Electromagnetic nanoparticle-assisted oil recovery: Numerical simulation and practical implications

• The performance of hybrid nanomaterials (BaTiO 3 /MnO 2 and BaTiO 3 /CoO) in reducing IFT and altering wettability due to combined dielectric and magnetic properties. • The use of ferrite magnetic nanoparticles (FMNPs) combined with electromagnetic fields (EMF) to significantly enhance oil recovery processes. • FMNPs respond to EMFs by generating localized heating, reducing crude oil viscosity and interfacial tension, thus facilitating improved fluid flow and extraction. • Provided valuable insights into optimizing nanoparticle concentration, EMF frequency, and field intensity for maximum efficiency in oil recovery. Investigating cutting-edge technology for enhanced oil recovery (EOR) is crucial for prolonging the productive lifetime of oil reservoirs. This work presents a new use of ferrite magnetic nanoparticles (FMNPs) combined with the propagation of electromagnetic fields (EMF) to enhance the process of oil recovery. 3-D finite element methods (FEM) were used to create a model and simulate the interaction between FMNPs and EMFs in the porous medium of an oil reservoir. Interfacial Tension (IFT) and viscosity tests were conducted to validate the simulation, and the morphology of the Ferrite magnetics nanoparticles to show the sizes and Energy Dispersive X-ray (EDX). To improve flow and extraction, the FMNPS are designed to react to electromagnetic fields, which cause localised heating and a decrease in the viscosity of crude oil. A thorough examination of the distribution of temperatures, fluid dynamics, and interactions with magnetic fields may be obtained by the FEM models. The results of these simulations provide important information for improving recovery efficiency by adjusting the concentration of nanoparticles, the frequency of the EMF, and the strength of the field. This study shows that BaTiO 3 , Mno 2 , and CoO nanoparticles significantly influence the dielectric, permeability, and polarisation properties of reservoir sandstone. Enhanced nanoparticle dispersion improves electrokinetic effects, oil mobilization, and wettability alteration. Electromagnetic simulations confirm strong dielectric responses, supporting improved oil recovery and advanced reservoir characterization techniques.
