“…The application of nanoparticles in the petroleum industry is not new. 1 , 22 − 25 Researchers are continuously trying to modify even surfactant polymer flooding by the addition of nanoparticles in the chemical slug that could reduce the adsorption of the surfactant as well as the interfacial tension (IFT), which could lead to the recovery of more oil from mature fields. 6 , 26 − 28 Nanoparticles are of great interest to scientists because of their small size and larger surface area.…”

Surfactant polymer flooding is one of the most common chemical enhanced oil recovery techniques, which improves not only the microscopic displacement of the fluid through the formation of the emulsion but also the volumetric sweep efficiency of the fluid by altering the viscosity of the displacing fluid. However, one constraint of surfactant flooding is the loss of the surfactant by adsorption onto the reservoir rock surface. Hence, in this study, an attempt has been made to reduce the adsorption of the surfactant on the rock surface using novel colloidal silica nanoparticles (CSNs). CSNs were used as an additive to improve the performance of the conventional surfactant polymer flooding. The reduction in adsorption was observed in both the presence and absence of a polymer. The presence of a polymer also reduced the adsorption of the surfactant. Addition of 25 vol % CSNs effectively reduced the adsorption of up to 61% in the absence of a polymer, which increased to 64% upon the introduction of 1000 ppm polymer in the solution at 2500 ppm of the surfactant concentration at 25 °C. The adsorption of surfactant was also monitored with time, and it was found to be increasing with respect to time. The adsorption of surfactant increased from 1.292 mg/g after 0.5 days to 4.179 mg/g after 4 days at 2500 ppm of surfactant concentration at 25 °C. The viscosity, surface tension, and wettability studies were also conducted on the chemical slug used for flooding. The addition of CSNs effectively reduced the surface tension as well as shifted the wettability toward water-wet at 25 °C. Sand pack flooding experiments were performed at 60 °C to access the potential of CSNs in oil recovery, and it was found that the addition of 25 vol % CSNs in the conventional surfactant polymer chemical slug aided in the additional oil recovery up to 5% as compared to that of the conventional surfactant polymer slug.

“…In order to meet these requirements, the NPs should have excellent dispersion stability under actual reservoir conditions, and the particle size will not increase significantly before reaching the deep target area.

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.

With the growing demand for energy supply and the natural decline of oil reservoirs, the development of new enhanced oil recovery (EOR) techniques become more and more critical. Polymer flooding EOR is one of the most successful chemical EOR methods but suffers many drawbacks at high temperatures and high salinity (HT‐HS) conditions. Superparamagnetic nanoparticles (NPs) have been recently investigated for subsurface applications, including in EOR, due to their unique physicochemical properties. Their applicability under harsh reservoir conditions, however, is yet to be examined. In this work, a novel approach is developed to synthesize superparamagnetic Fe3O4 (NPs) with unique surface functionalization (SMag‐NPs) and to form stable polyacrylamide (PAM) dispersions (SMag‐NPs‐PAM). Both stability and core flooding experiment results demonstrate the promising future of the new dispersion. The SMag‐NPs‐PAM dispersion is not only stable at HT‐HS conditions, but also show excellent EOR capability at HT‐HS by recovering, 61.72% of the initial oil quantity, which is significantly higher than those from conventinal NPs‐PAM disperison and pure PAM fluid. These findings show the promising application potential of SMag‐NPs‐PAM for improving oil recovery in challenging HT‐HS reservoir conditions.
