Petroleum Geochemistry and Burial History Modeling in the Azadegan Oil Field

Geochemical analysis on oil samples from Gurpi and Sarvak Formation in Azadegan oil field includes liquid chromatography, gas chromatography-mass spectrometry (GCMS), stable isotope carbon and biomarkers studies. Liquid chromatography show that, the type of oil is aromatic intermediate, which originate from type II organic matter and deposited under reducing conditions. Isotope and Biomarker studies are suggest Garu and kazhdomi formation as source rock in Azadegan oil field. Burial history reconstruction and thermal modeling indicate that oil generation and migration from Garu source rock would have begun from 45 Ma and 30 Ma ago and from Kazhdomi source rock begin from 6 Ma and 3 Ma ago.
