Blowout Preventers (BOP)

Blowout Preventers (BOP)

Blowout preventers

Blowout preventers are large, high-pressure valves that are capable of being remotely controlled. When the driller closes the valve, a pressure-tight seal is formed at the top of the well, preventing the fluids from escaping. There are two major types of Blowout Preventers, Annular (also known as Spherical) and RAM. Annular BOPs are usually mounted to the very top of the BOP stack. The drilling crew then mounts two, three, or four RAM BOPs below the Annular preventer. If a kick is detected, the annular is usually closed first and then the RAM is used as a backup if the Annular should fail.

Blowout preventers are used on land wells, offshore rigs, and subsea wells. Land and subsea BOPs are secured to the top of the wellbore, known as the wellhead. BOPs on offshore rigs are mounted below the rig deck. Subsea BOPs are connected to the offshore rig above by a drilling riser that provides a continuous pathway for the drill string and fluids emanating from the wellbore.

AWALTEK’s BOP products fall into two large product series: Drilling BOP and remedial well treatment as well as Operation BOP, covering 200 models and specifications. This products is applicable in a variety of operation conditions include, formation testing and down hole operation in low temperature, high temperature and high content of sulphur, and they can fully satisfy the well control requirements in drilling operations, underbalanced drilling, formation testing and down hole operation.
