... assumption). Applying this method and an experimental 3D imaging of flow paths to different types of vuggy carbonate samples have indicated that fluid flows through vuggy carbonates are generally characterized by formation of preferential flow paths (i.e., channeling flow), where considerable amounts...

... Abstract The present study investigates fluid flows and permeabilities through vuggy carbonates via a single-phase fluid-flow experiment and a numerical model simulation using X-ray CT. 3D imaging of flow paths in vuggy carbonate samples reveals that fluid flows through vuggy carbonates...

... Abstract In a fractured reservoir, three dimensional (3-D) preferential flow paths are likely to be formed (i.e. 3-D channeling flow) due to the heterogeneous aperture distributions of individual fractures. However, to date there is no practical modeling method that precisely maps the 3-D...

... ABSTRACT In order to investigate the effects of viscous ratio (water/oil) and the connectivity of flow paths in fracture network on oil recovery from a single fracture, two kinds of water flooding simulations using lattice Boltzmann method have been conducted to single fracture models...
