Real-Time Data Simulator for the Qualification of DAS Passive Seismic Geothermal Monitoring Systems

November 2, 2023


The use of the Distributed Acoustic Sensing (DAS) technology is gaining traction as the scientific community values its versatility while benefiting ease of deployment. This technology has been applied in a wide range of geophysical applications.  The distributed nature of the sensing coupled to the large aperture array enabled by long cable(s) provides robust passive seismic monitoring systems. We developed a simulator of DAS-acquired passive seismic data for Geothermal injection monitoring, which outputs data at real-time speed. The simulator serves for the verification of the acquisition geometry and the processing system when monitoring hydraulically-induced fracture network.
