Manage production or injection flow in multizone intelligent completions

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.

Our extensive track record in intelligent completions gives us the expertise in downhole flow control technology—including its applications, challenges, and solutions—to deliver a highly reliable and robust flow control portfolio.
