Why did the blowout preventer fail in Deepwater Horizon?
The CSB concluded that the blowout preventer (BOP) failed because miswired control systems would have prevented it from sealing the blown-out well. A blowout preventer is a multi-ton stack of valves and pipes that sits atop deepwater wells to stop oil and gas from gushing upward in an accident.
What is the purpose of the blowout preventer and how does it work?
Essentially, a blowout preventer (BOP) shuts off the valve leading underneath the machinery to stop any liquid from surfacing in a dangerous explosion, or a kick. A level of containment must be maintained when working with the mud and substances that could cause breaks in the flow of extraction.
How many types of blowout preventers are there?
BOPs come in two basic types, ram and annular. Both are often used together in drilling rig BOP stacks, typically with at least one annular BOP capping a stack of several ram BOPs.
What is the difference between an annular preventer and a ram preventer?
So what’s the difference between annular BOPs versus ram BOPs? The annular BOP helps seal the space around the drill pipe (also known as annular space) during a “kick.” But, a ram BOP is designed to seal off a well when the drill pipe, tubing, or casing is in the well.
What is the difference between a kick and a blowout?
A kick is defined as flow of formation fluids or gas into the welbore, a blowout is the uncontrolled release of the fluid or gas, gained through the kick. A blowout can take place at the surface or into another formation( underground blowout).
What is annular blowout preventer?
An annular blowout preventer is a large valve designed to seal, control, and monitor oil and gas wells. These BOPs have elastomeric sealing, a valve resembling a large rubber donut, which mechanically squeezes inward to seal the drill string, casing, open hole, or pipe.
What is BOP oil and gas?
BOP is an abbreviation for Blowouw preventer. BOPs are considered as one of the most important and critical objects on a drilling rig as they are helpful in controlling the back pressure kick inside the wellbore.
