CO2 migration and distribution in multiscale-heterogeneous deep saline aquifers

Large volumes of carbon dioxide (CO2 ) captured from carbon emission source can be stored in deep saline aquifers as a mean of mitigating climate change. The deep saline aquifers are naturally heterogeneous at multiple scales. It is important to generate representative multiscale heterogeneous ﬁelds...
