... by incorporating two characteristic parameters: permeability modulus and threshold permeability. These parameters were turned off to compare and validate the obtained solutions with the corresponding conventional analytical solutions. It was found that the earlier models may underestimate the pressure behavior...

... sensitivity. In this paper, the dynamic threshold pressure gradient and permeability modulus are respectively utilized to characterize the low-velocity non-Darcy flow and permeability stress sensitivity. And then the model of volume fracturing well in tight reservoirs simultaneously considering low-velocity...
