Abstract:

In this study, one and two-dimensional models of petroleum systems were constructed in the internal part of the Fars region. Based on the results obtained from one-dimensional modeling and the study of thermal maturation history, the Sarchahan Formation is considered the main source rock of the Paleozoic petroleum system, which started hydrocarbon generation about 130 to 140 million years ago. The liquid hydrocarbon content in wells A and B is estimated to be 720 and 5100 (Kg/m2) respectively, and the gas hydrocarbon content is estimated to be 70 and 600 (Kg/m2). Furthermore, based on the results of two-dimensional modeling, the younger petroleum system source rocks such as the Cretaceous and younger source rocks are thermally immature and have not entered into the oil window. According to the migration modeling results, the most important factor in the movement of hydrocarbon fluids prior to the Zagros orogeny is vertical migration in the career layers, but after this orogeny and tectonic compression, the horizontal migration component has also become active.
