Liquid-Gas Relative Permeabilities in Fractures: Effects of Flow Structures, Phase Transformation and Surface Roughness
Liquid-Gas Relative Permeabilities in Fractures: Effects of Flow Structures, Phase Transformation and Surface Roughness
Fractures are ubiquitous in the brittle lithosphere in the upper part of earth’s crust. They play a critical role in the transport of fluids. Moreover, all major discovered geothermal reservoirs and a considerable number of petroleum reservoirs are in fractured rocks. This restates the importance of studying multiphase flow behavior inside the opened fracture space. From the engineering point of view, a rock fracture as defined here is simply a complex-shaped cavity filled with fluids or solid m
