CO2 has the ability to produce foam when in contact with suitable surfactants. In the presence of an adequately stable foam CO 2 has more opportunity to invade by-passed oil and capillary trapped oil in the pores of an oil reservoir. As a result more oil can be recovered. It is essential that the foam possesses the endurance and resistance against oil. The performance of the CO 2 foam for oil displacement is influenced by rock and fluid properties and interactions, rock heterogeneity, injection strategy, and type and structure of the surfactant. A structure-performance relationship of the foaming surfactant is emphasized in this report. A review of the CO 2 foam performance and experiments conducted to identify key success factors of a superior CO 2 foam for enhanced oil recovery is elaborated. A surfactant which has an affinity for CO 2 and water and at the same time repels oil is desired. Knowledge of the CO 2 - surfactant solution-oil interaction is essential to the design of a successful CO 2 foam surfactant.
