Simulation of multi-phase flow in porous media has wide applications, which include in particular the management of existing petroleum fields and the development of new oil and gas reservoirs. In this talk the speaker will introduce a new efficient IMPES scheme for the simulation of incompressible and immiscible two-phase flow in heterogeneous porous media with capillary pressure. The new algorithm is locally mass conservative for both phases. Moreover, the new scheme is unbiased with regard to the two phases and the saturations of both phases are bounds-preserving if the time step size is smaller than a certain value. They will also introduce an efficient energy stable numerical method for the Maxwell-Stefan-Darcy two-phase flow model in porous media, which can preserve multiple important physical properties of the model. Some interesting examples will be shown to demonstrate the efficiency of the new numerical methods.
