Overview

General service, self-equalizing, rod-piston flapper valve

The Recovery™ wireline-retrievable subsurface safety valve is a value-driven, reliable choice. These hydraulically actuated, tubing-pressure sensitive, standard spring valves are suitable for a range of subsurface environments, including both production and injection wells and various wellbore fluids—oil, gas, and water. The rod-piston actuator uses premium dynamic seals and is combined with the rugged flapper-and-seat closure mechanism to provide long-term reliability.

The versatile design is available in a range of sizes and accepts any manufacturer’s lock assembly. The Recovery valve can be used as the primary safety valve by placing it into a hydraulic communication nipple. Alternatively, it can be used as a contingency measure by placing it in a locked-open, tubing-mounted safety valve that is no longer operable.

FAQs

How are the valves qualified?

The valves are validated to API Spec 14A, but their performance exceeds the certification requirements.

Flapper leakage: API Spec 14A allows leakage up to 5 ft3/min. The acceptance criterion for Recovery safety valve flapper systems is 150 times more stringent.

Hydraulic actuator integrity: API Spec 14A allows up to 5% drop in applied hydraulic pressure; for 10,000-psi hydraulic pressure, the acceptable leakage is 500 psi. Recovery safety valve actuators allow <1% drop, as confirmed by rigorous tests.

Slam closure: The valve's flapper system has been successfully slam tested at high flow rates that exceed the Annex K requirements of API Spec 14A.
