Abstract

Today control source electromagnetic method is used for offshore hydrocarbon exploration. Hydrocarbon detection in sea bed logging (SBL) is a very challenging task for deep target hydrocarbon reservoir. In Seabed Logging (SBL) method, antenna is used as a transmitter and device to radiate electromagnetic waves in free space. Response of electromagnetic (EM) field from marine environment is very low and it is difficult to predict deep target reservoir. This work premise deals with developing new transmitters which enhance the detection and focusing ability for deep target hydrocarbon exploration. Aluminum is chosen as the materials for building the new transmitter. Conventional and new EM antennas at 0.125 Hz frequency will be used in modeling for the detection of deep target hydrocarbon reservoir. The proposed area of the seabed model and scaled tank model which is 100 km by 100 km and 9 m by 2.2 m will be simulated by using Computational Simulation Technology (CST). Comparison in term of electric field and magnetic field value were done to determine the ability of the new transmitters. In term of detection, the 0.3r curve transmitter was better compare to the new transmitter, 0.3r bi-curve transmitter. However, 0.3r bi-curve transmitter has better ability in focusing the waves which allow the waves to penetrate deeper into the sediments.
