... Abstract Formation evaluation including porosity and directional permeability assessment in complex carbonate formations is challenging due to the anisotropic and heterogeneous nature of the formation. The pore structure can be captured by digital rock technology, which makes the constriction...

..., relative permeability model and the coal matrix porosity models, as illustrated in Fig. 2 . The sorption-induced strain and mechanical strain may open or close the coal cleats which contribute to the permeability modification. With the modulus reduction ratio, the directional permeability could...
