The improvements of source rock analyses show that samples of Lower Baong and Pre-Baong are the most favourable source rocks. Vertical migration seems to play a very important role in the trapping mechanism of hydrocarbon in the Aru area, North Sumatra, due to the fact that the producing oil zones are mostly the Lower Keutapang and partly the Middle Baong sands which are located above the source rock. his migration may be controlled by faults, fractures and overpressured zones. By using seismic reflection and well data, the position of faults and overpressured zones can be recognized. Further understanding of the trapping mechanism, may encourage exploration efforts in the Aru area.
