This 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 usingQualitative Analysis B.07.00 and quantified with MS Quantitative Analysis B.07.00software 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. Thefindings of the aromatic biomarkers analysis certify the already existing geochemical informationrelated to Prinos basin, and substantiate that the oils are nonbiodegradatedand immature. They were formed in shale and carbonate source rock formations,with more terrestrial and less marine contribution of organic material, in a salinehypersalineenvironment. In addition the polyaromatic hydrocarbons are found to bemostly combustion-derived and less from natural biological precursors.
