Question 2821Deck General70% to pass
A large valve, usually installed above the ram preventers, that forms a seal in the annular space between the pipe and wellbore or, if no pipe is present, on the wellbore itself is called the _______________.
AI Explanation
The correct answer is C) annular blowout preventer.
The annular blowout preventer is a large valve installed above the ram preventers that forms a seal in the annular space between the pipe and wellbore, or on the wellbore itself if no pipe is present. This device is a critical component of the blowout prevention system on oil and gas wells, as it can quickly seal off the well in the event of a well control incident.
The other answer choices are incorrect because: A) an accumulator is a pressure storage device, B) the annulus is the space between the well casing and the drill pipe, and D) an automatic choke is a device used to control wellbore pressure, but is not the same as an annular blowout preventer.
