Three-Phase Flow in Porous Media & Phase Equilibrium — Lesson 7

This lesson covers the concept of flow through porous media, focusing on three-phase flow where there is interaction between liquid and gas. It explains the use of formation volume factor terms and solution gas oil ratio to simplify phase equilibrium. The lesson also discusses the density at reservoir conditions, the concept of stock tank conditions, and the relationship between these factors. It further delves into the volume balance equation under stock tank conditions and the changes in saturation over time due to the flow of oil, water, and gas. The lesson concludes with the explanation of the continuity equation for three different phases and the importance of solving these equations for three-phase flow.
