What is a Christmas Tree?

A Christmas Tree is an assembly of valves, spools, and fittings placed on a producing well to control the flow of the fluid that comes out of the well (usually oil or gas), to transport oil/gas from well to pipeline or to control the injection of gas or water into the well to enhance its production.

How is it important to us?

Oil and Gas: Christmas TreeThe name comes from the fact that it resembles a decorated tree.

The Christmas tree and the wellhead should not be mistaken. The Christmas tree is installed on top of the wellhead to seal the annular space between the casing and the tubing.

Christmas tree can be used on both offshore and onshore wells and are therefore identified as subsea tree or surface tree.
