Wellhead Equipment


Wellhead equipment is used to connect the tubing and casing to an oil or gas pipeline. The casing is a permanently-installed pipe for lining the well hole to provide pressure containment and prevent collapse. The wellhead is a flanged device that attaches to the casing. It is used to suspend the casing strings and help seal the well.

Wellhead equipment includes components such as casing heads, casing spools, tubing head spools, tees, and crosses. The casing head is part of the connection between the casing and the wellhead itself. Typically, multiple pieces of wellhead equipment are integrated into a wellhead assembly called a "Christmas tree". This wellhead assembly allows tubes to be placed into the well while valves and chokes are used to control the flow of oil and/or gas at the surface.
