“…The functional groups and surface grafting polymerization of Fe 3 O 4 nanoparticles were confirmed by FTIR, TEM elements mapping, SEM line scan profiles, and TGA. As shown in Figure b, absorption peaks at 3405, 1617, and 565 cm –1 were the tensile vibration of the O–H bond, the out-of-plane bending vibration of the O–H bond, and the stretching vibration of the Fe–O bond, respectively, which confirmed the successful synthesis of Fe 3 O 4 nanoparticles. The absorption peaks at 2928 and 2854 cm –1 were assigned to symmetric stretching and antisymmetric stretching of −CH 3 – and −CH 2 –, and the absorption peaks at around 1520 and 1001 cm –1 were attributed to stretching vibration of N–H and Si–O, respectively, which verified that APTES was successfully grafted onto Fe 3 O 4 nanoparticles .…”

Responsive nanoparticles have attracted extensive attention because they can effectively switch between emulsification and demulsification, providing great convenience for the viscosity reduction and transportation of heavy oil. Based on the background, Fe 3 O 4 nanoparticles were prepared in this study by the coprecipitation method. N,N diethylacrylamide was grafted onto the surface of magnetic nanoparticles using reversible addition−fragmentation chain transfer polymerization to synthesize a temperature-responsive nanoparticle polymer. The morphology of it was observed by transmission electron microscopy (TEM) and scanning electron microscopy (SEM), and its chemical structure was characterized by Fourier transform infrared (FTIR) spectroscopy and thermogravimetric (TG) analysis. The results show that the viscosity reduction rate was 94.7% at an oil/water ratio of 2:8 and a concentration of nanoparticles of 0.5 wt %. Meanwhile, it exhibited a decent viscosity reduction rate of about 77% at high salinity (10,000 mg/L). More importantly, the heavy oil emulsions could effectively achieve demulsification and recycle by cooling and applying a magnetic field. After 5 cycles, the viscosity reduction rate remained at more than 90%, showing its great potential of tuning the emulsion stability of heavy oil in a sustainable way.

An essential part for crude oil extraction is flow assurance, being critical to maintain a financially sustainable flow while getting the petroleum to the surface. When not well managed, it can develop into a significant issue for the O & G industry. By heating the fluids, problems with flow assurance, including paraffin deposition, asphaltene, and methane hydrate, can be reduced. Also, as the temperature rises, a liquid’s viscosity decreases. Research focusing on the application of magnetic nanoparticles (NPs) in the oil industry is very recent. When magnetic nanofluids are exposed to an alternating magnetic field, the viscosity decreases by several orders of magnitude as a result of the fluid’s temperature rising due to a phenomenon known as magnetic hyperthermia. This work focuses on the use of magnetic NPs (9 nm) in heavy crude oil (API 19.0). The frequency and strength of the magnetic field, as well as the characteristics of the fluid and the NPs intrinsic properties all affect the heating efficiency. For all of the experimental settings in this work, the flowloop’s temperature increased, reaching a maximum of Δ T = 16.3 °C, using 1% wt NPs at the maximum available frequency of the equipment (533 kHz) and the highest field intensity for this frequency (14 kA/m), with a flow rate of 1.2 g/s. This increase in temperature causes a decrease of nearly 45% on the heavy crude oil viscosity, and if properly implemented, could substantially increase oil flow in the field during production.
