Wellhead and Christmas trees are vital in the oil and gas industry for controlling and managing oil and gas flow from a well. A wellhead is located at the surface and serves as the interface between the underground reservoir and extraction equipment. It supports the casing and tubing, regulates pressure, and allows for safe hydrocarbon extraction. The wellhead also holds various valves and gauges to monitor pressure, temperature, and fluid flow.

A Christmas tree, or wellhead Christmas tree, is a system of valves and pipes installed on the wellhead to control oil and gas flow. It regulates pressure and flow rate, giving operators control over production. The Christmas tree includes several key valves, such as the master valve, wing valve, and choke valve, which help manage well production and pressure. These valves are especially important for high-pressure wells.

Both wellhead and Christmas trees are crucial for safe and efficient oil and gas operations. They control pressure, prevent blowouts, and ensure smooth production processes.
