High viscosity of oil related to high interfacial tension between oil and brine water. To reduce this high interfacial tension, we proposed new method by using nanofluid injection with the aid of electromagnetic (EM) wave. Dielectric nanofluids will polarize at low frequency of 1 kHz. Dielectric nanoparticles of ZnO,CoO and AbO, were synthesized by using sol gel method and was characterize using X-Ray Diffractometer (XRD), Field Emission Scanning Electron Microscope (FESEM), Energy Dispersive X-Ray (EDX) and RAMAN Spectroscopy.ZnO has lower atomic deviation of 3.08%, small crytallite size of 12.27 nm,and have high dielectric constant of 3xE6.Nanopowder were mixed with stabilizer, Sodium Dodecyl Sulphate (SDS) before injected into the column. The nanofluid mixed with I% SDS stay suspended for a month duration. 22 em lenght of Polyvinyl Chloride (PVC) column filled with 535.81 mD glass beads was flooded with 20 kppm ofbrine water and with crude oil viscosity of 16.31 cpWater flooding performed before continue with nanofluids injection. From oil recovery experiment, ZnO yields the highest recovery factor which is 31 % compared to CoO and Ab03 which only have recovery factor of 12.5% and 10 % respectively.This is a new contribution towards the industry as the role of EM wave to activate the ZnO is significant.
