Morphology-Based Characterization of 3D Anisotropy in Porous Rock: Pore Orientation
The heterogeneity and randomness of pore structure in rock often hamper the quantitative assessment of pore orientation, which critically determines conduction phenomena. The morphological similarity of pore space in rock is examined by systematic evaluation of phase interception, called mean intercept length (MIL), star length distribution (SLD), and star volume distribution (SVD). The pore space of Berea sandstone is reconstructed by 3D X-ray-computed tomography followed by binarization. The lengths crossed by the evaluation line drawn from randomly selected points within the phase of interests are systematically computed for equally spaced probing direction in 3D space. The gathered values are correspondingly represented by MIL, SLD, and SVD to evaluate the major and minor orientation of pore network. Examples in porous rock and applicability are presented.
