The process of oil seeps transformation from the Uzon volcano caldera under the influence of hydrous pyrolysis at a temperature of 350 °C in argon and oxygen was investigated. It is shown that carbon and hydrogen isotope type curves (ITC) reflect the processes occurring in organic matter during hydrous pyrolysis in oxidizing and neutral media. The similarity in forms between carbon ITC of the Uzon oil seeps, the Bogachevka oil and biota of hydrothermal sources is revealed. Hydrogen ITCs have a more complex form, apparently associated with exchange processes occurring in hydrothermal water. Based on the conducted studies, it was assumed that on the one hand oil seeps in the Uzon caldera can serve as a source for the formation of Bogachevka oil, and on the other hand, it is possible that the circulating hydrothermal water in the caldera of the Uzon volcano brings to the surface the organic matter of the Bogachevka oil formation.
