“…Nanotechnology has drawn the attention of the researchers toward the application of nanofluid/nanofluids (NF/NFs) for various oil field applications, including oil recovery, to overcome the limitations observed in the traditional methods. − Silica nanoparticles have shown their promising role in stabilizing the oil–water emulsion formed when injection fluid containing a surfactant comes in contact with reservoir fluids. The stable microemulsion formed in the presence of NPs with various surfactants helps to achieve the ultralow IFT of an oil–water system .…”

Low salinity water injection (LSWI) has gained popularity recently as a potential enhanced oil recovery (EOR) method. The efficiency of LSWI can be improved with the advent of nanotechnology. Nanofluids can alter the wettability of the solid surface from intermediate-wet to water-wet, a condition most favorable to enhance the oil displacement efficiency. Studies have been reported in the literature on the use of nanoparticles and surfactants with LSWI mainly for carbonate rock and synthesized saline water containing mainly sodium salt; however, not much information is available for sandstone rock and the use of low saline seawater (LowSal). Also, a comparative study on the use of silica and kaolinite nanofluids in LowSal has not yet been explored in detail to understand their impact on the wettability alteration and interfacial tension (IFT) of the oil−nanofluid−rock system. Thus, in this work, silica and kaolinite nanofluids have been prepared in LowSal with varying concentrations (0−2000 ppm) without and with an anionic surfactant, dioctyl sodium sulfosuccinate (AOT), to assess their impact on the IFT and wettability alternation (through contact angle measurements) of the oil−nanofluid−rock system. Three different oil samples, viz., model oil A, model oil B, and light crude oil to represent acidic, basic, and weakly basic oil systems, respectively, have been considered. An intermediate-wet quartz plate is used to mimic the properties of the sandstone rock. A detailed mechanism has been highlighted to ascertain the impact of nanofluids on the IFT and wettability alteration of the representative rock sample from an intermediate-wet to water-wet condition based on the Gibbs adsorption isotherm, scanning electron microscopy (SEM), and energy-dispersive X-ray (EDXA/EDS/EDX) studies. The results are outlined to understand the possible future applications of silica and kaolinite nanofluids for enhanced oil recovery processes.

“…Nanotechnology has played an important role in the evolution of modern technologies including the oil and gas industry. The upstream hydrocarbon industry has seen significant research and application of nanotechnology pertaining to areas of EOR, drilling fluids, oil–water separation, coatings, and flow assurance. − In EOR, the synergetic use of nanoparticles (NPs) and surfactants can improve the process of oil recovery by many folds. Some of the studies have functionalized surfactant parts with the nanoparticle to enhance diffusion into an oil–water interface, alter wettability, or reduce IFT.…”

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.
