Patent Drawing of a Subsea BOP Stack (with legend) 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.
Offshore drilling rigs have similar elements, but are configured with a number of different drilling systems to suit drilling in the marine environment. The equipment associated with a rig is to some extent dependent on the type of rig but typically includes at least some of the items listed below.
Drilling rig; 2. Rock layers; 3. Oil rigs; 4. Oil and natural gas. Oil platform Mittelplate in the N. An oil platform (also called an oil rig, offshore platform, oil production platform, etc.) is a large structure with facilities to extract and process petroleum and natural gas that lie in rock formations beneath the seabed.
Blowout (well drilling) The Lucas Gusher at Spindletop, Texas (1901) A blowout is the uncontrolled release of crude oil and/or natural gas from an oil well or gas well after pressure control systems have failed. [1] Modern wells have blowout preventers intended to prevent such an occurrence. An accidental spark during a blowout can lead to a ...
An auxiliary power unit ( APU) is a device on a vehicle that provides energy for functions other than propulsion. They are commonly found on large aircraft and naval ships as well as some large land vehicles. Aircraft APUs generally produce 115 V AC voltage at 400 Hz (rather than 50/60 Hz in mains supply), to run the electrical systems of the ...
A drilling rig is an integrated system that drills wells, such as oil or water wells, or holes for piling and other construction purposes, into the earth's subsurface. Drilling rigs can be massive structures housing equipment used to drill water wells, oil wells, or natural gas extraction wells, or they can be small enough to be moved manually ...
Comparison of deepwater semi-submersible (left) and drillship (right) A semi-submersible platform is a specialised marine vessel used in offshore roles including as offshore drilling rigs, safety vessels, oil production platforms, and heavy lift cranes. They have good ship stability and seakeeping, better than drillships.
Subsalt: Refers to oil prospects that lie below a salt layer. [7] Toolhand: Refers to a third party (down hole services provider) service representative or field service supervisor with "tools" to be run and operated in a well. Toolpusher: The boss of a drilling rig, working under the drilling superintendent or the corporation the rig is ...
