Examples of Blowout preventer in a sentence

• The following shall be entered in the daily driller’s log: 1) Blowout preventer pressures tests, including test pressures and results.

• Blowout preventer A special assembly of heavy-duty valves, commonly called the BOP stack, installed on top of a well which can be closed to prevent high-pressure oil or gas from escaping (a blowout) from the well hole during drilling operations.

• GLOSSARY OF TERMS Blowout preventer: A series of valves installed on the wellhead to prevent the escape of pressure either in the annular space between the casing and tubing or drill pipe or in open hole during drilling or completion operations.

• This was a dangerous situation which was eventually remedied with the invention of the BOP (Blowout preventer) in 1922 by the founders of Cooper Cameron.3However, in spite of the development of many safety measures such as the aforementioned BOPs, as well as numerous types of equipment and drilling procedures, blowouts still occur.

• By closing BOP valves (commonly operated remotely via hydraulic actuators), the drilling crew often regains control of the reservoir and procedures can then be initiated to increase the mud density until it is possible to open the BlowOut Preventer and retain pressure control of the formation.Fig.3.36, 3.37 Blowout preventer (Pipingonline, 2019, Geodesicdrilling, 2019).
