In this paper, we propose a local-global multiscale mortar mixed finiteelement method (MMMFEM) for multiphase transport in heterogeneous media. Weconsider the two-phase flow system, the pressure equation is solved via themultiscale mortar mixed finite element method, a mass conservation velocityfield can be obtained, then we use explicit finite volume method to solve thesaturation equation. We use polynomials and multiscale basis to form the coarsemortar space. The multiscale basis is the restriction of global pressure fieldobtained at previous time step on the coarse interface. We solve the pressureequation on the fine grid to initialize the simulation. Numerical experimentson some benchmark 2D and 3D heterogeneous models are provided to validate theperformance of our method.
