Buckley Leverett Front & Immiscible Flow Calculations — Lesson 6

This lesson covers the concept of flow through porous media, focusing on the Buckley Leverett front theory and the implications of gas phase presence and vapour liquid interaction. It explains the geometric construction of f_W versus S_W curve and the role of relative permeability in determining the volumetric flow of water and oil. The lesson also discusses the concept of formation volume factor in reservoir modelling and the importance of phase equilibria thermodynamics in determining the volume of gas under different conditions. It provides a comprehensive understanding of the continuity equations for oil, water, and gas in a porous medium.
