... by Andersen et al. (2020 ). Andersen and Zhou (2020) derived an intercept method for multiphase injection, which also extended to low rates. Gas flow in porous media is more complicated than liquid flow due to compressibility and pressure dependent permeability effects. Forchheimer (1901) theory...

... Abstract Rock compressibility is an important physical property of reservoir rocks, which is required for many reservoir engineering and geomechanics calculations. In case of unavailability of lab measurements, empirical correlations are used by the industry. This work is aimed to provide new...

.... The shale is assumed to be compressible and its porosity and pore radius reduce with pressure depletion. The effective pore radius, which also depends on adsorption layer thickness, controls both intrinsic and apparent permeability. This study will address gas production by natural pressure depletion...
