Definitions for blowout preventer
This page provides all possible meanings and translations of the word blowout preventer
a device that sits at the surface interface of an oil well, that prevents a blowout from occurring, by closing the orifice allowing material to flow from the oil reservoir out through the shaft.
A blowout preventer is a large, specialized valve or similar mechanical device, usually installed redundantly in stacks, used to seal, control and monitor oil and gas wells. Blowout preventers were developed to cope with extreme erratic pressures and uncontrolled flow emanating from a well reservoir during drilling. Kicks can lead to a potentially catastrophic event known as a blowout. In addition to controlling the downhole pressure and the flow of oil and gas, blowout preventers are intended to prevent tubing, tools and drilling fluid from being blown out of the wellbore when a blowout threatens. Blowout preventers are critical to the safety of crew, rig and environment, and to the monitoring and maintenance of well integrity; thus blowout preventers are intended to be fail-safe devices. The term BOP is used in oilfield vernacular to refer to blowout preventers. The abbreviated term preventer, usually prefaced by a type, is used to refer to a single blowout preventer unit. A blowout preventer may also simply be referred to by its type.
