Abstract
The method of preventing pressures higher than a predetermined pressure in the front ram seals of blowout preventer rams comprising providing blowout preventer rams suitable for sealing across the bore of a blowout preventer stack, providing seals on the blowout preventer rams which sealingly isolate the bore area below or upstream of the blowout preventer rams from the area above or downstream of the blowout preventer rams, providing a passageway from the front to the rear of the blowout preventer rams to vent the upstream or higher pressures to the rear of the blowout preventer rams, and communicating the resilient seal material in the front ram seals with a pressure release piston which will relieve the pressure at the predetermined pressure.
