Dr Ziqiu Xue, Chief Researcher of the CO2 Storage Group at Japan's Research Institute of Innovative Technology for the Earth (RITE) will lead a Global CCS Institute webinar to review and discuss microseismic monitoring at CCS storage sites.
The secure storage of carbon dioxide (CO2) in deep geological formations requires a sufficient overlying cap rock layer to contain the CO2 within the formation. Injection of CO2 increases the formation pressure in the target reservoir. This will decrease the effective pressure and will also lead to geomechanical deformation of the rocks. Therefore, to ensure safety of storage, the CO2 injection must be controlled to maintain integrity of the cap rock.
This webinar will give a simple review on microseismic monitoring results observed at onshore CO2 injection sites such as Weyburn, Canada and Lacq, France. Case study results from the Nagaoka pilot site in Japan will also be introduced, including the field survey results after an earthquake hit the area during CO2 injection.
