| Abstract | Basin modelling of the central area in the Cuu Long basin has been carried out using the geological, geophysical and geochemical data. The Oligocene source rocks (including E/Pre E, Dlower, Dupper and C sequence) are identified as fair to excellent source rocks richness and mainly classified as oil-prone sources (Kerogen Type I) with lacustrine or fluvio-lacustrine organic facies. The pooled hydrocarbons in the study area are interpreted to have sourced from lacustrine or fluvio-lacustrine organic facies and they are geochemically correlated with the bitumen extracts from the D shale based on the biomarkers study. The pooled hydrocarbons seem to be generated from the source rocks at peak of maturity (approximately 0.8%-1%Ro) as indicative of Ts/(Ts+Tm) trisnorhopanes ratio. The timing and amount of hydrocarbon generation for the source rocks were modeled and calculated based on the above source rocks identification and oil-source correlation. In general, oils were generated in the late Oligocene- early Miocene time and then gases were generated relatively in the study area and this critical timing would give favorable conditions for trapping hydrocarbon in the possible fractured basement reservoir and E/Pre E, Dlower, C and BI sequence sands reservoir, which have been formed since the latest Oligocene time respectively. Based on the kinetics modeling approach, the total amount of hydrocarbon generation was calculated as large are 2000 billions of barrels of hydrocarbon from the major depocentres in the study area. The large amount of hydrocarbon, which has been generated since the late Oligocene time, is an attractive factor for further exploration activities in the Cuu Long basin. |
