“…This zone is mainly characterized by the presence of 15-20 km anticlines which was developed from bending mechanism on the Hormuz Salt. However, these anticlines have been divided into five different trends by thrust faults with the presence of salt domes (Bordenave 2003). The impact of these salt domes on the anticline can be used as the most important structural features in this region.…”

“…However, the geology of this formation is well described (see Table 1) (Kavoosi et al 2006;Jamalian et al 2010;Feghhi et al 2012;Abyat et al 2012Abyat et al , 2014Mahbaz et al 2012;Shakeri and Parham 2013;Jamalian and Adabi 2014;Soleimani et al 2017), considerable uncertainty related to the maturity and quality of source rocks still exists which may affect on the reliability of geochemical models. Consequently, this study focuses on characterizing the Fahliyan Formation with regards to the depositional environment, organic matter, source rock, and thermal maturity in two fields in the Iranian Fars sector.…”

Three crude oil samples from the Fahliyan Formation in ‘KG’ and ‘F’ fields in the northwest Persian Gulf, namely KG-031, F9A-3H and F15-3H for the geochemical study. In this study, the physicochemical properties, gas chromatography (GC, GC Mass) and (Detailed Hydrocarbon Analysis) DHA analyses for the collected Fahliyan oils were carried out. The API, Trace Element (Ni, V) and S% parameters indicated that the Fahliyan oil was generated from a source rock which deposited in reducing environment condition with a carbonate-shale compound lithology. Moreover, low pour point, higher S% and low viscosity parameters of “KG” sample confirmed the existence of medium oil characteristics in this field. In addition, the geochemical outcomes of GC, GC–MS and DHA analyses indicated that the ‘KG’ oils are more aromatic compared with ‘F’ oil; while biomarkers revealed that Fahliyan reservoir oil is highly mature and was formed from a carbonate source rock containing types II, III kerogen. Thus, sterane/hopane biomarkers (C24/C23 and C22/C21 ratios) revealed that Fahliyan oil originated from carbonate source rocks deposited in an anoxic to dysoxic environment, which is consistent with the above analyses. It was identified that the source rock age is early Cretaceous to late Jurassic. It can be reported that the Fahliyan oils from both fields were generated in the same source rock and have almost the same physical properties, and will have the same production strategy.
