Abstract

One dimensional basin modelling was used to evaluate the maturity of source rocks, the history of oil generation, and expulsion in north Pazanan syncline and Pazanan, Agha-Jari, and Bangestan anticlines in south Dezful Embayment in the Zagros Basin. The oil generation history of source rocks was obtained by using the basin modelling method. Burial history analysis shows an increase in the rate of burial after the Zagros folding, which it was contemporaneous with huge sedimentation. The high rate of burial is more noticeable in the Pazanan syncline, which it plays an important role in the generation of oil from source rocks. The Sargelu, Garau and Kazhdumi source rocks in the Pazanan syncline have reached the gas-maturity stage. Trapped gas in the Pazanan field could be sourced from the syncline.
