CHARACTERIZATION, RECONSTRUCTION AND TRANSPORT-PROPERTIES OF VOSGES SANDSTONES

A thorough study of Vosges sandstone samples is presented in this work . First, the geometry of these porous media is analyzed using serial t hin sections. Then, random numerical samples are reconstructed accordi ng to the measured statistical geometrical parameters. Finally, the ma croscopic transport properties are determined from the numerical solut ions in the reconstructed samples of the local equations governing the corresponding transport phenomena and compared to available experimen tal data. Mercury intrusion in the simulated media is modelled and por e size distribution results are compared with those obtained from seri al tomography.
