Practical Approaches for the Scale Up of Flow in Heterogeneous Porous Media

2:00 PM-4:00 PM
Room: Ballroom C

Reservoir characterization procedures routinely generate highly heterogeneous, finely gridded geologic descriptions. These detailed models must be coarsened, in some way, for purposes of reservoir simulation. Though many theoretical results exist for such problems (e.g., homogenization results), most of the practical approaches used in industry are at best only loosely based on theoretical findings. The purpose of this minisymposium is to discuss both the underlying theory and the actual implementation of various techniques used in practice for the upscaling problem. Our hope is that the combined discussion of both theory and practice will spur some new interactions.
