Abstract

Flooding with surfactant-based microemulsions is one of the promising techniques for enhancing petroleum recovery from natural deposits, or reservoirs(1). By microemulsion we mean a thermodynamically stable, microstructured fluid phase of variable composition that incorporates substantial amounts of oil, water and surfactants. The phase behaviour, interfacial tensions, and rheological properties of a microemulsion formulation are among the primary determinants of the potential success of a microemulsion flood. Because the number of equilibrium phases, their volumes and their appearances are easier to measure and observe than phase compositions, viscosities and interfacial tensions, there is obvious interest in understanding the relationship between the phase counts, volumes and appearances and the other physical properties of microemulsions(2,3).
