“…Cao et al prepared nanofluids containing a polyoxyethylene Janus graphene oxide based material (P-GO-O) with a hydrophilic surface of polyoxyethylene and a hydrophobic surface of octadecyl. 43 P-GO-O nanofluid is able to reduce oil–water IFT to 12.2 mN m −1 and has excellent wettability reversal ability. The oil recovery rate of P-GO-O nanofluid (17.2%) is higher than other NFs due to its good stability and wettability reversal ability.…”

“…Four phenomena occur when nanofluid is introduced into porous media: adsorption, desorption, blockage, and migration with flowing fluid. This section introduces one proposed model that others have recently adopted for nanofluid injection in oil reservoirs for EOR [ 69 , 70 , 71 , 72 ].…”

It is necessary to sustain energy from an external reservoir or employ advanced technologies to enhance oil recovery. A greater volume of oil may be recovered by employing nanofluid flooding. In this study, we investigated oil extraction in a two-phase incompressible fluid in a two-dimensional rectangular porous homogenous area filled with oil and having no capillary pressure. The governing equations that were derived from Darcy’s law and the mass conservation law were solved using the finite element method. Compared to earlier research, a more efficient numerical model is proposed here. The proposed model allows for the cost-effective study of heating-based inlet fluid in enhanced oil recovery (EOR) and uses the empirical correlations of the nanofluid thermophysical properties on the relative permeability equations of the nanofluid and oil, so it is more accurate than other models to determine the higher recovery factor of one nanoparticle compared to other nanoparticles. Next, the effect of nanoparticle volume fraction on flooding was evaluated. EOR via nanofluid flooding processes and the effect of the intake temperatures (300 and 350 K) were also simulated by comparing three nanoparticles: SiO2, Al2O3, and CuO. The results show that adding nanoparticles (<5 v%) to a base fluid enhanced the oil recovery by more than 20%. Increasing the inlet temperature enhanced the oil recovery due to changes in viscosity and density of oil. Increasing the relative permeability of nanofluid while simultaneously reducing the relative permeability of oil due to the presence of nanoparticles was the primary reason for EOR.

“…According to a micromodel test, the nanofluid oil recovery of 0.1 wt % functionalized nanohybrids increases by 53, 71, and 83% with the addition of more oxygen-containing functional groups. N-GQDs/MoS 2 nanohybrids were reported to be able to alter the wettability of carbonate rocks from oil-wet to water-wet conditions by AfzaliTabar et al Furthermore, GO–dodecylamine, GO–ethylenediamine, GO–NH 2 –PEG–OH, and GO–polymer are a few other examples of functional graphene oxide that are used in the study of EOR. − …”

Nanomaterials have shown significant performances in enhancing oil recovery by reducing the interfacial tension (IFT) and contact angle (CA) of the rock/crude oil/water system in porous media. This is evaluated by the synergistic impact of silica− graphene quantum dots (Si−GQDs) on IFT reduction and wettability alteration for the purpose of enhancing oil recovery from carbonate reservoirs. The silica−graphene quantum dots (Si− GQDs) were synthesized by combining graphene oxide and silicon oxide nanoparticles (NPs) and characterized using several analytical techniques. Both distilled water and brine, as dispersion media, were used to prepare nanofluids by dispersing the synthesized Si− GQDs at different concentrations from 1000 to 10,000 ppm. The main properties of the nanofluids including pH, density, and conductivity were measured to evaluate their quality and the performance of Si−GQDs. In addition, the prepared nanofluids were used in the measurements of IFT and contact angles at different concentrations of the synthesized Si−GQDs in both types of used water. The obtained results show that the DWN1000 nanofluid formulated from dispersing 1000 ppm Si−GQDs in distilled water enables an additional 14.4% OOIP oil recovery due to a significant reduction in the value of IFT from 28.3 to 9.5 mN m −1 , improving rheology behavior and wettability alteration toward a strong water-wet system from 134 to 61°contact angles.
