Abstract
A method, apparatus, and program product evaluate fracture abundance in a subsurface formation by modeling a fracture network in a three-dimensional volume using geometric primitives. A fracture abundance parameter, e.g., a P32 fracture density, may be determined in part based upon the combined areas of the primitives with cells of a three-dimensional grid.
Claims20
A method of evaluating fracture abundance in a subsurface formation, the method comprising:
- defining a fracture network within a plurality of cells of a three-dimensional model of the subsurface formation using a plurality of geometric primitives;
- determining an area of the plurality of geometric primitives within at least a subset of the plurality of cells by summing areas of individual geometric primitives within each of the subset of cells;
- and
- determining a fracture abundance parameter for the fracture network from the determined area of the plurality of geometric primitives.
