Summary A new family of anionic surfactants that has great potential for enhanced-oil-recovery (EOR) applications was synthesized and characterized in our laboratory. The unique and versatile structure of these surfactants has endowed them with properties that are attractive for EOR. A detailed experimental study was carried out and is presented here on the oil/water and solid/water interfacial properties of seven novel molecules. The interfacial properties of this series of seven anionic surfactants with different lengths of hydrophobic tail and linking spacer group show systematic trends in interfacial tension (IFT) and static adsorption density with changes in solution conditions. These molecules showed excellent aqueous stability even in high-salinity and hard brines. Ultralow IFT (ULIFT) values were measured at low surfactant concentrations. The synthesized Gemini surfactants also showed lower maximal adsorption densities than the conventional single-chain surfactants. The results from this study showed the potential of using these surfactants at low concentrations and in harsh reservoir conditions.

Alkylaryl sulfonate is a typical family of surfactants used for chemically enhanced oil recovery (EOR). While it has been widely used in surfactant–polymer flooding at Karamay Oilfield (40 °C, salinity 14,000 mg/L), its aggregation behavior in aqueous solutions and the contribution of aggregation to EOR have not been investigated so far. In this study, raw naphthenic arylsulfonate (NAS) and its purified derivatives, alkylaryl monosulfonate (AMS) and alkylaryl disulfonate (ADS), were examined under simulated temperature and salinity environment of Karamay reservoirs for their micellar aggregation behavior through measuring surface tension, micellar size, and micellar aggregation number. It was found that all three alkylaryl sulfonate surfactants could significantly lower the surface tension of their aqueous solutions. Also, it has been noted that an elevation both in temperature and salinity reduced the surface tension and critical micellar concentration. The results promote understanding of the performance of NAS and screening surfactants in EOR.
