TY  - JOUR
AB  - Given the high level of detail present in numerical models, fluid dynamic simulations of subsurface flow in porous media are very intensive in computational time. Moreover, to account for the inherent uncertainty in the information available, many realizations of the same model should be constructed to extract statistical data. For this purpose, less detailed coarse scale models are often constructed, starting from the fine scale ones but with a reduced number of grid cells. Each grid cell is now bigger in physical terms and must contain information relative to the entire portion of rock contained in it. The challenge in this process is to find equivalent properties for the important variables in the system, ensuring that the original knowledge about the geological reservoir is preserved as much as possible. Upscaling is the procedure with which these coarse scale effective properties are obtained. We present an upscaling method for the saturation equation governing advcction of a passive tracer in a porous medium. The upscaling rule is such that the saturation on the coarse scale closely matches the averaged fine scale saturation. Results are presented in one-dimensional systems and compared to analytical solutions.
