Pchok© becomes at the start of circulation Pan ( at the kill line gauge), and MAASP is the static MAASP (at the kill line gauge) At the end of the circulation it could be possible thatp2 mud is on surface through the choke line andpj mud is still in the kill line [method 2 under item (4 ] Both choke and kill lines have been used to circulate out the kick

Well kill - Wikipedia

A well kill is the operation of placing a column of heavy fluid into a well bore in order to prevent the flow of reservoir fluids without the need for pressure control equipment at the surface. It works on the principle that the hydrostatic head of the "kill fluid" or "kill mud" will be enough to suppress the pressure of the formation fluids. Well kills may be planned in the case of …

9.2.5: The Well Control System (Blowout Prevention System

The Well Control System or the Blowout Prevention System on a drilling rig is the system that prevents the uncontrolled, astrophic release of high-pressure fluids (oil, gas, or salt water) from subsurface formations. These uncontrolled releases of formation fluids are referred to as Blowouts.Due to the explosive nature of oil and gas, any spark on the surface can result in the …

1.Close the surface kill line valve and open the kill line valve at the BOP stack. 2.Wait until mud from the kill line is replaced with gas. This will be indied when kill-and choke line pressures are equalised. 3.Pump a small amount of mud 0.3-0.6 m3 (2-4 bbl) into the kill line and let the kill- and choke line pressures equalise.

A method for a dynamic shut-in of a subsea mudlift drilling system. The method comprises detecting a kick, isolating a wellbore, and adjusting a subsea mudlift pump and a surface mud pump to provide a selected wellbore pressure. Selected well parameters are measured and used to calculate a kick intensity. The invention is also a method for a dynamic shut-in of a subsea …

Choke Line - an overview | ScienceDirect Topics

The kill line must have a working pressure equal to or greater than the ram BOP in use. • Two full bore manual valves plus a check valve, or a manual valve and a hydraulically actuated valve between the BOP stack and the kill line are recommended for systems with a rated working pressure more than 5000 psi. •

kill line | Oilfield Glossary

kill line. 1. n. [Drilling] A high- pressure pipe leading from an outlet on the BOP stack to the high-pressure rig pumps. During normal well control operations, kill fluid is pumped through the drillstring and annular fluid is taken out of the well through the choke line to the choke, which drops the fluid pressure to atmospheric pressure.

A tool driver activates a telemetry tool when a predetermined threshold of accelerometer data measured by an accelerometer. The threshold preferably corresponds to an acceleration level expected while drilling mud is pumped at a slow pump rate through the well''s drill pipe. When a fluid influx occurs during drilling, the well is shut-in, and the tool driver turns off the telemetry tool.
