Numerical modelling tools were used in atypical petroleum system in an onshore multi-phasic Paleozoic basin in northwest of Brazil. The Parnaíba Basin is the most important hub of electrical energy generation in Brazil, through thermal power plants connected directly in the power lines grid in an innovative system called Reservoir to Wire model (R2R). In this Devonian/Eo-Carboniferous petroleum system, natural gas generation is triggered by magmatic intrusion along the source rock, and the diabase sills also form the trap and the seal. Incorporation of new lithogeochemistry, TOC, Pyrolisys, Vitrinite and X-Ray data allowed to narrow the uncertainty in the models and improve the accuracy of the predictions of occurrence of hydrocarbons.
