Abstract:
The term natural bitumen used in this paper refers to viscous, viscoplastic, and solid bitumens, which cannot be
extracted by methods commonly used in oil production. For the most part, this is a disregarded reserve of
hydrocarbon resources. The geological development of particular tectonic elements in the Ural-Volga Region is responsible for the specific mechanisms of oil conversion into natural bitumen, which is reflected in their composition and properties.
