Attribute

WEQ Well Equipment

Definition

An assembly of valves, spools, pressure gauges and chokes fitted to the wellhead of a completed well to control production.

Description

The christmas tree also incorporates facilities to enable safe access for well intervention operations such as slickline, electric wireline or coiled tubing. Its function is to both prevent the release of petroleum or gas from a well into the environment and also to direct and control the flow of formation fluids from the well. When the well is ready to produce petroleum or natural gas, valves are opened and the release of the formation fluids is allowed through a pipeline leading (eventually) to a refinery.
