Abstract

A system for containing and recovering from the blowout of an oil or gas well. The blowout containment (BOC) system is operable in place of, or as a failsafe alternative to, standard blowout preventer (BOP) systems. The BOC system includes a hydraulically operated gate valve positioned over the well at the wellhead. The gate valve includes a check valve operable when the gate valve is closed. The BOC system further includes at least one shearing assembly positioned over the gate valve. The shearing assembly orients explosive charges into the well flow path. An activation trigger detonates the explosive charges to clear the well flow path of obstructions to permit the gate valve to close. Operation of the BOC system is preferably monitored and controlled from a remote location apart from the rig associated with the well.
