Abstract. This paper describes the synthesis of cobalt ferrite (CoFe 2 O 4 ) nanoparticles and their application in enhanced oil recovery. Cobalt ferrite (CoFe 2 O 4 ) nanoparticles were used as ferrite magnetic feeders with antenna to improve the magnetic field strength and cobalt ferrite nanofluid to improve oil recovery. Cobalt ferrite (CoFe 2 O 4 ) nanoparticles were synthesized by sol-gel method. These nanoparticles were then characterized by using X-ray diffractometer (XRD) and Field Emission Scanning Electron Microscope (FESEM). Cobalt ferrite nanoparticles annealed at 600 o C, the particle size is 51.17nm and 26nm as determined by XRD and FESEM, respectively while for the sample annealed at 800 o C, the particle size is 62nm as determined by XRD and 60 nm as determined by FESEM. Magnetic measurement results show that initial permeability of cobalt ferrite powder increased and relative loss factor decreased at high frequency. In order to improve the oil recovery, nanoparticles were used in two different experiments. In the first experiment, nanoparticles were used as magnetic feeders with an antenna to improve the magnetic field strength. In the second experiment, nanoparticles were used as nanofluids. Results show that the antenna with magnetic feeders increases the magnetic field strength by 0.94% as compared to antenna without magnetic feeders in the water, and by 5.90% in the air. Magnitude versus offset (MVO) study of antenna with magnetic feeders shows an increase in magnetic field strength of 275% as compared to antenna without magnetic feeders. It is found that antenna with magnetic feeders was able to recover 29.50% and 20.82% of original oil in place (OOIP) in core rock samples A-1 and A-2 respectively. The use of cobalt ferrite nanoparticles as a nanofluid with electromagnetic waves yielded a higher recovery of residual oil in place (ROIP) which is 31.58% as compared to 8.70% when it was used as nanofluid alone. It is investigated that due to absorption of electromagnetic waves by cobalt ferrite nanoparticles the oil viscosity reduces which increase the oil recovery. It can be concluded that the synthesised cobalt ferrite (CoFe 2 O 4 ) nanoparticles can be potentially used for enhanced oil recovery in future.

“…Receivers are placed on the sea floor to detect direct, reflected and guided waves from the seabed. Guided waves from the deep target have very low magnetic field strength [1][2][3][4][5][6][7][8][9][10][11][12][13], whereas oil and gas industry require strong electromagnetic signals with low signal to noise ratio for the detection of the deep targets. Nanoferrites have been used in many practical and technological applications, such as, magnetic devices in electronics, optical and microwave devices, memory storage, waveguides, isolators, permanent magnets, inductors, circulators phase shifters, relays, sensors and antennas etc.…”

Electromagnetic signals in deep reservoir are very weak so that it is difficult to predict about the presence of hydrocarbon in seabed logging (SBL) environment. In the present work, Mn 0.8 Zn 0.2 Fe 2 O 4 nanoferrites were prepared by a sol-gel technique at different sintering temperatures of 450 1C, 650 1C and 850 1C to increase the strength of electromagnetic (EM) antenna. XRD, FESEM, Raman spectroscopy and HRTEM were used to analyze the phase, surface morphology and size of the nanoferrites. Magnetic properties of the nanoferrites were also measured using an impedance network analyzer. However, nanoferrites sintered at 850 1C with initial permeability of 200 and Q factor of 50 were used as magnetic feeders with the EM antenna. Lab scale experiments were performed to investigate the effect of magnetic field strength in scale tank. SPSS and MATLAB softwares were also used to confirm the oil presence in scale tank. It was observed that the magnitude of the EM waves for the antenna was increased up to 233%. Finally, the correlation values also show 208% increase in the magnetic field strength with the presence of the oil. Therefore, antenna with Mn 0.8 Zn 0.2 Fe 2 O 4 nanoferrites based magnetic feeders can be used for deep water and deep target hydrocarbon exploration.

Marine CSEM is a new technique for detection of deep target hydrocarbons. Aluminum EM antenna was developed, and nanostructured NiZn magnetic feeders were used to increase the field strength from EM antenna for deep hydrocarbons. The doping of Ni2+ was aimed at the optimization of initial permeability and magnetic losses. Ni0.5+xZn0.5‐xFe2O4 (x = 0.3) samples sintered at 950°C presented highest initial permeability (106.23) and low magnetic loss (0.0002) as compared to other samples. Due to better magnetic properties, Ni0.5+xZn0.5‐xFe2O4 (x = 0.3) samples were used as magnetic feeders for EM antenna. Magnitude of EM waves from the antenna increased up to 186%.
