The study intend to search new ways to enhance oil recovery from fields of Colombia and neighboring countries of the Andean Basin. A sandpack porous medium saturated with paraffinic oil will be used to simulate a sandstone reservoir type and the oil will be move throw out by the combined application of a nanofluids water base compound dispersed Fe₂O₃ nanoparticles at various concentrations and magnetic fields. The proposed methodology first will characterize the porous medium, fluids and the nanoparticles (NMR, XRD, etc.), then the porous medium oil with water and then with nanofluids and magnetic fields will move. The effluent collected will be analyzed for their composition and viscosity study after combined treatment and then study the mathematical relationship between the effect of treatment times, nanoparticle concentration and intensity of magnetic field applied. The validation will be based on results provided by Craig (1982) from secondary oil recovery by immiscible displacement and compare with water and surfactant displacement in similar porous mediums. It will be expected that the results show that exists a relationship between the increase in enhanced oil recovery from this proposed technique. The conclusions shall show the effect of the time of magnetic field applied magnetic field intensity and concentration of nanoparticles on oil viscosity to enhance its sweep and improve the recovery thereof compared to a conventional water displacement process.
