DOWNLOAD POSTER PDFDuring the miscible displacement process, a solvent fluid is injected into a porous medium; it mixes with a resident fluid. The fluid mixture moves in the porous medium as a single phase flow, with a velocity that follows Darcy's law. Furthermore, the solvent concentration satisfies a convection-dominated parabolic problem, with a diffusion-dispersion tensor that depends on the fluid velocity in a nonlinear fashion. The fluid pressure equation is coupled with the concentration equation. These essential aspects constitute the miscible displacement problem. This problem arises in many applications, such as production of trapped oil in reservoirs by enhanced oil recovery. The poster will present numerical simulations of miscible displacement by using discontinuous Galerkin method. The high order numerical discretization maintains mass conservation and demonstrates low sensitivity to grid distortions. The numerical method is implemented on the parallel architecture using overlapping domain decomposition. Simulation results show the robustness of the method, as well as efficiency on a parallel cluster.
