Robust Coarse Scale Modeling of Flow and Transport in Heterogeneous Reservoirs

A014 ROBUST COARSE SCALE MODELING OF FLOW AND TRANSPORT IN HETEROGENEOUS RESERVOIRS Abstract 1 Techniques for the generation of accurate coarse scale simulation models are described and applied. An iterative procedure for the calculation of upscaled transmissibilities referred to as an adaptive localglobal method is presented. This approach uses a global coarse scale flow solution for the determination of the local boundary conditions required for the upscaling computations. Enhanced accuracy relative to existing techniques is demonstrated. For transport calculations the method is applied in the context of multiscale modeling (which entails a reconstruction of the fine scale velocity field followed
