1. A method for forming a geologic model of a subsurface region comprising: obtaining data related to the subsurface region; constructing a framework to represent the subsurface region; selecting a template from a plurality of templates, wherein the selected template provides at least one property that is characteristic of the subsurface region, wherein the selected template is a quantitative and hierarchical characterization of at least one template region for a specific geologic setting and the template region is a volumetric region within the geologic model, bounded by explicit interfaces and having a geologic character represented by the selected template; inserting the selected template into the framework; selecting a template hierarchical level for the selected template; creating at least one conceptual interface within the template region based upon the selected hierarchical level and geologic characteristics associated with the template, wherein the at least one conceptual interface has at least one interface property associated therewith; defining at least one texture region within the template region using at least one of the explicit interfaces and the at least one conceptual interface; modeling at least one texture property within the at least one texture region to form the geologic model; and outputting the geologic model.
