“…Among the technologies used in EOR, the use of operations to reduce interfacial tension by surfactants is implemented worldwide (Austad and Taugbøl 1995;Al-Wahaibi et al 2014;Nabipour et al 2017;Marhaendrajana et al 2018), because its ability to reduce the interfacial tension between water and oil allows the oil trapped in the pores of the reservoir by capillary forces to be recovered (Van Dyke et al 1991;Pornsunthorntawee et al 2008;Li et al 2012;Guo et al 2015;Zhang et al 2015;Kumar and Mandal 2017). However, to achieve a satisfactory result, high concentrations of surfactants are required (Sabatini et al 2000;Fernandes et al 2016), which ultimately depends upon high costs for the use of chemical surfactants.…”

In this study, the biosurfactant produced by Pseudomonas aeruginosa was evaluated in view of its ability to be used in Microbial-Enhanced Oil Recovery (MEOR). This microorganism was isolated from a soil artificially contaminated with crude oil and used to produce rhamnolipid using glycerol as the carbon source. The biosurfactant efficiently reduced water surface tension from 72 to 35.26 mN/m at its critical micelle concentration of 127 mg/L and emulsification rate (E 24) of 69% for the crude oil. Furthermore, it was demonstrated that the rhamnolipid can recover oil, even 2 months after its production, which shows that its biodegradability is not a disadvantage to the application in MEOR. The best result, for a biosurfactant concentration of 100% above the Critical Micelle Concentration (CMC) and petroleum with API gravity of 21.90, showed that the total recovery factor was 50.45 ± 0.79%, of which 11.91 ± 0.39% corresponds to MEOR.

Amphoteric surfactants have long hydrophobic hydrocarbon chain and hydrophilic positive as well as negative charged center connected with each other by a spacer group. Thus, this type of surfactant maintains overall charged neutrality. The properties of amphoteric surfactants depend primarily on the length of the hydrophobic hydrocarbon chain, the number of methylene segments in the spacer, the positive and negative charged groups, and their relative position. The ionic activity of amphoteric surfactants is influenced according to the pH value of the solvent. They display cationic behavior below the isoelectric points and anionic behavior at a higher pH. They take the shape of zwitterions in the area of the isoelectric point. In fact, amphoteric surfactants can be parted into pH‐sensitive and pH‐insensitive surfactants. The pH‐insensitive surfactants stay as zwitterionic form irrespective of the pH of the solution. This surfactant has some unique features because of its precise molecular structure as follows: high water solubility, high surface activities, a wide isoelectric range, low critical micelle concentration (CMC), high foam stability, low toxicity, low irritating, excellent biodegradability, bioactivity, interface change, and so on. Because of these special characteristics, amphoteric surfactants have been immensely interested in many applications in the scientific community, including cosmetics, chromatography, enhanced oil recovery, electrochemistry, nanoscience, polymer chemistry, and waste water treatment. This review aims to study about amphoteric surfactants, which have only one hydrophobic hydrocarbon tail and two oppositely charged hydrophilic headgroups connected with each other by a spacer group and its properties, applications in various academics and industrial fields.

“…Choosing the best surfactant (Table 4) depends on the characteristics of crude oil, brine, reservoir, and several other factors, such as pressure, temperature, compatibility, and thermal and aqueous stability [271,[321][322][323][324][325][326][327]. A successful surfactant flood should achieve sufficiently low IFT to move the trapped oil, and should maintain the stability of the surfactant slug during flooding throughout the reservoir.…”
