Abstract
A method, system and machine-readable medium encoded with machine-executable instructions for creating an ensemble of estimated upscaled reservoir models from fine-scale geological models of the subsurface region to produce coarse-scale models of the subsurface region, the method includes computing coarse-scale attributes for a plurality of realizations, numerically simulating coarse-scale properties for a subset of the plurality of realizations, generating calibration data based on the numerically simulated coarse-scale properties and corresponding coarse-scale attributes, and estimating coarse-scale properties for a plurality of realizations, wherein the estimating is done using a statistical procedure and is calibrated using the calibration data to produce coarse-scale properties of an ensemble of upscaled models.
