To exclude motor sludging, oil, gas or water blowouts through drill pipes it is recommended to include a check valve into the BHA (Appendix 3), which should be installed directly above the motor.

2.7. In order to ensure filling and emptying of the drill string by drilling fluid it is recommended to include an overflow valve into the BHA (Appendix 2). In case of absence of the overflow valve as a part of the BHA during round trip operations the column must be refilled by drilling fluid every 200 meters of pipes descent.

2.8. To prevent the ingress of any foreign object into the motor it is recommended to include in the BHA

23


a filter with holes of a diameter not exceeding 5 mm, or slits of a width not exceeding 5 mm and a length not exceeding 100 mm. The filter is recommended to be installed inside the latest drill pipe before kelly or before the top drive.

2.9. Setting the required skew angle of the motor should be carried out in accordance with Annex 1 of this manual Due to the extreme operating conditions of the PDM when drilling directional wells, horizontal sections, cutting out windows in casings or sidetracking operations the skew angle of the motor could differ, then there could be a discrepancy between the actual skew angle of the motor and values tagged on the angle adjuster or hard bent sub.

2.10. Before descending into the well a test run of the motor should be performed.

2.11. The maximum allowable pressures at which the motor must be started (without drillbit pressure drop) are shown in Table №4.

2.12. WARNING! WITH AN AIR TEMPERATURE BELOW 0 °CTHE LAUNCH OF THE MOTOR SHALL BEPRECEDED BY WARMING UP.

Warming up options:

• Close the motor on pipe rack or trough by arubberized fabric (drilling shelter), move the steamconducting gun to the outer surface of the motor,perform warming up for 30-40 minutes.

Installing the steam conducting gun into the top sub or into the shaft of the spindle is STRICTLY PROHIBITED!

• In case of the presence a bathtubs formed vesselon the rig heat the water by steam to 70-100°Сthen warm up the motor in vessel for 1,5-2 hours.

After warming up:

• at temperatures above -15°С – test the motor atthe wellhead: in order to do this the drilling fluidmust be topped up, immerse the motor into thewell so that the spindle section was in the drillingfluid, start the motor.

• at temperatures below -15°С – test the motor inthe well: immerse the motor into the well to adepth of 100-150 m, withstand for 50-60 minutes,start the motor.

2.13. During the test run of the motor it is recommended to test the overflow valve (if available): when feeding the fluid into the motor the valve should close without subsequent leakage of the drilling fluid into the side openings of the valve body; when turning off the fluid circulation valve must open.

25


3. OPERATION METHOD3.1. During the descent of the drill string slacking-off the motor exceeding the maximum allowable axial load is forbidden.

3.2. To avoid clogging of the motor by drill cuttings approaching the well bottom is forbidden if the drilling fluid circulation is switched-off.

3.3. It is forbidden to start the motor by hitting the bottom.

3.4. Bedding of the new bit should be carried-out with decreased axial load in accordance with the manufacturer's recommendations.

3.5. An important difference between the characteristics of screw motors and turbodrills - the dependency between the motor pressure drop and torque at the bit and respectively the axial load. Therefore, loading of the bit must necessarily cause an increase in pressure drop.

If the pressure drop does not increase when loading the bit to the bottom, then the whole or a substantial part of the load is not applied to the bit, but extinguished on the walls of the well. Therefore the lack of deepening is not indicative of the motor failure.

3.6. To select the efficient mode of the motor is necessary to:

• start the motor above the bottom and note thepressure value at idle speed,

• after touching the bottom gradually increase the bitweight to obtain the necessary rate of penetrationand note the value of the operating pressure (underload pressure),

• determine a differential pressure drop (the differencebetween pressure when motor idling and pressureunder load).

26

PERMNEFTEMASHREMONT

For the most efficient motor operation it is recommended to provide constant differential pressure drop, which is proportional to the torque on the bit. If operating by the chosen mode causes while drilling discharge line pressure surges it is necessary to reduce the weight on bit to the values providing stable motor load.

3.7. During the drilling process prevent the emergence of resonance phenomena, in casre of excessive vibrations of the drill string is necessary to change the weight on the bit.

3.8. When the motor breaking there is a sudden increase in pressure in the discharge line. To prevent rupture of the reliaf valve diaphragm of the mud pump is necessary to reduce the axial load on the bit.

3.9. When the motor is stopped to avoid an uncontrolled release of reactive torque accumulated in the drill string, which can cause damage to the BHA or unscrewing of the motor connections, it is forbidden to raise the bit above the bottom during drilling. In this case before lifting the bit immediately stop the rotation of the drill string, stop the mud pumps (and if it is not possible, minimize drilling fluid stream) and using a rotary machine brake device slowly release the torque accumulated in the drill string.

3.10. CAUTION! OPERATING IN EXCESSOF THE MAXIMUM ALLOWABLE DIFFERENTIAL PRESSURE DROP OR WITH PERIODIC STOPS OT THE MOTOR LEADS TO A DRASTIC REDUCTION OF THE PDM LIFETIME.

27


3.11. If after turning off and turning on of the mud pumps the pressure doesn't return to normal, it means that the motor is clogged by drill cuttings or broken and must be brought to the surface to be replaced.

3.12. During the drilling process, do not exceed the maximum allowable drill string rotation speed, which depends on the skew angle set on the motor.

3.13. After bringing the motor out of the well it must be drained from any drilling fluid residues and rinsed with water.

Thereafter, fill the top sub of the motor with 8-10 liters of oil and rotate the spindle section shaft clockwise (looking downwards) until the oil will start to go over the outer surface of the shaft.

4. CRITERIA FOR SENDINGA PDM FOR REPAIRThe motor should be sent for repair in following cases:

4.1. Upon reaching the time to repair, recommended by the product data sheet.

In case of complication of working conditions, for example high content of abrasive particles in the drilling fluid, high level of vibration, etc., recommended operating time should be reduced.

4.2. If during motor operation there are pressure surges in the discharge line which do not relate to the technological factors: pressure rise when detaching from the the bottom or pressure decrease when loading the bit to the bottom.

In this case, there is a motor failure arising from any integrity damage of the body parts.

28

PERMNEFTEMASHREMONT

CAUTION! FURTHER OPERATION OF THE MOTOR IS FORBIDDEN. THE MOTOR MUST BE IMMEDIATELY BROUGHT TO THE SURFACE.

4.3. If the axial play of the output shaft exceeds the permissible value (Table №2).

4.4. After carrying out emergency operations:acid baths usage, lifting the tools with a tensile load effort exceeding the maximum allowable tensile load or maximum allowable torque at body parts.

WARNING! IN CASES SPECIFIED IN PARAGRAPH 4.4. THE MOTOR MUST BE REVISED WITH COMPULSORY FLAW DETECTION OF ALL BODY PARTS AND SPINDLE SECTION SHAFT.

If during emergency lifting operations the motor was subjected to a tensile load exceeding the admissible maximum value, the motor must be decomissioned independently of operating time.

4.5. The motor, which is out of order, must be delivered for inspection and repair to a specialized service facility. Any motor repairs on the rig are prohibited.

5. POSSIBLE MALFUNCTIONSAND CORRECTIVE SOLUTIONS

29


The list of possible PDM malfunctions and their solutions is presented in table №5.

The following does not indicate a malfunction of the motor:

• crossflow of the drilling fluid through the motor withoutrotation of the shaft (due to the gap in power sectionengagement),

• free rotation of the spindle section shaft after lifting themotor out of the well with the proviso that there wasdeepening while drilling (due to the gap in power sectionengagement),

• lack of free rotation of the spindle section shaft(due to the negative allowance in power sectionengagement),

• leakage of the drilling fluid between the shaft and thebody of the spindle section in volume up to 25%.

* For motors equipped with an upper picking unit.** If the BHA included an overflow (excess flow) valve.

Table № 5. Possible malfunctions of a PDMand their solutions

Characterof malfunction

Reason of malfunction

Solution

at the rig at service facility

Discharge line pressure rise during in-well motor operation;

the pressure doesn't drop when detaching

the bit from the bottom

Foreign objects inside the motor

Recommendations are designed for rato of penetration of 6 meters per hour. At a lower rate of penetration proportionaly decrease the speed.

Fatigue failure may be due to a very strong vibration. As required, depending on local conditions, reduce the speed.

Speed depends on the borehole diameter.For smaller borehole diameters limiting speed, respectively, will be less.

«Transition sector» means the distance from the end of the curved portion to the point after which it is possible to increase the speed to a value recommended for the straight portion.

By agreement with customer motors can be made with other skew angles*

• Recommendations are designed for rato of penetration of 6 meters per hour. At a lower rate of penetration proportionaly decrease the speed.

• Fatigue failure may be due to a very strong vibration. As required, depending on local conditions, reduce the speed.

• Speed depends on the borehole diameter.For smaller borehole diameters limiting speed, respectively, will be less.

• «Transition sector» means the distance from the end of the curved portion to the point after which it is possible to increase the speed to a value recommended for the straight portion.
