Abstract

Electromagnetic (EM) technology called Seabed Logging (SBL) has recently been used for hydrocarbon exploration. Seabed logging (SBL) is an application of marine controlled source electromagnetic (CSEM) method which is used to detect the location of oil reservoir. A recently developed transmitter IS usmg Horizontal Electric Dipole (HED) transmitter 1=1 on electromagnetic (EM) surveying technique. The technique has proven particularly useful for detecting thin and highly resistive layers of hydrocarbon reservoirs. However, to detect the hydrocarbon reservoirs at very deep seawater still remains a challenge. There are many limitations of the conventional HED transmitter in terms of depth penetration for deep target (~2.5km). This project has come out to further improve the current design of transmitter that can penetrate more below the seafloor. This project consists of simulation and modeling the prototype of EM antenna. Aluminum is the best material to this design since it is easy to fabricate, light, cheaper than copper and has high resistive corrosion. The shape of half ring antenna gives greatest improvement on the amplification of 102.19% as compared to the straight shape and 20.66% compared to ring shape. Further improvement to the current design was done by combining four half ring antennas which is called Quadrapole antenna. The Quadrapole antenna with parallel connection and feeding points at the center gives percentage difference of 196.77.88%. The combination of magnetic feeders and Quadrapole antenna enhance the output of EM wave with 445.76% increment compared to the Quadrapole antenna without magnetic feeders.
