“…It is important to study the adsorption of asphaltenes and resins over nanoparticles mainly for two reasons: (i) depending on the affinity that they have for the nanoparticle, they can be eliminated from the heavy and extra-heavy crude oils and, therefore, making the remaining fraction feasible for production and transport through reduction of viscosity and increase in API gravity values without a source of external heat in the reservoir [90][91][92][93][94], and (ii) the catalytic properties of the nanoparticles could facilitate catalytic decomposition reactions resulting in lighter components in the crude oil [29].…”

“…In the crude oil matrix, the interactions between asphaltene, resins and nanoparticles can lead to viscosity reduction and is mainly driven by the disruption of the viscoelastic network [92]. This mechanism is based on the disaggregation of the viscoelastic network formed by asphaltenes and resins within the fluid, through interactions between the functional groups of nanoparticles and asphaltenes, since these interactions are stronger than those that exist between asphaltene molecules [94].…”

“…This mechanism is based on the disaggregation of the viscoelastic network formed by asphaltenes and resins within the fluid, through interactions between the functional groups of nanoparticles and asphaltenes, since these interactions are stronger than those that exist between asphaltene molecules [94]. Accordingly, several studies have demonstrated that nanoparticle addition of different chemical natures in HO and EHO generates a reduction in viscosity for low nanoparticle concentrations [92,93,110,111]. Comparative studies show that SiO 2 nanoparticles reduce the viscosity to a greater degree that Al 2 O 3 and Fe 3 O 4 nanoparticles of different sizes and degrees of surface acidity [112].…”

The increasing demand for fossil fuels and the depleting of light crude oil in the next years generates the need to exploit heavy and unconventional crude oils. To face this challenge, the oil and gas industry has chosen the implementation of new technologies capable of improving the efficiency in the enhanced recovery oil (EOR) processes. In this context, the incorporation of nanotechnology through the development of nanoparticles and nanofluids to increase the productivity of heavy and extra-heavy crude oils has taken significant importance, mainly through thermal enhanced oil recovery (TEOR) processes. The main objective of this paper is to provide an overview of nanotechnology applied to oil recovery technologies with a focus on thermal methods, elaborating on the upgrading of the heavy and extra-heavy crude oils using nanomaterials from laboratory studies to field trial proposals. In detail, the introduction section contains general information about EOR processes, their weaknesses, and strengths, as well as an overview that promotes the application of nanotechnology. Besides, this review addresses the physicochemical properties of heavy and extra-heavy crude oils in Section 2. The interaction of nanoparticles with heavy fractions such as asphaltenes and resins, as well as the variables that can influence the adsorptive phenomenon are presented in detail in Section 3. This section also includes the effects of nanoparticles on the other relevant mechanisms in TEOR methods, such as viscosity changes, wettability alteration, and interfacial tension reduction. The catalytic effect influenced by the nanoparticles in the different thermal recovery processes is described in Sections 4, 5, 6, and 7. Finally, Sections 8 and 9 involve the description of an implementation plan of nanotechnology for the steam injection process, environmental impacts, and recent trends. Additionally, the review proposes critical stages in order to obtain a successful application of nanoparticles in thermal oil recovery processes.

“…It has previously been shown that the presence of SiO 2 nanoparticles has the ability to lower the viscosity of heavy crude [11,[31][32][33]. Said viscosity reduction is produced due to the interaction between the nanoparticles and the heavy hydrocarbons present in the crude oil (asphaltenes and resins).…”

Abstract:The present work proposes for the first time a mathematical model for describing the rheological behavior of heavy and extra-heavy crude oils in the presence of nanoparticles. This model results from the combination of two existing mathematical models. The first one applies to the rheology of pseudoplastic substances, i.e., the Herschel-Bulkley model. The second one was previously developed by our research group to model the rheology of suspensions, namely the modified Pal and Rhodes model. The proposed model is applied to heavy and extra heavy crude oils in the presence of nanoparticles, considering the effects of nanoparticles concentration and surface chemical nature, temperature, and crude oil type. All the experimental data evaluated exhibited compelling goodness of fitting, and the physical parameters in the model follow correlate well with variations in viscosity. The new model is dependent of share rate and opens new possibilities for phenomenologically understanding viscosity reduction in heavy crude by adding solid nanoparticles and favoring the scale-up in enhanced oil recovery (EOR) and/or improved oil recovery (IOR) process.
