THE END
A GENERAL WELL KILL PROCEDURE FOR "WAIT & WEIGHT METHOD" USING SURFACE BOP STACK 1. Increase mud weight in active pits to KILL WEIGHT. 2. Zero stroke counters. Start pump and simultaneously open choke. Pressure on the choke initially should be the shut-in casing pressure and this pressure should be maintained while the pump rate is brought up to the kill rate. 3. HOLD PUMP RATE CONSTANT and adjust choke so that the drill pipe pressure follows the above schedule. If drill pipe pressure is too high, open the choke slightly; if it is too low, close choke slightly. 4. After the Kill Mud has filled the drill pipe, MAINTAIN CONSTANT PUMP RATE and CONSTANT DRILL PIPE PRESSURE until the annulus is filled with the kill mud. 5. When kill weight mud reaches surface, stop pump and shut well in. At this time, the casing pressure and drill pipe pressure should be zero. If some pressure still exist on casing, open choke slightly and bleed a small amount or volume of mud. If the well is dead, pressure should fall to zero and the flow should stop.
