The goal of carbon capture and geological storage (CSS) is to reduce carbon dioxide (CO2) release to the atmosphere by capturing CO2 from powerplants and industrial facilities and subsequently injecting it into a deep permeable geological formation for long-term storage. Successful and safe CCS operations require developing and improving subsurface monitoring technologies for tracking CO2 movement, evaluating storage integrity and early detection of CO2 leak from storage. In this study, we present a novel, fully-integrated Electromagnetic (EM) and seismic acquisition system designed to efficiently detect the boundaries of an injected CO2 plume and monitor its evolution at several stages of injection at a field site. For both methods, we present the preliminary inversion results that will be used as baseline models for future time-lapse crosswell imaging experiments.
