Abstract

Results from a numerical study examining the cross-property correlations linking fluid permeability to conductive properties and to a number of pore size parameters based on 3D digitized images of sedimentary rock are presented. In particular we focus on correlations based on the pore volume-to-surface-area ratio (Vp/S), a critical channel diameter lc associated with mercury porosimetry measurements, length scales associated with the NMR relaxation time T2, as well as mean survival time . Differences between the length scales are discussed. All correlations give good agreement but permeability estimates based on the critical diameter lc are found to be most reliable.
