“…Therefore, the penetration of NPs through the reservoir can occur easily without severe impact on the permeability (Peng et al 2017;Maurya et al 2017). Additionally, NPs can increase the viscosity of the injected fluids, reduce the interfacial tension (IFT) between two immiscible phases (Ali et al 2018;Bagherpour et al 2019), change the wettability of porous media to more water wet state and function effectively in oil recovery (Bagherpour et al 2019;Eshraghi et al 2017;Yousefvand and Jafari 2018).…”

Silica nanoparticles (NPs) have been synthesized by titration of potassium silicate with hydrochloric acid, characterized and the effects of process parameters on size and morphology have been investigated. The size of the NPs decreased with increasing temperature and potassium silicate concentration. Central composite design (CCD) was applied to systematically determine the most significant factors affecting the particle size and optimize the experimental conditions to achieve minimum particle size. The optimal experimental conditions were obtained at hydrochloric acid concentration of 0.6 M, potassium silicate concentration of 11.85 wt% and temperature of 63.3 °C. SEM images proved that the pH and temperature shifted the NPs to non-spherical morphologies. To identify the effect of NPs morphology on oil recovery, some micromodel tests were conducted using the synthesized NPs with different shapes (0.1 wt%). The results showed that spherical NPs with high uniformity were the most effective in interfacial tension (IFT) reduction (3.66 mN/m) and wettability alteration to more water wet state (47.1% reduction of contact angle) compared to other applied NPs, resulted in highest oil recovery (32%). This was attributed to more homogeneity and better dispersion of spherical NPs compared to others.

“…Preparing Functionalized Nanoparticles. Carboxylate-alumoxane nanoparticles were synthesized according to our previous study 50 and the procedure used by Callender et al 79 For producing PBMA, 7.5 g of pseudo-boehmite was mixed with deionized water (112.5 mL) and methoxyacetic acid (20 mL). For fixing the functional groups on the surface of nanoparticles, the mixture was kept under reflux for 12 h. The slurry resulting from the reflux process was centrifuged for 15 min at 5000 rpm.…”

In recent years, researchers have attempted to find some practical approaches for asphaltene adsorption and the prevention or postponement of asphaltene precipitation. Among different techniques, nanotechnology has attracted the researchers' attention to overcome the formation damage resulting from the deposition of asphaltenes. In this study, the application of two types of carboxylate-alumoxane nanoparticles (functionalized boehmite by methoxyacetic acid (BMA) and functionalized pseudo-boehmite by methoxyacetic acid (PBMA)) for asphaltene adsorption and precipitation was investigated. First, the synthesis of two functionalized nanoparticles was performed via the sol− gel method. For the assessment of the adsorption efficiency and adsorption capacity of these nanoparticles toward asphaltene adsorption, the batch adsorption experiments applying ultraviolet−visible (UV−Vis) spectroscopy were performed. The Langmuir and Freundlich isotherms were studied to describe the interaction between asphaltene molecules and carboxylate-alumoxane nanoparticles. For determining the "onset" point of asphaltene precipitation, the indirect method, which was based on the difference in the optical property of various solutions containing different concentrations of asphaltene, was utilized by applying UV−Vis spectroscopy. The isotherm models indicate that the adsorption of asphaltene on the surface of nanoparticles is better fitted to the Freundlich isotherm model compared with the Langmuir model. In the presence of PBMA (0.1 wt %), the onset point was delayed around 26, 20, and 17% in the asphaltene concentrations of 1000, 3000, and 5000 ppm, respectively, in comparison with their reference synthetic oils. On the other hand, these postponements for BMA nanoparticles (0.1 wt %) were 17%, 9%, and insignificant for the asphaltene concentrations of 1000, 3000, and 5000 ppm, respectively. The results reveal that two functionalized nanoparticles tend to adsorb asphaltene molecules and have a positive impact on the postponement of asphaltene precipitation due to molecular interactions between the surface of carboxylate-alumoxane nanoparticles and asphaltene molecules. However, PBMA nanoparticles exhibited better performance on the asphaltene adsorption and postponement of asphaltene precipitation, which is related to its smaller size, as well as higher surface area, compared with BMA nanoparticles.

“…Reservoir engineers have implemented nanoparticles (NPs) for different purposes in the petroleum industry, including the EOR. Surfactant-silica NPs solutions have drawn attention for their application in the EOR process, where they can help decrease the surfactant loss, reduce the NP dosage, increase the particle stability, and enhance the efficiency [ 42 , 43 ]. Roustaei obtained an additional 10.0% original oil in place (% OOIP) by imbibition of CTAB solution in 6.8 wt.% saline water at ambient conditions [ 44 ].…”

As a fixed reservoir rock property, pore throat size distribution (PSD) is known to affect the distribution of reservoir fluid saturation strongly. This study aims to investigate the relations between the PSD and the oil–water relative permeabilities of reservoir rock with a focus on the efficiency of surfactant–nanofluid flooding as an enhanced oil recovery (EOR) technique. For this purpose, mercury injection capillary pressure (MICP) tests were conducted on two core plugs with similar rock types (in respect to their flow zone index (FZI) values), which were selected among more than 20 core plugs, to examine the effectiveness of a surfactant–nanoparticle EOR method for reducing the amount of oil left behind after secondary core flooding experiments. Thus, interfacial tension (IFT) and contact angle measurements were carried out to determine the optimum concentrations of an anionic surfactant and silica nanoparticles (NPs) for core flooding experiments. Results of relative permeability tests showed that the PSDs could significantly affect the endpoints of the relative permeability curves, and a large amount of unswept oil could be recovered by flooding a mixture of the alpha olefin sulfonate (AOS) surfactant + silica NPs as an EOR solution. Results of core flooding tests indicated that the injection of AOS + NPs solution in tertiary mode could increase the post-water flooding oil recovery by up to 2.5% and 8.6% for the carbonate core plugs with homogeneous and heterogeneous PSDs, respectively.
