Robust and Cost-Effective Monitoring of Induced Seismicity in CCS

Summary We present results and lessons learned from microseismic monitoring at megaton-scale CCS sites. The data examples allow the comparison of different network configurations and sensor technologies including surface, downhole, and DAS. Comparison of different sites reveals what information is most important to resolve, and at what scale, in order to be of value for storage operations. We can derive some basic criteria for network design aiming at obtaining this information in the most robust and cost-effective way.
