Abstract <p>The Srednebotuobinskoye oil field has long posed a number of questions to researchers, primarily about the stages and conditions of formation of deposits in the Botuobinsky horizon, one of the main horizons of the Vendian period in Eastern Siberia, since it occupies a vast territory within the Nepa–Botuoba anteclise and is characterized by high productivity. The Botuobinsky horizon is of strategic importance for the oil and gas industry of the Russian Federation, since due to the development of fields concentrated raw materials can be provided to the eastern regions of our country and export potential of Russia in the Asia-Pacific region can increase. This work reports on the stages of formation of deposits of the Botuobinsky horizon, as well as a methodological approach based on the method of paleostructural sequences and analysis of the dynamics of structural changes.</p>
