Schlumberger has introduced Symphony* live downhole reservoir testing, a technology platform that enables operational control of the downhole testing toolstring to deliver real-time downhole measurements. Symphony testing reduces operational time and improves safety and efficiency while enabling informed decision making for better reservoir understanding and reduced field development planning uncertainty.

Symphony testing unites Muzic* wireless telemetry with the downhole string, creating a digital solution that enables real-time control of the dynamic range of conditions during well testing operations. The digitally enabled toolstring is customized for the test objectives to position, isolate, connect, measure, control, sample, select and profile the reservoir with real-time verification.

“Symphony testing’s digital enablement significantly increases operational control to acquire actionable data in real time, saving our customers operational time and achieving well test objectives more efficiently,” said Aparna Raman, president, Reservoir Performance, Schlumberger. “Our Symphony testing platform is supported by our Performance Live* digitally connected service that leverages domain expertise, cloud-based applications and automated data workflows to enable faster, more informed decision making.”

Extensive qualification of Symphony testing has been conducted offshore Asia, the Middle East and the North Sea. In offshore Asia, Symphony testing delivered perforating and well testing services in a challenging shallow reservoir. Using wireless control, Symphony testing eliminated the potential pumpout of a conventional drillstem testing (DST) toolstring that operates with pressure pulses. By quickly modifying test sequences guided by real-time data, Symphony testing helped avoid sand production while maintaining a single run, saving the operator 24 rig hours.
