What is a BOP stack?

A BOP stack is one of two or more units which control well pressure, and contain the wellhead and blowout preventers. The equipment in the BOP stack provides the means to contain well pressures. The BOP stack is used to contain abnormal pressures in the well bore while drilling the well.

What is the function of a BOP?

A blowout preventer (BOP) (pronounced B-O-P, not “bop”) is a specialized valve or similar mechanical device, used to seal, control and monitor oil and gas wells to prevent blowouts, the uncontrolled release of crude oil or natural gas from a well. They are usually installed in stacks of other valves.

How does a BOP accumulator work?

A BOP accumulator unit (also known as a BOP closing unit) is one of the most critical components of blow out preventers. Accumulators are placed in hydraulic systems for the purpose of storing energy to be released and transferred throughout the system when it is needed to accomplish specific operations.

What is blowout preventer stack?

The blowout preventer assembly is mounted on the top of the casing head during drilling operations. Its purpose is to prevent the contents of the annulus from being aggressively emptied into the atmosphere when the bit drills into an unexpectedly high pressure zone.

How many types of BOP are there?

There are three main categories of the BOP: the current account, the capital account, and the financial account.

What is BOP piping?

Background. Bottom of Pipe (BOP) is often needed by designers to know the elevation at which the pipe wall ends/starts.

Where is BOP placed?

The BOP is located at the top of the well near the seabed and surrounds the pipe or drill string, which passes through it. The fact that the BOP surrounds the pipe and stays in place throughout the drilling operation means that it can be used at any time to shut in or seal off the well.

What is HCR valve?

The HCR valve is a hydraulically operated gate valve. This valve is used on diverter systems and choke/kill lines leading from the blow out preventers. The advantage of the valve is that it can be operated remotely.

What is the purpose of the blowout preventer and how does it work?

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. It works like a valve to close an oil well, similar to a plumber closing a valve in a pipe, and are proven to be highly effective in ensuring well safety.

What is BOP pressure?

A blowout preventer (BOP) is a large, high-pressure safety valve used to prevent the uncontrolled flow of liquids and gases during well drilling operations. Pressure control is a critical part of the drilling process, and, as a fail-safe component, a blowout preventer is essential to the safety of your rig.

What is BOP in drawing?

BOL – bottom of line. BOP – bottom of pipe.
