In this work we look for analytical solutions for the injection of a supercritical fluid mixture of carbon dioxide and water into porous rock filled with water. After injection of the water/CO2 mixture a complex interaction between physical transport and the phase redistribution of the components, i.e., water and CO2, occurs. This redistribution is usually described in terms of local thermodynamic equilibrium. We take into account the heat effects related to the cold fluid injection and to the dissolution of CO2.
