Accurate estimation of transport properties from microtomographic images

Abstract

Estimating and minimizing several sources of numerical error result in very accurate predictions of transport properties directly from digitized images. Simulation of electrical conductivity on microtomographic images of Fontainebleau sandstone are in excellent agreement with experimental measurements over a wide range of porosity. The results show the feasibility of combining digitized images with transport calculations to accurately predict petrophysical properties of individual rock morphologies.
