| Summary: | The results of analysis trace elements distribution, including REE and PGE, in crude oils of several oil fields of Volga-Urals and West-Siberian oil-gas provinces (either terrigenous or carbonate reservoirs) are discussed in this paper. It is shown that geochemical specialization of the crude oils is different from geochemical specialization of their gum-asphalten fractions. It is established that the concentrations and ratios of trace elements in the crude oils are underwent considerable variations, and often we do not know why. Therefore, these data in many cases do not play indicator or genetic roles. At the same time, we suppose that certain trace element characteristics of the crude oils of several oil deposits may be useful for their discrimination. All of these indicate that classification and creation of “passport system” for the crude oils will be on the order of the day in nearest future. |
