This paper presents the study of new method in finding hydrocarbon reservoirs which is Electromagnetic Sea Bed Logging (SBL ). This study will help to improve the effectiveness of SBL method in shallow water environment. SBL was introduced to overcome some limitations on the recent technology of finding the hydrocarbon reservoirs. Recent technology that is being used widely is seismic method via offset seismic technique which can help to estimate other characteristics of potential hydrocarbon reservoirs such as pore fluid and other rock properties. However, this method cannot distinguish the presence of hydrocarbon reservoir or gas-charged water (saline water) [1]. SBL can curb this problem since it detects the resistivity of the hydrocarbon which is relatively higher than saline water and sediments around it. However, at shallow water environment, this method will have some limitation due to the presence of the air waves. Air wave is the energy propagates from the source through the atmosphere to the receiver. Since air wave also have high resistivity, thus, it is hard to identify the presence of HC reservoir accurately. The study is started with some literature review first before going to do the simulation. Here, the author presents the literature review that had been done by him and the author also presents together data from Troll West gas Province offshore Norway which uses this method to detect the buried hydrocarbon reservoir. Other than that, the author also presents the methodology time line for his project on this topic.
