You calculate the final circulating pressure by dividing your new kill mud weight by the current mud weight and then multiply this value by the same dynamic pressure loss you used above. Fabrizio 1 year ago. IWCF also shares excellent kill sheets used for well control situation to everybody. It should not be ? Geoff 2 years ago.
Once the mud pump is slowly brought up to the kill rate speed, you need to take note of the Initial Circulating Pressure to make sure it is close to what you calculated on your kill sheet more on Kill Sheets in a bit.

Took a kick casing psi was psi 0psi on stand pipe for a long time, operator opened choke with out ever having a drill pipe pressure. It will be expected that you slowly stop the mud pump gradually slowing the pump maintaining casing and kill-line pressure.
Not only did Shset not know much about lining up sheef choke manifold or standpipe manifold, I knew virtually nothing about what RPM to drill at, how much pressure to maintain on the drillpipe or SPM on the mud pumpsformila much weight to maintain on the drill bit while drilling, etc. I had probably 10 of these problems on my IWCF Level 4 exam and they made up a very large percentage of my final score.
