“…IFT of the deionized water and crude oil was measured as 35 mN/m; while, the optimum concentration provides a 17 mN/m reduction in IFT. In other words, the nanofluid prepared by using this novel NC is able to reduce the IFT by 48.5% [ 76 , 77 , 78 , 79 , 80 , 81 ]. Figure 14 illustrates the measurements of the dynamic IFTs of nanofluids over a period of steps over time (The final and fixed values of IFTs are measured from dynamic values.…”

In this paper, synthesis and characterization of a novel CeO2/nanoclay nanocomposite (NC) and its effects on IFT reduction and wettability alteration is reported in the literature for the first time. The NC was characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), energy-dispersive X-ray spectroscopy (EDS), and EDS MAP. The surface morphology, crystalline phases, and functional groups of the novel NC were investigated. Nanofluids with different concentrations of 100, 250, 500, 1000, 1500, and 2000 ppm were prepared and used as dispersants in porous media. The stability, pH, conductivity, IFT, and wettability alternation characteristics of the prepared nanofluids were examined to find out the optimum concentration for the selected carbonate and sandstone reservoir rocks. Conductivity and zeta potential measurements showed that a nanofluid with concentration of 500 ppm can reduce the IFT from 35 mN/m to 17 mN/m (48.5% reduction) and alter the contact angle of the tested carbonate and sandstone reservoir rock samples from 139° to 53° (38% improvement in wettability alteration) and 123° to 90° (27% improvement in wettability alteration), respectively. A cubic fluorite structure was identified for CeO2 using the standard XRD data. FESEM revealed that the surface morphology of the NC has a layer sheet morphology of CeO2/SiO2 nanocomposite and the particle sizes are approximately 20 to 26 nm. TGA analysis results shows that the novel NC has a high stability at 90 °C which is a typical upper bound temperature in petroleum reservoirs. Zeta potential peaks at concentration of 500 ppm which is a sign of stabilty of the nanofluid. The results of this study can be used in design of optimum yet effective EOR schemes for both carbobate and sandstone petroleum reservoirs.

“…The increasing energy demand for domestic and industrial uses led to the application of enhanced oil recovery (EOR) to extract residual oil after primary and secondary methods (Afolabi and Yusuf 2019;Hendraningrat and Torsaeter 2016;Soleimani et al 2016a, b;Hamza et al 2017a, b). In most EOR technologies, such as surfactant flooding, polymer-surfactant flooding and foam flooding, surfactants play unprecedented roles that include reduction in interfacial tension and sometimes in gas mobility control (Moradi et al 2019;Hanamertani et al 2018;Dang et al 2017;Kamal et al 2017;Soleimani et al 2015). A major technical challenge during chemical and gas flooding that received widespread interests is the effect of viscous fingering and early gas breakthrough (Jia et al 2017;Xu et al 2016;Hendraningrat and Zhang 2015).…”

In this study, an industrial-based surfactant known as MFomax surfactant has been modified with unfunctionalized and silanefunctionalized silica nanoparticles (NPs) to select the high viscous nano-fluid (NF) for generation of in situ foam to assess the differential pressure buildup (∆p) behavior in the porous media. Different weight concentrations of NPs and MFomax from 0.1 to 0.5% were studied using Design Expert Software to generate full matrix design of NF formulations. The viscosity data were analyzed with the aid of response surface analytical tool to investigate the response of NPs loading on the NF viscosity for optimization. The microstructural properties of the NFs were characterized using spectroscopic equipment. Subsequently, the high viscous NF was selected to generate in situ foam in comparison with the precursor MFomax foam for ∆p buildup assessment at 110 °C and 2023 psi in the native reservoir core. Results have shown that both the silica NPs could significantly improve the MFomax viscosity; however, the silane-functionalized silica NPs have more effect to improve the viscosity and other microstructural properties than the unfunctionalized NPs, and thus, they were selected for further experimental studies. The coreflood ∆p buildup assessment shows that NF foam built more ∆p having average value of 46 psi against 25 psi observed in the case of the precursor MFomax foam. Thus, this study demonstrates that functionalized silica NPs could improve the MFomax viscosity and eventually generates high ∆p buildup at high-temperature high-pressure conditions.

“…The general mechanism of IFT reduction by nanomaterials has been clarified thoroughly by Li et al and Dahle et al, who explained that nanocomposites create a layer-like structure at the interface of crude oil and the probe fluid. This structure acts as a mediator and leads to lower IFTs between the said immiscible fluids, just as surfactants reduce IFT . Individual nanoparticles of TiO 2 and CuO show the effects of synergistic integration in reducing IFT as well as of the addition of a polymer coating that activates an extra cooperative effect among other agents to yield an effect superior to their individual effects.…”

CuO/TiO₂/PAM as a Novel Introduced Hybrid Agent for Water—Oil Interfacial Tension and Wettability Optimization in Chemical Enhanced Oil Recovery

The main target of this research is the development of a novel nanocomposite consisting of copper(II) and titanium oxide nanoparticles and polyacrylamide (PAM) polymer for use as a hybrid agent beside other chemical factors in enhanced oil recovery (EOR) processes. The optimization of interfacial tension (IFT) and wettability alteration, the most important issues in improving oil recovery, orient both the selection of the aforementioned materials and the presentation of a hybrid agent in chemical enhanced oil recovery (CEOR). This work focuses on the development of a simple, economical, and ecofriendly method for green synthesis of the CuO/TiO2/PAM nanocomposite to create a nanofluid that alters the oil-wetting state of carbonate and sandstone reservoirs into a water-wetting state, as well as reduces the water–oil IFT simultaneously. A green Cassytha filiformis L. fruit extract was used to synthesize the nanocomposite. The product underwent characterization tests, including the use of field-emission scanning electron microscope (FESEM), energy dispersive X-ray spectroscopy (EDS) and EDS Map, X-ray diffraction (XRD), and thermogravimetric analysis, to achieve better analytical characterization. Nanofluids at various concentrations ranging from 100–1500 ppm were formulated, and their stabilities were studied through zeta potential measurements. The results of zeta potential tests confirmed the stability of the developed nanocomposite in water-based solutions. The IFTs of the developed nanofluids and the crude oil of the Sarvestan oil field (a carbonate reservoir located in the south of Iran) were then measured. In addition, wettability alteration tests were conducted for both carbonate and sandstone rocks in order to observe all rock type dependency of mechanisms. The results showed that the novel synthesized nanocomposite reduced water–oil IFT by about 46% at the low concentration of 200 ppm. Optimization of wettability alteration is the main reason to use nanosized materials in a CEOR approach. Our investigation showed that, at the optimum nanofluid concentration of 200 ppm, a 90% wettability alteration (from 151° to 14.7°) in the water-wetting state of carbonate rocks is achieved. For sandstone rocks, the nanocomposite showed a 91% optimization of wettability alteration (from 135.25° to 11.75°) at higher concentrations, with a concentration of 1500 ppm being the optimum.
