RamType Blowout Preventer. A ramtype blowout preventer is basically a large bore valve (see Figure 1B). The ram blowout preventer is designed to seal off the well bore when drill pipe, casing, or tubing is in the well. In a BOP stack, ram preventers are located between the annular blowout preventer and the wellhead (see Figure 2B).
A large valve at the top of a well that may be closed if the drilling crew loses control of formation fluids. By closing this valve (usually operated remotely via hydraulic actuators), the drilling crew usually regains control of the reservoir, and procedures can then be initiated to increase the mud density until it is possible to open the BOP and retain pressure control of the formation.

3. Blowout Preventer System. If hydrocarbons unexpectedly flow into the well during drilling or other operations despite the use of primary barriers in the well, the blowout preventer (BOP) system serves as a secondary means of well control (, preventing undesired hydrocarbon flow from the well).
Oct 27, 2016· Anyone who wants to be wellversed in oil drilling must understand the crucial role of the blowout preventer (BOP). Understanding each component of a rig''s safety system means understanding how they work together, as well as their individual contributions, for efficient and safe operation. Essentially, a blowout preventer (BOP) shuts off the valve leading underneathRead more
The blowout preventer (BOP) that was intended to shut off the flow of highpressure oil and gas from the Macondo well in the Gulf of Mexico during the disaster on the Deepwater Horizon drilling rig on April 20, 2010, failed to seal the well because drill pipe buckled for reasons the offshore drilling industry remains largely unaware of, according to a new twovolume draft investigation report ...
