Mesozoic and Tertiary source rocks and crude oils from six oilfields offshore SW Iran, namely Hendijan, Bahrgansar, Abouzar, Nowruz, Dorood and Foroozan, were studied by means of a variety of organic geochemical techniques. Biomarker characteristics were combined with other geochemical data to identify the source rocks which generated the oil in these fields and to reconstruct their depositional environments, and also to characterize the diagenetic and catagenic processes which have occurred. The analyzed oils show a wide range of densities (19 to 39° API) and high sulphur contents. They were generated by Type II-S organic matter; they are not biodegraded and their maturity level is generally low. Two main oil groups were identified from statistical analysis and can be correlated with different source rocks using age-specific biomarkers and isotope data. Group 1 oils include those from the Hendijan, Bahrgansar and Abouzar fields and were probably generated by a mid-Cretaceous argillaceous source rock. Group 2 oils include those from the Nowruz, Dorood and Foroozan fields, and originated from Jurassic to Early Cretaceous carbonate-rich source rocks. 4 Journal of Petroleum Geology 28 ARTICULO Rabbani, A.R. 46204 Kamali, M.R. 32275 181933 181933 0 0 0 0 249752 BAAB BAAB 2026-03-05 200053973 0 200053973 2026-03-05 23:52:04 2026-03-05 ARTICULO
