Abstract
X-ray tomography is an accurate and non-invasive technique that measures the internal 3D
structure and composition of materials. To enhance and add predictive power to the collected
data, various analysis techniques have been developed. In this paper, transport properties
calculated directly from the pore space morphology are presented for 36 porous granular
specimens. Results for permeability, conductivity, NMR response and drainage capillary
pressure are shown to be in excellent agreement with experimental measurements over a
wide range of porosities. The results clearly demonstrate the potential of computing a range
of physical properties directly on 3D digitized images generated from X-ray pCT.
