9 Introduction This section describes basic operating procedures, which are used in the field and will facilitate proper operation of Cobra motors. Motor Operations: Cobra Drilling Motors offers are wide range of drilling motor configurations which are designed to accommodate various types of drilling applications. When selecting the right size motor and configurations for the application, it is important that you consider hole size, drilling fluid, hole temperature, well profile and bit selection. Cobra motors can be configured to match the torque requirements of the bit, flow rates for optimum hole cleaning or high temperature application. We recommend contacting your Cobra sales representative to discuss the scope of your project to ensure proper motor selection. Preparation for Running and Motor Make Up Cobra motors are shipped from the service facility with all components inspected and all tool connections made up to the proper torque requirements. Motors are shipped with a sleeve protector covering the screw-on stabilizer. When a screw-on stabilizer is ordered it will be installed and torqued at the Cobra service center. Procedures 8

10 Motor Surface Flow Test 9 1. Set the motor in the slips and install safety clamp. 2. Remove lift sub and make up Kelly. 3. Lower the motor below the rotary table. 4. Start the rig pumps slowly and pump only enough to open the float valve and run the motor. Use minimum flow rate then gradually increase it. 5. Make note of the circulation rate and standpipe pressure. 6. Raise the motor to verify rotation of the bit box to ensure tool is operating properly. 7. Lower the motor until it is below the rotary table and set slips. Procedures

11 BREAK Pick the motor up, and attach the selected bit. If a bent housing adjustment is needed, lower the motor down to the adjustable housing, and make the needed change according to the accompanying setting procedure (see below and on pg. 81).

Upon completion of the setting procedure, mark the tool face, and slowly lower the motor into the hole, keeping tool face alignment as you go. At this point, you can align and test whatever steering device is to be used, and proceed on in the hole. Procedures 10

12 Running In The Hole 11 When using a Cobra motor set the angle on the Adjustable Sub of motor as shown on the Cobra adjustable setting procedure (page 81). Carefully pass the motor through Blowout Preventers, casing points, liner hangers, or key seats to prevent being hung up. Also control the tripping speed to avoid damage from striking bridges, shelves etc. Ream through the tight spots if any by starting the pumps & reaming slowly. Excessive reaming reduces motor life; however Cobra has provided special thrust bearings for this application. DO NOT run motor into the bottom of the hole, this can cause bit and motor damage. Reduce speed while approaching the last two to three singles of the hole. Gradually lower the motor until tagging bottom and apply Weight on Bit (WOB). As the bit begins to contact formation, torque is required to maintain WOB and produce penetration, by increasing pump pressure. The difference between the on bottom pump pressure and off bottom pump pressure is the differential pressure. This differential pressure is directly related to the torque output of the motor. By varying WOB and flow rate, optimal penetrating rate can be found. Please see the appropriate Motor Performance Graph for designed parameters. Procedures

13 Rotating The Motor Rotating the drill string up to RPM may be applied to promote optimal drilling rates but should never be rotated if motor is set at more than1.5 degree with two stabilizers, 1.83 degree with single stabilizer & 2.12 degrees slick or higher as this may cause the serious damage to the motor and also increases the risk of motor joint breaking down hole. Stall Indication/Reaction A motor stall is indicated be a sudden increase in standpipe pressure while drilling. When a stall occurs, it is important to cut back pump strokes before lifting the motor off bottom. This reduces the pressure in the power section and will allow the driller to restart the motor. Stalls are very damaging to stator rubber as well as other internal components and should be avoided. Parameters to observe while Drilling/Trouble-shooting Sudden Increase in Circulating Pressure May be the cause of bit/motor plugged with cuttings, excessive side loading, or motor locking up. May occur due to motor stall. Pick up off bottom and return to bottom with less weight Procedures 12

14 Decrease in Circulating Pressure 13 May be the cause of the drill string being washed out, or drilling fluid being lost in formation. Lost circulation can cause a decrease in pressure, if there are no returns, check pit levels. Differential Pressure Sudden Increases in Differential Pressure may be a result from a motor stalling or a bit balling up, or formation changes. Sudden decrease in Differential Pressure may be attributed to bit damage, formation, or hanging up in hole. Decrease In ROP Drop off in ROP may be the cause of a worn stator, Increase in wall drag, poor bit selection for formation type, worn bit, or a motor stall. Drill bit is balled up. Note: If the motor stalls because of weight on bit, DO NOT lift off bottom until you have backed off on the pumps. Failure to do this can cause severe damage to the motors power and drive sections. Procedures

15 Pulling Out of Hole and Motor Lay Down Care should be taken when pulling a bent housing motor through the BOP stack. A bent motor may damage the internal components of the stack. A check of the bearing stack play measurement should be made to determine if the motor should be re-run. It is good practice to circulate off-bottom and remove cuttings prior to pulling out of hole. After pulling out of hole, follow the rig site maintenance steps shown below: 1. Place the bit in a bit breaker and remove any remaining fluid from the motor. 2. Use rig tongs to secure the motor above the rotating bit sub. 3. Turn the rotary table and bit counterclockwise to pump any remaining drilling fluid out of the top of the motor. 4. It is good practice flush the motor with fresh water by holding the bearing housing above the bit box and rotate the bit box clockwise while at the same time running water through to the top of the motor. 5. If your tool has an optional dump valve, pour clean fluid into the top of it. Work the piston until it moves freely. 6. If you will be storing the tool for an extended period of time, add a small amount of mineral oil to the motor. Do not use diesel oil. Procedures 14

16 Determining Thrust-Bearing Life 15 For Cobra mud lube bearing assemblies, check thrust bearing wear to estimate remaining bearing life before re-running the motor. The amount of wear in the bearing can be determined by how much drive shaft play exists in the thrust stack by measuring between the gap between the end nut and bit box. 1. Lift the motor from the rig floor so that it hangs freely. 2. Measure the distance between the bearing housing end nut and the drive shaft bit box (X). 3. Lower the motor back to the floor. 4. Re-measure the distance between the bearing housing end nut and the drive shaft bit box (Y). 5. Determine the amount of wear by subtracting (X Y). If the gap exceeds the numbers in the reference table to the right. The motor should be by layed down and returned to the Cobra service center for service. Bearing Play Table Motor Size X-Y X-Y (O.D.

17 Drilling Fluids: Cobra motors can be used with various types of drilling mud, but there are factors to consider. Some drilling fluids and additives may be harmful to the elastomer of the power section stator, as well as the power section rotor and other motor components. Below are factors to consider: The ph of the drilling fluid should be considered. A drilling fluid that is too acidic (ph < 4) or too basic (ph > 10) will damage the power section. When using fluids close to these limits, circulation must be maintained to reduce damage to the elastomers and the rotor coating. After using acid-based fluids, it is important to properly flush the motor and service it as soon as possible Mud Solids should be controlled at all times. Sand content should be (2% or less) Drilling fluids exceeding (2%) will cause erosion which becomes a serious problem with the elastomers and the washing of internal motor components. Oil based fluids can be used, but can reduce the life of the stator by damaging and swelling the elastomer in the stator. The degree of damage depends on the oils used. It is recommended to reline the stator after each run, as the swelling will lead to increased compression, which leads to heat build-up and chunking of the stator elastomer and potential motor failure. Procedures 16

18 Drilling fluids containing chlorides can reduce rotor and stator life due to corrosion, especially at elevated temperatures. Special attention should be paid to the internal coatings when the chloride concentration is in excess of 30,000 PPM. The motor should be flushed and serviced as soon as possible if it has been exposed to chlorides. 17 Downhole Temperature (Hot Hole Environments) The motor power section has an interference fit between the rotor and stator to establish a seal. For efficient motor operation, the interference fit must be maintained within a specified range. Cobra motors are designed to be used within specific temperature ranges, either below 250 degrees F (120 degrees C) or above 300 degrees F (150 degrees C). Elastomers used in standard power sections are designed to operate in temperatures up to 250 degrees F (120 degrees C). If the application operating temperature is expected to exceed these limits, an oversize power section should be considered to provide additional clearance to compensate for swelling of the stator elastomer. * Note Temperature is also a factor in performance. In the case of hot hole applications, Cobra will supply specialized power sections. DO NOT attempt to use these in areas of low temperature. These stators have a loose fit designed to incorporate swelling or specialty elastomers. If used in lower temperatures, it will only provide a small percentage of power specified. Procedures

19 High temperatures at the bottom of the hole can increase the interference fit, resulting in stator damage or reduced motor longevity. Select your drilling motor based on the temperature range is most likely to be operated in. If the bottom hole circulating temperature (BHCT) exceeds 250 degrees F (120 degrees C), use the following guidelines: Contact your Cobra sales representative for information on ordering a hot-hole motor. When tripping in the hole and the stage where the temperature is estimated to be 250 degrees F (120 degrees C) is reached, stop and circulate cool fluid to the motor for several minutes, at low volume, to reduce the temperature of the tool. Continue to pause and circulate cool fluid every 500 to 1,000 feet until the drilling depth is reached. Keep periods of non-circulation as brief and infrequent as possible. It is recommended that the operating differential pressure be reduced when working in high temperature hole conditions. Procedures 18

20 Power Section Graph Explanation MAX MAX DIFF. 19 Cobra Downhole Motors offers a wide range of motor OD sizes and configurations of power sections including: standard rubber, hard rubber, and even wall. The following sections show the specifications recommended for proper operation of Cobra motors. Each of the graphs illustrated in the Cobra Handbook show the characteristics of any power section on the market: DIFFERENTIAL PRESSURE, R.P.M., TORQUE and FLOW RATE. R.P.M. TORQUE LINE G.P.M. 400 G.P.M. 300 G.P.M. FLOW 10, TORQUE FT - LB As with all manufacturers, Cobra power sections have an OFF BOTTOM PRESSURE required to begin rotation. As the volume increase, this pressure increases due to efficiency of the power section. These pressures will vary with standard rubber, hard rubber and even wall, hot hole, oversize and double oversize. All manufactures ratings vary so for the Cobra graphs we will use a BASE LOSS of 100 p.s.i. at the lowest volume MAX. DIFF. PRESSURE DIFFERENTIAL PRESSURE P.S.I. Procedures

21 MAX MAX DIFF. FLOW FLOW To begin, determine your system pressure by pumping at the LOW FLOW RATE (as in this example 300 gpm) and record this pressure. This is your OFF BOTTOM PRESSURE (OBP). Now begin to pump the volume you require and record this pressure. The difference between this pressure and the original OBP recorded, plus the 100 p.s.i. (BASE LOSS), equals your new OBP. Subtract your new OBP from the published MAX DIFF. PRESSURE (as in the example 1125 p.s.i.). At that amount on the DIFFERENTIAL PRESSURE P.S.I. line, draw a vertical line to intersect the TORQUE LINE. From that intersection, draw a horizontal line to the right to intersect the TORQUE FT-LB line. This will be your torque (at that volume) when you set down and reach MAX. DIFF. PRESSURE. R.P.M. TORQUE LINE G.P.M. 400 G.P.M. 300 G.P.M MAX. DIFF. PRESSURE DIFFERENTIAL PRESSURE P.S.I. 10, TORQUE FT - LB Procedures 20

22 FLOW MAX MAX DIFF. 21 At the DIFFERENTIAL PRESSURE you are running when on bottom drilling, again draw a vertical line from the DIFFERENTIAL PRESSURE P.S.I. line to intersect the curved line representing the volume you are pumping. At this intersection, draw a horizontal line left to intersect the R.P.M. line. This will be the speed, R.P.M, at which the bit should be turning. It should be noted that consideration should be given to the type of bit being run, formation being drilled, and the medium being pumped. All of these can cause variations in the performance of the tool. NOTE!! If you stall the motor, NEVER lift off bottoms before cutting back your pumps. This can cause severe damage to the stator rubber or could cause a back lash backing off a connection. R.P.M. TORQUE LINE G.P.M. 400 G.P.M. 300 G.P.M FLOW MAX. DIFF.
