Medial axis analysis of void structure in three-dimensional tomographic images of porous media
TL;DR: In this article, the medial axis is constructed during an iterative erosion procedure which replaces the image of the void structure with a smaller version obtained by eroding its surface layer of voxels.

A Functional Relationship Between Capillary Pressure, Saturation, and Interfacial Area as Revealed by a Pore-Scale Network Model
Paul C. Reeves,Michael A. Celia +1 more
TL;DR: In this paper, a network model was developed to test the functional relationship between capillary pressure, saturation, and interfacial area, and the results indicated that a smooth, though complex, functional relationship exists at the continuum scale.

Capillary pressure and hydrophilic porosity in gas diffusion layers for polymer electrolyte fuel cells
TL;DR: Capillary pressure versus saturation curves for drainage of a wetting phase were measured for several gas diffusion layers that are commonly used in polymer electrolyte membrane fuel cells in this paper, and the results were described by several standard capillary models, the parameters of which can be further used to predict the relative permeability of the phases.

The electrical resistivity log as an aid in determining some reservoir characteristics
TL;DR: The usefulness of the electrical resistivity log in determining reservoir characteristics is governed largely by: (1) the accuracy with which the true resistivity of the formation can be determined; (2) the scope of detailed data concerning the relation of resistivity measurements to formation characteristics; (3) the available information concerning the conductivity of connate or formation waters; and (4) the extent of geologic knowledge regarding probable changes in facies within given horizons, both vertically and laterally, particularly in relation to the resultant effect on the electrical properties of the reservoir as mentioned in this paper.

Invasion percolation: a new form of percolation theory
TL;DR: In this paper, a new kind of percolation problem is described which differs from ordinary percolations in that it automatically finds the critical points of the system and is called invasion percolating.

Flow in simulated porous media
TL;DR: In this article, two average statistical properties of the pore space of Fontainebleau sandstones are measured on thin sections and used to generate fictitious porous media which share the same statistical properties as the real ones; the simulation process is thoroughly presented and discussed.
