Forecasting the presence of hydrocarbon in Moc Tinh Tay prospect, block 05-3, Nam Con Son basin by 3D petroleum

Tóm tắt

Moc Tinh Tay is located to the west of the Moc Tinh discovery, Block 05-3, Nam Con Son basin. Results of exploration wells and production wells clarified the petroleum potential of Block 05-3, especially Moc Tinh area, including Moc Tinh Tay structure.

The purpose of this paper is to understand, by 3D basin modelling, the generation, migration and accumulation histories of oil and gas from source rock; and evaluate the presence of hydrocarbons in Moc Tinh Tay prospect to minimise the risk of oil and gas exploration in the study area.

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 24 Ma. It is
in oil window at 13 Ma, and reached dry gas phase at 10Ma to the present time. The Lower Miocene source rock has generated hydrocarbon
since 12 Ma. It is in oil window from 5.5 Ma and in gas phase in almost the entire area at the present.
