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.

AB  - In order to gain insight into oil transformations which occur during migration, and to contribute to the elucidation of migration mechanisms in water-wet environments, the content and composition of heavy fuel oil from an accidental oil spill near the railway station of Ušće (Kraljevo) was determined in crushed rock samples from various depths and distances from the oil spill. The group composition (saturated hydrocarbons, aromates, NSO-compounds and residue) of heavy fuel oil extracts was determined. n-Alkanes and isoprenoid alkanes, pristane (Pr) and phytane (Phyt), in the saturated hydrocarbon fraction were identified by gas chromatography (GC). X-ray diffraction analysis (XRD) was applied on the inorganic residue in order to determine its mineralogical composition. The observed differences in the group composition (increase in NSO-compounds content with depth and distance), and in the distribution of n-alkanes and isoprenoid alkanes (the shift of the n-alkane-maximum and the shift of Pr/n-C17-and Phyt/n-C18-ratios towards higher values with depth and distance) lead to the conclusion that heavy fuel oil migration through the crushed rock environment occurred in the presence of water by the colloidal micelle mechanism.
