“…The precipitation of polymers is thought to be due to the divalent cations in aqueous solution (e.g. Mg 2+ , Ca 2+ ) and high temperature [26,32]. Consequently, the desired repulsion forces between the NPs in the solution vanished.…”

“…This, in turn, makes it difficult to adequately grasp the oil recovery mechanisms of silica nanoparticles. Aside from i) IFT reduction and wettability alteration, which are the two most suggested mechanisms [11,15,16,18], NPs improve oil recovery by ii) structural disjoining pressure [26], iii) formation of emulsions [19][20][21], and iv) log-jamming effect [5-7, 13, 22-24]. In some circumstances, more than one mechanism is associated with oil recovery.…”

Extraction of oil trapped after primary and secondary oil production stages still poses many challenges in the oil industry. Therefore, innovative enhanced oil recovery (EOR) technologies are required to run the production more economically. Recent advances suggest renewed application of surfacefunctionalized nanoparticles (NPs) for oil recovery due to improved stability and solubility, stabilization of emulsions, and low retention on porous media. The improved surface properties make the NPs more appropriate to improve microscopic sweep efficiency of water flood compared to bare nanoparticles, especially in challenging reservoirs. However, the EOR mechanisms of NPs are not well understood. This work evaluates the effect of four types of polymer-functionalized silica NPs as additives to the injection water for EOR. The NPs were examined as tertiary recovery agents in water-wet Berea sandstone rocks at 60 °C. The NPs were diluted to 0.1 wt. % in seawater before injection. Crude oil was obtained from North Sea field. The transport of NPs though porous media, as well as nanoparticles interactions with the rock system, were investigated to reveal possible EOR mechanisms. The experimental results showed that functionalized-silica NPs can effectively increase oil recovery in water-flooded reservoirs. The incremental oil recovery was up to 14% of original oil in place (OOIP). Displacement studies suggested that oil recovery was affected by both interfacial tension reduction and wettability modification, however, the microscopic flow diversion due to pore plugging (log-jamming) and the formation of nanoparticle-stabilized emulsions were likely the relevant explanations for the mobilization of residual oil.

“…This attribute of nanoemulsion, has had a huge impact on EOR mechanism as residual oil is recovered from the reservoir. Small drop size of nanoemulsion which is usually smaller than the pore throat in gravel-pack and reservoir rock can result in good injectivity and penetration without filtration [72]. This can prevent the issue of gravitydriven separation due to the density difference of the two phases.…”

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.
