Pore Space Characterisation and Permeability Prediction Using Fast Network Extraction and Pore Throat Conductance Calculation (SPE-113511)

摘要

State of the art X-ray micro-computed tomography (micro-CT) of reservoir rock samples and cuttings allows reconstruction of the pore network with micrometric spatial resolution that is suitable for further petrophysical and fluid flow properties evaluation. Synchrotron tomographic beam lines, compared to conventional micro-CT systems, allow better 3D representation of the pore space. The digital rock volume is used for medial axis extraction and for 3D pore space morphological characterization (i.e. connectivity, pore-body/throat size, shape factors, etc.).
