Geomechanical integrity verification and mineral trapping quantification for the Ketzin CO2 storage pilot site by coupled numerical simulations

Abstract Long-term integrated site behavior assessment with high spatial resolution on the reservoir scale requires a sophisticated workflow to represent the relevant processes. In our coupling concept we consider the time-dependent occurrence and significance of multi-phase flow, mechanical effects and geochemical reactions. Our numerical simulations for the pilot site Ketzin demonstrate that mechanical reservoir, caprock and fault integrity are maintained during the time of operation and that after 10,000 years CO 2 dissolution is the dominating trapping mechanism and mineralization occurs on the order of 10% to 25% with negligible changes to porosity and permeability.
