RECONSTRUCTED POROUS-MEDIA AND THEIR APPLICATION TO FLUID-FLOW AND SOLUTE TRANSPORT

It is possible to simulate geological media with the same porosity and correlation function of the pore space as real ones. This method is illustrated by two- and three-dimensional examples and discussed. Then, programs able to solve the local field equations in any geometry are used to study various transport processes such as convection, diffusion and Taylor dispersion in these media whereby macroscopic quantities such as permeability, formation factor and dispersion tensor are obtained; the first two quantities are compared to experimental data in Fontainebleau sandstones.
