While previously published studies contain 1D petroleum system models, this study utilizes advanced 3D modeling techniques to simulate basin’s history and thermal maturity. The study integrates multiple types of data into one large scale model which is simulated and calibrated to yield most accurate results. The project consisted on five phases – structural framework construction, geochemical data integration, preliminary 1D simulations, 3D predictive model simulation and calibration. Because of the extensive workflow, it was possible to achieve high degree of calibration. The results indicate high degree of thermal maturity within the Permian petroleum system with high transformation ration values. For the Cretaceous petroleum system, the results indicate high degree of thermal maturity and transformation rations in the lower Cretaceous with decreasing thermal maturity for the upper Cretaceous formations. The cumulative erosion map indicates that majority of the erosion has taken place on the outskirts of the basin. Migration modeling indicates that hydrocarbons migrated upwards and outwards of the center of the basin. Majority of the accumulations are located on the anticlines surrounding the basin and few are in the northern part of the basin. Additionally, some of the petroleum has leaked outside of the basin.
