“…are hampered by the high costs of preparing and transporting fluids, especially to offshore fields. Furthermore, the discoveries of new oil fields have been scarce [1,2] and/or require more intricate technologies for the production and maximization of crude oil recovery [3].

“…The size is the key reason behind the enormous EOR potential of nanoparticles. Owing to nanoscale size and shape, NPs can improve the flooding potential through the porous media with little effect on reservoir permeability and increase recovery from thief zones [1,3,5]. With reduced size, NPs have a large surface area and, therefore, a large contact area in the swept areas [3].…”

With reduced size, NPs have a large surface area and, therefore, a large contact area in the swept areas [3]. The chemical reactivity of NPs increases in the contacted areas of a reservoir; thus, the probability of NPs altering the properties of fluids and rocks to the most favorable conditions for oil recovery also increases.…”

Nanoparticles have been proposed for enhanced oil recovery (EOR). The research has demonstrated marvelous effort to understand the mechanisms of nanoparticles-EOR. Nevertheless, gaps still exist in terms of understanding the improved fluids and fluid-rock interactions by nanoparticles, which are the key driving forces for oil mobilization. This paper investigates four types of polymer-coated silica nanoparticles as additives for water flooding oil recovery in water-wet reservoirs. A series of flooding experiments were performed with nanoparticles at 0.1 wt.% in seawater at ambient conditions. The dynamics of fluids, fluid-rock interface interactions and fluid flow behavior were characterized in order to understand oil recovery mechanisms of nanoparticles. Experimental results showed an increase in oil recovery up to 14.8%-point with nanofluid injection compared to an average of 40% of the original oil in place (OOIP) obtained from control water flood test. Moreover, the nanoparticles mobilized residual oil and incremented oil recovery up to 9.2% of the OOIP. Displacement studies show that no single mechanism could account for the EOR effect with the application of nanoparticles. Instead, the mobilization of oil seemed to occur through a combination of reduced oil/water IFT, change in the rock surface roughness and wettability to more water-wet, and microscopic flow diversion due to clogging of the pores.

The biggest challenges for E&P activities are the high viscosity of the oil, the geology of the formation, the high interfacial tensions (IFT) between fluids and the reservoir wetting conditions. Enhanced Oil Recovery (EOR) methods are applied to modify fluid-fluid and fluid-rock interactions in the reservoir, facilitating the oil displacement and, consequently, increasing the recovery factor. In this work, the use of silica nanofluids, with and without amphoteric surfactant, as EOR method to reduce the IFT and to change the wettability conditions of reservoir rock were evaluated. For experimental tests, crude oil from a reservoir in a Brazilian Pre-salt field was used as oleic phase. After data treatment, silica nanofluids (0.02 wt%) with surfactant (0.03 wt%) proved to be more effective in reducing the IFT of the system. However, the increase of silica nanoparticles (SiNPs) concentration promoted an increase in the IFT of the system, indicating a mechanical barrier effect. For nanofluids without surfactant, no significant change in IFT was observed with an increase in the concentration of SiNPs for both distilled water and brine (1,000 ppm) dispersant fluids. The significant reduction of the angle is observed for nanofluids with 0.02 wt% SiNP. Finally, the Amott test was performed in a carbonate rock sample to reaffirm the action of these chemicals in oil recovery, corroborating the potential of nanofluids to EOR applications. Thus, this work might contribute to a more rational design of nanoEOR strategies and technological innovations in carbonate reservoirs, especially those addressed to the South American Deepwater sector.
