“…In subsequent works [31], dynamic rheology measurements are presented using oscillatory tests of heavy crude mixed with nanoparticles; the results confirm the hypothesis that nanoparticles alter the internal structure of crude oil distributing the viscoelastic network formed by asphaltenes and resins in a different way.…”

“…These particles, at a determined concentration according to the characteristics of the crude oil, have the capacity to produce proven structural changes in yield stress and viscosity changes. By means of steady-state rheology measurements of light crudes and de-asphalted oil in the presence of nanoparticles, viscosity increases were obtained [31,33]. This result suggests that viscosity reduction is produced precisely by the interaction with asphaltenes.…”

“…Also, to evaluate the robustness of the proposed model, existing data of rheology of heavy and extra heavy crude oils in the presence of nanoparticles was taken from specialized literature [31][32][33]. Hence, from previous works crude oil samples SU and AK were analyzed, corresponding to a heavy and an extra heavy oil, respectively.…”

“…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.

“…formed by asphaltenes aggregates in the presence of resins which causes viscosity reduction in heavy oil [41]. Therefore, ZrO 2 nanoparticles was reported by Wei and Babadagli [42] to have a potential to be used in the recovery of heavy oil (Tables 2, 3).…”

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.

To address the poor injectivity of conventional chemicals, and the drawbacks of existing nanoparticles (NPs) in in-depth conformance control in lowpermeability reservoirs, a hydrophilic cross-linked polystyrene NPs named as CPSAs was fabricated via emulsion polymerization in this study. The reaction conditions were determined through orthogonal experiments, and the influence of each condition on the particle size of CPSAs was investigated with single factor experiments. The results showed that CPSAs with the mean diameter ranging from 73 to 95 nm could be readily produced by moderately changing the polymerization conditions, and the yield could be larger than 80%. The property evaluation results indicated that CPSAs can disperse well under reservoir conditions and was able to properly propagate to deep formation and block breakthrough regions, revealing the good injectivity and in-depth conformance control capability in low-permeability reservoirs.
