The world’s first electric tubing-retrievable safety valve (eTRSV)

The Halliburton EcoStar® valve is the world’s first electric tubing-retrievable safety valve (eTRSV) and was the first installed in 2016. The EcoStar eTRSV solves a 30- year industry challenge to remove hydraulic actuation and its limitations.

This breakthrough in electric actuation is made possible through a unique magnetic coupling mechanism between the actuator and the safety valve. The design and construction of the valve creates a chamber for the downhole electronics and electric actuator outside of the wellbore.

This enables a fully electric completion system with zero risk of exposing electronics to produced wellbore fluid and the added benefit of serving as a conventional safety valve with the same trusted failsafe mechanisms.

World’s first electric tubing-retrievable safety valve

The valve eliminates hydraulic fluid to enable a fully electric completion system with zero risk of exposing electronics to produced wellbore fluids while retaining the same failsafe mechanism as today’s conventional safety valves.
