Abstract

In order to predict CO2 storage potential of candidate geological reservoirs, this study investigated the CO2 sorption capacity of sandstone and granite under air-dry and water-saturated conditions using a volumetric technique, at temperatures of 33, 40, and 50 {ring operator}C and pressures up to 20 MPa. The sandstone and granite have the potential to sorb CO2 under the both conditions. A comparison with model predictions (monolayer adsorption, solubility and pore-filling models) indicated that the sorption of CO2 onto rock minerals offers an important mechanism for the CO2-rock interactions which may take place in the course of CO2 injection.
