Carbon dioxide sequestration in deep saline aquifers is being considered as one of the more important geological sequestration types due to the potentially large storage capacity when compared to some other geological sequestration reservoirs. CO2 will react with formation rock when injected in dolomite formations, due to the rock dissolution and precipitation of reaction products permeability may be changed. Several parameters affect these interactions including pressure, temperature, brine composition, CO2 injection rate, and overall injection scheme.
