The Nam Con Son basin center areas composed blocks 05-3/11, 06/94, 11-2 etc., in these, the deepest area belongs to block 05-3/11. Block 05-3/11 located next to gas and condensate fields cluster named Hải Thạch, Mộc Tinh. To able lo evaluate the remain areas in this block, petroleum 30 modeling is built for assessing the source rocks features which contain risks in this block. By integrating the seismic dala, paleo environment, source rock data, temperature data, model indicates source rock properties as well as the relationship between generation timing and trap forming. The study illustrates the eastern side of block 05.3/11, Oligocene and Lower Miocene source rocks start to generate at around 10Ma and continue until present with main production are gas and condensate. Whereas, source rocks in the western side have higher maiurity level as compared with the eastern. At 5Ma. Oligocene source rock in the western side is in dry gas and overmature in deep areas. Lower Miocene source rock had been generating until 3-4Ma. When it compared between generation timing and trap forming in two areas, the prospects in western side contain more risks than eastern area.
