BASIC OPERATION WHEN THE TOWNSEND "TYPE 84" ANNULAR PREVENTER IS IN THE OPEN POSITION, THE PACKING UNIT WILL HAVE FULL BORE CLEARANCE TO ALLOW FOR LARGE TOOLS TO PASS THROUGH. EACH TIME THE PREVENTER IS CLOSED AND RELEASED, THE PACKING UNIT WILL RETURN TO THE FULL OPEN BORE POSITION. WHEN THE HYDRAULIC PRESSURE IS APPLIED TO THE PISTON CHAMBER, IT PUSHES THE PISTON UPWARD CAUSING THE PACKING UNIT TO COMPRESS BECAUSE OF THE TAPERED INTERIOR OF THE PISTON. THE COMPRESSED RUBBER HAS NO WHERE TO GO BUT UPWARD THROUGH THE TOP OPEN BORE OF THE UNIT AND TOWARDS THE DRILL PIPE. ONCE THE WELL BORE PRESSURE COMES INTO CONTACT WITH THE COMPRESSED PACKING UNIT, IT WILL INCREASE THE CLOSING FORCE, REINFORCING THE SEAL OF THE UNIT COMPRESSING AGAINST THE DRILL PIPE. MOST CLOSING UNITS IN THE FIELD HAVE A SEPARATE "MANUAL REGULATOR VALVE" (MR VALVE) TO REGULATE ACCUMULATOR VOLUME TO OPERATE THE TOWNSEND "TYPE 84" ANNULAR PREVENTER. THE CLOSING TIME OF THE "TYPE 84" ANNULAR CAN BE REGULATED BY THE RATE OF FLOW OF THE HYDRAULIC FLUID FROM THE ACCUMULATOR TO THE PREVENTER. THE SHORTER THE DISTANCE AND LARGER THE LINES FROM THE ACCUMULATOR ALONG WITH THE VOLUME OF FLUID AVAILABLE FROM THE UNIT HAS A BEARING ON THE TIME IT TAKES THE UNIT TO CLOSE. DRILL PIPE

PACKING UNIT SELECTION TOWNSEND'S "TYPE 84" PACKING UNITS AND SEALS ARE MANUFACTURED UNDER TOWNSEND'S STRICT QUALITY PROGRAM. TOWNSEND'S PACKING UNIT AND SEAL COMPOUND IS SPECIALLY FORMULATED TO PERFORM UNDER FIELD OPER ATIONS. TOWNSEND IS ONE OF ONLY TWO MANUFACTURERS THAT MAKES EACH SET OF SEALS OVERSIZE AND THEN GROUND BACK TO PROPER SIZE TO CONFIRM THAT UNIFORMITY IS IN EACH SEAL THAT IS PLACED INTO OPERATION. THE PACKING UNIT COMPOUND THAT IS USED BY TOWNSEND HAS BEEN FORMULATED OVER THE PAST 30 YEARS TO CONFORM TO THE DIFFERENT APPLICATIONS OF THE "TYPE 84" ANNULAR BOP. THESE SPECIALLY FORMULATED COMPOUNDS CREATE THE BACKBONE BEHIND THE SUCCESS OF THE TOWNSEND PACKING UNIT AND ADDS TO THE STRENGTH AND DURABILITY OF THE "TYPE 84" ANNULAR ITSELF. EACH PACKING UNIT HAS FLANGED STEEL SEGMENTS TO ANCHOR THE PACKING UNIT AND CONTROL THE FLOW OF RUBBER AS THE HYDRAULIC PRESSURE IS ADDED TO THE PISTON AND FORCES THE RUBBER TO MOVE UPWARD THROUGH THE BORE CAVITY AND INWARD TOWARDS THE DRILL PIPE TO SEAL. ALL PACKING UNITS ARE SUBJECT TO WEAR EACH TIME THEY ARE CLOSED, WEAKENING THE RUBBER EACH TIME IT IS PRESSURED UP ON. TOWNSEND'S DESIGN AND UNIQUE COMPOUND SELECTION DETERS THIS WEAR AS LONG AS POSSIBLE. MOST CLOSURE WEAR IS ON THE INSIDE OF THE PACKING UNIT AND STRIPPING WEAR OCCURS IN THE INSIDE BORE OF THE UNIT. ALL TOWNSEND PACKING UNITS ARE TESTED AT THE FACTORY BEFORE THEY ARE PACKAGED FOR SALE AND ARE TESTED AGAIN WHEN INSTALLED INTO A NEW "TYPE 84" ANNULAR BOP TO CONFIRM TOWNSEND'S COMMITMENT TO QUALITY. EACH UNIT IS SERIAL NUMBERED FOR TRACTABILITY TO CONFIRM BATCH OF RUBBER EACH UNIT WAS MADE FROM AND DATE OF MANUFACTURE. TOWNSEND'S PACKING UNITS ARE AVAILABLE IN NATURAL RUBBER, NITRILE RUBBER AND NEOPRENE RUBBER.

NATURAL RUBBER IS COMPOUNDED FOR DRILLING WITH WATER-BASE DRILLING FLUIDS. THE UNIT CAN BE OPERATED IN TEMPERATURES -30° TO 255° F (35° C TO 107° C). THE NATURAL RUBBER PACKING UNIT IS IDENTIFIED WITH "NR" IN THE SERIAL NUMBER ON TOP OF ONE OF THE METAL INSERTS.

PACKING UNIT SELECTION (CONTINUED) NITRILE RUBBER IS COMPOUNDED FOR DRILLING WITH OIL-BASE DRILLING FLUIDS. THE UNIT CAN BE OPERATED IN TEMPERATURES BETWEEN 20° F TO 190° F (7° C TO 88° C). THE NITRILE PACKING UNIT IS IDENTIFIED WITH "NBR" IN THE SERIAL NUMBER ON TOP OF ONE OF THE METAL INSERTS.

NEOPRENE RUBBER IS FOR LOW-TEMPERATURE OPERATION SERVICE IN OILBASE DRILLING FLUIDS. THE COMPOUND IS FORMULATED TO OPERATE IN TEMPERATURES BETWEEN -30° F TO + 170° F (-35° C TO 77° C). NEOPRENE RUBBER IS ALSO DETRIMENTALLY AFFECTED BY EXTENDED HIGH PRESSURE APPLICATIONS. THE NEOPRENE UNIT IS IDENTIFIED WITH "CR" IN THE SERIAL NUMBER ON TOP OF ONE OF THE METAL INSERTS. HEAD GASKET

INSTALLATION OF PACKING UNIT TO REPLACE THE PACKING UNIT IN A "TYPE 84" ANNULAR FOLLOW THE FOLLOWING PROCEDURE: 1. REMOVE THE HEAD LOCKING SCREW. (MARKING THE LOCATION TO THE HEAD LOCKING SCREW HOLE ON THE SIDE OF THE OUTER BODY WILL HELP REALIGN WHEN REPLACING THE CAP.) 2. UNSCREW THE TOP CAP BY TURNING IT COUNTER CLOCKWISE. A CHEATER BAR WILL BE REQUIRED TO PLACE BETWEEN TWO EYE BOLTS PLACED IN STUD HOLES 180° APART FROM EACH OTHER. THE CHEATER BAR WILL TORQUE UP AGAINST THE SIDE OF THE EYE BOLTS. THE TOP CAP MAY BE DIFFICULT TO REMOVE BECAUSE IT WAS NOT GREASED PROPERLY BEFORE IT'S LAST ASSEMBLY OR MAY BE FROZEN IN PLACE BECAUSE OF TRASH OR RUST. A CATLINE OR WENCH MAY BE REQUIRED TO ADD ADDITIONAL TORQUE TO BREAK THE CAP LOOSE. (SAFETY SHOULD ALWAYS BE A CONCERN WHEN ADDING THIS ADDITIONAL TORQUE TO BREAK THE CAP LOOSE.) DO NOT HEAT THE HEAD WITH A TORCH.

3. ONCE TOP CAP IS LOOSE FROM THE THREADS IN THE PREVENTER BODY, REMOVE IT FROM THE BOTTOM BOWL USING THE TWO INSERTED EYE BOLTS. BE SURE THAT EYE BOLTS ARE SECURELY SCREWED INTO TOP CAP BEFORE LIFTING. 4. REMOVE THE DAMAGED OR WORN PACKING UNIT FROM THE BOTTOM BOWL USING TWO LIFTING EYES THAT MATCH UP WITH THREADS ON TOP OF THE UNIT. 5. INSPECT THE PISTON BOWL AND LUBRICATE WITH GREASE BEFORE PLACING NEW UNIT BACK INTO THE BOWL AREA. 6. CLEAN THE TOP OF THE CAP, INCLUDING THE THREADS AROUND THE CAP AND THE INTERNAL THREADS ON THE TOP OF THE BODY . ALSO GREASE THE THREADS IN THE BODY AND ON THE CAP WITH A ZINC BASE API TOOL JOINT LUBRICANT. 7. THE PACKING UNIT SHOULD BE SITTING EVENLY IN THE PISTON BOWL AND NOT COCKED TO ONE SIDE OR THE OTHER BEFORE REPLACING THE TOP CAP. BEFORE REPLACING THE TOP CAP, INSPECT THE HEAD LOCKING SCREW HOLE TO CONFIRM THAT THREADS ARE IN GOOD CONDITION AND HAVE BEEN GREASED AND FREE FROM TRASH. 8. REPLACE THE TOP CAP AND TIGHTEN CLOCKWISE UNTIL THE LOCKING SCREW BOLT HOLE ON THE CAP LINES UP WITH THE BOLT HOLE ON TOP OF THE BODY, AND INSTALL THE HEAD LOCKING SCREW AND CONFIRM IT IS TIGHT.

PREVENTER PRE-INSTALLATION INSPECTION 1. PRIOR TO INSTALLATION, CLEAN AND TEST THE ANNULAR PREVENTER BEFORE BEING PLACED INTO OPERATION OR MOVED TO ANOTHER JOB. PROLONG INTERVALS OF NON-OPERATION WILL CAUSE SEALS TO FREEZE UP AND POSSIBLY LOCK UP THE PREVENTER. (ALWAYS STORE THE ANNULAR PREVENTER IN AN UPRIGHT POSITION TO PREVENT UNDO STRESS ON INTERNAL SEALS FROM THE WEIGHT OF THE PISTON. 2. VISUALLY INSPECT THE BORE OF THE ANNULAR PREVENTER TO CONFIRM THAT THERE IS NO DAMAGE TO THE PACKING UNIT AND THAT THE RUBBER DOES NOT HAVE LARGE CHUNKS OF RUBBER MISSING FROM THE BORE OR IS CRACKED FROM THE WEATHER. 3. INSPECT FOR DAMAGE TO THE TOP AND BOTTOM RING GROOVE ON THE PREVENTER. CLEAN RING GROOVES PRIOR TO PLACING RING GASKET IN GROOVE WITH EMERY CLOTH AND LIGHTLY OIL. ALWAYS REPLACE RING GASKETS WHEN PREVENTER IS REMOVED OR PLACED ON WELLHEAD OR A JOINTING FLANGE. 4. INSPECT THE TOP BOLT HOLES IN THE TOP NUT TO CONFIRM THAT ALL STUD HOLES ARE FREE FROM TRASH AND ALL THREADS ARE IN GOOD CONDITION. REPLACE ANY STUDS AND NUTS THAT ARE MISSING. ALSO INSPECT THE BOTTOM STUD BOLTS IF THE ANNULAR HAS A STUDDED BOTTOM. 5. INSPECT THE THE STUDS AND NUTS ON TOP AND BOTTOM OF THE PREVENTER TO CONFIRM THREADS ARE NOT DAMAGED. CONFIRM THAT ALL STUDS ARE TIGHT WHEN BOP IS PLACED OVER THE HOLE AND ATTACHED TO CONNECTING FLANGE.. 6. INSPECT THE OPEN AND CLOSE PORT HOLES TO CONFIRM THAT THEY ARE CLEAN AND HAVE BEEN PLUGGED WHILE BEING STORED TO PREVENT TRASH FROM COMPROMISING THE INTEGRITY OF THE PREVENTER. DO NOT STICK RAGS IN THE OPEN AND CLOSE PORTS WHEN PLACING IN STORAGE. CONFIRM THAT THREADS ON CONNECTIONS ARE IN GOOD CONDITION.

INSTALLATION OF THE PREVENTER 1. BEFORE PLACING THE "TYPE 84 ANNULAR PREVENTER OVER THE HOLE, INSPECT THE INTERIOR BORE OF THE PACKING UNIT TO CONFIRM THAT IT IS IN FULL OPEN HOLE POSITION AND IS NOT COMPRESSED OUT INTO THE WELL BORE. 2. TOWNSEND HAS PROVIDED LIFTING EARS ON THE SIDE OF THE PREVENTER TO HELP LIFT THE PREVENTER OVER THE WELL BORE. JUST BEFORE PLACING THE ANNULAR PREVENTER OVER THE WELL BORE, PLACE A NEW RING GASKET IN THE FLANGE BETWEEN PREVENTER BODY AND THE FLANGE IT IS TO BE ATTACHED TO. INSPECT RING GASKET GROOVES IN BOTH FLANGES TO CONFIRM THEY ARE NOT DAMAGED AND FREE FROM TRASH AND RUST. CLEAN THE RING GROOVES WITH EMERY CLOTH IF NECESSARY. 3. TIGHTEN ALL BOLTS AND NUTS ACCORDINGLY. ONCE ALL NUTS ARE PLACED ON BOLTS AND HAND TIGHTENED, BEGIN TIGHTENING NUTS WITH A WRENCH OR IMPACT. TIGHTEN ONE NUT FIRMLY AND THEN CROSS OVER 180 DEGREES TO THE OTHER SIDE OF THE FLANGE TO TIGHTEN THE OPPOSITE NUT. ONCE THIS NUT IS TIGHTENED, CROSS OVER 90 DEGREES AND BEGIN TIGHTENING THE NEXT NUT, THEN CROSS OVER 180 DEGREES FROM THAT NUT TO THE OPPOSITE SIDE TO TIGHTEN THAT NUT. (GOOD EXAMPLE IS NORTH, SOUTH AND EAST WEST.) ONCE THE FOUR CORNER NUTS HAVE BEEN TIGHTENED, TIGHTEN ALL REMAINING NUTS GOING CLOCKWISE. RE-CHECK EACH NUT AS YOU GO CLOCKWISE AROUND THE FLANGE. EACH NUT SHOULD HAVE THE FOLLOWING TORQUE POUNDS OF FOOT PRESSURE. 7-1/16 X 3M FLANGE CONNECTION 7-1/16 X 5M FLANGE CONNECTION 9" X 3M FLANGE CONNECTION 9" X 5M FLANGE CONNECTION 11" X 3M FLANGE CONNECTION 11" X 5M FLANGE CONNECTION 13-3/8" X 3M FLANGE CONNECTION 13-5/8" X 5M FLANGE CONNECTION -

OPERATION OF PREVENTER 1. MOVE THE SELECTOR SWITCH ON THE CLOSING UNIT TO THE CLOSE POSITION. THE HYDRAULIC PRESSURE WILL PUSH THE INTERNAL PISTON UPWARD COMPRESSING THE PACKING UNIT AROUND THE DRILL PIPE. 2. TO RETURN THE PACKING UNIT TO OPEN HOLE POSITION, MOVE THE SELECTOR SWITCH ON THE CLOSING UNIT TO THE OPEN POSITION. 3. MOST ACCUMULATORS ARE EQUIPPED WITH MANUAL REGULATOR VALVE (MR VALVE) WHICH IS USED TO REDUCE THE ACCUMULATOR FLUID PRESSURE TO A MAXIMUM OF 1500 PSI FOR THE OPERATION OF THE ANNULAR PREVENTER. PRESSURE SETTINGS ON THE ANNULAR ARE VERY IMPORTANT TO PROLONG THE LIFE OF THE ELEMENT IN THE PREVENTER. IT IS NECESSARY TO FOLLOW THE MANUFACTURERS RECOMMENDATION AS TO THE MAXIMUM OPERATING PRESSURE WHEN CONTROLLING THE WELL AND DURING STRIPPING OPERATIONS. IF THE ANNULAR REGULATOR VALVE IS MANUALLY OPERATED ALWAYS CHECK THE ANNULAR PRESSURE GAUGE ON THE ANNULAR REGULATOR.

CAUTION IF THE PACKING UNIT DOES NOT FULLY RETRACT FROM THE WELL BORE, THE UNIT CAN BE DAMAGED WHILE DRILLING OR PREVENT LARGE TOOLS FROM BEING INSERTED INTO BORE CAVITY.

MAINTENANCE THE TOWNSEND "TYPE 84" ANNULAR BLOWOUT PREVENTER REQUIRES A MINIMUM AMOUNT OF MAINTENANCE. HOWEVER; IT IS IMPORTANT TO PERFORM MAINTENANCE ON ALL BLOWOUT PREVENTERS TO PREVENT UNFORESEEN DEVIATIONS IN A WELL CONTROL SITUATION.

TYPE 84 ANNULAR BOP PRE-SERVICE DISASSEMBLY & ASSEMBLY TOWNSEND SUGGEST THAT THE OPERATOR SHOULD CLEAN AND LUBRICATE ALL PARTS AND SEALS WHEN ASSEMBLING OR REPLACING SEALS OR A PACKING UNIT. IT IS MORE ECONOMICAL TO CHANGE ALL SEALS WHEN REPAIRING THE PREVENTER. (IF A PARTICULAR SEAL IS WEAK, THE OTHERS MOST LIKELY NEED TO BE REPLACED ALSO.) NEVER PERFORM WELDING ON THE ANNULAR PREVENTER IN THE FIELD SINCE THE TYPE 84 ANNULAR IS A PRESSURE VESSEL. IT WILL PUT UNDO STRESS ON THE PREVENTER BODY. ANY WELDING PERFORMED ON THE PREVENTER SHOULD BE IN A SHOP ENVIRONMENT AND SHOULD BE PROPERLY S TRESS RELIEVED.

ONCE THE "TYPE 84"" ANNULAR PREVENTER HAS BEEN REPAIRED AND REASSEMBLED, IT SHOULD BE SHOP TESTED TO CONFIRM ALL COMPONENT PARTS ARE OPERATING PROPERLY.

DISASSEMBLY & ASSEMBLY (REFER TO EXPLODED OF THE "TYPE 84" BLOWOUT PREVENTER)

1. REMOVE THE HEAD LOCKING SCREW FROM THE PREVENTER. MARKING THE LOCATION OF THE HEAD LOCKING SCREW HOLE ON THE OUTSIDE OF THE OUTER BODY WILL HELP REALIGN SCREW HOLES WHEN REASSEMBLING. (ITEM 3) THE TOP CAP MAY BE DIFFICULT TO REMOVE BECAUSE OF IMPROPER GREASING BEFORE ITS LAST ASSEMBLY OR MAY BE FROZEN IN PLACE BECAUSE OF TRASH OR RUST. A CATLINE OR WENCH MAY BE REQUIRED TO ADD ADDITIONAL TORQUE TO BREAK THE CAP LOOSE. (SAFETY SHOULD ALWAYS BE A CONCERN WHEN ADDING THIS ADDITIONAL TORQUE TO BREAK THE CAP.)

ONCE THE TOP CAP IS LOOSE FROM THE THREADS IN THE PREVENTER BODY, REMOVE IT FROM THE BOTTOM BOWL USING THE TWO INSERTED EYE BOLTS. BE SURE THAT EYE BOLTS ARE SECURELY SCREWED INTO TOP CAP BEFORE LIFTING. (ITEM 4 - 12) 4. VISUALLY INSPECT THE INTERIOR OF THE TOP CAP FOR DAMAGE TO THE INSIDE WEAR PLATE. IF IT IS DAMAGED REPLACE IT. (ITEM 4 - 5) WEAR PLATE IS SUBJECTED TO STRESS AND AGING PRODUCED BY THE MOVEMENT OF THE PACKING UNITS AGAINST THE PLATE WHEN HYDRAULIC PRESSURE IS APPLIED. 5. REMOVE THE PACKING UNIT FROM BOTTOM BOWL USING TWO LIFTING EYE BOLTS THAT MATCH UP WITH THREADS ON TOP OF THE PACKING UNIT. (ITEM 8) 6. LIFT THE PISTON FROM THE BODY BY PLACING EYE BOLTS IN THE PREDESIGNATED SCREW HOLES ON TOP OF THE PISTON. (ITEM 11 - 12) 7. INSPECT THE INTERNAL BODY FOR WEAR AND DAMAGE. PAY CLOSE ATTENTION TO SEAL AREAS AND WHERE SEALS SEAL AGAINST INTERIOR WALLS AND THREAD AREAS OF THE UPPER NUT AND THE BOP BODY. IF SEALS AREAS ARE WORN, SCARED, SCRATCHED, SCORED, PITTED OR DAMAGED IN ANYWAY, THE UNIT SHOULD BE SENT TO A MACHINE SHOP FOR REPAIR. SOME MINOR SCRATCHES AND PITS CAN BE REMOVED BY USING EMERY CLOTH. REMEMBER TO SEND PREVENTER BACK TO TOWNSEND INTERNATIONAL OR AN AUTHORIZED TOWNSEND REPAIR CENTER FOR MACHINING. ALL PARTS THAT ARE WELDED ON SHOULD BE STRESS RELIEVED.

MAINTENANCE DISASSEMBLY & ASSEMBLY CONTINUED 8. INSPECT THE UNIT FOR WEAR, CRACKS AND CHUNKS OF RUBBER MISSING FROM THE INTERIOR. TIME, WEATHER AND EXPOSURE TO OZONE GASES WILL CAUSE UNIT TO CRACK OVER TIME OR BECOME HARD. HARDNESS OF THE UNIT CAN BE CHECKED BY TAKING A BALL POINT PEN AND PRESSING ON THE RUBBER IN DIFFERENT AREAS TO SEE IF THE RUBBER GIVES UNDER PRESSURE AND RETURNS TO PLACE. IF THE RUBBER IS HARD IT WILL FELL LIKE PRESSING ON A ROCK AND WILL HAVE NO GIVE. IF THE RUBBER IS HARD, CRACKED OR DAMAGED, REPLACE THE UNIT. (ITEM 8) REMEMBER TO GREASE INTERIOR OF PISTON BODY BEFORE PLACING PACKING UNIT BACK INTO BOWL AREA AND CONFIRM THAT PACKING UNIT IS NOT COCKED AND IS SITTING LEVEL.

9. REMOVE AND INSPECT ALL SEALS FOR NICKS, CUTS AND DAMAGE TO THE LIP SEALING AREA. WORN OR DAMAGED SEALS SHOULD BE REPLACED. SEALS ALSO CAN BECOME HARD OVER TIME, THE PEN TEST CAN ALSO BE APPLIED TO THE SEALS TO CONFIRM THEIR ELASTICITY. IF SEALS ARE HARD OR DAMAGED, REPLACE THEM. ALSO INSPECT SEAL AREA AND REMOVE ANY TRASH OR RUST THAT MAY HAVE ACCUMULATED BEHIND SEAL DURING SERVICE. SEAL AREAS CAN BE CLEANED WITH EMERY CLOTH. WHEN REPLACING SEALS BE SURE IN THE AREAS THAT REQUIRE TWO SEALS, ALWAYS PLACE THE UPPER SEAL WITH LIP FACING UPWARD AND THE BOTTOM SEAL WITH LIP FACING DOWNWARD. THE TOP SEAL IS FOR PUSHING THE PISTON DOWN WHEN OPENING THE UNIT BACK UP TO OPEN HOLE CONFIGURATION AND THE BOTTOM SEAL IS USED FOR LIFTING THE PISTON UP FOR CLOSURE. IN MOST CASES THERE IS MORE STRESS ON THE BOTTOM SEAL THAN THE UPPER SEAL BECAUSE THE WEIGHT OF THE PISTON ASSIST IN ALLOWING THE PISTON TO PRESS DOWNWARD. IN A FIELD SITUATION, IF THE LOWER PISTON SEAL IS LEAKING, THE UPPER SEAL CAN BE REMOVED AND PLACED IN THE LOWER SEAL AREA AND UNIT WILL PERFORM PROPERLY UNTIL THE PREVENTER CAN BE SENT TO A SHOP FOR REPAIR. 10.

FOR ADDITIONAL INFORMATION ON API 16A, APPENDIX F SPECIFICATIONS, CONTACT API FOR THEIR CURRENT PUBLICATION OR CONTACT API THROUGH THEIR WEB PAGE. THE FIELD WELL BORE PRESSURE TEST CAN BE PERFORMED WHILE THE BOP IS IN A STACK, WELLHEAD, OR ON A TEST STUMP OR BLIND FLANGE. MAXIMUM PACKING UNIT LIFE IS MAINTAINED WHEN MINIMUM STRESS IS PLACED ON THE UNIT WHEN APPLYING HYDRAULIC PRESSURE TO THE CLOSING CHAMBER OF THE BLOWOUT PREVENTER TO ACCOMPLISH AND MAINTAIN A SEAL OFF ON THE RECOMMENDED TEST PLUG. 1. TEST PRESSURE SHOULD BE THE LOWEST RATED WORKING PRESSURE OF ANY COMPONENT OR CONNECTION WHICH WILL BE PRESSURIZED DURING THE TEST. 2. THE WELL BORE PRESSURE TEST FLUID SHOULD BE COLD WATER OR DRILLING FLUIDS. 3. APPLY HYDRAULIC PRESSURE TO THE CLOSING CHAMBER UNTIL THE PACKING UNIT SEALS OFF AGAINST THE TEST PLUG OR PIPE. 4. ONCE THE PACKING UNIT IS SEALED OFF AGAINST PIPE, WELL BORE PRESSURE CAN BE APPLIED. AS WELL BORE PRESSURE IS INCREASED, THE CLOSING FORCE WILL INCREASE ON THE PACKING UNIT CREATING A TIGHTER SEAL. ONCE THE WELL BORE PRESSURE IS INCREASED TO THE MAXIMUM PRESSURE ALLOWED, CLOSING PRESSURE SHOULD BE PROPORTIONALLY REDUCED AS THE WELL BORE PRESSURE INCREASES. (REFER TO CONTROL PRESSURE CHART FIGURE 1-1 LOCATED IN MANUAL AFTER THIS PROCEDURE.) CLOSING PRESSURE REQUIRED TO SEAL OFF UNIT VARIES BETWEEN PACKING UNITS. THE VARIATION IS CREATED BY AGE OF UNIT, COMPOUND OF UNIT AND SOMETIMES WEATHER CONDITIONS. COLD WEATHER AFFECTS MOVEMENT. TEST WITH RECOMMENDED INITIAL CLOSING PRESSURE.
