a tubing safety valve.

a well is considered “stabilized” when, in the case of a flowing well, the rate of production through a given size of choke remains constant, or, in the case of pumping well, when the fluid column within the well remains constant in height.

a storm choke

in well-control operations, closing the BOP’s with the choke and HCR, or fail-safe, valves open. Compare hard shut-in.

a bottomhole choke run on wireline and landed in a nipple profile in the tubing string.

a set of controls, usually placed on the rig floor, that is manipulated to control the amount of drilling fluid being circulated through the choke manifold. This procedure is necessary when a kick is being circulated out of a well. See choke manifold.

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