In fluid dynamics, the Buckley–Leverett equation is a conservation equation used to model two-phase flow in porous media. The Buckley–Leverett equation or the Buckley–Leverett displacement describes an immiscible displacement process, such as the displacement of oil by water, in a one-dimensional or quasi-one-dimensional reservoir. Waterflood displacement efficiency is affected by the viscosity ratio of the displaced to the displacing fluid. Therefore, the oil recovered in a water flooding process is largely determined by the viscosity ratio. This paper presents a quantitative analysis of the viscosity effects on oil recovery in a linear system using Buckley-Leverett equation and other related mathematical models to
