“…Except for the aforementioned core flooding tests, the glass micromodel experiment is a major means used in the study of the microscopic recovery of oils during nanofluid flooding [34,44,45,55]. By this kind of glass micromodel, the microscopic behavior of oil and nanofluid two-phase flow and fluid distribution in porous media can be continuously monitored during the experiments.…”

“…Maghzi et al [45] performed five-spot glass micromodel experiments with heavy oil and discovered that the sweep efficiency was enhanced during silica nanofluid flooding and increased with the increase of the NP concentration. Then, Li et al [34] studied three different concentrations of nanofluids as tertiary recovery agents after water flooding.…”

“…In order to understand how oil viscosity affects the wettability alteration of rock surfaces, Maghzi et al [45] conducted an experiment to study the change of contact angles when the glass surfaces coated by a SiO 2 nanofluid and heavy oil with different viscosity and found that the SiO 2 NPs also caused wettability alteration from oil-wet to water-wet regardless the viscosity of measured oil.…”

Abstract:The injected fluids in secondary processes supplement the natural energy present in the reservoir to displace oil. The recovery efficiency mainly depends on the mechanism of pressure maintenance. However, the injected fluids in tertiary or enhanced oil recovery (EOR) processes interact with the reservoir rock/oil system. Thus, EOR techniques are receiving substantial attention worldwide as the available oil resources are declining. However, some challenges, such as low sweep efficiency, high costs and potential formation damage, still hinder the further application of these EOR technologies. Current studies on nanoparticles are seen as potential solutions to most of the challenges associated with these traditional EOR techniques. This paper provides an overview of the latest studies about the use of nanoparticles to enhance oil recovery and paves the way for researchers who are interested in the integration of these progresses. The first part of this paper addresses studies about the major EOR mechanisms of nanoparticles used in the forms of nanofluids, nanoemulsions and nanocatalysts, including disjoining pressure, viscosity increase of injection fluids, preventing asphaltene precipitation, wettability alteration and interfacial tension reduction. This part is followed by a review of the most important research regarding various novel nano-assisted EOR methods where nanoparticles are used to target various existing thermal, chemical and gas methods. Finally, this review identifies the challenges and opportunities for future study regarding application of nanoparticles in EOR processes.

“…Ju and Fan (2009) reported that hydrophilic silica NP can alter the wettability of oil wet sandstone to water-wet. Maghzi et al (2012) visualized the effect of silica NP on recovery of oil-wet rocks using micro-model. They reported a substantial increase in recovery as a result of changing wettability and reducing IFT.…”

Over the past few years, increasing attention has been devoted to the applications of special engineered nanoparticles in enhancing oil recovery. Earlier studies reported the effects of these particles on wettability alteration of reservoir rock. The present study presents a new method for modifying the surface properties of silica nanoparticles to make them more effective for enhancing oil recovery purposes. Contact angle, interfacial tension measurements, and core flood experiments were performed to examine the effects of these surface-modified nanoparticles on the interfacial interactions of injected water and reservoir rock and oil sample. To improve the performance of water flooding, surface-modified nanoparticles were produced in laboratory and it was found that amine-functionalized silica nanoparticles are significantly more effective than typical nanoparticles. Experimental results revealed that both contact angle and interfacial tension decrease more in the presence of functionalized nanoparticles. These results were confirmed by performing core flood tests which showed an 18% increase in total oil recovery compared to typical nanoparticles. Therefore, amine-functionalized silica nanoparticles could be more effective than typical nanoparticles in increasing the sweep efficiency by changing the wettability of reservoir rock and reducing oil/water interfacial tension. Moreover, it was observed that there is an optimum concentration for contact angle and interfacial tension reduced by nanoparticles and in concentration more than this threshold value the interfacial tension starts to increase slightly.

Nanotechnology has found its way to petroleum engineering, it is well-accepted path in the oil and gas industry to recover more oil trapped in the reservoir. But the addition of nanoparticles to a liquid can result in the simplest flow becoming complex. To understand the working mechanism, there is a need to study the flow behaviour of these particles. This review highlights the mechanism affecting the flow of nanoparticles in porous media as it relates to enhanced oil recovery. The discussion focuses on chemical-enhanced oil recovery, a review on laboratory experiment on wettability alteration, effect of interfacial tension and the stability of emulsion and foam is discussed. The flow behaviour of nanoparticles in porous media was discussed laying emphasis on the physical aspect of the flow, the microscopic rheological behaviour and the adsorption of the nanoparticles. It was observed that nanofluids exhibit Newtonian behaviour at low shear rate and non-Newtonian behaviour at high shear rate. Gravitational and capillary forces are responsible for the shift in wettability from oil-wet to water-wet. The dominant mechanisms of foam flow process were lamellae division and bubble to multiple bubble lamellae division. In a water-wet system, the dominant mechanism of flow process and residual oil mobilization are lamellae division and emulsification, respectively. Whereas in an oil-wet system, the generation of pre-spinning continuous gas foam was the dominant mechanism. The literature review on oil displacement test and field trials indicates that nanoparticles can recover additional oil. The challenges encountered have opened new frontier for research and are highlighted herein.
