The abstraction behavior of purified Nadodecylbenzenesulfonate on Na-Kaolinite by step-wise increase in surfactant concentration is determined. Deabstraction upon reductions in surfactant at various stages is also determined. Most importantly, the results of incremental abstraction, individual abstraction, and deabstraction showed the system to exhibit hysteresis or memory effects. Also, abstraction obtained at various pH values and during step-wise changes in pH exhibited marked differences between them. The deabstraction isotherms showed the presence of maximum in certain cases, indicating the occurrence of maximum on the abstraction isotherms to be a real phenomenon. Possible reasons for the hysteresis are considered and the partical implications of the above memory effects on micellar flooding ad the validity of the data obtained for surfactant depletion from experiments using cores preflushed with different chemicals are discussed. 15 refs.
