Case Study Eni Overcomes Gas Field Development and Production Challenges with Standard Configurable Flow Control Valves
Expedited delivery of multiposition interval control valves enables revised deepwater completion design.
Surface-actuated downhole flow control valves for selective control of production or injection
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.
