“…Data about rheological properties of tin oxide slurries dispersed with polyacrylic acid and polyvinylbutyral have been reported by dos Santos et al [18]. More recent works, as the one carried out by Ahmari et al [17], report electro rheological properties of non-Newtonian fluids (silicon oil) with the addition of SnO 2 nanoparticles finding that the apparent viscosity of suspensions increases with concentration of SnO 2 as well as electrical voltage. Habibzadeha et al [19] studied the colloidal stability of SnO 2 nanofluids prepared by dispersing nanoparticles in deionized water as base fluid, using UV-vis spectrophotometric measurements.…”

“…Nanoparticle-based systems have generally not been promising; they exhibit effects that are weaker than conventional ER fluids − . However, in 2003, a core−shell nanoparticle system, composed of barium titanyl oxalate particles (50−70 nm) coated with urea (∼10 nm) mixed with silicone oil, was found to show considerable promise.…”

It is shown, for the first time, that mixtures of sulfonated polyhedral silsesquioxane cage structures (sPOSS) and poly(dimethyl siloxane) (PDMS) with silicone oil exhibit significant electrorheological (ER) activity. At low sPOSS concentrations, less than 10 wt %, the viscosity is enhanced by approximately 100, which is comparable to the viscosity enhancements exhibited by conventional ER fluids, under the influence of comparable applied electric fields, E = 2 kV/mm. Measurements of the shear stress, sigma, dependencies on E, the conductivities, and relative permittivities reveal that the properties of these POSS/PDMS systems cannot be reconciled with theory developed to explain the behavior of conventional ER fluids.

“…in clutches, brakes and dampers. Based on previous research, it was found that the crucial factor for the ER effect is the interfacial polarization, which occurs in the frequency range of 10 2 − 10 5 Hz [6]. Application of an electrorheological fluid in subsurface engineering is still uncommon but could potentially enhance the hydrocarbon detection, enhanced oil recovery and mobility control.…”

Enhanced oil recovery (EOR) refers to the recovery of oil that is left behind in a reservoir after primary and secondary recovery methods, either due to exhaustion or no longer economical, through application of thermal, chemical or miscible gas processes. Most conventional methods are not applicable in recovering oil from reservoirs with high temperature and high pressure (HTHP) due to the degradation of the chemicals in the environment. As an alternative, electromagnetic (EM) energy has been used as a thermal method to reduce the viscosity of the oil in a reservoir which increased the production of the oil. Application of nanotechnology in EOR has also been investigated. In this study, a non-invasive method of injecting dielectric nanofluids into the oil reservoir simultaneously with electromagnetic irradiation, with the intention to create disturbance at oil-water interfaces and increase oil production was investigated. During the core displacement tests, it has been demonstrated that in the absence of EM irradiation, both ZnO and Al2O3 nanofluids recovered higher residual oil volumes in comparison with commercial surfactant sodium dodecyl sulfate (SDS). When subjected to EM irradiation, an even higher residual oil was recovered in comparison to the case when no irradiation is present. It was also demonstrated that a change in the viscosity of dielectric nanofluids when irradiated with EM wave will improve sweep efficiency and hence, gives a higher oil recovery.
