Surface Test Tree (Flow Head)

A Surface Test Tree, also known as a flowhead, is a piece of equipment used in the oil and gas industry. It is positioned directly on top of a well and serves as the first point of contact for fluids from the well. The main function of a surface test tree is to regulate the flow of fluid into and out of the well. It typically consists of gate valves, including a master valve, two wing valves, and a swab valve.

The surface test tree is crucial for well control during testing or intervention activities on a production well. It allows operators to control the flow of fluids and maintain the integrity of the well during various operations.
