Abstract:
Coal seams are characterised as highly anisotropic and heterogeneous geological formations with extremely low porosity and permeability at reservoir conditions. Despite the advances in digital rock physics with the introduction of micro-computed tomography (micro-CT) over the last decade, characterising coal remains a challenge. One such challenge is processing micro-CT images to extract fracture features such as aperture, length and orientation which cannot be directly resolved using micro-CT images. We aim to present an automated fracture identification technique using grayscale images obtained from micro-CT imaging of coal.
