The study of the composition and distribution of hydrocarbons in oil and dispersed organic matter represents a key tool for determining their genetic features. This paper presents the results of complex geochemical studies carried out on oil samples from the eastern part of the Caspian depression. The methods of adsorption and gas chromatography with mass spectrometry were used to study hydrocarbons of different oil fractions, which allowed to determine their biomarker and isotopic composition. The study also included analysis of the calculated reflectivity of vitrinite to assess the degree of catagenetic transformation of organic matter. The results obtained indicate the marine origin of the oil and distinguish its facies-genetic type, showing a predominantly marine and mixed genesis. Cross-correlation of isotope and biomarker data confirmed the genetic relationship between the oil and its potential sources. The calculated reflectivity of vitrinite allowed us to determine the degree of catagenesis of the petroleum parent rocks, indicating their early stage of catagenetic transformation. These results reflect the significance of geochemical methods of investigation for revealing the genesis of oil, its sources and the degree of catagenetic transformation, which is important for predicting the oil and gas content of sedimentary basins. © 2024, National Academy of Sciences of the Republic of Kazakhstan.
