Quantifying Consolidation and Reordering in Natural Granular Media from Computed Tomography Images

Abstract

Packing of granular media is an extremely important determinant in reservoir rock evolution, sound speed propagation, fluid flow and sediment compressibility. X-ray microfocus computed tomography (XMCT) images with high-resolution were evaluated using a grain-based algorithm that quantifies discrete components and bulk properties of sedimentary systems at different states of compaction or at approximately minimum and maximum packing densities. Angularity of these sands ranges from rounded to subrounded to subangular. Network permeability compares reasonably well to measured values; grain aspect ratios and coordination number are reasonable for sands. The grain-based algorithm provides a robust and efficient capability.
