“…This means that both surfactant and NPs support each other for injected emulsion stability. In addition, the stability against sedimentation increases in solutions due to NPs that can balance the surface forces and the force of gravity [71][72][73][74][75][76].…”

Nanoparticles (NPs) are known as important nanomaterials for a broad range of commercial and research applications owing to their physical characteristics and properties. Currently, the demand for NPs for use in enhanced oil recovery (EOR) is very high. The use of NPs can drastically benefit EOR by changing the wettability of the rock, improving the mobility of the oil drop and decreasing the interfacial tension (IFT) between oil/water. This paper focuses on a review of the application of NPs in the flooding process, the effect of NPs on wettability and the IFT. The study also presents a review of several investigations about the most common NPs, their physical and mechanical properties and benefits in EOR.

“…Subsequently, IFT, adsorption, and core flood studies should be performed to gain insight into macroscale additional oil recovery performance of the surfactant. A judgment on pilot testing and field implementation can be taken based on oil recovery and other laboratory data, as well as the cost and availability of the surfactants. − The future of screening of surfactants will witness the use of micromodels. Microfluidics provide a way to visualize the pore-scale events during the displacement process.…”

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.

With escalating global energy demands and the depletion of conventional oil reserves, the exploitation of unconventional oil reservoirs necessitates advanced recovery materials. Nanomaterials, due to their substantial surface-to-volume ratio and elevated surface energy, emerge as potential solutions to the challenges of ultralow permeability and intricate pore structures in these reservoirs. Despite copious laboratory research on nanosolid particles, nanosurfactants, and nanoemulsions, field data regarding their use in unconventional reservoirs remains scarce, hindering the development of a selection mechanism for optimal nanomaterial utilization across different production stages. Consequently, an exhaustive investigation into the characteristics, mechanisms, and field trial data of nanomaterials is paramount for enhancing recovery rates and economic efficiency and guiding the broader application of these materials in unconventional reservoirs. Therefore, this work reviews the characteristics and pros and cons of various nanomaterials in application. It elucidates several mechanisms of nanomaterials in enhancing recovery rates, such as increasing the viscosity of the injection fluid, reducing interfacial tension, changing rock wettability, especially altering oil flow, promoting spontaneous imbibition and expanding sweep efficiency. Furthermore, the paper also integrates the field application cases of the independently developed nanoemulsion in unconventional oil areas of shale in Xinjiang and tight oil in Jilin, China, to emphasize and illustrate the importance of matching different nanomaterials according to different stage extraction characteristics. Finally, this work looks forward to future research, advocating for a deeper understanding of the behavior of nanomaterials in unconventional oil reservoirs through the combination of physical and numerical simulation experiments, to optimize their performance and applicability in a wider industrial environment.
