Impacts of hydrological heterogeneities on caprock mineral alteration and containment of CO2 in geological storage sites

For long-term geological CO2 storage, heterogeneity of hydrological parameters (i.e., porosity and permeability in this study) leads to the development of heterogeneities in physical parameters within the reservoir that are critical to the risk assessment and monitoring requirements of the project. Caprock heterogeneity is also a critical aspect of CO2 storage planning because of the implications for storage integrity and associated risk...
