How it improves performance

Microseismic monitoring is a critical tool for operations requiring massive fluid injections, such as CCS, UGS, saltwater disposal, stimulation, and geothermal injection, which can lead to induced seismic events. Real-Time Induced Seismicity Monitoring (RT-ISM) is the first automated microseismic monitoring system that detects these seismic events, providing real-time information on the magnitude and location of the event from continuous fiber-optic distributed acoustic sensing (DAS) acquisition.

By continuously monitoring microtremors in the surrounding caprock, users can understand how the reservoir is responding to operations and adjust stimulation or injection activities to ensure compliance with regulatory thresholds. For advanced interpretation, a dedicated SLB team can manually process data from the system to help integrate seismological, geophysical, and geological components. RT-ISM is conveyance agnostic and can be deployed with both permanent and temporary fiber installations.

How it works

The RT-ISM solution acquires continuous DAS data through an optical interrogator. It leverages edge computing to perform all required processing and computations on site. The setup is lean, with an extremely compact footprint, and includes features that enable a minimum data stream transmission if remote processing, remote viewing, or both are required. Once installed, the microseismic monitoring solution requires no human interaction in situ.
