In this study, Lower Miocene and Oligocene source rocks are fair to very good source richness and essentially contain kerogen type III and a mix of type III and type II and has fair to good gas generation potential. Oligocene source rock has generated hydrocarbon since 24Ma. It is in oil window at 13Ma, and reached dry gas phase at 10Ma to the present time. The Lower Miocene source rock has generated hydrocarbon since 12Ma. It is in oil window from and in gas phase in almost the entire area at the present. | Forecasting the presence of hydrocarbon in moc tinh tay prospect, block 05-3, nam con son basin by 3D petroleum system modelling
