Abstract

We used numerical simulation experiments to understand a potential CO 2 injection site, the Arbuckle formation under the Thrall-Aagard reservoir in Kansas. Including the potential CO2 plume migration, convective mixing, and drying-out processes, we investigated thermophysical processes associated with CO2 injection, namely, Joule-Thompson cooling and enthalpy changes associated water vaporization and CO2 dissolution. Results suggest that the rate of pressure dissipation after stopping injection was rapid in the Arbuckle formation since this formation is hydrologically connected to open surface, the Ozark Plateau aquifer system in Missouri. Consequently, CO2 densities radically drop with pressure dissipation. In addition, as supercriticalphase CO2 comes into contact with formation brine, CO2 will dissolve into this fluid, an exothermic reaction at typical in situ conditions appropriate for CO2 sequestration. Thus, CO2 dissolution potentially increases both the enthalpy and temperature of CO2-laden brine. However, the magnitude of this increase was minor in most cases (less than 1°C). In summary, the detailed understanding of thermophysical properties of CO2 is necessary prior to field-scale deployment in this site.
