“…They found that plenty of anionic surfactants were located in the interspace of alkyl sulfobetaine hydrophobic chains to enhance the interfacial compactness . Similar results were also found in the experiments, and the mixed anionic/cationic surfactant systems could form the adsorption layer with a denser arrangement at the oil–water interface. − The physical and chemical properties of surfactant emulsions eventually were improved and available on-demand for practical applications. − …”

“…Previous studies have developed a series of zwitterionic molecules as the surfactants to form the high surface-active mixtures, mainly focused on their ability to reduce IFT, emulsifying characteristics for oil–water systems with the relatively low viscosity. ,,− Herein, we constructed a mixed synergistic emulsion system by introducing the zwitterionic cocoamidopropyl sulfonate betaine (CSB) and anionic sodium dodecyl benzene sulfonate (SDBS). The performance of the mixed systems on heavy oil emulsions was studied in terms of surface tension, IFT, droplet size distribution, apparent viscosity, emulsion stability, viscosity reduction, and viscoelasticity.…”

Conventional water flooding strategy has limited the further development of heavy oil recovery due to the lower displacement efficiency. In this work, a potential zwitterionic/anionic surfactant system to enhance heavy oil recovery in the high salinity was proposed through low budget and feasible mixing. We evaluated the capabilities of the mixed surfactant systems consisting of zwitterionic cocoamidopropyl sulfonate betaine (CSB) and anionic sodium dodecyl benzene sulfonate (SDBS) in terms of surface tension, interfacial tension (IFT), emulsion size distribution, emulsion stability, apparent viscosity, emulsion viscoelasticity, viscosity reduction, and recovery efficiency. The IFT could substantially reduce to an ultralow level (<10 −2 mN/m) at a higher salinity. The smaller droplets (0.1−3 μm) were formed to stabilize the heavy oil emulsions. The viscoelasticity test confirmed that the intensity of the interface film was enhanced because SDBS/CSB molecules could coabsorb at the heavy oil−water interface in a most closely packed arrangement. Furthermore, the water flooding experiments with different surfactant systems were also implemented to affirm the great potential of the synergetic surfactant systems for heavy oil recovery.

Measurements of the surface tension of the aqueous solution of SDDS mixture with fluorocarbon surfactants (FC) were carried out and considered in light of the surface tension of aqueous solutions of individual surfactants. Similar analyses were made for many other aqueous solutions of binary and ternary mixtures, taking into account the literature data of the surface tension of aqueous solutions of TX100, TX114, TX165, SDDS, SDS, CTAB, CPyB and FC. The possibility of predicting the surface tension of the aqueous solution of many surfactant mixtures from that of the mixture components using both the Szyszkowski, Fainerman and Miller and Joos concepts was analyzed. The surface tension of the aqueous solutions of surfactant mixtures was also considered based on the particular mixture component contribution to the water surface tension reduction. As a result, the composition of the mixed surface layer at the solution–air interface was discussed and compared to that which was determined using the Hua and Rosen concept. As follows from considerations, the surface tension of the aqueous solution of binary and ternary surfactant mixtures can be described and/or predicted.
