We report here the results of lithogeochemical studies of silt-rich mudstones of the Tyumen, Vasyugan, Georievsk, and Bazhenov formations and sandstones and siltstones confined to the YuV11, YuV12, and YuV2 pay zones within the Vat-Yogan oil field. Chemical analysis was performed to define chemical composition of 370 core samples To detect major and trace elements an X-ray fluorescence method was used. To interpret the results of the study an R-mode factor analysis as well as nomenclatures, classifications and lithogeochemical techniques developed by F. J. Pettyjohn, M. M. Herron, and Ya. E. Yudovich were applied.
