Blowout Preventer

How do blowout preventers work?

They are used on the wellhead as a safety precaution, so that if the well attempts to blowout, it can be controlled. Most of them today are hydraulically operated. Essentially, a blowout preventer (BOP) shuts off the valve heading below the equipment to halt any liquid from appearing in a dangerous explosion, or a kick. A specific level of containment must be sustained while working with the mud and materials that could create breaks in the flow of extraction. There are numerous features in a BOP that make up the whole and two kinds of valves that assist the apparatus in case there is a bad kick.

An annular BOP closes the space around the width of the pipe. The actual system cannot be closed with a valve because of the drill string, so the annular controls the air flow for the mud without cutting off any other systematic elements. The annular BOP provides the most efficient airtight option and is put on the top of the BOP stack. A RAM BOP also works to thwart any unwanted materials from exploding in the system. Several at a time are used in the BOP stack to safeguard optimal safety.

What are Blowout Preventers (BOP Systems)?

A blowout preventer is a large, heavy valve or stack of valves fitted at the top of an oil well. Blowout preventers are used to seal, control and monitor oil and gas wells to prevent the release of oil or gas from wells and rigs.

There are two main types of blowout preventers: Annular and RAM. An annular blowout preventer is usually mounted at the top of the stack with two to four RAM blowout preventers mounted below for backup.

Oil and Gas Blowout Preventers

A donut-shaped rubber packing element is used as the sealing device in blowout preventers. These can be exposed to different drilling environments and temperatures, so the rubber component must be able to withstand drilling liquids, mud and heat to operate efficiently and without problems.
