Halliburton launches new EcoStar electric tubing-retrievable safety valve (eTRSV)

Halliburton has launched an updated version of its EcoStar electric tubing-retrievable safety valve (eTRSV)

This second-generation product builds on the success of the industry’s first electric TRSV, first installed in 2016, which solves a 30-year industry challenge to remove hydraulic actuation and its limitations from safety valve systems.

Hydraulic systems in subsea wells are associated with high costs and potential health, safety, and environmental (HSE) risks. Subsea hydraulic systems are often complex, difficult to install, and expensive. Hydraulic fluid release and high-pressure surface equipment can be hazardous to personnel and the environment. The complex nature of subsea hydraulic systems can result in reliability challenges and slow hydraulic cycle times, which can cause production deferrals.

Halliburton’s all-electric safety valve represents an advancement in safety valve technology, enabling the removal of the hydraulics system. 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 the elimination of the risk of exposing electronics to produced wellbore fluid and the added benefit of serving as a conventional safety valve with the same trusted fail-safe mechanisms, closing in case of well incidents at the surface to safeguard personnel and the environment. It features independent and redundant electro-mechanical actuation and control systems, which enable more precise control, real-time position sensing, and valve health monitoring at the surface.

The new product reduces the need for extensive surface facilities, which streamlines operations and enhances personnel safety and field economics.

“As part of Halliburton’s all-electric portfolio, the EcoStar eTRSV marks another step toward the full electrification of wellbores. The EcoStar eTRSV builds on industry-leading safety valve technology to improve completion performance and maximise asset value for operators,” said Maxime Coffin, vice president, Halliburton Completion Tools.
