Post Shut-In Procedures While Tripping -What data should be recorded?

After you complete shut in procedure while tripping, there is following information that must be recorded before making any decision on how to kill the well.

tripping

Shut-In Casing Pressure (SICP): Read and record the shut-in casing pressure (casing gauge).

In order to get the proper pressure reading, the casing gauge should be installed upstream of the closed choke.

Pit Gain: Read and record the pit gain. Pit volume gained is very critical for the maximum casing pressure calculation.

Practically, while tripping out of hole, a trip tank is used to track displace volume in use. The accurate pit gain value can be easily figure out by finding difference between actual volume taken to fill up wellbore and theoretical fill up volume. However, if the active pits are used to record the displacement volume, it will be very difficult to figure out the accurate pit gain. The concept of determining the pit gain is the same as using the trip tank. However, the reason that I say that it is very difficult to get the accurate pit gain because pit volume is too large to record few changes while tripping.

Time: Record the time that the well control situation is occurred and keep an accurate time log for the entire well kill operation

Bit Depth: Record bit depth.

Reference book: Well Control Books

    1. What will be the best way to calculate kick tolerance accurately?
    2. what short formula can you use to convert pressure to feet.
    3. In deep water drilling, what will be the easiest or the fastest formula or ways to calculate hang off point for mixed drill string component and assuming that your hang-off is on upper pipe rams?

    • 1. There are seveal assumptions that will apply into the kick tolerance calculation. I cannot tell you exactly which way is the most accurate one. Each company may have their own assumptions for this calculation.
      2. ft in TVD = Pressure (psi)/(0.052xMW (ppg))
      3. For this one, I don’t know but I will find out for you and will post into my blog in the future.
