AB  - Twenty three crude oils from the Serbian part of the Pannonian Basin (14 from the Vojvodina Province and 9 from the Drmno Depression) were investigated, aimed at an evaluation of oil-oil maturity correlation parameters based on the distribution and abundance of saturated biomarkers and alkylarene constituents. Factor and cluster analyses were used for this purpose. Factor analyses using varimax rotation were first run separately, i.e., of maturity parameters based on the abundance of (a) n-alkanes and isoprenoids, (b) steranes and triterpanes, (c) alkylnaphthalenes, and (d) alkylphenanthrenes. These analyses yielded 9 important "maturity factors". Eight of them, showing higher than 30 % of variance, were further involved in another factor analysis, as well as in cluster analysis using the Ward method. In this way, all maturity parameters based on saturated biomarkers and alkylarenes were evaluated and ranged, considering the fact that the observed factors represented their linear combinations. The results showed that in the correlation of crude oils from the Serbian part of the Pannonian Basin, the most important were maturity parameters based on isomerization reactions involving one methyl group in thermodynamically less stable alpha-methylnaphthalenes, ethylnaphthalenes, dimethylnaphthalenes and methylphenanthrenes, and their change into more stable isomers with the methyl group in the beta-position in the aromatic ring. Processes constituting high loadings factor 2 and factor 3 parameters were also defined. Hierarchy between the "factors" and parameters were controlled, and approved, by cluster analysis using the Ward method. Finally, the investigated crude oils were correlated by factor and cluster analyses, using all the important "maturity factors". Differences in maturity were observed between the Vojvodina and Drmno Depression crude oils, as well as between oils originating from South Banat, North Banat and the Velebit oil field (Vojvodina locality).

AB  - Hierarchy of triterpane, sterane, naphthalene and phenanthrene maturation parameters in oil-source rock correlations (Drinno depression, southeastern part of the Pannonian Basin, Serbia and Montenegro) was evaluated. Different triterpane and sterane parameters were found to be very similar in all investigated samples. Phenanthrene and naphthalene maturation parameters demonstrated much less uniformity, and thus higher applicability. In order to establish a detailed hierarchy of these maturation parameters, the factor analysis was used. Parameters based on isomerization reactions (alpha - gt beta) of methylnaphthatenes and methylphenanthrenes, having high loadings, defined the statistically most significant factor 1. Parameters based on dealkylation processes of dimethyl- and trimethylphenanthrenes into methylphenanthrenes, having extremely high loadings values, determined factor 2. In the last significant, factor 3, high loadings were observed with triterpane and sterane parameters. The factor analysis involving just the phenanthrene and naphthalene isomerization parameters, classified methylphenanthrene isomerization parameters into factor 1. Among the naphthalene isomerization maturation parameters a certain hierarchy was also observed, which depended on whether the parameters represented isomer ratios which differed on the position of one or two alkyl groups. General conclusion based on factor analysis is in agreement with theoretical presumptions concerning the transformations of phenanthrene and naphthalene isomers. (c) 2006 Elsevier B.V.

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.
