Development of a Novel Terminated Insulated Antenna in a Conducting Medium

Seabed Logging is an application of marine Control Source Electromagnetic
(CSEM) sounding, which can be applied to detect and characterize hydrocarbon bearing
reservoirs in deep water areas. The basis of the approach is the use of a mobile Horizontal
Electric Dipole (HED) source and an array of seafloor electric field receivers. This
document describes the approach used in development of a novel terminated insulated
antenna in a conducting medium. The main purpose of this project is to develop a new
design of antenna that could function more efficient compared to HED. The developed
antenna will act as a source that propagates EM wave for hydrocarbon detection
purposes. The project includes research and study on the conceptual knowledge of EM
itself. Experimental works using proposed design were carried out in order to choose the
best design. In order to complete the objectives of this project, simulations also were
done using CST EM STUDIO (CST EMS). These simulations were important to this
project due to the limitation of equipment used such as the low current supply supplied
by the function generator as well as for precaution and safety purposes. Results from
experiments and simulations conducted show that circular loop antenna produces stronger
magnetic field compared to dipole antenna. The improvement of the antenna also has
been successfully done and the result was satisfying as the induced magnetic field from
the antenna increases.
