WELL CONTROL READINESS
RECOMMENDED BEST PRACTICES (CONTINUED)
Prior to soak test,
complete: • EDS
• EHBS
• Function test
• Acoustic testing
• Pressure testing
• Setting of accumulator Pre-charge
Pre-deployment electrical integrity tests
After soak test
• •
• •
Remedial actions
Administrative • Include a section for handwritten notes for each test section of your RSOP. This will assist in creating
maintenance actions within your maintenance management systems.

Digital Troubleshooting
• Monitoring Pilot readback will give a good indication to where an issue is rooted. E.g.: working pressure – pilot
pressure = differential
• Pressure trend shape recognition can be informative to the root cause of pressure oscillations.

• Remote monitoring can expedite troubleshooting if communication between onshore and offshore teams is in
place prior to beginning tests.

Troubleshooting PODS Isolating
Systems • Certain OEMs have control POD “test” capabilities. When fault finding, there may be an advantage to placing
POD stingers inside of their test ring to determine where the leak or leak off is originating from. (CAUTION: Start
with lower pressures as to not wash stinger seals.)
Drift BOPs
Skid BOPs to Well Center
Check Stack and LMRP Bullseyes once Stack is picked up on first joint of riser.
