System and method for representing and processing and modeling subterranean surfaces
First Claim
1. A method for processing data used for hydrocarbon extraction from the earth comprising the steps of:
- receiving sampled data representing earth structures;
identifying one or more symmetry transformation groups from the sampled data;
identifying a set of critical points from the sampled data;
generating a plurality of subdivisions of shapes the subdivisions together representing the earth structures, the generation being based at least in part on the set of identified critical points and the symmetry transformation groups; and
processing earth model data using the generated subdivision of shapes.

Abstract
Methods and systems are disclosed for processing data used for hydrocarbon extraction from the earth. Symmetry transformation groups are identified from sampled earth structure data. A set of critical points is identified from the sampled data. Using the symmetry groups and the critical points, a plurality of subdivisions of shapes is generated, which together represent the original earth structures. The symmetry groups correspond to a plurality of shape families, each of which includes a set of predicted critical points. The subdivisions are preferably generated such that a shape family is selected according to a best fit between the critical points from the sampled data and the predicted critical points of the selected shape family.
