Investigating potential source rocks in oilfields is important. In this study, in addition to evaluating the hydrocarbon potential, the Arrhenius kinetic model was used to more accurately assess the source rock maturity status as well as the percentage of oil generation in the Parsi oilfield. In the Arrhenius model, the rate of kerogen decomposition is very important. In this research, some source rocks that have been tested by thermal pyrolysis were kinetically analyzed and the source rock conversion ratio (TR) was determined. Based on the results of burial history and thermal modeling, it was found that Kazhdumi and Pabdeh formations were in the oil window well while Gurpi formation did not enter the oil window due to poor organic matter content (TR = 0). Therefore, among the Kazhdomi, Gurpi and Pabdeh formations in the Parsi oilfield, Kazhdumi formation is considered as the main and most effective source rock of this oilfield with high TTI and TR = 100.
