F- Bleed off pressure at the choke = the hydrostatic pressure of pumped mud. G- Repeat the above process till all the gas has been replaced with mud

DrillingForGas - Well Control - Preliminary record of

This practice will facilitate speedy well killing operations. Preparing kill mud in advance is recommended for wells in which increased mud weights are expected to be used. The recommended kill mud gradient depends on the expected formation pressures to be encoutered, but as a general rule may be 10-20% higher than the actual mud weight in use

DrillingForGas - Well Control - Balanced Mud Method

3.6 Well control with a Top Drive System (TDS) It is possible to avoid the necessity to take the choke line pressure drop into account during well killing operations by using the kill line as a pressure conduit to monitor Pa at the subsea BOP stack (kill line fail safe valves open and the kill line valve upstream of the choke closed). Normal well killing practices can then be …

Determining the best well-control method for most situations involves several considerations including the time required to execute the kill procedure, the surface pressures from the kick, the complexity relative to the ease of implementation, and the downhole stresses applied to the formation during the kick-killing process. All points must be analyzed before a procedure can …

Subsea Well Control Initial Circulating Pressure Use Scr

When killing a well from a floater, 6. Pressure loss through the choke line. The deeper the water, the greater this choke line friction pressure loss, and the more significant it becomes. In summary, the choke line pressure loss is always added to the annular pressure loss whenever circulation is from the bottom of the hole to the surface, through the choke line. For example: …

Well control with one-circulation method - PetroWiki

Shut down the pumps and close the choke after the kill mud has reached the flow line. The well should be dead. If pressure remains on the casing, continue circulation until the annulus is dead. 10. Open the annular preventers, circulate and condition the mud, and add a trip margin when the pressures on the drillpipe and casing are zero. In subsea appliions, the trapped gas under …
