Method of dynamically killing a well blowout
Patent
·
OSTI ID:6797132
A process for dynamically killing a well blowout by means of a relief well is claimed. A low density fluid is pumped down the relief well and into the blowout well at a rate to produce a frictional pressure loss in the blowout well which when added to the hydrostatic pressure in the blowout well is greater than the static formation pressure but less than the formation fracturing pressure. Injection of the low density fluid is continued until the blowout well goes from two-phase to single-phase flow. Thereafter, a high density fluid such as a drilling mud is pumped down the relief well and into the blowout well. This fluid produces a hydrostatic pressure in the blowout well which is greater than the static formation pressure.
