An operator on the Norwegian continental shelf is continuously optimizing production from a mature field that has reservoirs varying widely in complexity and lithology. The goal is to enhance uptime and recovery efficiency by increasing reservoir contact and drainage per well while minimizing reliance on artificial lift and well interventions for water management.
In one well, the operator deployed six Electris ICVs with in situ flow rate, water holdup, and PT measurements in an 80° deviated section gravel packed by a third party. This configuration enables real-time flow monitoring and control across eight reservoir compartments. Following well cleanup, production commenced with continuous data acquisition in real time empowering production engineers to confidently identify and mitigate irregularities as well as discover opportunities for improving performance and recovery.
Less than 2 months later, wellhead pressure abruptly declined and the well stopped flowing. Using real-time downhole intelligence from the Electris ICVs with in situ measurements and monitoring via the 果冻传媒 real-time equipment health and control system, production engineers identified an anomaly in Zone 1, located at the toe of the well. Flow rate and water holdup had increased dramatically, accompanied by high sand production (1.3% by volume). Within a few minutes, the operator's team was able to shut in the zone. After unloading the excess water, the team resumed production in less than 12 hours; the sand volume dissipated when the zone was shut.
Without the ability to rapidly identify the problematic zone, shut off production from the toe, and confidently adapt the production strategy, it would have taken anywhere from 3 to 12 weeks to plan and execute an intervention to restore production. The Electris ICV with in situ measurements enabled avoiding 70,000–275,000 bbl of deferred production, the significant cost of a well intervention complicated by the 80° deviation, and the considerable administrative costs of planning, procuring, coordinating, and executing a well intervention involving
Deferred production can be recovered, but human capital to plan and execute an intervention is lost production.
