n: a choke in which the position of a conical needle, sleeve, or plate may be changed with respect to their seat to vary the rate of flow;may be manual or automatic. See choke.

n: A choke in which a conical needle and seat vary the rate of flow.

a pressure step-reduction choke that can be changed while actively flowing the well.

n: an adjustable choke that is power-operated to control pressure of flow. See adjustable choke.

n: The adjustable choke controled by pneumatics or hydraulic pressure. Used for controlling the pressure and circulating rate.

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: a choke whose opening is one size only, that is, not adjustable. Compare adjustable choke.

a non adjustable choke that uses a flow bean for regulation.

v: to decrease the size of the opening of an adjustable choke when a kick is being circulated out of a well.

n: a choke in which the orifice size must be changed to change the rate of flow through the choke.

typically a non adjustable choke using a flow bean.
