To obtain the ultra-low interfacial tension foam flooding system for the real reservoir condition of high-temperature and high-salinity, foam properties and dynamic interfacial tension had been performed by Ross-miles test and spin drop tension meter respectively. Ten types of surfactants were screened by foamability, stability and interfacial tension (IFT) at 85°C, high-salinity with 800 mg/L divalent cations and 30000 mg/L total mineralization. The AOS, AESO and 20YB were selected to compose further anion-nonionic mixture system. Due to AOS had excellent foam properties, AESO could achieve low interfacial tension and 20YB could improve the film quality. Through series complex study, the ultra-low interfacial tension (10-4 mN/m order of magnitude) foam system was obtained with the composition of 0.15% wt AOS+0.15% wt AESO+0.11%~0.012% wt 20YB for high-temperature and high-salinity, which V foam was 240-235 mL and t 0.5 was 180-190 min. In addition, the synergistic effect of these surfactants had been described.

Internal Olefin Sulfonate

Surfactant ultra-low interfacial tension (IFT) for internal olefin sulfonate with iso-amylalcohol (IAA) as co-solvent against heptane, octane and decane at 20 °C, 50 °C, and 90 °C respectively have been systematically investigated, as well as the dynamic retention in porous media. The results show for oils with alkane carbon number from 7 to 10 and temperature from 20 °C to 90 °C, optimal salinity starts from 6.5 wt% to 11.6 wt% NaCl, where ultra-low IFT occurs. While at high salinity (at least from 6 wt% NaCl ), the retention is too high for surfactant flooding to be applicable. Only internal olefin sulfonate with co-solvent alone can not provide a perfect formulation with ultra-low IFT and low retention.
