... and high temperatures due to their limited stability. Our objective is to introduce a novel alkyl ether carboxylate (AEC) based surfactant which exhibits both an outstanding tolerance against high temperatures and high salt concentrations, while delivering high interfacial activity. The solubility...

... reservoirs. Previous studies have been reported that polymers, polymer gel and inorganic particles (silica nanoparticles, etc.) have been used as external phase to enhance foam stability ( G. Zhao, et al., 2015 ; Q. You, et al., 2009 ; C. Huh, et al., 2008 ; P. B. Bernard and S.H. Tommy, 2005; S. Qian, et...

... that, in both static and dynamic studies, the PEF had higher stability than that of foams. Nonionic surfactant generated the least stable foam in the presence of crude oil. Surfactant flooding slightly increased the oil recovery from matrix after water injection. This was more evident in the case of CTAB...
