Buckley-Leverett theory

Buckley-Leverett theory describes how fluids, like water and oil, move through porous rocks in a reservoir. It predicts the way the displacing fluid pushes the displaced fluid, resulting in a sharp front or interface between the two. The theory helps estimate how much oil can be recovered and how fast the displacement occurs by analyzing the balance between flow rates and fluid properties. It accounts for phenomena like capillary effects and differences in fluid mobility, providing a vital tool for optimizing oil recovery processes in petroleum engineering.
