“…The values suggest that the organic matter of the organic-rich zones is from algae organisms and marine environments. This conclusion is consistent with the reported sedimentary environment conditions of Sargelu Formation in north Iraq (Abdula 2015;El Kammar et al 2015;Fatah and Mohialdeen 2016).…”

“…In addition, the Early and Middle Jurassic strata are sources of a significant amount of petroleum (Klemme 1994). The Jurassic source rocks are sources of hydrocarbon for the Jurassic-Tertiary reservoirs in the Mesopotamian Basin (Abdula 2015;Abeed et al 2011;Alsharhan et al 2014;Pitman et al 2004). Moreover, they may have unconventional shale oil and shale gas in areas which are within oil and gas windows, respectively (Aqrawi and Badics 2015).…”

The petroleum system with Jurassic source rocks is an important part of the hydrocarbons discovered in the Middle East. Limited studies have been done on the Jurassic intervals in the 26,500 km 2 Abadan Plain in southwest Iran, mainly due to the deep burial and a limited number of wells that reach the basal Jurassic successions. The goal of this study was to evaluate the Jurassic organic-rich intervals and shale gas play in the Darquain field using organic geochemistry, organic petrography, biomarker analysis, and basin modelling methods. This study showed that organic-rich zones present in the Jurassic intervals of Darquain field could be sources of conventional and unconventional gas reserves. The organic matter content of samples from the organic-rich zones corresponds to medium-to-high-sulphur kerogen Type II-S marine origin. The biomarker characteristics of organic-rich zones indicate carbonate source rocks that contain marine organic matter. The biomarker results also suggest a marine environment with reducing conditions for the source rocks. The constructed thermal model for four pseudo-wells indicates that, in the kitchen area of the Jurassic gas reserve, methane has been generated in the Sargelu and Neyriz source rocks from Early Cretaceous to recent times and the transformation ratio of organic matter is more than 97%. These organic-rich zones with high initial total organic carbon (TOC) are in the gas maturity stage [1.5-2.2% vitrinite reflectance in oil (Ro)] and could be good unconventional gas reserves and gas source rocks. The model also indicates that there is a huge quantity of retained gas within the Jurassic organic-rich intervals.

“…The lower part of the Surmeh Formation in Iran and Dhruma Formation in Saudi Arabia is the age equivalent to the Sargelu Formation (Jassim and Buday, 2006). Abdula (2010;2014) in his study on the Sargelu Formation concluded that the OM of the Sargelu can be Type II and III kerogen. The most recent study on the Sargelu Formation in Miran Oil Field by Fatah and Mohialdeen (2016) reveal that the main kerogen type of the Sargelu Formation is a mixed Type II/III kerogen and is thermally post mature and in the gas generation zone.…”

In this study, source rock characteristics and lateral changes in thermal maturity of the Sargelu Formation (Middle Jurassic) in three outcrops were studied. The formation’s outcrops can be found in the High Folded, and Imbricated Zones of Iraqi Tectonic Division. In order to achieve the main goals of this study, the Gas chromatography mass spectrometry (GC-MS) and Rock-Eval pyrolysis were performed on the organic matter (OM) of the Sargelu sediments. Pristane/Phytane ratios for analyzed samples indicate reducing conditions (anoxic) during sedimentation. Moreover, based on C29/C30 hopanes ratios the sediments of the Sargelu Formation associated with clay- rich source rock. Biomarker thermal maturity parameters display that all samples are thermally in Oil Window at least. The biomarker findings reveal that the samples of Walasimt and Barsarin are seem more mature than Banik section. The values for TOC% of the Sargelu Formation may show Excellent, Very Good, and Poor quality source rock. The Pyrolysis executed for studied samples revealed the kerogen in Banik section belongs to Types II and III (Probably Oil/Gas- prone), while Barsarin and Walasimt sections obtained Types III-IV Kerogen (Gas- prone). Pyrolysis parameters suggested Early Mature Stage in Banik, While Overmature in Barsarin and Walasimt. The data also shows that organic matter of the Sargelu Formation in Banik section is in Oil Widow, while in Barsarin and Walasimt is in Gas Window.

“…The common source rock for hydrocarbon generation in the Folded Belt and Zagros Thrust zone is the carbonate and shale rock units of the Jurassic mainly found as part of the Sargelu Formation (Pitman et al, 2004). The organic matter (OM) of the Sargelu Formation is classified as type II and III kerogens (Odisho and Othman, 1992;Abdula, 2010Abdula, , 2015. The OM is thermally in the post mature stage and within the gas-generation zone in the Miran Oil Field (Fatah and Mohialdeen, 2016).…”
