... ‘transient flow’) and is very well understood (at least at the producing well’s location). The capillary shockwave represents a moving boundary to the pressure decay field that forms around the well ( Hurst 1934 ). This active region of decay behind the moving shock front will adopt a near semi-steady state...

... first is the analytical Oda method which defines the DFN permeability based on fracture geometry ( Snow, 1969 ; Oda, 1985 ). While in the second approach, DFN permeability is calculated numerically by imposing a pressure boundary on the faces of any grid cell. Then the flow rate and the corrsoponding...
