Pore structure of micro- and mesoporous mudrocks based on nitrogen and carbon dioxide sorption
Carbon Capture, Utilization and Storage (CCUS) is one of the solutions to mitigate anthropogenic CO2 emissions. CO2 could be utilized to enhance production of shale gas. By doing so, subsurface storage of CO2 becomes economical. For instance, in the case of Utica formation, economically producible gas-in-place of 104 Trillion cubic feet (Tcf) becomes an incentive to store up to 10 Gigatonnes (Gt) of CO2 (Godec et al. 2014). The storage mechanism of nanoporous shales is highly dependent of its surface properties; 80% of the storage capacity or gas-in-place is estimated to be due to sorption of ...
