Pore scale modeling plays a key role in fluid flow through porous media and associated macroscale constitutive relationships. The polyhedral shape and effective local pore size within granular material microstructure are computed in this study by means of the Euclidean Distance Transform (EDT), a local maxima search (non-maximum suppression), and a segmentation process. Various synthetic packed...

Inclusion-based formulations allow an explicit description of pore geometry by viewing porous rocks as a solid matrix with embedded inclusions representing individual pores. The assumption commonly used in these formulations that there is no fluid pressure communication between pores is reasonable for liquid-filled rocks measured at high frequencies; however, complete fluid pressure communicati...

Capillary pressure (Pc) curves acquired using the Magnetic Resonance Imaging (MRI) technique, call GIT-CAP, have 70-100 data points. This extra data, when compared with traditional porous plate or centrifuge techniques, allows for the interpretation of more information from the Pc curve. In particular, the pore throat size and relative permeability can be extracted. The pore throat size can be ...

Compacted clays are considered as excellent candidates for barriers to radionuclide transport in future repositories for nuclear waste due to their very low hydraulic permeability. Diffusion is the dominant transport mechanism, controlled by a nano-scale pore system. Assessment of the clays' long-term containment function requires adequate modelling of such pore systems and their evolution. Exi...

Carbonate rocks have a wide variety of pore shapes and different types grains, which greatly affect the elastic properties characteristics reservoir. This causes certain difficulties in petroelastic modeling. One problems is scale input data, then used to build rock physics model. The paper presents results studying three core samples carbonate Upper Devonian Lower Carboniferous age, are locate...

Abstract SiC foam ceramics are extensively used in numerous industrial applications that require high-temperature conditions. They can be as thermal insulation, structural catalyst supports and energy storage materials. In this article, effective conductivity of at high temperature is studied by steady plane heat source method. This research aims to investigate the variations with pore density,...
