“…In this case, the data on the values of total sulfur, paraffin wax, resins and asphaltenes contents averaged by the territory of oilbearing basins of Eurasia were used. Some results of this analysis were given in [6,7]. Below are general regularities of geographic distribution of Eurasian oils Similar regularities are observed [6,7] when studying the spatial variability of total content of asphaltenes and resins (AR content) in Eurasian oils.…”

“…Some results of this analysis were given in [6,7]. Below are general regularities of geographic distribution of Eurasian oils Similar regularities are observed [6,7] when studying the spatial variability of total content of asphaltenes and resins (AR content) in Eurasian oils. As it was shown by the results, the oils of South Asia and the oils on almost all the territory of Siberia and Far East are low-resin.…”

The study of relationships governing the variability of chemical composition of the Eurasian oils has been carried out on the basis of the statistical processing of the data on contents of total sulfur, resins, paraffin wax and asphaltenes in oils. These indices are considered as the principal chemicals of oils chemical composition. The data processed for Eurasian continent was chosen from database on petroleum chemistry, which is create by Institute of Petroleum Chemistry of Siberian Branch of Russian Academy of Sciences and nowadays includes more than 9,000 entries of oil physical-chemical data on all main world oil-bearing basins. Latitudinal and longitudinal dependencies of the above indices of oils chemical composition were studied by methods of statistical and cluster analyses and means of geographical information system (GIS) ArcView 3.1. The results of these studies are represented on the computer maps. It is shown that properties of oils are statistically inhomogeneous in Eurasia depending on geographic position. In average, contents of total sulfur, resins and asphaltenes in crude oil increase in direction from east to west. But the analysis doesn’t reveal longitudinal dependence of paraffin content, only a latitudinal dependence. In average, paraffin wax content in oils increases in direction from north to south. From the analysis of the results of geozoning of oil-bearing territories using the whole complex of indices, the zones of oils that are homogenous by their properties was revealed. The results obtained may be used to solve the problems of a rational use of hydrocarbon resources, in particular: a) siting the oil-refining and petrochemical enterprises, b) developing the regional nets of a rational transporting of hydrocarbons and petroleum products.

“…Petroleum-bearing reservoir rocks occur at a wide range of subsurface depths and are of widely-varying ages (e.g. Tissot and Welte, 1984;Polichtchouk et al, 2001). Liquid hydrocarbons are formed by a complex of processes accompanying the catagenetic transformation of buried sedimentary organic matter (Tissot and Welte, 1984).…”

The sulphur, paraffin, resin and asphaltene contents of over 7,100 Cenozoic, Mesozoic and Palaeozoic oils were analysed and were tentatively correlated with reservoir rock age. The data came from 90 oil‐bearing basins worldwide. Oil compositions appear to show cyclical changes throughout the Phanerozoic, and these changes can be related to orogenic cycles and marine transgressions and regressions.
