The Drill Stem Test (DST) plays a pivotal role in prospect evaluation and subsequent field development planning. Therefore, it is imperative to acquire reliable, high-accuracy downhole pressure and temperature data in a timely manner to allow the reservoir evaluation to be conducted without introducing additional uncertainty or delay.

Acoustic Data’s SonicGauge™ Wireless Monitoring System delivers surface-read-out (SRO) of downhole pressure and temperature data in real-time via acoustic telemetry transmitted through the tubing. Access to real-time reservoir response data allows live analysis of the well test, leading to fast and informed decision-making at wellsite or remotely via satellite or cellular communication. In turn, this decreases risk, rig time and lost production. Multiple SonicGauge wireless downhole gauges can be deployed along the test string to capture high accuracy, flowing and shut-in pressure and gradient data.
