v: To stop drilling or production operations when it becomes unprofitable. A wildcat may be abandoned after poor results from a well test. Cement plugs are placed in the wellbore to prevent fluid migration between different zones.

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: the tools used to carry out the well complete operation ,such as the scoop out tool, casing perforation tool and tool for completion well test and so on

gas to surface.

n: a productivity curve piotted when a well has two-phase flow. both oil and gas. based on well tests or a combination of computations and well tests. Also called IPR curve.

n: a device, including

n: the maximum volume of oil or gas that a well is capable of producing, calculated from well test data.

pressure test.

n: in surface well testing, a temporary set of valves installed for flow control on a wellhead with no Christmas tree.
