BOP PRESSURE TESTING PROCEDURE - Contract …

1 Romfor International Ltd. STEP SUB PROCEDURE REMARKSBOP PRESSURE TESTING PROCEDURE1 Discuss Operator BOP requirementsWITH RIG that all Romfor's BOP equipment is tested consistentwith Romfor's policy. This may require Nabors to incur thecost for the TESTING subcontractor as well as provide rigtime to the Operator for the Requirements - Hard Hat, Safety Glasses, WorkGloves, Steel Toe Shoes, Back Support, and Anti-FallProtection. Fit for Duty check on all JSA for PRESSURE TESTING Manager to discuss procedures with pressuretesters. This is to include: -Stack design (Class II, IV, etc.) -The proper size and type of test plug to fit the casinghead. -Position, size and PRESSURE rating of choke manifold andvalves. -Wellhead rated working PRESSURE . -The drill pipe grade and operating PRESSURE of the drillpipe.

2 -Casing burst PRESSURE . -Ensure testers have the 1502 model unions. -The use of methanol -water for TESTING in freezingweather. -Outline the overall TESTING and the specific valves thatare to be tested. -BOP test will be noted on the IADC Daily Drilling Reportform. -Inform testers of low -high test the following items are ready or available, asrequired: -Adequate tie off points are in place to assure 100% tieoff. -Fluorescent vest. -Designate qualified man to be flagger. -Two way communication., -Proper API ring gasket is used if repairing a leak. -Proper size hammer wrenches and hammers, AWARE OF CONTRACTAND PERMIT Full Body Harnesses are tobe inspected prior to any all third party to Romfor's Drilling PolicyBOPE TESTING condition of the test Romfor's drill pipe designcriteria of 80% of Used area is clean and cleared BOP equipment PRESSURE tests are tobe recorded on a chart and maintained bythe TESTING subcontractor for 6 antifall protection Not reuse old API ring bolts, wrenches, hammers andAPI rings are cleaned and in STEP SUB PROCEDURE REMARKSR omfor International PRESSURE TESTING -Cellar covers are to be reinstalled as soon as practical.

3 -All wellhead, Blowout Preventers, valves, and fail -safesshall be PRESSURE tested from the direction they wouldbe exposed to well PRESSURE . -All BOP equipment should be tested every 14 days orwhen the integrity of the BOP stack has beencompromised ( changing rams, seals, or lifting thestack.) -Casing head wear bushing is not installed. -Have correct wear bushing retrieval tool on TO TEST BOP STACKThis PROCEDURE is based on a three ram BOP stackthat is nippled up. Refer to the rig specific the test, the Rig Manager and the Tester willensure that all personnel are fully aware of their requiredassistance, including any needed emergency the TESTING area is secure with caution blowout prevention equipment, except annular BOP s,will be PRESSURE tested to the minimum of the anticipated wellhead PRESSURE (if known).

4 80% of casing burst PRESSURE rating of the PRESSURE rating of the BOP BOP s should be tested to 70% of rated BOP equipment tests must include a low- PRESSURE testof 250 psi before proceeding to the full PRESSURE PRESSURE held (and recorded) for a minimum of fiveminutes after full PRESSURE has been establishedrepresents a satisfactory PRESSURE rotary bushings arelocked if left H2S is present allpersonnel must possess a to any work, a Job SafetyAnalysis (JSA) shall be conducted inthe presence of the rig crew, toolpusher, company representative andany service company which may beimpacted by the test.

5 STEP SUB PROCEDURE REMARKSBOP PRESSURE TESTING PROCEDURE3910111213141516 Ensure that the casing valve isopen and not high- PRESSURE connections associated with the wellcontrol equipment ( choke & kill line valves, chokemanifold valves, TIW valves, floor safety valves, insideBOP (Gray) valves) are to be isolated and PRESSURE testedduring each BOP the integrity of the BOP stack has beencompromised ( changing rams or lifting the stack), thecompromised component must be re-tested. Thisincludes TESTING the ram and associated bonnet seals, orbody TESTING a flange possibility of test PRESSURE leaking past a packoff ortest plug and being applied to a weaker element ( collapse, lower rated ring gasket, etc.) must alwaysbe considered. All reasonable steps should be taken tomonitor and eliminate this TESTING BOPEThe TESTING Technician will then check the wellhead toensure the right test plug for that particular wellhead isavailable (Size, Type, and working PRESSURE ) and ensureall lockdown bolts are TESTING Technician will then check the drill pipeconnection taking his tie-in-connection (called a top head& kelly sub) and screw it on a joint of pipe to check TESTING Technician will connect the PRESSURE recorder,fill his tank with water, and pre-test pump, hose, TESTING Technician will communicate with the RigManager and Company Representative to see if the chokemanifold can be tested while tripping pipe.

6 If not, thechoke manifold shall be tested during BOP THE CHOKE MANIFOLDThe choke manifold is then tested by:Closing the manual valve next to the BOP on the test line to choke all valves in the proper STEP SUB PROCEDURE REMARKSR omfor International PRESSURE TESTING filling stack, ensure thatthe choke manifold can bepumped to rig specific casing valve to ensure inopen position and not no fluid leaks out ofcasing TESTING , the rig floor will beclear of all 's policy is a minimum offive minutes of test on the sure header (watermelon, etc.) is a test is achieved, close the next set of valves, openvalves behind the set that was closed and continue thisprocess until all valves have been THE LOWER BOP STACKOnce drill crew is ready for TESTING Technician, thetechnician will then check inside of BOP stack to makesure wear bushing is out of hole, hole is clear of any debrisand is full of fluid up to Driller will pick-up test joint and put it into themousehole.

7 Screw pump-in-sub into the box connectionof the test joint. The driller will then torque up the pump-in-sub to the desired torque for that Driller will then pick up the test joint and the technicianwill screw on the test plug to the bottom or pin end of thetest joint (handy not tight). The TESTING Technician will thendope the seal area of the test plug. The driller will set thetest plug in the crew fills stack with water and the Driller checks theseat of the test TESTING Technician will then hook up his test hose fromthe test pump to the pump-in Driller will close the bottom pipe bottom pipe rams are closed - the TESTING Technicianwill then fill up the joint of pipe and PRESSURE up to 1,000and bleed off (to release air out of pipe). He will repeat thisprocedure a second time to release remaining air in thetest joint.

8 This needs to be done before BOP TESTING startsto remove air from entire system. This should only berequired on first air is released, the technician will then put the pen onthe PRESSURE recorder and PRESSURE up for the low test (forexample - 250 low). After the time span required by thecompany representative, the TESTING Technician will thengo to the high test (required by the company man) (forexample - 10,000 high). When the test is complete, theTesting Technician will then log in a tally book the first testinformation. Then bleed down the PRESSURE to International Ltd. STEP SUB PROCEDURE REMARKSBOP PRESSURE TESTING PROCEDURE5 Open bottom technician will have the crew remove the insides of thekill line check valve and re-install the cap on the valvesecurely. Note: This must be done to detect any leakson the kill THE UPPER BOP STACKOnce the check valve s internal parts are removed and thecap reinstalled, close the top rams, the HCR valve and theoutside kill line up to recommended test pressures.

9 After the testis complete, the technician will bleed down to zero and loginformation concerning inside or primary choke line valve and inside orprimary kill line valve. Open HCR valve and outside kill linevalve. PRESSURE up to recommended test pressures; holdfor desired time and bleed down to zero. Then loginformation concerning must install parts back into the check valve. With theinside choke line closed and top pipe rams still closed, theTesting Technician will then open the inside kill line valveand test to the recommended test PRESSURE . Once held forthe desired time, bleed to zero and log information. Note: Iftest for blind rams and choke are done from kill line, theninside parts of check cannot be installed at this THE ANNULAR PREVENTORThe TESTING Technician will have the Driller close the hydrilfirst, then open the TOP pipe rams.

10 (This will prevent thetest plug from becoming unseated in the wellhead.) Close akill line valve and a choke line valve and test to therecommended test PRESSURE . Once held for the desiredtime, bleed to zero and log technician will remove his test hose from the top of thetest joint and unscrew the test joint from the test plug andremove it from the table area will be clear ofall table area will be clear ofall personnel.
