oa A Method for Static-Based Up-Gridding

A method for up-gridding geostatistical reservoir models is proposed. The method generates well-adapted coarse-grid grids for a given realization and target coarse-scale dimensions. While most current grid generation methods are based on either local or global dynamic (flow rate dependent) measures, in this paper, we show that the inclusion of both local and global static information, can greatly improve computational cost while maintaining accurate flow response.
