Towards precise prediction of transport properties from synthetic computer tomography of reconstructed porous media

Transport properties of a multiscale carbonate rock are predicted from pore scale models, reconstructed using a continuum geometrical modeling technique. The method combines crystallite information from two-dimensional high-resolution images with sedimentary correlations from a three-dimensional low-resolution microcomputed tomography (mu-CT) image to produce a rock sample with calibrated porosity, structural correlation, and transport properties at arbitrary resolutions. Synthetic mu-CT images of the reconstructed model match well with experimental mu-CT images at different resolutions, making it possible to predict physical transport parameters at higher resolutions.
