“…The viscosity was found higher at low shear rate of 1 s –1 and reduced drastically to a smaller constant value at higher shear rate (∼200 s –1 ). A similar trend was also observed by Son et al using SiO 2 nanoparticles. Figure c describes the variation in viscosity of the system with temperature for XG and XG–SNP systems at shear rate of 1 s –1 .…”

Polymer flooding based enhanced oil recovery (EOR) has been proven to be effective and successful for heavy crude oil systems due to its ability to achieve favorable mobility ratios driven by viscosity alterations. Nanoparticles have the potential to intensify favorable mobility ratios as well as various other mechanisms responsible for EOR. This work addresses the interfacial tension (IFT), emulsification, and rheological and wettability alteration characteristics of silica nanoparticle (SNP) assisted polymer flooding. The stability of the xanthan gum–SNP system was evaluated by a particle size analyzer and zeta potential method. The rheological behavior of the system in addition to IFT and the emulsification mechanism at variant temperatures were also investigated. Wettability alteration studies involved contact angle measurements for oil drops with respect to a nanoparticle saturated rock surface. SNP assisted polymer flooding enabled higher oil recovery of 20.82% at 30 °C and 18.44% at 80 °C due to IFT reduction, higher viscosity, better emulsion stability, and wettability alteration.

Chemically enhanced oil recovery methods are utilized to increase the oil recovery by improving the mobility ratio, altering the wettability, and/or lowering the interfacial tension between water and oil. Surfactants and polymers have been used for this purpose for the last few decades. Recently, nanoparticles have attracted the attention due to their unique properties. A large number of nanoparticles have been investigated for enhanced oil recovery applications either alone or in combination with surfactants and/or polymers. This review discusses the various types of nanoparticles that have been utilized in enhanced oil recovery. The review highlights the impact of nanoparticles on wettability alteration, interfacial tension, and rheology. The review also covers the factors affecting the oil recovery using nanoparticles and current challenges in field implementation.

“…They appear almost everywhere and in diverse products like detergents, pharmaceuticals, wettability modifiers, drilling muds, motor oils, and even foods. Presence of nanoparticles, which is unavoidable in many industrial activities such as chemical enhanced oil recovery (EOR) processes, can considerably affect the behavior of surfactants 1 – 4 . The complex system of surfactant-nanoparticle functions as a novel surface-modifying agent and can be used for stabilizing disperse systems such as foams and emulsions 5 – 8 .…”

Hydrophilic silica nanoparticles alone are not surface active. They, however, develop a strong electrostatic interaction with ionic surfactants and consequently affect their surface behavior. We report the interfacial behavior of n-heptane/anionic-surfactant-solutions in the presence of hydrophilic silica nanoparticles. The surfactants are sodium dodecyl sulfate (SDS) and dodecyl benzene sulfonic acid (DBSA), and the diameters of the used particles are 9 and 30 nm. Using experimental tensiometry, we show that nanoparticles retain their non-surface-active nature in the presence of surfactants and the surface activity of surfactant directly increases with the concentration of nanoparticles. This fact was attributed to the electrostatic repulsive interaction between the negatively charged nanoparticles and the anionic surfactant molecules. The role of electrostatic repulsion on increasing surface activity of the surfactant has been discussed. Further investigations have been performed for screening the double layer charge of the nanoparticles in the presence of salt. Moreover, the hydrolysis of SDS molecules in the presence of silica nanoparticles and the interaction of nanoparticles with SDS inherent impurities have been studied. According to our experimental observations, silica nanoparticles alleviate the effects of dodecanol, formed by SDS hydrolysis, on the interfacial properties of SDS solution.
