AB  - Molecular mass distributions of components of 24 isobaric homologous series of aromatic hydrocarbons were established in crude oils from Lower Cretaceous (Zuunbayan oil field) and Jurassic (Tamsagbulag oil field) deposits. The concentrations of individual C-10-C-14 biarenes and C-14-C-17 triarenes in these oils were determined, the salient features of the isomer composition of these hydrocarbons were revealed, and this composition was correlated with the thermodynamic stability of the compounds.

AB  - The average structural characteristics of oily and resinous components of nine crude oils of various types from different Miocene horizons of the Sirakovo and Bradarac-Maljurevac oil fields (Serbia), as well as the mass-spectrometrically established hydrocarbon-group composition of these oils, are described. The most abundant components of crudes from both oil fields are mono- and bicyclanes bearing long alkyl substituents. It was found that there is no universal trend in the chemical type of the oils with the occurrence depth of the producing zones in these fields, that is, oils are enriched in aliphatic hydrocarbons with depth in the Sirakovo oil field and in naphthene hydrocarbons in the Bradarac field. These trends cannot be explained by microbial degradation processes or by the catagenetic alteration of petroleum composition in the Earth's interior and indicate a low level of thermal maturity of the source organic matter that gave rise to the hydrocarbon systems in question. A certain parallelism of variation in the structural parameters of hydrocarbonaceous and heteroorganic (resinous) components of the oils depending on natural factors is noted.

AB  - A correlation analysis of maturation parameters was carried out on 14 crude oil samples from nine oil fields on Sakhalin Island (Russia). The oils were taken from reservoir rocks of Miocene age at depths ranging from 73 to 2841 m. On the basis of GC analysis of the alkane fraction (n-alkanes and the isoprenoid alkanes pristane and phytane) as well as on the basis of the abundance of demethylated hopanes (GC-MS analysis, m/z 177), it is assumed that the oils are either biodegraded or are a mixture of biodegraded and nonbiodegraded oils. Therefore, their maturation is assessed on the basis of the distribution and abundance of tricyclic aromatic hydrocarbons that are more resistant to biodegradation than alkane-type biological markers. The oils may be classified into three groups on the basis of the well-established maturation parameter MPI 3: highly mature (group I), moderately mature (group II) and immature (group III). The correlation analysis shows that the percentage of phenanthrene [P] in the tricyclic aromatic fraction of the oils of the Sakhalin oil fields can be used as a maturation parameter. The highly mature oils (group I) were found to have a [P] value of more than 14%; the moderately mature oils (group II) have values of 7-14%, and the immature oils (group III) a value of less than 7%. The very good correlation between MPI 3 and [P] also indicates that parallel to methylphenanthrene isomerization, dealkylation also occurs in the reservoir rocks. By correlation analysis it is shown that these reactions are, to a great extent, determined by the depth of the reservoir rocks. (C) 2001 Elsevier Science Ltd. All rights reserved.

AB  - GC-MS was applied in order to determine the effects of biodegradation on steranes and terpanes in crude oils. Sterane and tcrpane maturation parameters were correlated in 36 crude oils, biodegraded to various degrees (28 samples originate from the SE part of the Pannonian Basin, Yugoslavia, and X samples were obtained from the oil fields of Eastern Russia). The absence of any correlation between terpane maturation parameters indicated that terpane isomers are highly altered during biodegradation. On the other hand, satisfactory correlation between sterane parameters indicated that their abundance and distribution is less affected by microbial activity, and it can be concluded that sterane parameters represent more reliable maturation parameters.
