• Use water to test BOP’s. The reason is that water has less compressibility than mud.
• Make up testing assembly and set in into a wellhead profile. Ensure that the casing valve must be left opened and there must be personnel monitoring the outlet of casing valve all time while testing. You must ensure that personnel who monitor the outlet must stay for from the BOP while it is being tested. The reason behind this step is to prevent pressure build up in the casing if the test plug is leaking.
• Circulate through choke/kill lines, choke manifold, standpipe manifold, and valves to ensure that all lines are full with water. This practice is for preventing pressure dropping off while testing.
• Line up cement unit and rig team shut rams and valves as per each rig specific testing sequence
• Pressure test must be low and high, respectively, and the pressure should be stabilized with minimum bleed off at least 5 minutes. Ensure that pressure recording on a chart is recorded correctly.
• Ensure that any equipment doest not pass a pressure test requirement must be reported to supervisors.
• Continue pressure testing until all equipment is tested as per each rig specific.
• Rig down testing assembly.
