What Is a Wellhead & Christmas Tree?

The wellhead is a critical component installed at the surface of an oil or gas well. It provides the structural and pressure-containing interface for drilling and production equipment. It suspends casing strings and ensures secure pressure control from the wellbore to surface systems.

The Christmas tree is installed after the wellhead during production. It consists of a system of valves, spools, chokes, and gauges that resemble a tree—hence the name. Its main function is to control the flow of oil or gas out of the well, while also enabling functions like pressure relief, chemical injection, safety control, and integration with electrical and hydraulic monitoring systems.

Together, the wellhead and Christmas tree form the backbone of safe, regulated extraction in oil and gas operations.
