New equations for estimating the relative permeability curves for both water-oil and gas-oil systems have been developed for shaly sands in mixed wettability formations of the Western Desert in Egypt.

The Palmer-Mansoori (P-M) theory of permeability changes incorporated into a pseudosteady-state equation can predict the approximate peak gas flow rate and decline with depletion for coalbed methane ...

Predictions from two previously published models and a new model for the relative change in cuticular permeability with boiling point, octanol/air partition coefficient, and/or molar volume of a wide ...
