Abstract
To provide a simplified subterranean model of a subterranean structure, a first grid size for the simplified subterranean model is selected, where the first grid size is coarser than a second grid size associated with a detailed subterranean model. The simplified subterranean model is populated with subterranean properties according to the selected first grid size, where multiple realizations of the simplified subterranean model are provided for different sets of values of the subterranean properties. The realizations of the simplified subterranean model are ranked based on comparing outputs of simulations of the realizations with measured data associated with the subterranean structure.
