Analysis and identification of biomarkers in the composition of petroleum: the oil origin of the Gunashli deposit in the Republic of Azerbaijan
Abstract
The article presents the results of a study of the content of metal porphyrins in the composition of crude oil from platforms No 8 and No 14 of the Gunashli oilfield in Republic of Azerbaijan using IR, UV spectroscopy and electron paramagnetic resonance. By means of these methods, it was not detected metal porphyrin, which is a biomarker in the composition of the studied samples of Gunashli crude oil. It was found that oil samples before and after gamma irradiation also do not contain metal porphyrins. This indicator can be used to determine the genesis of oil. A conclusion is made about the abiogenic synthesis of hydrocarbons from the Gunashli oil.
