RE: Shut in19 Jul 2018 14:29
Seems like a pressure test:
a) The well is flowing, then the shut in is proceeded as follows:
- Set the string on the slips
- Install a fully opening safety valve in open position. Close the valve once is installed
- Open choke line valve at BOP stack (HCR valve)
- Close annular BOP
- Close choke.
- Read and record pressures and times, check pit volumes
It depends on the situation to weather to start killing procedures or to strip back to the bottom.
- If the stripping is faced, then, Stab IBOP (Grey valve)
- Open the fully opening safety valve
- Reduce the annular pressure and start stripping the string to the bottom
