Simulation of Gravitational Instability and Thermo‐Solutal Convection During the Dissolution of CO in Deep Storage Reservoirs

The temperature of deep hydrothermal sedimentary reservoirs varies between 50 and 250 °C, while the temperature of injected CO can be much below the reservoir temperature. Most past studies did not consider temperature effect on the CO dissolution trapping in storage reservoirs. We have performed numerical simulations of coupled multiphase flow, solute, and heat transport for liquid/supercritical CO injection in a storage reservoir for different...
