“…In 2023, Gholamzadeh et al studied how oil–nanofluid IFT is affected by different factors, like asphaltene content, water salinity, and SiO 2 -based NP concentration. Using a drop shape analysis to perform pendant drop measurements of oil–nanofluid IFT, they found an IFT difference of about 20 mN/m between nanofluids with and without SiO 2 -based NPs . From the extensive research conducted, the adsorption of SiO 2 -based NPs on either oil droplets or the rock surface alters the surface conditions of oil and water, which is the primary factor for decreasing oil–nanofluid IFT.…”

In recent years, nanotechnology has become increasingly important in the upstream sector of the oil and gas industry, in terms of both perspectives and practical applications. Nanoparticles, with their exceptional properties (chemical, electrical, structural, and mechanical) are proving to be useful for freeing trapped oil. Specifically, silica-based nanoparticles (SiO2-based NPs) are making a positive impact on various aspects of petroleum extraction, such as rheological and stabilization characteristics of drilling fluids, wettability alteration, interfacial tension reduction, and emulsion stability improvements. This review provides a comprehensive understanding of the applications of SiO2-based NPs in enhanced oil recovery (EOR) and the challenges associated with their use. It covers four methods of making nanoparticles, explores how SiO2-based-NP-involved nanofluids affect the EOR process, discusses the underlying mechanisms of nanoparticle-based EOR, briefly mentions how instrumentation is used in the oil and gas industry, and addresses the challenges of using SiO2-based nanoparticles in EOR, while also suggesting areas for future research.

Nanofluids have the capacity to reduce interfacial tension (IFT) of crude oil and water for enhanced oil recovery (EOR) operations, but traditional nanoparticles are limited in tight reservoirs due to their inappropriate size for micro-nano pores and their tendency to aggregate. In this paper, Graphene Quantum Dots (GQDs) with simple and favorable properties are developed, and their performance and mechanism for reducing IFT are evaluated. The paper also aims to explore the effects of GQD precursor type, synthesis duration, and molar percentages of precursors on reducing IFT. For this purpose, citric acid was used as a carbon source, and ethylenediamine, urea, and thiourea were used as nitrogen sources to synthesize different GQDs. FTIR, XPS, HR-TEM, XRD, UV visible, and PL photoluminescence were used to identify the GQDs’ characteristics. The highest IFT reduction value is achieved by using 1000 ppm ethylenediamine-derived GQDs, which reduces the IFT from 19.03 to 0.70 mN/m at 200,000 ppm NaCl concentrations without using any surfactants. The XPS analysis revealed that ethylenediamine-derived GQDs exhibit higher pyrrolic nitrogen content and a relative intensity ratio of sp3 C/sp2 C. It has been identified that the presence of more polar atomic bonds on the surfaces of GQDs decreases the ability of GQDs to reduce IFT. In this way, urea-derived and thiourea-derived GQDs exhibit less capability for IFT reductions from 19.03 to 12.33 and 18.04 mN/m at 1000 ppm GQDs and 200,000 ppm NaCl concentration, respectively. Furthermore, ethylenediamine-derived and urea-derived GQDs perform optimally at approximately 5 and 10 h, respectively, with a precursor molar ratio of 3 (mole ethylenediamine/urea per mole citric acid), while thiourea-derived GQDs show no significant IFT change with varying synthesis times or precursor molar ratio. The developed GQDs provide a promising solution for EOR operations in unconventional reservoirs by significantly decreasing the IFT between crude oil and nanofluids.
