Fracture network mapping and estimation of its permeability constitute two major steps in static model preparation of naturally fractured reservoirs. Although several different analytical methods were proposed in the past for calculating fracture network permeability (FNP), different approaches are still needed for practical use. We propose a new and practical approach to estimate FNP using statistical and fractal characteristics of fracture networks. We also provide a detailed sensitivity analysis to determine the relative importance of fracture network parameters on the FNP in comparison to single fracture conductivity using experimental design approach.
