Abstract

In this work we present the analytical solution for the problem of oil displacement by a hot fluid containing a solvent as a combined thermal-solvent method of enhanced oil recovery (EOR). We consider one-dimensional two-phase three-component (oil, solvent, and water) flow in a homogeneous and isotropic porous media. Other hypotheses of the model are incompressible system with no diffusion and no chemical reactions; gravity and capillary effects are neglected. Following Amagat’s law, total volume is conserved and Henry’s law is used to relate the solvent concentrations. The heat capacities of the components and the rock were considered constant. The dependent variables of the problem are oil saturation, solvent concentration in the oil phase, and temperature. The solution, composed of shock and rarefaction waves and constant states, was obtained using the method of characteristics and analyzed for different initial and injection conditions.
