As per previous topic, driller’s method well control, it stated about overall of driller method and this post will show the detailed of driller’s method and describe in term of operation stand point as well. I separates all detailed-step of driller method into several blog post because I want to add a lot of details for each topic so you will clearly understand about driller method and you also can apply with your real life operation.
Today I will start with the first one is to shut in well and obtain pressure information
1. Shut in the well and get pressure data
After the well is shut-in with proper shut in procedures (read more about shut in procedures), personnel must take few minutes until the shut-in pressure to stabilize. Both the drill pipe and the casing gauge will dictate if the well stabilizes. While waiting for the well to stabilize, crew can have a chance to check everything is ready for killing operation as well.
After the well stabilizes, you will know how much shut in casing pressure (SICP) and shut in drillpipe pressure (SIDPP). However, if your BHA has a float inside, you will not see the SIDPP yet hence you must bump the float in order to get the SIDPP.
You may need to review the float bumping procedure to obtain shut-in drill pipe pressure.
After passing these steps above, you get the SIDPP and SICP.
