In recent years, within the oil and gas provinces of the Russian Federation, there has been a downward trend in both the number of newly discovered hydrocarbon deposits and the volume of incremental reserves. In accordance with the energy strategy of the Russian Federation for the period up to 2030, the development of the hydrocarbon potential of the continental shelf of the Arctic seas and northern territories of Russia is called upon to play a stabilizing role in the dynamics of oil and gas production, compensating for its possible decline in traditional oil and gas producing regions of the country. However, the implementation of these projects is associated with large investments in mining and transport infrastructure. Along with this, given the fragility of the Arctic ecosystems, the costs of measures to prevent environmental risks and remediation of territories increase manifold. All these factors greatly reduce profitability and the competitiveness of Arctic projects, transferring in many respects the problem of their implementation from the economic plane to the political one. At the same time, significant resources of oil and gas can still be explored in old oil-producing regions. The study of oil and gas content at great depths (over 4.5 km) is one of such promising directions. On the territory of Russia, purposeful geological exploration work on deeply submerged subsoil horizons has been carried out since the 60s. last century. As a result of the work carried out at depths of over 4.5 km, a number of oil and gas fields were discovered. In this work, based on the materials of the state balance of mineral reserves of the Russian Federation as of 01.01.2020, an analysis of characteristics of hydrocarbon reserves of deep accumulations is presented.
