ABSTRACT
Direct detection of hydrocarbon by an active source using electromagnetic (EM) energy termed at seabed logging (SBL) has shown very promising results. However, powerful horizontal electrical dipole (HED) which could improve data acquisition still remains a challenge. This paper the presents development of a twin dipole with yttrium iron garnet based magnetic feeder. The toroid shape yttrium iron garnet samples were prepared using sol gel technique. The starting solution is a mixture of iron nitrate Fe(NO3)3.9H2O and yttrium nitrate Y(NO3)3.6H2O which were dissolved in 150 mL of nitric acid, HNO3. The mixtures were stirred continuously, at about 250 r.p.m, at 70° C until the formation of a gel was observed. The gel was dried at 110 ° C in an oven to remove the unneeded water. The dried powder was calcined at 900° C, 1100° C and 1200° C for 4 hours in air. The sample was then characterized by X-Ray Diffraction analysis (XRD) to confirm the garnet phase. The sintered powder was characterized at different temperature by X-ray diffraction analysis and Raman Spectroscopy was used to study the vibration of atoms of the samples. Finally, Field Emission Scanning Electron Microscopy (FESEM) was used to study the surface morphology of the samples. The XRD results showed that, the best garnet cubic phase giving (4 2 0) plane of the Y3Fe5O12 crystallite appeared at 33.30 of the 2 theta. It was observed that improvement of peak to peak voltage of the EM detectors by more than 400% was performed by the transmitter with the Y3Fe5O12 magnetic feeder (UTP28). In addition these twin dipoles were able to detect EM waves at more than 70 meters. The dipole was termed “intelligent” due to the ability to change from HED to vertical magnetic dipoles (VMD) mode.
