n: a pressure gauge usually used in lines or manifolds.

n: A kind of afflux pipe with several imports and valves, used for cementing and connecting several cement injection lines. Controlling pressure and circulating rate and sending cement slurry to cement head.

n: a panel or board on the rig floor, usually near the drillers position, that allows a person to remotely adjust the size of the opening of a choke installed in the choke manifold. By adjusting the chokes opening, the operator can increase or decrease the amount of back-pressure being held on the well by the choke. Usually, the panel also has pressure gauges and other instruments to help the operator control the well.

n: a pipe attached to the blowout preventer stack out of which kick fluids and mud can be pumped to the choke manifold when a blowout preventer is closed in on a kick.

n: A high-pressure pipe leading from an outlet on the BOP stack to the backpressure choke and associated manifold. During well-control operations, the fluid under pressure in the wellbore flows out of the well through the choke line to the choke, reducing th

a drilling and workover pressure control device. A line that attached to the BOP stack and through which kick fluids can be circulated when the BOP is closed.

n: an arrangement of piping and special valves, called chokes. In drilling, mud is circulated through a choke manifold when the blowout preventers are closed. In well testing, a choke manifold attached to the wellhead allows flow and pressure control for test components down- stream.

n: A set of high-pressure valves and associated piping that usually includes at least two adjustable chokes, arranged such that one adjustable choke may be isolated and taken out of service for repair and refurbishment while well flow is directed through the

a set of valves and/or chokes used to control drilling fluid returns on a drilling well or, in a few cases, used to control flow from a high rate well where the chokes may be in parallel or series.

n: see insert.

n: Usually refers to polycrystalline diamond or diamondite. Including manifold shapes, usually cylindrical. Used as the cogging of diamond bit or cone bit.

n: the well pressure manifold and the throttle manifold connected to blowout hookup at the well head

n: a device installed in a flow recorders manifold to collect liquid that may condense out the gas in the manifold and to minimize the chance of inaccurate differential and static readings caused by liquid in the manifold lines.

n: the collar cross with two vertical through hole,used to dual completion
