Characterisation of clastic depositional environments and rock pore structures using the Carman-Kozeny equation: Australian sedimentary basins

The Carman-Kozeny formulation is used to generalize concepts for classifying clastic depositional environments for Australian formations, and to explore rock types and their diagenetic features. The interest is not so much to derive single hydraulic unit relationships for specific geological zones, but to introduce a model for the purpose of classifying the characteristics of geologic depositional environments and associated pore structures. The paper demonstrates how this approach may be used for data validation and integration, and in applications of “reverse modelling”, allowing estimation of pore structure parameters, porosity and permeability, for a particular geological situation.
