Abstract
In sea bed logging detection of hydrocarbon reservoir is a very challenging task for shallow water and deep target. Magnitude of electromagnetic field response is very low and cannot be able to detect the deep target. To detect deep target new aluminium curve antenna is designed by using computer simulation technology (CST) software. 3D scale modeling with and without hydrocarbon was done by Finite integration method (FIM). Straight and curve antenna comparison was done in a 3D scaled marine environment. It was investigated that new design gave 158% higher magnetic field strength than straight antenna. A scale tank with a scale factor of 2000 was built to test the new designed antenna. The series of experiments were done to evaluate the performance of new design antenna with and without the presence of oil in a scale model. Magnitude verses offset (MVO) was done with new design curve antenna with and without oil. The experimental data was recorded with new design antenna with and without oil placed left and right side of receivers (R x−1 , R x−3 ) respectively. The magnitude of the EM waves of this new designed antenna increases up to 168% with hydrocarbon. Curve fitting method using MATLAB software was done to validate the MVO data of new designed antenna with and without oil. Correlation value with new design antenna also confirms the presence of oil in a scale model.
