Continuous, real-time sandface measurements

WellWatcher Flux multizonal reservoir monitoring system successfully addresses the challenge of acquiring reservoir data in real time across the sandface of wells with multistage completions. Flow profiles can be monitored and characterized without having to perform interventions or choke back production.

A single wellhead penetration enables multidropping of conventional quartz pressure and temperature gauges, as well as arrays of miniaturized digital temperature sensors distributed along both the sandface and the upper completion. Each array can comprise up to 60 sensors. These sensors provide the highest-resolution temperature measurements in the industry. An inductive coupler fully integrated into the completion hardware enables wireless communication and power transmission between the upper and lower completions.

Complex completions installed in two parts consist of a lower completion containing the gravel-pack assembly across the production zone and an upper completion containing the packer and production tubing. Connecting electric downhole cables between the two zones is usually highly problematic and therefore traditionally, sensors have not been deployed across the reservoir interval of the lower completion. The inductive coupler eliminates these restrictions. High tolerance for debris and vibration makes the system particularly suitable for multistage deepwater completions, where intervention costs and risks are high.

Actionable information in real time for production optimization

The WellWatcher Flux system has been used to monitor cleanup-phase effectiveness, track injection flow paths, identify the most prolific producing zones, identify water or gas breakthrough, and monitor changes. The surface acquisition system can transmit data to your office, where real-time analysis with thermal modeling software allows flow events to be interpreted even in high-angle wellbores, enabling fast, informed decisions for optimal control of assets.
