Halliburton has developed the EcoStar electric tubing-retrievable safety valve (eTRSV).
This is a further development of the company’s initial electric TRSV, which won the Offshore Technology Conference’s Spotlight on New Technology Award in 2017.
The EcoStar eTRSV acts as a fail-safe that closes should well incidents occur at the surface.
Its field-proven magnetic coupling technology, Halliburton says, replaces the hydraulic actuation system with electric actuation. This design provides greater reliability by isolating the actuation system from completion tubing fluid and pressure, the company adds.
Its independent and redundant electro-mechanical actuation and control systems are also said to facilitate more precise control, real-time position sensing, and valve health monitoring at the surface.
The valve’s design and construction create a chamber for the downhole electronics and electric actuator outside of the wellbore. This, Halliburton continues, enables a fully electric completion system without the risk of exposing electronics to produced wellbore fluid—also serving as a conventional safety valve with the same fail-safe mechanisms.
