Tubing Safety Valve

Definition - What does Tubing Safety Valve mean?

A Tubing Safety Valve is a valve that enables the configuration of the internal components during a completion process. It can be retrieved as a main component of the production tubing string. The valve offers leak resistance to maintain the internal or external pressures and is also compatible with other fluids. It is designed to run in hostile environments so as to extend life applications of devices. The technical name for the tubing safety valve is "Tubing-Retrievable Safety Valve".

Petropedia explains Tubing Safety Valve

Tubing Safety Valves are usually present in oil or gas wells and are unidirectional in order to avoid the backward flow of wellbore fluids. They are installed in tubing strings so as to maximize the flow area and permit wellbore access from the coiled tubing. The main function of a tubing safety valve is to provide high volume capability and reduce the back pressure on the formation during the completion process. Moreover, the valve is the external control line used to secure the running string for the surface control system. As the valve is designed to protect the tubing string it should be made in accordance with the API and ISO standards.
