A Parallel, Multiscale Approach to Reservoir Modeling

B023 A PARALLEL MULTISCALE APPROACH TO RESERVOIR MODELING Abstract 1 Fine scale heterogeneities may have a significant effect on flow performances in subsurface formations. A large number of grid cells are required to capture the effect of such heterogeneities on flow responses. However flow simulation is rarely feasible without prior upscaling. This presents a problem for the joint integration of fine (well-log) and coarse (seismic production) data. Most approaches proceed in a hierarchical fashion where small scale data is integrated on the fine scale and after upscaling large scale data is integrated on a separate coarse scale. The correspondence between
