Blowout preventers (BOPs) enable rig crews to contain unexpected flow and high pressures during drilling and production.
17 de feb. de 2015 · The blowout preventer (BOP) equipment on a rig serves as a backup to the mud system in controlling kicks and subsequent blowouts. Well kicks are prevented by maintaining the hydrostatic pressure of the drilling fluid greater than the formation pressures that are exposed to the wellbore.
The Well Control System or the Blowout Prevention System on a drilling rig is the system that prevents the uncontrolled, catastrophic release of high-pressure fluids (oil, gas, or salt water) from subsurface formations. These uncontrolled releases of formation fluids are referred to as Blowouts.
The function of the blowout prevention system is to control the movement of kick fluids (formation fluids that enter the wellbore) during drilling, tripping, and casing operations.
A blowout preventer ( BOP) (pronounced B-O-P) [1] is a specialized valve or similar mechanical device, used to seal, control and monitor oil and gas wells to prevent blowouts, the uncontrolled release of crude oil or natural gas from a well. They are usually installed in stacks of other valves.
1 de jul. de 2020 · Subsea blowout preventer (BOP) is a safety-related instrumented system that is used in underwater oil drilling to prevent the well to blowout. As oil and gas exploration moves into deeper waters and harsher environments, the setbacks related to reliable functioning of the BOP system and its subsystems remain a major concern for ...
Introduction. Preventing and, when prevention is not suficient, respond-ing to potential uncontrolled releases of oil or gas ("blow-out") is critical to safe drilling operations. A kick is an influx of formation fluids into the wellbore. A blowout is an uncon-trolled kick exiting the well at surface.
