Well Control in Case of Offshore Blowout: Pump Mud from the Surface through the Drill Pipe and Back through the Annulus (Central Annulus Killing System)

摘要

Pumping mud from the surface is often used to stop blowout. Production phase blowout can with high probability be controlled by a new method based on pumping mud from a central system into the well via annulus. A feasibility study is recommended. Blowout can often be stopped if the well can be entered with drill pipe through which mud can be pumped. Several worth-while ideas aimed at facilitating this operation have been identified and recommended for further study.
