Induced seismicity potential of CCS

AuthorsVilarrasa, Víctor
Issue Date22-Jul-2019
AbstractThe feasibility of geologic carbon storage as an option to significantly reduce CO2 emissions to the atmosphere has been questioned recently. It has been argued that the overpressure induced by CO2 injection would reactivate faults through which CO2 could migrate upwards, ruining the objective of permanently storing CO2 deep underground. In this presentation, it will be shown that geologic carbon storage can be performed safely, i.e., without inducing seismic events that could reactivate faults and without compromising the caprock sealing capacity. A brief view of the CO2 storage site at Pohang will be also given. Overall, we conclude that a proper site characterization and pressure management are required to achieve a safe CO2 storage.
