(147c) Chemical Impacts of CO2 Intrusion into Heterogeneous Caprock
Heterogeneities in permeability and porosity could significantly affect containment of intruded CO2 within the caprock. Key results of analysis include forecasted spatial and temporal CO2 distribution in caprock near injection wells, because the pressure and CO2 saturation tend to be the highest over the reservoir. The risk of CO2 leakage through the caprock is evaluated, and mineral alteration of the caprock and self-sealing effects are assessed.
