WebABSTRACT Tight porous media have extremely low porosities and permeabilities, which can induce low-fluid mobility and a significant non-Darcy flow phenomenon. We build a unified mathematical model considering the non-Darcy seepage and the viscoelasticity mechanism, which includes two new parameters related to the non-Darcy flow mechanism.
