Most glaringly, it obscures the very useful role that saturations have in constraining permeability modelling and identifying reservoir compartments. "Transition zones" focus on saturation and take emphasis away from relative permeability...

In this paper, a numerical method, which is based on the mimetic finite difference method (MFD) and digital rock analysis (DRA), is proposed for relative permeability upscaling. The validation of MFD is tested by two different cases with exact pressure solution. Then, the relative...

... Abstract Gas-water relative permeability curve is critical in reservoir simulation and development for tight reservoirs. It is generally obtained from unsteady-state flow experiment under lab condition (i.e., room temperature and normal pressure). The measured results often significantly differ...

... Abstract To ensure the physics of multiphase flow in porous media is rightly modelled, the balance between capillary, viscous, and gravity forces need to be understood. Capillary pressure (Pc) and relative permeability (kr) are critical parameters representing capillary and viscous forces...
