Interactions between CO2 and H2O fluids and the rocks that host them are of significance for Geological Carbon Storage (GCS) for several reasons. These interactions determine the amount of CO2 that can be trapped in solution and in minerals. The petrophysical properties of reservoir and cap rocks, especially porosity and permeability, are also affected. Carbon storage in fluids and minerals, coupled with potential changes to the petrophysical properties of rocks, have a direct bearing on the long-term effectiveness of GCS.

Many potential reservoir rocks contain a range of minerals that may react at very different rates....
