Recover more oil from multilateral wells with a smarter completion

Proven in challenging environments since 2014, Manara production and reservoir management system improves recovery with real-time monitoring and control of multiple zones in each lateral of your multilateral well—without intervention and without time-consuming complications during installation.

The result is unprecedented levels of in-lateral zonal control and monitoring, all in real time, to maximize hydrocarbon sweep and recovery.

Save time and money on production optimization

Unhindered by wellhead and packer restrictions that limit the number of flow control valves (FCVs) and downhole gauges in a conventional completion, the Manara system enables delivers real-time, continuous measurements and infinite control of multiple compartments or zones in each lateral.

The downhole intelligence and control capabilities are combined with surface intelligence to deliver

  • water cut measurements at the sandface ensuring efficient well cleanup
  • dial-a-rate capability in each zone to ensure optimal reservoir drainage
  • 24/7 real-time production logging to highlight unforeseen production changes.

Reservoir and production management decisions that took months—even years—are now possible in days or minutes. Continuous feedback and digital control enables optimized production and maximum recovery.

Interventionless control of water cut and fluid flow rate by zone—even in long laterals

As the well produces, the intelligence continues to improve performance by measuring flow and manipulating chokes to maintain optimal performance over time with dynamic changes in the reservoir behavior—all in real time, without intervention.

That means, for example, that instead of shutting off a whole lateral because of water or gas breakthrough, it’s possible to identify the problem zone, choke it back, and continue to produce from the deeper zones you invested time and money to reach. The optimization workflow monitors flow rates, water cut, pressure, and temperature at the sandface to optimize all of the FCVs without the “experimentation” required in less sophisticated systems. The overall effect is improved recovery across all of your laterals—and less complication for reservoir and production engineers.

Simplified installation improves reliability and flexibility

A single electric control line connects each station to the next and the entire system to the surface, minimizing connection points and splices, simplifying installation, and increasing reliability. Intellitite downhole dual-seal dry-mate connectors eliminate potential leak paths, a common issue with monitoring systems. Power and data are transmitted wirelessly across junctions via inductive couplers.

The inductive coupler connects the lower and upper completion, simplifying installation and subsequent interventions if required. Eliminating the control line across the junction enables the lower completion to be run in on drillpipe. The pipe can be pushed, pulled, and rotated to overcome friction and reach target depth in extended-reach wells without fear of damaging control lines, removing any restrictions on the length of the wellbore. Subsequently, the upper completion is installed, and the coupler establishes electrical connection between the two.
