摘要：

Injection of supercritical carbon dioxide (CO2) into formations containing carbonate minerals may affect the porosity and permeability of the host rock and overlying caprock due to dissolution of the primary carbonate minerals and possible precipitation of secondary minerals. Simulations of pilot-scale CO2 injection with co-sequestration of sulfur dioxide (SO2) were conducted to assess the competing effects of dolomite dissolution and anhydrite precipitation on formation hydraulic properties. A geochemical model of two promising host formations in the midwestern United States (Rose Run and Copper Ridge) was developed for the purpose of assessing mineral dissolution and precipitation effects on injectivity and containment.
