Manara electric ICVs in multizone wells

Monitor and control flow separately from each producing zone

3 horizontal multizone wells depicted by blue lines, with zones shown by clusters of white cubes.

Control each zone separately, and produce separately or commingled

Field-proven Manara™ first-generation electric interval control valves (ICVs) are equipped with in situ sensors and improve recovery by enabling real-time monitoring and control of each zone of your well without intervention.

Whether you commingle the produced fluids or keep them separate with a dual-tubing completion, Manara ICVs help you gain deeper understanding of your reservoir, enabling real-time flow control changes to maximize recovery for each zone—even if pressures and fluid properties are significantly different.

Manage reservoir changes without intervention

The system intelligence continues to measure flow and recommend choke settings to maintain optimal performance over time with dynamic changes in the reservoir behavior—all in real time, without any interventions such as production logging. The real-time flow data also help you manage artificial lift (e.g., gas lift) to optimize recovery.

Manara electric ICVs simplify your completion by eliminating the many control lines required in conventional hydraulically operated systems. That leaves more room in the wellbore for fullbore commingled production or dual-tubing completions that ensure compliance with zonal allocation reporting.

The technology makes it easy to delay water or gas breakthrough near the heel—common in longer multizone wells—and thereby maintain or even improve production from the deeper zones you invested time and money to reach. The overall effect is improved recovery across the whole well, with real-time control of each zone.
