Title: Aspects of Relative Permeability: Theory, Applications and Limitations
Abstract:
Relative permeability is commonly used to upscale and model immiscible fluid flow in porous media through a multi-phase extension of Darcy’s law. The fundamental concepts and practical use of relative permeability have been well established for decades, but their arguments are mostly phenomenological.
Multiphase flow in porous media is strongly influenced by the pore-scale mechanisms and in-situ arrangement of fluids. How fluids are distributed and transported are dependent on the pore structures in addition to wettability, fluid-fluid interactions, and external boundaries. All these effects weigh in on the interpretation of relative permeability and the resulting constitutive relationships. In this talk, I will present some perspectives on the use of relative permeability from theoretical and application points of views. These will range from fundamental perspectives based on energy conservation to practical uses in up-scaling and reservoir characterization. I will also treat some of the limitations of the concepts and how new emerging theories fit into the understanding
