摘要： A system and method for modeling a subsurface structure. Data representing a configuration of faults, horizons, and/or unconformities may be transformed to a depositional model comprising cells representing an estimated configuration of subsurface structure at a depositional time period when the subsurface structure was formed. Groups of cells in the depositional model may be divided into sub-meshes using iso-surfaces, where one set of iso-surfaces may represent the horizons at the depositional time period. The sub-meshes may be divided into one or more parts using the transformed geological data representing an estimated depositional configuration of the faults. For each group of cells in each sub-mesh part, the group of cells in the sub-mesh part may be represented by a single polyhedron. The polyhedrons may be transformed to generate a current model to represent the current configuration of the faults and horizons using transformed polyhedrons.

摘要： A method of transforming an input stratigraphic grid SGrid which represents a region including one or more geological discontinuities is now disclosed. At least one target cell that is local to one or more geological discontinuities is transformed by displacing at least one target vertex of the target cell of the input SGrid in a selected direction that: i) is selected to approximate a local tangent of the reference horizon; and ii) is oriented from the target vertex to a representative manifold representing one of the geological discontinuities and/or an intersection between two or more of the geological discontinuities. A magnitude of a displacement by which the target vertex is moved is determined according to a non-Euclidian distance between the target vertex of the target cell of the input SGrid and the representative manifold.
