From 3D seismic interpretation and well logs five of the strongest reflectors of the Upper Jurassic Source Rock along the Southern DGC were mapped, the markers were correlated with biostratigraphic and geochemical data. It was generated a simple 3D basin model. The Southern DCG experienced a strong subsidence during Kimmeridgian with tilted fault blocks forming the three most important mini Basins of this area: Rosa, Poul and Igor. There was a uniform subsidence along the entire basin during the Late Kimmeridgian while the salt structures started to form in the Salt Dome Province. A large progradational system from south to north is seen, with minor retrogradations. The subsidence rate diminished during the Volgian period and a fast regression was recorded. The Volgian is very condensed or absente in the Salt Dome Province where the salt structures pierced in a passive way. The main HC expulsion took place in the Rosa and Poul Basin. The latest Jurassic Bo Member is not the principal source rock in the Southern Central Graben because it is immature. In this area the Lower Kimmeridgian is the main oil generator. The Basin Modelling software calculates the maturity in the top surface of each package, and it was found that the HC expulsion rose up 40% of volume with the two artificial intralayers per package . The statistical mean of Oil expulsion for all the TOC, HI and temperature variants range from 71500 to 154500 bbl of oil and from 110000 to 240000 bcf of gas.
