摘要
An upscaling method for efficiently simulating a geological model of subsurface reservoir is disclosed. The method includes providing a fine-scale geological model of a subsurface reservoir associated with a fine-scale grid and a coarse-scale grid. Time-dependent fluid flow solutions, such as fluxes and saturations, are computed for the coarse-scale grid cells. The coarse-scale fluid flow solutions are distributed onto local fine-scale boundaries to obtain local fine-scale boundary conditions. Fine-scale cell fluid flow solutions are computed within the local fine-scale boundaries using the local fine-scale boundary conditions. Two-phase upscaling functions are computed with the fine-scale cell fluid flow solutions and are output to produce a display of fluid flow within the subsurface reservoir.
