The SP™ tubing-retrievable safety valve (TRSV) is a single rod-piston non-elastomer flapper valve designed for hostile environments and extended life applications where ultimate reliability is required. Potential leak paths within the valve are minimized with the single rod-piston design. The piston achieves a metal-to-metal (MTM) seal at its uppermost and lowermost positions to seal well pressure from the control system. The SP valves incorporate flappers using spherical radius sealing surfaces that help greatly improve seal reliability. The spherical radius design provides full MTM sealing integrity. For applications where either the OD or ID is restrained, SP valves incorporate a contoured flapper. OD/ID relationships are improved by the contoured flapper design, which helps provide superior MTM sealing when compared to other forms of curved flapper technology. Applications » For applications requiring ultimate reliability and longevity, such as high-temperature/high-pressure, and subsea completions, or hostile well environments Features » Non-elastomer dynamic piston seals » MTM static seal at upper and lower piston positions » MTM body joints » Flow tube fluted guide » 100% MTM flapper » Concentric thrust bearing » Wiper ring on upper flow tube » Cleanout ports in flow tube’s upper end » Internal exercise profile » Flow tube shock absorber » MTM face seat at flow tube downstop » Setting depths to 9,000 ft (2743 m) » Critical components isolated from well debris with valve in open position » Area above flow tube free of solids buildup » Flow tube can be manipulated by slickline » Protected from high flow rate slam closures *information referenced from supplier catalog.

The FRN wireline-retrievable flapper valve, which is normally closed, is held open by hydraulic control pressure from the surface. The valve operates on a hydraulic-piston principle. To open, tubing pressure slightly higher than the well pressure below the closed flapper is applied. Once well pressure is equalized across the closed flapper, hydraulic pressure is applied to the piston, which pushes the flapper open. The flapper hinge assembly is designed so the force on the piston is not applied directly on the hinge pin. Upon loss of hydraulic pressure in the control line, the valve's large spring serves to lift the hydrostatic head of the control fluid. The flapper spring is designed to close the valve when the piston moves up past the flapper. Opening Prong Nose Seal The FRN valve uses the valve housing as the downstop for the opening prong. This metal-to-metal (MTM) interface is designed to prevent flow from passing between the valve housing and opening prong. The MTM interface isolates the flapper and seat from fluid flow while the valve is open. This design creates an MTM interface with the full force exerted by the hydraulic piston, minus the spring compression force, holding the two metal faces in contact. Radius of Curvature at Flow Entrance Halliburton conducted a study with various curvatures on the entrance to the valve. The study tested abrasive fluids flowing through different test subs and examined the resulting wear patterns. As a result, an optimum radius of curvature was determined and implemented on the valve housings of all wireline retrievable safety valves. Applications » New completions » Deep set » High pressure Features » High-strength rod-piston actuation » Non-equalizing flapper closure » Solid construction flapper made from bar stock » Spherical radius seat on flapper improves seal reliability » Sealing and seating surfaces are out of flow path of well production when valve is in open position » Designed for easy field servicing *information referenced from supplier catalog.

The WI retrievable injection valve is a high-performance, high-flow rate injection valve. High throughput is achieved by a unique valve configuration that minimizes turbulent and potentially erosive flow. Operation is not dependent on a specific flow rate, pressure, or setting depth, thus negating the need for adjustment over time. The valve incorporates a metal-to-metal valve and seat energized by the combination of an integral spring and well pressure acting from below. The WI injection valve can be deployed on a wireline lock or through-tubing pack-off device, providing flexibility not available with alternative injection valve systems. As a result of the simple design with fewer parts, redress and repair costs are considerably lower than those for other injection valve systems. Applications The WI injection valve is primarily used in water injection applications as an alternative to conventional tubing or wireline-set safety valves. The valve is also commonly used as a retrofit solution in water injectors in which a tubing to annulus leak has occurred. The valve can be deployed below the leak point to eliminate uncontrolled annulus pressure increases when the injection stops. Features » Compatible with all known lock systems » Dedicated designs to suit Halliburton EB0 intervention packers » Enhanced internal flow profile » Simple design and construction » Flow-loop testing performed to establish pressure drop versus pump rate *information referenced from supplier catalog.
