A Study on the Suppression of Leakage of CO2 Purposefully Stored in the Sub-sea Geological Formation
- Professor Toru Sato
For the realization of Carbon dioxide Capture and Storage (CCS), consideration of the risk of CO2 leakage from the CO2 reservoir in the sub-sea geological formation. If unexpected CO2 leakage takes place and some of the sensors installed on the seafloor detect it, the leak information such as leakage position and leakage flux must be identified as soon as possible. Therefore, we are developing a stochastic inverse analysis model that estimates the CO2 leakage position and leakage flux from limited number of fixed-point observation information.
