Abstract

The permeability of porous rock formations is influenced primarily by connected porosity and specific surface area. Elevated porosities typically result in highly permeable rocks, while high specific surface areas lead to low permeability, and this relationship has been described in various forms, such as the well-known Kozeny equation (Kozeny, 1927). Despite the limitations of these relationships (Lukasiewicz and Reed, 1988; Saar and Manga, 1999; Costa, 2006), they often serve as good approximations in sedimentary formations with low clay contents, and their simplicity enables them to be incorporated with ease into numerical models used to describe flow and reaction in porous geological media.
