The Use of aromatic biomarkers in the geochemical characterization of oil. Application to Prinos Basin oilsThe Use of aromatic biomarkers in the geochemical characterization of oil. Application to Prinos Basin oils Μεταπτυχιακή Διατριβή Master Thesis 2018-12-102018enThis study focuses on the geochemical evaluation of oils based on the composition of the aromatic fraction. A method was developed using Gas Chromatography - Mass Spectrometry (GC-MS), for the qualitative and quantitative determination of the aromatic compounds. The method was applied on a set of ten samples from five different wells (K1, PN2, SK4, PB, and E1) of the Prinos basin (Greece). The analysis was carried out using the GC-MS analyzer GC: 7890A, MS: 5975C from Agilent Technologies. The aromatic compounds were identified based on their MS spectrum using Qualitative Analysis B.07.00 and quantified with MS Quantitative Analysis B.07.00 software packages. A series of 70 compounds were identified and evaluated as biomarkers, including naphthalenes, cadalene, dibenzothiophenes, phenanthrenes, anthracenes, pyrenes, perylene, fluoranthrenes, florenes, chrysenes and their alkylated versions. The findings of the aromatic biomarkers analysis certify the already existing geochemical information related to Prinos basin, and substantiate that the oils are nonbiodegradated and immature. They were formed in shale and carbonate source rock formations, with more terrestrial and less marine contribution of organic material, in a salinehypersaline environment. In addition the polyaromatic hydrocarbons are found to be mostly combustion-derived and less from natural biological precursors.http://creativecommons.org/licenses/by-nc-nd/4.0/Πολυτεχνείο Κρήτης::Σχολή Μηχανικών Ορυκτών ΠόρωνTriantos_Antonios-Stavros_MSc_2018.pdfChania [Greece]Library of TUC2018-12-08application/pdf7.2 MBfree Triantos Antonios-Stavros Τριαντος Αντωνιος-Σταυρος Pasadakis Nikos Πασαδακης Νικος Kallithrakas-Kontos Nikolaos Καλλιθρακας-Κοντος Νικολαος Κιομουρτζή Πασχαλιά Kiomourtzi Paschalia Πολυτεχνείο Κρήτης Technical University of Crete Prinos basin Geochemical characterization Organic geochemistry Geochemistry Γεωχημεία Αρωματικοί βιοδείκτες GC-MS Mass spectroscopy Gas chromatography Aromatic biomakers
