1. Kill Procedure
a.Shut-in the well immediately using the appropriate shut-in
b. After the pressures have stabilized, read and record the
shut-in drill pipe pressure, the shut-in casing pressure, and
the pit gain.
c. Check the drill pipe for trapped pressure.
d. Calculate the exact mud weight necessary to kill the well
e. Mix the kill mud in the suction pit.
f. Prepare a kill sheet.
g. Initiate circulation by adjusting the choke to hold the
casing pressure at the shut-in value while the driller starts
the mud pumps. Copyright(c) 2005 by Ali Ghalambor & Boyun Guo 46 h. Use the choke to adjust the pumping pressure
according to the required pressures from the kill
i. Shut down the pumps, close in the choke and
record pressures . The drill pipe pressure should
