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.

The manufacturer has applied the same stringent testing used on its maximum reliability tubing-retrievable safety valves (TRSV) to its BigBore™ wireline-retrievable safety valve (WLRSV). This valve offers the durability and reliability of TRSVs through metal-to-metal (MTM) sealing of the contoured flapper, enhanced body connections, and debris isolation. The contoured flapper provides a large ID compared to other valve designs, while providing enhanced flapper sealing. Another significant feature of this valve is its ease of on-location servicing. The construction of the upper end of the valve provides for easy access to the valve’s external packing. Once the lock is removed, the packing retainer sleeve can be removed and serviced. The savings made possible by an enlarged ID, enhanced performance, and ease of service have made it an excellent choice for replacing equipment currently installed in existing completions. Applications » New completions » Replacement of existing WLRSVs to provide increased ID and reliability Features » MTM sealing contoured flapper closure with large ID » High-strength rod-piston actuation » Dual-sealing minimized body connections » Enhanced debris isolation through MTM interface of flow tube/bottom sub » Radius of curvature at flow entrance » Equalizing feature available » Designed for easy field servicing » Setting depths to 9,000 ft (2743 m) *information referenced from supplier catalog.

The WellStar® tubing-retrievable safety valve (TRSV) is a general production, hydraulically operated, downhole TRSV. The rugged hydraulic actuator of the WellStar safety valve provides durability and isolates the internal workings from well fluids through its unique construction. The metal-to-metal (MTM) sealing integrity in the body joints and closure mechanism places it in a premium valve category while featuring an economical price. Proven through years of installations, the simple, compact design enhances the valve’s overall reliability and provides for trouble-free operation. Applications » General production completions Features » Simple, compact design » Complete MTM well containment in the closed position (body/seat connections and flapper) » MTM flapper sealing (no resilient seal required) » Unique hydraulic actuation (single-piece piston/ flow tube) » Hydraulic chamber construction isolates the majority of the internal valve components and exposes them to clean hydraulic fluid » Positive debris barrier at both ends of flow tube in full open position » Maximized piston area and spring force » Flow tube construction prevents well solids and debris from settling on top of the piston *information referenced from supplier catalog.

An annular vent sleeve valve communicates between the casing annulus and producing formation. The valve is a hydraulically operated sliding sleeve device like a surface controlled subsurface safety valve with a hydraulic piston and a power spring to maintain the valve in a normally closed position. The valve is used with a bull plug on top or as an annular safety valve by providing annular bypass while control pressure is applied. With an electrical feedthrough device, this valve functions through a single packer mandrel as an electric power cable passage and annular bypass. On a dual hydraulic packer, the valve operates by a common hydraulic control line that sets the packer and operates the tubing-retrievable safety valve. Hydraulic pressure from the control line shifts the valve open to create a flow path across the packer in the annulus. Spring force closes the valve upon loss of control-line pressure to the piston. If the valve becomes inoperable or closed, an emergency shear feature allows fluid to be pumped into the producing formation from the annulus. Applications » Gas lift and electric submersible pump situations Features » Accurate fluid level shot during pumping because of large ported area through the vent sleeve » Maximum gas vent flow area allows increased gas flow rates and lower circulating pressures » Valve will shut off flow from either direction — production or injection *description excerpted from manufacturers catalogue.
