On the connection between morphological and stochastic permeability models of porous media
Abstract
We present a theoretical framework that connects morphological and stochastic models of the fluid permeability in porous media. Morphological models relate fluid permeability to properties of the pore space geometry, such as the porosity and specific interfacial area. On the other hand, stochastic theories of flow and transport are based on statistical representations of the fluid permeability obtained from the analysis of permeability data, which do not make a direct connection with the pore morphology. Using the local porosity theory, we develop a link between the morphological and stochastic permeability models, and we show how statistical properties follow from the small-scale variability of the morphology.
