With a constant upsurge in energy demand, production from depleted and harsh reservoirs through enhanced oil recovery techniques (EOR) has significantly increased. Among many EOR techniques, chemical EOR (cEOR) is one of the most widely used methods of oil extraction. Surfactants used in cEOR are instrumental in reducing interfacial tension (IFT) and altering the wettability of rock, which leads to additional oil recovery. This review draws attention to detail on surfactants from fundamentals to field scale. Properties of surfactants like phase behaviors, critical micelle concentration (CMC), hydrophilic–lipophilic balance and deviation, zeta potential, and their importance are discussed in depth. The presence of a saline environment, polymer, cosurfactant, and other factors affecting the performance of surfactant during the cEOR process are also elaborated. Key findings on surfactant adsorption on reservoir rock with other influencing aspects have also been reported in this study. Types of surfactants, from basic to the likes of polymeric, viscoelastic, Gemini, natural, and their effects on oil recoveries have been analyzed and compared. Special emphasis on emerging aids for surfactant flooding such as applications of nanotechnology, use amphoteric Janus particles, and synergies of surfactant–low salinity water flooding, along with their mechanisms and recent advances have been thoroughly duscussed. Lastly, the review delineates discerning criteria for the selection of surfactants, reviews recent field applications, and outlines the challenges that the industry faces while implementing surfactant cEOR. It has been found that exhaustive studies have been conducted on sandstones with success. However, extreme temperature and saline conditions in the case of carbonate reservoirs limit the applicability of surfactants, and the pursuit to accomplish its efficacy continues.

“…From a practical point of view, the transitions of ME from one type to another and their behavior are explained using the Winsor phase concept and pseudoternary phase diagrams. The study of the internal structure of microemulsions represents an important area in the research of ME thermodynamics [ 172 , 173 , 174 ].…”

With a fascinating complexity, governed by multiple physiological processes, the skin is considered a mantle with protective functions which during lifetime are frequently impaired, triggering dermatologic disorders. As one of the most prevalent dermatologic conditions worldwide, characterized by a complex pathogenesis and a high recurrence, acne can affect the patient’s quality of life. Smart topical vehicles represent a good option in the treatment of a versatile skin condition. By surpassing the stratum corneum known for diffusional resistance, a superior topical bioavailability can be obtained at the affected place. In this direction, the literature study presents microemulsions as a part of a condensed group of modern formulations. Microemulsions are appreciated for their superior profile in matters of drug delivery, especially for challenging substances with hydrophilic or lipophilic structures. Formulated as transparent and thermodynamically stable systems, using simplified methods of preparation, microemulsions have a simple and clear appearance. Their unique structures can be explained as a function of the formulation parameters which were found to be the mainstay of a targeted therapy.

“…For enhanced oil recovery, type III microemulsions (Winsor III) are generally desired because the spontaneous curvature of the surfactant film approaches net zero and leads to the lowest IFT values among other types of microemulsion systems [17,18]. Therefore, in order to develop a suitable technology for MEOR processes, it is essential to study the formation and phase behavior of microemulsion systems.…”

Recently, nanoparticles have become an attractive agent for enhanced oil recovery (EOR). Because much of the work on nanoparticles for enhanced oil recovery is still at the laboratory stage and to gain a better understanding of this technique, it is essential to study the effect of nanoparticles on EOR. In addition, the world is now more environmentally aware, presenting the opportunity to use biosurfactants for EOR. In this paper, the synergistic effect of biosurfactant and nanoparticles on the removal of oil in a glass micromodel was evaluated. In this study, an aqueous solution of emulsan biosurfactant with addition of SiO 2 nanoparticles was used as a nanofluid. The emulsan biosurfactant was produced by Acinetobacter calcoaceticus PTCC1318. The production of emulsan was confirmed by FTIR and 1 H NMR analysis. According to our results, the use of the mixture of biosurfactant and nanoparticle (nanofluid) permitted a 90% reduction of interfacial tension in comparison with biosurfactant solution alone. Micromodel oil displacement experiments with kerosene showed around 10 and 20% recovery of residual oil after water flooding when the emulsan and nanofluid were injected, respectively. These results are useful in extending the application of nanostructures in ex situ microbial enhanced oil recovery.
