What is an annular BOP?

What is an annular BOP?

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.

How tall is a BOP?

Blowout Preventer – The 5M double ram BOP is just over 4 feet (1340 mm) in height and weighs under 14,000 pounds (6019 los) allowing use in workover and the largest drilling rig operations. Ram blocks are available, as standard, from Blind thru 8.63″ ( 219.2 mm).

What is a BOP ram?

A ram BOP is a blowout preventer that uses a pair of steel plungers that oppose each other (rams). The rams can extend towards the wellbore’s center to restrict the flow of fluids or retract open to permit the flow.

What is the normal closing pressure range for an annular preventer?

between 1000 and 1500 psi
The pipe rams and annular preventer are individually tested by closing them on the drill pipe and pressuring up through the kill line or drill string. Pressures involved for testing the surface casing and preventers are between 1000 and 1500 psi.

How heavy is a BOP?

As a result, BOP assemblies have grown larger and heavier (e.g. a single ram-type BOP unit can weigh in excess of 30,000 pounds), while the space allotted for BOP stacks on existing offshore rigs has not grown commensurately.

How big is a blowout preventer?

A blowout preventer, or BOP, is a large specialised unit weighing up to 400 tonnes that is used to prevent an oil spill from occurring.

What is a Hydril BOP?

A Hydril is one of the types of blowout preventers (BOP’s) that is a specialized valve which is used to prevent blowout while monitoring, controlling, or sealing oil and gas wells. The annular blowout preventer is known as Hydril, which is named after one of the manufacturers of the device. (

What is a BOP soak test?

Soak testing (otherwise known as endurance testing, capacity testing, or longevity testing) involves testing the system to detect performance-related issues such as stability and response time by requesting the designed load on a system. Soak testing is a type of load testing.

How big is the annular BOP weights catalog?

Why choose a high pressure annular BOP?

Cameron DL high-pressure annular BOPs allow reliable performance in a shorter height and lighter weight than comparable annular BOPs. The unique design of our DL BOP does not require wellbore assist. The annular can close on drillpipe or large tubulars without reducing operating pressure, which minimizes risk of indention or damage to casing.

What is the maximum hydraulic pressure required for Bop operation?

The normal 1,500-psi hydraulic pressure is the maximum required for BOP operation over the full 10,000-psi working pressure range. Configuration has a studded body for quick removal of the bonnet and rapid packer removal
