Downhole Interval Control Valves (ICVs)

Surface-actuated downhole flow control valves for selective control of multiple production or injection zones

Interval or flow control valves can be operated automatically, manually, or remotely as part of an intelligent completion. Used to control multiple zones selectively, they reduce water cut and gas cut, minimize well interventions, and maximize well productivity. 

Schlumberger provides on/off and multiposition, annular and inline flow control valves for both producer and injector applications. Valves are available in a range of sizes (2 7/8 in, 3 1/2-in slim, 3 1/2 in, 4 1/2 in, and 5 1/2 in) and metallurgies to suit your reservoir parameters.
