Electric Safety Valves

The eValve™ Story


Camco* Products & Services built the first eValve under license from the original inventors in the mid 1970s. There have been 12 or more installations of this valve design in wells over the years, deployed by Camco. At that point in its history Camco was the world leader in the hydraulic SCSSV market and subsequently made a business decision not to pursue further development of the eValve believing it was consuming its own market. Deep set SCSSV applications at that time were non-existent. As a result, assignment and ownership of eValve returned to the original inventor/licensors. With recent renewed industry interest in electric SCSSVs for deep set applications, the owners of the eValve contacted Tejas about bringing it up to current industry standards.

Electric Safety Valve Technical Sheet

The Tejas tubing retrievable injection valve, or TRIV™, is a subsurface controlled, injection safety valve that features the patent-pending Tejas VOi™ variable orifice insert. It is designed to prevent injection fluid from flowing back out of the well if the surface control system becomes damaged or malfunctions. The TRIV also provides pressure management as the surrounding reservoir wells are produced.

HPHT Safety Valves

The Tejas HPHT Tubing Retrievable Surface Controlled Subsurface Safety Valve (SCSSV) is a 25,000 psi rated working pressure, non-equalizing, xHPHT safety valve. It is designed to minimize the loss of reservoir fluids or production equipment by shutting in the well in the event a catastrophic surface or subsurface event were to occur.

The patent-pending Tejas TRIS™ is a dual barrier tubing retrievable injection sleeve system featuring the VOi™ variable orifice choke and is designed for multi-zone injection. The TRIS™ is similar to conventional sliding sleeves that have an inner sleeve shifted open to establish communication/injection from the tubing to the annulus/formation. Unlike conventional sliding sleeves which are shifted mechanically (via wireline or coiled tubing shifting tools) the TRIS™ is shifted open with differential pressure from flow alone. When injection is suspended, the TRIS™ and VOi™ return to the closed position, providing dual barrier protection, one from below the VOi™ and the second from the annular space behind the TRIS™.

Large Bore Safety Valves

The Tejas TRCF series surface controlled subsurface safety valves (SCSSV) are rated to 10,000 psi [68,948 kPa] working pressure at 350deg F [176.7degC]. TRCF valves are designed to automatically shut in the well and prevent unrestricted well flow in the event of a catastrophic surface or subsurface event.

This valve is a rod piston actuated, normally closed, fail-safe safety valve which is held open with control pressure supplied from the surface by an emergency shut-down (ESD) system to a hydraulic control line that connects to the valve. Loss of control line, ESD system, pressure returns the valve to the closed postion.

The Tejas TRSV is a 5,000 psi rated working pressure, safety valve with a self-equalizing option. It is a rod piston actuated, normally spring closed, fail safe, safety valve which is held open with independent control pressure supplied from the surface by a hydraulic control line that extends through the wellhead to an emergency shut-down (ESD) system at the surface. Removing the control line pressure will return the valve to its normally closed position.
