Method for determining the permeability of a network of fractures based on a connectivity analysis

摘要

The method involves determining a connectivity index within each of multiple cells depending on number of intersections between fractures by use of a geometrical description. A set of permeability of cells of the fracture network is estimated with the connectivity index above a threshold. A fixed permeability value is assigned within other cells with the connectivity index below the threshold to limit a number of permeability estimations. The development of the reservoir is optimized by simulating fluid flows in the reservoir as a function of permeability of the fracture network of each cell.
