“…Nanoparticle surface wettability (i.e., hydrophobicity and hydrophilicity) is the most critical factor that influences the arrangement of nanoparticles at the oil–water interface. , The electrolyte concentration influences the wettabilities of the nanoparticles , and stabilities of the surfactants . The type of rock in the reservoir impacts the mobility of the surfactant and the selection of surfactants for IFT reduction .…”

Nanoparticles have been used in conventional enhanced oil recovery to improve the oil recovery efficiency. In this review, we analyzed the roles of nanoparticles in improving enhanced oil recovery. We focused on elucidating the fundamental mechanisms that regulate nanoparticle-induced enhanced oil recovery, including surface wettability alteration, interfacial tension reduction, mobility ratio increase, emulsion stabilization, and foam stabilization. We also discussed factors that control the success of nanoparticle-induced enhanced recovery. Finally, we outlined the current challenges and future research directions with respect to the applications of nanoparticles in enhanced oil recovery.

“…Based on the available literature, it appears that the primary mechanisms associated with oil production using Si-NF include, primarily, (1) IFT reduction [14,31,32], (2) wettability alteration [14,[33][34][35], (3) the prevention of asphaltene precipitation [36,37], and (4) porosity impairment [30,38,39]. However, most of the published works fail to address the contribution of the formation salinity.…”

The underlying effect of preflush salinity and silica nanofluid (Si-NF) on oil production is examined. The influence of salinity on the stability of Si-NFs is studied. A series of sand-pack floodings evaluating oil production was conducted at different concentrations of preflush salinity (0 to 4 wt.%), followed by the injection of a Si-NF (0.5 wt.%) at the trail of which postflush water was injected. The effluent water and solids were collected and analyzed using X-ray fluorescence (XRF). Interfacial tension (IFT) and contact angle measurements were conducted on the Si-NF in the presence of salinity to confirm the effect. The Si-NF became unstable and formed precipitate in the presence of salinity. The sand-pack flooding showed that when the preflush salinity was increased, the displacement efficiency (ED) using the Si-NF and postflush injection was increased (ED = 44%). The XRF of the precipitated effluent revealed that the preflush salinity and Si-NF caused mineral leaching, which triggered pore clogging. The IFT value reduced from 13.3 to 8.2 mN/m, and the wettability was altered to be more strongly water-wet when the salinity increased. The primary mechanisms of oil recovery using the Si-NF after preflush salinity is attributed mainly to the clogging mechanism. This clogging helps block the high-perm area, shift the fluid flow to the oil-trapped zone, and free the oil out. Other contribution mechanisms are IFT reduction and wettability alteration.
