| Abstract | In this proposal the mixed multi-scale finite element (MMSFE), [1, 4, 5, 10], and multiscale finite volume (MFVM), [15], methods are combined in an arbitrary order mimetic least-squares discretization, [6, 8, 17, 18, 19] to solve ow problems in reservoir engineering. Mimetic methods satisfy conservation laws at the cochain level, without any reference to basis functions. The anisotropic, heterogeneous, material-dependent constitutive laws are satisfied in a point-wise sense. In this respect, mimetic methods resemble finite volume methods for the topological relations and finite element methods for the metric-dependent relations. The topological relations are additive, so properties at the fine scale can be immediately transferred to the large scale by summation. The large scale heterogeneous properties are directly obtained from the small scale dynamics in the mimetic spectral least-squares formulation, yielding a systematic procedure for coarsening (upscaling) and refinement. The ultimate goal of this study is to produce an effective coarse grid model for the flow in porous media on rough grids. |
