Microseismic Monitoring of CO2 Storage
Proceedings, 2012 Geomechanical deformation, if it creates and/or reactivates faults and fractures, can provide a leakage pathway for CO2 to escape the reservoir. By monitoring microseismicity in and around the reservoir, the risks of leakage can be assessed. Although it is a mature technology for monitoring hydraulic fracturing in tight gas reservoirs, microseismic ...
