Abstract
A method for creating a heterogeneous earth model (HEM) of a reservoir field includes generating a group of wellsite models for a group of wellsites of the reservoir field based at least on cluster analysis and cluster tagging performed on log data of the group of wellsites, generating a reference model from the group of wellsite models, where cluster tagging errors of the group of wellsite models is minimized to obtain the reference model, constructing a contour plot of the cluster tagging errors on a cluster by cluster basis in the reservoir field, identifying at least one well location and associated core depth interval based on the contour plot for obtaining additional sampling results, and updating the reference model based on the additional sampling results to create the HEM.
