BAKER HUGHES - Drilling Fluids Reference Manual

PRESSURE PREDICTION AND CONTROL
3. If flow is noted, open the HCR-valve and close the BOP with the annular preventer.
4. Record shut-in drillpipe and casing pressures.
5. Record volume gain and mark pits.
6. Weigh fluid in suction pits.
7. Check blowout preventer and manifold for leaks.
8. Check flowline and choke exhaust lines for flow.
9. Check accumulator pressure.
10. Initiate well kill procedures.
Procedure for Closing Well In While Tripping
1. If a flow is detected, install and close a safety valve.
2. Position tool joints and close annular preventer.
3. Install an inside preventer and open safety valve.
4. Record casing pressure.
5. Check blowout preventer stack and manifold for leaks. Check valves for correct
position.
6. Check accumulator pressure.
7. Begin stripping to bottom.
It is always easier and requires less fluid density to kill a well with the bit at or near the bottom
of the hole. If a well kicks while drilling, the pipe should not be pulled into the casing. If the
kick is caught quickly enough, there is less danger of pipe sticking. If the pipe is off bottom
(making a trip, etc.) at the time of the flow, the pipe should be returned to bottom, if at all
possible. If necessary, it should be stripped in.
