Abstract EN

The Middle Jurassic Sargelu Formation is evaluated for its hydrocarbon generation potential in three wells near Duhok Governorate, Northern Iraq using ten borehole cutting samples analyzed by Rock-Evil pyrolysis, gas chromatography coupled with gas chromatography-mass spectrometry (MSS) and stable isotope. The results showed that the total organic carbon and genetic potential of the formation ranges from 0.5 to 11.6 wt.% and 1.7 to 66.3 mg HC/g of rock, respectively indicating fair to excellent source rock petroleum potential, with hydrogen index values between 270 to 555 mg HC/g TOC. The results also show kerogen Types II and mixed II/III reflecting thermal maturity within the oil generation zone. The estimated ratios of Pr/Ph, Pr/n-C17 and Ph/n-C18 from the extracted bitumen reveal primary accumulations of marine organic matter under reducing conditions. The δ13CSat and δ13CAro for the extracted bitumen range from -29.5 to -27.5‰ and -28.4 to -27.2‰, respectively. The biomarkers results indicate a significant contribution of marine organic matters preserved under relatively anoxic conditions.
