DESIGN AND DEVELOPMENT OF ANTENNA FOR THE SCALE DOWN MODEL OF A SEA BED LOGGING (SBL) FACILITY

Controlled-source electromagnetic (CSEM) methods had been used for marine geological surveying for many years. The electromagnetic (EM) technique for marine hydrocarbon prospecting which first used commercially, has gained wide industry acceptance and many improvements have been made to operating practices, survey equipment, and data-processing techniques in the past few years. The objective of this project is to improve a small scale of SBL model measurement facility that had been earlier developed at Universiti Teknologi Petronas (UTP), to develop a better, well develop electrical dipole antenna to collect experimental data such as resistance and magnetic field measurement, and to verify the result through theoretical modeling. The lab scale model of SBL system was completed with several specification changes and modifications. Modifications are needed in order to simulate different skin depth effect. Theoretical modeling is done before lab experimentation is performed. Several experimentations have been made and the result is not very accurate. It is still unclear if there are something buried in the sand from the reading of the receiver. Therefore several factors have been identified to be the cause of the invalid result. Thus, future works based on current problem are also suggested.
