“…2) was deposited during the Barremian in generally shallow oxic environment (James and Wynd 1965). However, the environment remained dis-oxic in the Lurestan and S-W Dezful Embayment (Bordenave and Huc 1995). In the Abadan Plain and in most of the Dezful Embayment, the Gadvan Formation is dominated by brownish-yellow marl and argillaceous limestone (Kent et al 1951;Fakour et al 2010).…”

“…The average values of the present time hydrogen index (HI) are 122 and 213 mgHC/g TOC in the Gadvan and Garau formations, respectively. Regarding the Bordenave and Huc (1995) plot in Fig. 3, it can be concluded that the Gadvan is a marginal source rock.…”

“…Among the Cretaceous succession, the Kazhdumi, Gadvan and Garau formations have source rock characteristics and contributed to the generation of most of the oil and associated gas reserves already discovered. The Albian Kazhdumi Formation has been investigated in a number of previous studies (Bordenave and Burwood 1990;Bordenave and Huc 1995;Rabbani and Bagheri Tirtashi 2010;Alizadeh et al 2012;Mashhadi et al 2014;Mashhadi and Rabbani 2015). Early Cretaceous source intervals in southern Iran comprise the Gadvan and Garau formations, which are the main subject of this study.…”

The Khalfani anticline is located in the Coastal Fars (Zagros, adjacent Persian Gulf). This anticline with Northwest-Southeast trend is a fault bend fold. In the study area, the Khalfani anticline has increased elevation from West to East with three distinct humps. The major faults in the study area are the Hendurabi and the Razak sinistral strike slip faults. Because analysis of fold and their folding styles in different parts system is important, the analysis of folding style elements is necessary for structural studies. The main aim of this research is structural style analysis based on fold style elements in the Khalfani anticline. This analysis is important for progress in hydrocarbons exploration in the Coastal Fars area. In this research, we used Tectonics FP and Global Mapper Software for preparing some data in our study. In addition, we used the common classification of folds for our research. Based on given results, the folding pattern of this anticline has indicated that the fold style is same in different parts of the Khalfani anticline. In the study area, based on classifications of fold in different methods, fold style is same together. Fold, with close sideways requires special attention as structural view; then the Khalfani Anticline with close style in all parts has special deformation and folding style. It seems that in the study area, folding style and variation of structural style have been created by effect of the Razak and the Hendurabi sinistral strike slip fault. Because these faults are basement or deep-seated faults, special folding style and special deformation can be formed in the study area. In addition, the Khalfani anticline in the study area has restricted within the Razak and the Hendurabi sinistral strike slip faults.

Jurassic succession has resulted in prolific oil and gas reservoirs in southwest Iran. In order to geochemically investigate the Jurassic petroleum system and assess the source rock of these hydrocarbons, 32 source rock samples (from well cutting and surface section) and 4 condensate samples were analysed using geochemical approaches. Rock-Eval pyrolysis and vitrinite reflectance measurement were done on rock samples. Then, condensate samples and source rock extracts were subjected to gas chromatography, gas chromatography-mass spectrometry and isotopic analyses in order to establish oil-oil and oil-source rock correlation. The hydrocarbon generation prediction was then confirmed by petroleum system modelling. The results indicated that the middle Jurassic Sargelu Formation with average total organic carbon (TOC) and hydrogen index values of 3.8% and 600 mg HC/g TOC, respectively, can be classified as good to excellent source rock with kerogen of type II. The maturity indicators revealed late oil to wet gas generation window for the Jurassic Sargelu Formation. Biomarker parameters showed marine carbonate source rock with advanced level of thermal maturity for the source rock of the condensates. Furthermore, there were good correlations between Jurassic Sargelu Formation and the studied oil and condensate samples which proved the Sargelu Formation as the main source rock of the Jurassic petroleum system in the study area. The basin modelling results also confirmed late oil to wet gas window maturity for the Sargelu Formation enabling it as a source rock for generating gas condensate accumulation in southwest Iran. The hydrocarbon generation from Sargelu Formation began in the late Cretaceous and its peak expulsion occurred in the Miocene time.
