“…The selection of NPs for EOR plays a crucial role in achieving optimal results . Typical NPs used in EOR operations are carbon-based and metal-based nanomaterials . Carbon-based nanomaterials such as graphene and carbon nanotubes possess exceptional mechanical strength and are resistant to corrosion, making them effective in enhancing oil recovery in both sandstone and carbonate reservoirs. , On the other hand, metal-based NPs composed of metal oxides have become increasingly popular in EOR research and operations .…”

In this study, we investigate the effects of highly surfacemodified silica nanoparticles (NPs) on rock−fluid interactions and imbibition oil recovery from tight rocks. The protocol consists of the following steps: (1) measuring the fluid properties of NP solutions, including interfacial tension (IFT), particle size distribution, and zeta potential; (2) evaluating the efficiency of NPs on wettability change and enhanced oil recovery by conducting systematic contact angle and imbibition tests; (3) visualizing NP adsorption on rock surfaces before and after NP treatment through SEM/ EDS analysis; and (4) evaluating the change of adhesion forces between a silica tip and the rock surface with and without NPs using atomic force microscopy analysis. Our results indicate that adding NPs reduces oil−water IFT values from 15 to less than 4 mN/m, and alters the initial natural-wet rocks toward more water-wet. The IFT reduction and wettability alteration can explain the improved oil recovery by NP solutions. Compared to the base cases with less than 10% oil recovery factor, the oil recovery factor from the oil-saturated samples soaked in NP solutions is enhanced, ranging from 15.2 to 26.1%. Increasing the concentration of NPs beyond the critical micelle concentration results in more oil recovery because a higher NP concentration ensures a sufficient supply for the extensive pore surfaces in tight rocks. Increasing salinity results in less oil recovery due to weaker osmosis and less wettability alteration and an enhanced cation bridging effect. Based on the interaction energy calculation for the rock−water−NPs system using the DLVO theory, NP adsorption primarily occurs on carbonate or hydrocarbon residue surfaces. The adsorption of NPs on the rock surface is proportional to NP concentrations, and the adhesion force between the rock surface and the silica tip increases after NP adsorption. This can be explained by higher adhesion energy between the rock surface and NPs obtained from the interaction energy profiles. By increasing salinity, the energy barrier for NPs to adsorb on the rock surface reduces, enhancing NP adsorption.

As a "green" displacing agent, nanocellulose is enriched, nontoxic, biodegradable, and environmentally friendly; therefore, the development and potential application of nanocellulose in oilfield chemistry have attracted widespread attention in recent years. In this study, a thermothickening copolymer synthesized in our laboratory called hydroxypropyl methyl cellulose-based graft (PHAD) copolymer was chosen to mix with Halocynthia roretzi Drasche-based cellulose nanocrystals (TCNCs), and anionic surfactant sodium dodecyl sulfate (SDS) was added to improve the stability of the displacing agent. After the optimal SDS concentration was confirmed, PHAD/TCNCs/ SDS dispersions containing 0.05−0.15 wt % TCNCs can be stable for a long time. Hence, the rheological performance of dispersions containing 0.05−0.15 wt % TCNCs was investigated systematically, and the results revealed that the PHAD/TCNCs/SDS dispersions had outstanding thermothickening ability, salt resistance, shear resistance, and viscoelastic property in a simulated oil reservoir circumstance, and the interaction mechanism among PHAD, TCNCs, and SDS was analyzed. Finally, a core flooding test was conducted, and the obtained data showed that the oil recovery of dispersion was 21.5%, which is higher than the control dispersion without TCNCs, confirming that the PHAD/TCNCs/SDS dispersions have significant practical application prospects.

“…Currently, the plentiful hydrophilic groups, including hydroxyl and carboxyl groups, present on the surface of traditional carbon dot nanomaterials exhibit certain restrictions regarding their interfacial activity. The composite system of carbon nanomaterials and surfactants is prone to a chromatographic separation effect, and the system is unstable. − It is crucial for developing carbon-based nanofluids with ultrasmall size and excellent interfacial activity by directly modifying the surface of carbon dot nanomaterials.…”

Carbon dot nanomaterials (<10 nm) exhibit superior application prospects as oil displacement materials for unconventional reservoir development. However, the limited oil−water and oil−solid interfacial activity of carbon dot nanomaterials restricts their broader application. In this study, carbon dot nanomaterials (CDs) are expeditiously prepared via a microwave-assisted synthesis method utilizing urea and citric acid as precursor compounds. OAB-modified active carbon dot nanomaterials (OCDs) are prepared by grafting oleic acid amidopropyl betaine (OAB) through hydrothermal reaction at 90 °C for 5 h using CDs as a carbon dot carrier. Stability experiments show that the plentiful hydrophilic groups present on the surface of the OCD augment electrostatic repulsion among them, thereby imparting dispersibility, temperature tolerance (90 °C), and salt resistance (2.6 × 10 4 mg/L). Additionally, OCDs demonstrate optimal effectiveness at a concentration of 0.5 wt %. At this concentration, OCDs can reduce the interfacial tension to 0.66 mN/m and achieve the underwater oil contact angle to 126°. Within 24 h, OCDs can strip 60.6% of the oil film. OCDs show the excellent ability to enhance oil−water and oil−solid interfacial activity. Meanwhile, OCD nanofluids can effectively form emulsions with crude oil and spontaneously demulsify within 2 h in a state. Core flooding tests demonstrate that OCD nanofluids, when compared with simulated formation water, reduce injection pressure by 46.3% and enhance oil recovery by 31.1%. This study offers a promising solution for the efficient development of unconventional reservoirs with carbon dot nanomaterials.
