Detailed Description

The DepthStar® tubing-retrievable safety valve (TRSV) is a revolutionary concept in the realm of surface controlled subsurface safety valves. Unlike other TRSVs, the DepthStar valve functions completely independent of well pressure; therefore, it is able to operate at consistently low hydraulic pressures, making it an ideal solution for deepwater completions. Previously, solutions to wellbore isolation of the piston required additional seals and/or gas-charged chambers where their reliability is heavily dependent on elastomeric seals and the permanent, long-term containment of a dome charge. The DepthStar valve, through the use of a revolutionary magnetic coupler, allows for positioning the hydraulic actuator completely out of the tubing wellbore. By repositioning the hydraulic actuator outside the tubing wellbore, the DepthStar valve becomes the world’s first 100% metal-to-metal (MTM) safety valve that contains no moving seals within the tubing wellbore. This reduction in seals combined with an intrinsically simple design makes the DepthStar TRSV inherently reliable. The DepthStar TRSV operates with a low operating pressure, making it an ideal solution for deep-set applications. Features » No moving seals exposed to the tubing wellbore » 100% MTM sealing within the tubing wellbore » Less than 5,000-psi maximum valve opening capability regardless of setting depth or pressure » Minimized number of body connections » Proven MTM, non-elastomer hydraulic actuator » Isolated flow tube *information referenced from supplier catalog.
