The results of a geoinformation analysis of the geographical features of the placement of metal-enriched oil from the Bazhenov formation of the West Siberian oil and gas basin are presented. The oil of the Bazhenov formation is difficult to recover, hydraulic fracturing technology is recognized as promising for its development, but dangerous to the environment, and the increased content of heavy metals in the oil exacerbates environmental risks. When developing such oil, there is a danger of heavy metals (for example, vanadium and nickel) entering the natural environment during its extraction, transportation and processing. An array of 68 oil samples from 33 fields in the West Siberian basin was used to analyze metalliferous Bazhenov oil. Using information from the database of the Institute of Petroleum Chemistry of the Siberian Branch of the Russian Academy of Sciences and methods of statistical and spatial analysis, the patterns of the conditions of occurrence of metalliferous oil and its physico-chemical properties have been established. The reservoir parameters characterizing the filtration and capacitance properties of the deposits are determined. Deposits of the Bazhenov formation with high and medium concentrations of vanadium and nickel have been identified. The results of the study can be used in the development of new and improvement of existing methods and technologies for the extraction and processing of metalliferous oils, taking into account the environmental consequences.
