8 www.micon-drilling.de phone +49.5144.493671 Positive displacement motor (PDM) The positive displacement motors (PDM) of MICON Downhole-Tools GmbH apply the reverse pumping principle first established by Rene Moineau. A circulating drilling fluid is pumped through the positive displacement motor, converting the hydraulic power of the fluid into mechanical power to drive the drill bit independently of drill string rotation. There is a direct proportionality between the flow rate and the speed of the PDM. An increase of the flow rate leads to an increase of rotational speed of the PDM. Similarly, there is a direct proportionality between the torque on the drill bit and the differential pressure drop across the PDM. The monitoring of differential pressure and flow rate at the drill rig provides reliable information about the current torque and speed of the bit. The PDMs are equipped with an adjustable bend housing (ABH), which allows to set the PDM to a certain angle. The PDMs are driven in two modes: Sliding (without string rotation) In sliding mode, the PDM drills without string rotation. The bend housing on the PDM points constantly in the same direction. The rotating bit is continuously deflected from the borehole axis in that direction, which causes the bit to follow a curve. The radius of the curve is affected by the ABH angle. Rotary (with string rotation) In rotary mode the drill string, inclusive PDM, is rotating. The adjustable bend housing of the PDM is also rotating in the borehole. The PDM drills nearly a straight hole. By combining straight and curve sections, any desired bore path can be realized. Sliding Mode - curvature drilling Rotary Mode - straight drilling Stand 02/15 The MICON Downhole-Tools positive displacement motors (PDM) are available in sizes from 3 3/4" up to 9 5/8" and in lobe configuration ranging from 4/5 to 9/10. Upon customers inquiry the customers manufacturing of PDM larger sizes are possible. The power sections are available in standard design and equidistant design. Equidistant stator design allows a nearly double pressure drop across the power section, consequently generating the double torque and output power in comparison to the standard design. Considering the positive displacement motor from top connection to bit connection, the main components of the PDM are top sub, catch sub, power section, adjustable bend housing (ABH), and bearing assembly. These components will be explained more explicitly on the following pages.

9 Components of positive displacement motor (PDM) A brief description of PDM main components: Top sub The top sub is across over PDM between the PDM and the drill string. Catch sub assembly To secure inner and outer components of the PDM in case of any damage to the outer components of the PDM, according to the MICON Downhole-Tools standard all PDM are equipped with a catch sub assembly. Power section The power section consists of a stator and a rotor inside. The outer diameter of the rotor is coated with chrome as wear protection. The inside of the stator is covered with a special rubber type, which is rigid enough to withstand abrasion and wear caused by solids in the drilling fluid and furthermore, it is flexible to provide a pressure seal between the rotor and the stator. The contour of elastomer corresponds to the eccentric rotation of the rotor. Due to this shaping of rotor and stator, several sealed chambers between rotary and stator are formed in which the fluid moves over the length of the power section. The stator has one more lobe than the rotor. Increasing the number of lobes results in increased torque and decreased rotational speed. The two available designs of power section are standard design and equidistant design. Standard design The stator steel housing has a cylindrical inner surface, the lobe contour is formed by the elastomer extruded between the housing and a core. The production cost are low, but thickness of the elastomer varies, which limit the pressure drop (and the torque) of the power section. The rotor is usually coated with chrome. Equidistant design The stator housing has the lobe contour and is coated with a uniform layer of elastomer. Production costs are significantly higher than the standard design, but pressure limitation is approximately 1,5-fold higher. The rotor is usually coated with chrome or carbide. Flex shaft To transmit the rotation and torque from the rotor with eccentric movement to the drive shaft, a flexible shaft is required. In some PDM sizes a ball drive shaft is installed. Adjustable bend housing (ABH) The Adjustable Bend Housing (ABH) is located between power section and bearing assembly. It enables the PDM to be set on a desired tilt angle to achieve the predicted build-up-rate for each drilling purpose. Bearing assembly The bearing assembly consists of mud lubricated radial and axial bearing. The radial bearing are tungsten carbide bearings, located at the upper and lower part of the drive shaft. Between the upper and lower radial bearings the thrust roller bearing stack is located to support axial loads (weight on bit). The bearing assembly might be equipped with a stabilizer or protection sleeve on the outside.

10 www.micon-drilling.de phone +49.5144.493671 ABH adjustment Adjustment of a PDM angle is described in the following steps. The figures illustrate how to adjust the angle. Double pin Lock housing Adjusting sleeve Offset housing Adjustable bend housing assembly Step 1: Break out lock housing Mark position with e.g. crayon. Break the lock housing; unscrew the thread until the gap between the shoulders of the lock housing and the adjusting sleeve is approximately 15 mm. Note: While unscrewing the lock housing, the gear tooth system between adjusting sleeve must remain engaged. While breaking the lock housing it may happen that the gear tooth system between offset housing and adjusting sleeve is disengaged. This must be avoided to prepare the thread connection between offset housing and double pin coming loose. Sense of direction for make up Bit Side Step 1: Break out lock housing Bit Side Bit Side Gear teeth location Step 2: Disengage gear tooth system no gap Move the adjusting sleeve in direction to the lock housing, until the gear teeth of the adjusting sleeve are completely disengaged. Stand 02/15 Step 2: disengaging gear tooth system

11 Step 3: Adjusting the ABH angle Mark the designed angle with e.g. crayon. After that, turn the adjusting sleeve to this position, always in the direction which gives the shortest way from old to new position, until the groove on the adjusting sleeve matches the designated angle of the offset housing. Bit Side Step 3: Adjustment of ABH angle Step 4: Engaging gear teeth back to adjusting sleeve Move the adjusting sleeve in direction to the offset housing, until the gear teeth of the adjusting sleeve are completely engaged to the gear teeth of the offset housing. Bit Side Step 4: Engaging gear teeth back to adjusting sleeve Step 5: Make up lock housing Make up the lock housing. Note: Ensure that the gear tooth system does not slip out of engagement while making up adjusting sleeve and offset housing. Check matching after makeup procedure.

12 www.micon-drilling.de phone +49.5144.493671 Performance data and specification Stand 02/15 The tables on the following pages provide an extensive overview of dimensional and operational data for each MICON Downhole-Tools PDM. The first part of the table describes the general specification of the PDM. These are the overall length of the PDM, the length from bit to bend, the weight of the PDM, the recommended bit range for this PDM type, the standard bit connection (in parentheses also the top connection) and the maximal outer diameter of a slick (unstabilized) PDM. The lobe configuration of the downhole PDM is presented, also graphically, in the next section of the table. Information about the flow rate, in which the PDM will run efficiently, can also be found in this section. Flow rate is proportional to the speed of the PDM. An increase of the flow rate leads to an increased speed of the PDM. The speed to flow rate ratio illustrates the rotation speed of the bit when one gallon respectively liter of fluid is pumped through the PDM. The maximum operational parameter of standard elastomer specifies the highest values at which the PDM should be operated. The stated maximum power output is mechanical horsepower at maximum operational differential pressure and maximum flow rate. In the bearing section the operational and maximum loads that a PDM can withstand during regular drilling operation (WOB) and during back reaming (Back-reaming weight) are presented. The maximal static loads present values which might be applied on a PDM when the drill string is not rotating. The PDM can be used for further runs even if such loads have been applied on the PDM over a period of time. The following maximum static loads are defined: Bit overpull (maximum static) Maximum load through the inner components of the PDM when the bit is stuck in the hole. These calculations are based on static conditions; on the non-rotating drill string. The PDM can be used for further runs if the maximum bit overpull was not exceeded. Body overpull (maximum static) Maximum load on the outer components of the PDM when the PDM is stuck in the hole. These calculations are based on static conditions; on the non-rotating drill string. The PDM can be used for further runs if the maximum bit overpull was not exceeded. Set down weight (max. static) Maximum load, which can be applied on a PDM when it is placed on the bottom of the hole.these calculations are based on static conditions; on the non-rotating drill string. If the maximum static loads have been exceeded, up to the parameters specified on the ultimate loads section, the PDM cannot be used for further operations. The PDM cannot be operated during the time that any of these loads are applied. Plastic deformation and damage to PDM components may occur in this loads area. If these loads are achieved, the PDM has to be sent back to the MICON Downhole-Tools GmbH for maintenance. If the loads on the components exceeds the ultimate loads, the PDM might break in parts and these remain in the bore hole. Bit overpull (ultimate load) Maximum loads on the components that were installed in the interior of the PDM if the bit is stuck in the hole. Once the drilling PDM has been subjected to loading beyond maximum static loads up to ultimate loads, it must be sent back for maintenance to the MICON Downhole-Tools GmbHto check whether PDM components have been damaged. Body overpull (ultimate load) Maximal stress on the outer components of the PDM when it is stuck in the hole. Once the PDM has achieved these values, it must be sent back for maintenance to the manufacturer to check whether PDM components have been damaged. Set down weight (ultimate load) This value is based on the maximum load on the PDM when it is stuck in the well, or has been placed on the bottom of the hole. Once the drilling PDM has achieved these values, it must be sent back for maintenance to the manufacturer to check whether PDM components have been damaged.

13 Guideline for performance chart The following performance chart of a PDM illustrates how to determine downhole operational torque and speed of the PDM, by a known flow rate and differential pressure. The speed of the PDM is indicated on the left y-axis and the torque from the right y-axis. The x-axis shows the differential pressure. In the diagram below, an example is given to illustrate how to determine downhole operational torque and speed of the PDM. In this example, the PDM is being run using 185 gpm with a differential pressure of 230 psi. To determine the downhole PDM speed, draw a line up from the differential pressure (230 psi) on the x-axis to the blue curve of 185 gpm (from point A to point B). Afterwards, draw a horizontal line from point B to the left y-axis (point C) and read the corresponded speed value. C B RPM RPM at 185 GPM (700 LPM) D E A Differential Pressure (psi) To determine the operational output torque, draw a line up from point A (differential pressure of 230 psi) to the diagonal dashed line (point D), and then a horizontal line to the right y-axis (point E) and read the torque value (about 650 ft-ibs). Note that the vertical red lines represent the operational limit for each elastomer of that specific PDM. Differential pressure values beyond these limits are not recommended. For those flow rates between the given curves, interpolate an appropriate curve between the printed curves. Dogleg severity capabilities This table details a typical dogleg severity capability chart for that particular PDM for common hole sizes. The table applies only for PDM with slick (unstabilized) bearing housing.
