The polarization effect on reservoir sandstone under an electric double layer is one of the major research interests. The nanoparticles agglomeration such as graphene nanofluid due to poor dispersion in reservoir zone can be a major challenge that can lead to low reservoir permeability are well elucidated. This study investigated the influence of graphene nanofluid on the ionic polarization under an electric double layer in reservoir sandstone. Saturated Berea sandstone was used to investigate the interaction of ionic species on reservoir sandstone with the aid of Field-emission microscopy (FESEM), Energy dispersive X-ray mapping (EDX), Fourier Transform Infrared Spectroscopy (FTIR), Raman spectral analysis, and Core flooding experiment. This research gives information on the adsorption of ions within an electric double layer ...

Zinc Oxide (ZnO) and Bismuth ferrite BiFeO 3 (BFO) nanoparticles were synthesized via facile sol-gel method followed by nanofluid preparation. Sandstone samples were saturated with brine and nanofluids for 48 h. Electromagnetic properties of the saturated sandstones were measured experimentally using the vector network analyzer, and the scattering parameters of the samples were studied numerically by finite element method. BFO displayed higher permeability value of 1.52 and 1.30, as well as superior dielectric permittivity value 11.55 and 6.59 for real and imaginary parts, respectively. In addition, the sandstone saturated with BFO showed an impressive reflection loss (RL) value of −9.77 dB at high frequency. Conclusively, BiFeO 3 nanofluids showed the best potential to enhance oil recovery which can be accredited to the superior electromagnetic properties of BFO.

The images of scanning electron microscopy (SEM) verify full graphene exfoliation at 1000 C. Inclusion graphene develops crystallinity; increases the local order of lattice and thermal stability of LDPE/graphene nanocompounds. The consistent distributions and further inclusion of graphene caused the great heat breakdown strength, increasing heat breakdown activation energy and a superior melting point (Tm) for LDPE nanocompounds. Percolation occurs with the graphene incorporation of 0.5 wt%. The complex viscosity test showed Newtonian behavior for LDPE at a very low frequency. But, graphene inclusion to LDPE changed the viscosity performance from liquid-like to solid-like which caused a decrease in the melt flow rate (MFR) values for all LDPE/graphene nanocompounds.

The reflection and transmission coefficients of PVDF/LIG were measured using rectangular waveguide in conjunction with a microwave vector network analyzer (VNA) at X-band frequencies (8 GHz - 12 GHz). In this study, the distribution of electric field intensity of PVDF/ LIG which was loaded in rectangular waveguide was simulated based on Finite Element Method (FEM) formulation to show the essential differences of intensity of emitted electrical field. The computations of reflection and transmission coefficients of PVDF/ LIG were determined by using implementation FEM modeling rectangular waveguide. The FEM results were compared with the experimental achievement results using the rectangular waveguide. An excellent agreement between measured and simulated results was obtained based on the values of mean relative errors.

Porous activated carbon from agricultural wastes has piqued the interest of MA researchers due to their distinct properties such as good specific surface area, high dielectric loss, good electrical conductivity, and low density. Herein banana peel activated carbon was prepared by activating banana peel precursor with KOH and carbonizing at different temperatures. The difference in the porous structure with varying carbonization temperature was visible in the FESEM image, validated by BET analysis. The Banana Peel Activated carbon samples exhibited good microwave absorption performance, with BP-AC700 displaying a minimum Reflection Loss (RL) of −40.62 dB at 10.72 GHz & 3.0 mm thickness. In addition, the obtained effective absorption bandwidth of 3.5 GHz span...

In the case of offshore environments, these constraints can be avoided if a horizontal antenna is towed close to the seabed, which maximises the electromagnetic energy transferred from the overburden to the reservoir and nanofluids in the reservoir. In this research, a new enhanced antenna is used with iron oxide (Fe2O3) and zinc oxide (ZnO) nanofluids for oil recovery applications at the laboratory scale. In the antenna study, it was observed that the curve antenna with magnetic feeders gave a 1978% increase in the magnetic field signal strength compared to the case without magnetic feeders. The curve antenna with magnetic feeders produced a 473% increase in the electric field signal strength compared to the case without magnetic feeders. Iron oxide (Fe2O3) nanoparticles were prepared by the sol-gel method. The iron oxide (Fe2O3) nano...

Magnetic nanoparticles which are activated by a magnetic field are anticipated to have the ability to travel far into the oil reservoir and assist in the displacement of the trapped oil. In this work, magnetic Fe2O3-Al2O3 nanocomposite was synthesized and characterized for its morphological, structural and magnetic properties. At an annealing temperature of 900°C, this nanomaterial starts to exhibit magnetization as the composite structure crystallizes to the stable Fe2O3 and Al2O3. Subsequently, dispersion of the 0.01 wt% Fe2O3-Al2O3 nanocomposite in distilled water was used for displacement tests to validate its feasibility to be applied in EOR. In the displacement test, the effect of electromagnetic waves on the magnetization of Fe2O3-A...

The annealing temperature was fixed at 600 ºC. The impact of pH on the particle size was investigated. Based on the results from the Thermogravimetric Analysis (TGA), three different pH for the precursor which is 3.0, 5.0 and 1.01 were chosen followed by the characterization of the ZnO nanoparticle by using Powder X-Ray Diffraction (PXRD), Transmission Electron Microscopy (TEM) and Field Emission Scanning Electron Microscopy (FESEM). Results showed that the crystallite size estimated from PXRD increased with the pH value which was hexagonal structure for ZnO. TEM further revealed the same tendency which the Zn NPs size also increased with the alkalinity of the precursor.

Two catalyst were taken into consideration namely carbon nanotubes (CNTs) and hematite adjacent with CNTs. The simulation based study of the adsorption of hydrogen and nitrogen with reference to change in number of electron and band-gap of carbon nano tubes and hematite mixed with carbon
nanotubes was not reported in literature. For this reason carbon nanotubes band gap for different chirality and number of
walls was calculated through simulation. After that simulation for number of electrons, band gap and average total energy
of CNTs alone and a mixture hematite with CNTs was performed before and after adsorption of hydrogen and nitrogen.
From simulation the number of electrons were found to be doubled for hematite mixed with CNTs and average total energy was also increased as compared to similar parameter for CNTs without hematite. In conclusion the hematite with carbon nanotubes is preferred candidate for ammonia synthesis using magnetic induction method. Ammonia synthesis was done using MIM. Ammonia yield was quantified by Kjaldal method.

In this method, an ultralow frequency electromagnetic (EM) wave is emitted by an electric straight dipole which moves parallel to the seabed.
Following Maxwell's equations, reflected and refracted waves from different layers are recorded by receiver line which is
laying on the sea floor to define the contrast between amplitude and phase of responding waves of bearing oil reservoir and
surrounding host rocks. The main concern of the current work is to study behavior of airwave, which is propagated wave in the seawater area, guided by sea surface and refracted back to the receiver line, and its impact on tangential and normal components of received electric field amplitude. Will be reported that the most significant part of tangential component is airwave, while it does not affect normal component of received electric field, remarkably.

Hematite nanowires were obtained by the oxidation of an iron wire at a temperature of 650°C and ambient pressure in the presence of N 2 and O 2 gases. Cupric oxide nanowires were obtained by the same method at 700°C, using a copper wire. The X-ray diffraction results show the formation of rhombohedral structure of α-Fe 2 O 3 and monoclinic phase of CuO. FE-SEM results reveal the formation of nanowires with dimensions ranging between 5-15 µm and 4-12 µm in length and a diametere ranging between 50-150 nm and 50-250 nm for α-Fe 2 O 3 and CuO respectively. The VSM results show that the saturation magnetization values for hematite and cupric oxide were 132.8700 and 0.0124 emu/g, respectively. The nanowires were used as catalyst for green urea synthesis in the presence of an oscillating and a static magnetic fields. The use of nanocatalyst with high saturation magnetization gives a higher yield of urea due to the increase in the singlet to triplet conversion. The highest yield of urea 11243 ppm was achieved by applying an oscillating magnetic field of frequency 0.5 MHz and using α-Fe 2 O 3 nanowires as nanocatalyst. (B. Alqasem).

SmCo thin films show tremendous potential for use as permanent magnetic films on account of their high anisotropy fields, moderately high saturation magnetization and high curie temperature. In the present research, SmCo thin films have been deposited on single crystal Si(1 0 0) substrates using pulsed laser deposition technique. The films were deposited at a fixed substrate temperature of 400 • C by varying the number of pulses, in order to get thin films of different thicknesses. Effect of laser pulses on the crystal structure evolution, composition of the deposited material, film thicknesses and hence the magnetic properties have been investigated. X-ray diffraction analysis was performed in order to determine the crystal structure of the deposited films. The compositional analysis was performed by using energy dispersive X-ray spectroscopy. A slight variation in the Sm and Co contents was observed in the thin films grown by varying the laser shots. The microstructural information of the thin films was obtained by using a scanning electron microscope. The magnetic and electrical parameters were investigated by using vibrating sample magnetometer and two point probe respectively. The results show hard magnetic and conducting nature of all deposited thin films except sample 1 due to

In this study, nanofluid injection was proven to be potential tool for increasing oil recovery. Experiments were conducted to examine the impact of multi wall carbon nanotubes (MWCNTs) concentration on recovery efficiency and fluid mobility. BET analysis was used to investigate the surface area of MWCNTs. High Resolution Transmission Electron Microscope (HRTEM) was used to provide morphological description, and to evaluate the physio-chemical surface properties of the MWCNTs based on contact angle. Nanofluids of three different concentrations (0.01, 0.05 and 0.10 wt. %) were prepared from the MWCNTs. A water flooding experiment was then carried out to assess the impact of the nanofluid. From the results of, the MWCNTs fluid was found to be a good EOR agent. The highest recovery efficiency 31.8% of residual oil in place (ROIP) was achieved with the nanofluid of 0.05wt.% MWCNTs concentration. However, by observing the values of mobility reduction factor (MRF) used to investigate the fluid behaviour, it can be concluded that the behaviour of hydrophobic MWCNTs in water fluid is unpredictable.

Research on application of nanoparticles either on its own or coupled with other stimulating agents has been growing enormously and some of them have shown a promising future. In high temperature and high pressure reservoirs, thermal degradation will cause failure to the conventional chemicals. In this work, temperature-stable YIG magnetic nanoparticles with an electromagnetic wave has been proposed as a new candidate for reservoir stimulating agent. The purpose of nanoparticle injection is to increase the sweep efficiency in the reservoir by increasing the viscosity of displacing fluid. In this research, Yttrium iron garnet (YIG) nanoparticles have been injected into a waterflooded oil saturated porous medium to recover the remaining oil in the presence of an electromagnetic wave. At the sintering temperature 1200°C, a mixture of hematite and YIG was obtained, suggesting a higher temperature for single phase YIG. From VSM analysis, the average magnetic saturation, coercivity and remanence are 18.17 emu/g, 21.73 Oe and 2.38 emu/g, respectively. 1.0 wt% of YIG nanofluid was prepared and subsequently injected into the presaturated porous medium in the presence of square electromagnetic wave of 13.6 MHz. As much as 43.64% of the remaining oil in place (ROIP) was recovered following the injection of 2 pore volume of YIG nanofluid.

Interfacial tension measurement tests are the effective ways to identify proper nanomaterials for enhanced oil recovery by nano/surfactant flooding. In this work zinc oxide nano-crystallites were synthesized using self-combustion technique for application in enhanced oil recovery (EOR). The synthesized sample were used to the measure interfacial tension between their aqueous phase and crude oil phase to investigate the efficiency of the nanoparticles in reduction of interfacial tension. Therefore this research is intended to investigate the effect of Zinc Oxide (ZnO) nanoparticles towards surface/interfacial tension. Practically ZnO nanoparticles were characterized using X-ray diffraction (XRD), Field Emission Scanning Electron microscope (FESEM) in order to understand its structure, size, shape and morphology. The characterization results reveal the hexagonal structure of ZnO. Pendant drop experiment was carried out to further understand the effect of nanoparticles on Interfacial Tension (IFT). Since the Zinc Oxide solution was very " cloudy " the drop phase could not be identified and the interfacial tension was not calculated by the software. Due to this reason, the Surface Tension (ST) was calculated with different concentration. The results show high value of ST 35.57 mN/m at 0.3 wt % of ZnO nanoparticles.
