Abstract: A method includes assembling a model including a plurality of independent objects. The independent objects include surfaces, properties, and zones. The method also includes decomposing the model into vertical columns, tiles, or both. The method also includes discretizing an incoming request into the vertical columns, the tiles, or both. In response to the discretized request, the method also includes performing a vertical pin analysis on the model to retrieve a portion of the surfaces, a portion of the properties, or both that are geo-located in the vertical columns, the tiles, or both. The method also includes modelling the retrieved portions to generate an output. The method also includes comparing the output with subsurface data. The method also includes modifying the model based at least partially upon the comparison.

Abstract: Precise boundary segment intersection methods and systems for boundary representation are described. For example, in one embodiment, a method includes computing a plurality of intersections of a plurality of segments, computing an uncertainty associated with each intersection of the plurality of intersections, and determining whether to aggregate at least one of the plurality of intersections with another of the plurality of intersections based on one or more of the determined uncertainties. In another embodiment, the method may further include determining whether to consolidate at least one non-aggregated intersection with at least one other intersection based on a topological consistency requirement.
