7 1/16″ - 21 1/4″ Shaffer Annular Bop Oil Well Drilling

What is annular bop

Annular preventers are the most versatile well-control equipment and many names are referring to it as bag preventers or spherical preventers. The annular preventers can seal around several sizes of drill pipe/drill collar, work string, wireline, tubing, etc. There are some models which can utilize wellbore pressure to provide the additional sealing capability.

An annular blowout preventer helps keep the oil well-sealed to prevent disastrous blowouts. It operates differently from the ram blowout preventers.

Main components

Lower housing, upper housing, piston, adapter ring, and packing element. All components are designed and built for ease of maintenance and ultimate reliability.

How the annular preventers work

Close – When the hydraulic oil is pumped into the extended port, the element inside will be lifted and squeezed into the pipe/tubular.

Open – On the other hand, if the hydraulic fluid is pumped into the retract port, the element will be pushed down resulting in releasing the tubular.

Annular vs RAM Blowout Preventer

The annular blowout preventer performs several functions in drilling operations. It seals the annular space between the tubing, casing, and drill pipes. It also helps maintain the seal when the casing, tubing, or drill pipes are out of the drill hole. Unlike RAM blowout preventers, annular BOPs can seal various pipes of different sizes.
