UPSCALING OF RESERVOIR MODELS BY REUSING FLOW SOLUTIONS FROMGEOLOGIC MODELS

摘要

A method is provided for simulating a physical process such as fluid flow in porous media by performing a fine-grid calculation of the process in a m edium and reusing the fine grid solution in subsequent coarse-grid calculati ons. For fluid flow in subsurface formations, the method may be applied to o ptimize upscaled calculation grids formed from geologic models. The method d ecreases the cost of optimizing a grid to simulate a physical process that i s mathematically described by the diffusion equation.
