It has been shown that molecular surfactant structure is an important variable to deal with when making up a surfactant formulation for tertiary oil recovery processes. Thus, a fluorescent probe technique was used to gain information on the different micelles formed by 2 series of isomeric surfactants: sodium dodecylbenzenesulfonates and sodium hexadecylbenzenesulfonates. It was found that the microviscosity in the vicinity of benzene moiety (intrinsic probe) varies with surfactant structure. This behavior was explained by the interrelationship between 2 opposing effects: the short alkyl chain effect and the long alkyl chain effect. Also, variation of the degree of polarization with temperature was used for determning clear points of different surfactant-NaCl-H/sub 2/O systems. This clear point property which corresponds to the clear-to-turbid transition was found to depend on surfactant structure, surfactant molecular weight and was shown to be reversible. The effect of temperature on aqueous micellar solutions showed a decrease in the degree of polarization with increasing temperature.
