Nowadays a control source electromagnetic method is used for offshore hydrocarbon exploration. Hydrocarbon detection in Sea Bed Logging (SBL) is a very challenging task for shallow water-deep target reservoirs. Electromagnetic field response of an antenna cannot be able to detect shallow water-deep target due to the air waves effect in seabed logging environment. This work premise deals with a new antenna design for shallow water-deep target hydrocarbon exploration. A new curved antenna was designed by using computer simulation technology software (CST). CST software was used to detect deep target hydrocarbon between I OOOm to 5000m underneath seabed. The model area was assigned as ( 40x40 km) to replicate the real seabed environment with various target depths. Magnitude verses offset with change of frequencies, and change of curvature (h= R, h <R) of antenna comparisons for different target depths were done in this model.
