In recent years many research results, both theoretical and experimental, have been published to improve the accuracy of dual porosity modeling. Most of these studies dealt with the accuracy of matrix-fracture transfer flow (MFTF) calculations (so-called transfer functions). Some studies concentrated on creating empirical transfer functions through single matrix block modeling, while others incorporated MFTF calculations in dual porosity model by using some type of sub-gridding or averaging technique. However, flow in fractures and its effects on MFTF have not been fully studied in the literature.
