We propose a novel workflow to investigate the complex flow behaviors and remaining oil distribution related to the oil?gas?water three-phase system based on information from typical outcrops of fractured-vuggy reservoirs. A refined geological model is b...

Digital rock physics (DRP) has been widely used as an effective approach for estimating the permeability of porous media. However, conventional implementation of DRP requires the reconstruction of three-dimensional (3D) pore networks, which suffer from i...
