Choke drill<\/strong> is one of well control drills that will improve crew competency in driller\u2019s method. The advantages from the choke drill are as follows:<\/p>\n\n\n\n

\u2022 Get more familiar to practice controlling the pressure via a choke on the rig.<\/p>\n\n\n\n

\u2022 Get more understanding about lag time.<\/p>\n\n\n\n

\u2022 Practice the procedure to obtain the shut-in drill pipe pressure.<\/p>\n\n\n\n

\u2022 Ensure the surface well control equipment as pressure gauges, choke, BOP is ready for work.<\/p>\n\n\n\n

\u2022 Get more practices when attempting to bring the pump up to kill speed, slow the pump down and change the pump rate.<\/p>\n\n\n\n

Choke Drill Steps are listed below:<\/strong><\/p>\n\n\n\n

1. Trip in hole above top of cement.<\/p>\n\n\n\n

2. Fill the pipe and circulate seawater or mud around for few minutes.<\/p>\n\n\n\n

3. Close annular preventer or upper rams preventer.<\/p>\n\n\n\n

4. Pressure up annulus to 200 psi (the pressure may be different depending on the company policy.)<\/p>\n\n\n\n

5. Line up the pump.<\/p>\n\n\n\n

6. Pump slowly to bump the float and obtain shut in drill pipe pressure.<\/p>\n\n\n\n

7. Bring the pump to kill rate by holding casing pressure constant \u2013 personnel need to adjust the choke.<\/p>\n\n\n\n

8. Measure lag time for the drill pipe gage after the adjustment of choke is made.<\/p>\n\n\n\n

9. Change circulation rate by holding casing pressure constant. Crew needs to adjust choke to achieve this.<\/p>\n\n\n\n

10. Shut the pump down by holding casing pressure constant.<\/p>\n\n\n\n

11. Bleed off pressure and line up for drilling operation.<\/p>\n","protected":false},"excerpt":{"rendered":"
