In this study, the sediments of Kazhdumi Formation were evaluated as a possible source rock in Ahwaz, Aghajari, Parsi, Kilorkrim and Masjed Soleiman oil fields in Zagros basin located in southwestern Iran. For this purpose, the Arrhenius kinetic model was used to evaluate the maturity of the source rock as well as to investigate oil generation. According to the information obtained, the dominant kerogen in the Kazhdumi Formation is type II. Also, based on the values obtained from the Rock-Eval pyrolysis, this Formation has fully entered the oil window and has a high­ . Therefore, the kerogen of this Formation was classified in very good source rock, which has a very good hydrocarbon potential. Similar results were obtained in this study based on the Arneus kinetic model. Accordingly, the Transformation rateof hydrocarbons in different oil fields were the range of 66 to 100%. These changes are mainly due to different burial history in the oilfields studied.
