Question 3285 Deck General

The correct answer is D) 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 helps control well pressure and prevent a blowout in the event of an unintended release of fluids from the well. The other answer choices are incorrect because: A) an accumulator is a pressure storage device, B) the annulus is the space between the wellbore and the casing or pipe, and C) an automatic choke is a device used to control well flow, not seal the annular space.
