Wellhead
From Wikipedia, the free encyclopedia
A wellhead is that part of an oil well which terminates at the surface, whether on land or offshore, where petroleum or gas hydrocarbons can be withdrawn.
A wellhead consists of the spools, valves, and other components which contain the pressure within the well. It also serves as a facility for installing casing hangers as well as christmas trees and other production control devices.
