Enhanced Oil Recovery Field Case Studies: Chapter 8. Alkaline-Surfactant Flooding

This chapter discusses about these interactions between alkali and surfactant: (1) addition of an alkali in a surfactant solution equivalently adds salt; (2) addition of an alkali in a surfactant solution changes the surfactant phase behavior; and (3) addition of an alkali in a surfactant solution reduces surfactant adsorption. After presenting those fundamentals, two field pilots are presented: Big Sinking field in East Kentucky and White Castle field in Louisiana.
