HOUSTON –Schlumberger has released its Quartet downhole reservoir testing system enabled by Muzic wireless telemetry, which provides data in real time so that customers can manage wellbore events and refine well tests, ensure their objectives are met, and gain a better understanding of the reservoir.

The Quartet system uses wireless bidirectional communication to provide downhole tool status, and pressure and temperature data, which allows test design modifications and validation of test data while reservoir testing is taking place, said Schlumberger. The system also enhances testing efficiency by making possible the isolation, control, measurement, and sampling of the reservoir in a single run.

Field tests using the Quartet system with wireless telemetry have run in Egypt, Indonesia, Qatar, Brazil, and Angola in environments ranging from onshore to deepwater.

In Brazil, equipment and Schlumberger used the Quartet system on a well in the presalt Santos basin to monitor operations and adjust the test program in real time. The visualization of downhole data during flow and buildup periods facilitated real-time interpretation of well test data, leading to all test objectives being achieved, and saving Petrobras costly deepwater rig time, said Schlumberger.
