New results of the analysis of metal contents in crude oils of the Yarakta, West Ayan, and Atov deposits of the Lena-Tunguska petroleum province (Eastern Siberia) are discussed. Determination of a wide range of trace elements performs by inductively coupled plasma mass spectrometry (ICP-MS) with sample preparation methods including acid digestion and ashing. Comparison with the oil fields of Western Siberia and shelf of Sakhalin shows that the oil fields in Eastern Siberia have low concentrations of most trace elements combined with high values ​​of V/Ni. This is due to a high content of light fractions and water (sapropelic) origin of the organic component. Oil fields in Western Siberia in general distinguished by higher contents of rare earth (REE) and other lithophile elements, and oil fields of Sakhalin – higher Ni, Co, V. The REE spectra of last two provinces have more pronounced positive Eu anomalies. Crude oils of various provinces form a separate field on the diagram V/Ni – V and V/Ni – Ni.
