Product Sheet Integrity Injection Subsurface Safety Valve
Prevent injection wells from flowing back or blowing out if surface controls malfunction or become damaged.
Injection safety valve
All Integrity valves have only two body joints and use proprietary threads to achieve a reliable, metal-to-metal seal. The innovative and field-proven flapper closure system also features full metal-to-metal sealing and a secondary soft seat; it meets leakage-acceptance criteria substantially more stringent than API and ISO specifications for safety valves.
The modular valve design enables multiple material and design options—including the ability to accommodate a wide range of landing nipple profiles—providing a cost-effective solution for many different applications and operating environments. The orifice can be easily replaced for changing injection flow rates, and Schlumberger offers an optional treatment on selected internal surfaces that minimizes solids buildup, which may be caused by injected fluids. Designs are available for production tubing sizes from 4 1/2 in to 7 in.
