“…In the FTIR spectrum (Fig. ) of the zwitterionic surfactant before aging, the two stretching vibrations at 2920 and 2849 cm −1 were seen corresponding to the methyl (–CH 3 ) and methylene (–CH 2 –) groups in the hydrophobic tail (Dardir, Mohamed, Farag, Ramdan, & Fayad, ; El‐Lateef, Abo‐Riya, & Tantawy, ; Shaban, Aiad, Fetouh, & Maher, ). The stretching vibration of the carbonyl group was observed at 1641 cm −1 and C–N stretching vibration was detected at 1070 cm −1 (Zaky, Badawi, El Sabbah, Ghani, & Hendawy, ).…”

High-temperature/high-salinity (HTHS) reservoirs contain a significant fraction of the world's remaining oil in place and are potential candidates for enhanced oil recovery (EOR). Selection of suitable surfactants for such reservoirs is a challenging task. In this work, two synthesized zwitterionic surfactants bearing a saturated and an unsaturated tail, namely 3-(N-stearamidopropyl-N,N-dimethyl ammonium) propanesulfonate and 3-(N-oleamidopropyl-N,N-dimethyl ammonium) propanesulfonate, respectively, were evaluated. The surfactant with the unsaturated tail showed excellent solubility in synthetic seawater (57,643 ppm) and in formation brine (213,734 ppm). However, the unsaturated surfactant with a saturated tail showed poor solubility, and therefore it was not evaluated further. The thermal stability of the synthesized unsaturated surfactant solution in seawater was evaluated by heating the solution at 90 C in a sealed aging tube for 2 weeks. The thermal stability of the unsaturated surfactant was confirmed by FTIR and NMR analysis of the aged samples at such harsh conditions. The critical micelle concentration (CMC) of the synthesized unsaturated surfactant in seawater was 1.02 × 10 −4 mol L −1 , while the surface tension at CMC was 30 mN m −1 . The synthesized unsaturated surfactant was able to reduce the oil-water interfacial tension tõ 10 −1 mN m −1 at different conditions. A commercial copolymer of acrylamide and 2-acrylamido-2-methylpropane sulfonic acid (AM-AMPS) was tested for EOR applications in HTHS conditions. The addition of the synthesized unsaturated surfactant to the AM-AMPS copolymer increased the viscosity of the system. The increase in oil recovery by injecting the unsaturated surfactant solution and the surfactant-polymer mixture in solution was 8 and 21%, respectively. The excellent properties of the synthesized unsaturated surfactant show that surfactants with an unsaturated tail can be an excellent choice for HTHS reservoirs.

“…Every concentration was measured in triplicate with a 5 min interval and the average was considered. The interfacial tension measurements were performed on the same instrument using 10 mL (0.1%) aqueous solutions of DBAO, DBAD, and DBAH surfactants and light paraffin oil at 25 C (Dardir et al, 2017;Negm et al, 2009). CMC values were also determined using conductivity and UV-Vis spectroscopy.…”

The surface parameters of some cationic surfactants having different hydrophobic alkyl chains were assessed in aqueous solution using different techniques; surface tension, ultraviolet‐Visible (UV–Vis) spectroscopy, and conductivity measurements. The obtained critical micelle concentration (CMC) for N‐(2‐((3,4‐dimethoxybenzylidene)amino)ethyl)‐N,N‐dimethyloctan‐1‐aminium bromide (DBAO), N‐(2‐((3,4‐dimethoxybenzylidene)amino)ethyl)‐N,N‐dimethyldodectan‐1‐aminium bromide (DBAD), and N‐(2‐((3,4‐dimethoxybenzylidene)amino)ethyl)‐N,N‐dimethylhexadectan‐1‐aminium bromide (DBAH) in aqueous solution using three techniques are nearly the same. Increasing the hydrophobic chain length enhances micelle formation. Raising the solution temperature from 25 to 65 °C also shows the same trend. The thermodynamic calculations outlined the adsorption propensity of the surfactants at the surface compared to their affinity to form micelles. Both micellization and adsorption processes are enhanced with both the hydrocarbon elongation and with raising the solution temperature. The effect of the surfactant tail on the preparation process of the silver nanoparticles (AgNP) was assessed and confirmed using transmission electron microscope (TEM), dynamic light scattering (DLS), and UV–Vis spectra. Increasing the surfactant tail leads to a smaller particle size with a narrow distribution. The stability of the prepared AgNP is enhanced with hydrophobic surfactant tail elongation as proved with increasing the zeta‐potential of the prepared AgNP colloid. The foaming power, interfacial tension, and emulsification stability of the DBAO, DBAD, and DBAH surfactants were determined. The DBAO, DBAD, and DBAH surfactants showed good antimicrobial activities against both bacteria (Gram positive and negative) and fungi, which have been enhanced because of incorporation of AgNP.
