Regional geological study of the Volga-Ural oil and gas province subsoil

The long-term regional geological study of the Russian Federation subsoil at the All-Russian Geological Research Institute of A. P. Karpinsky resulted in establishing an original array of geological and cartographic data for the country’s territory, which has geological maps sets of three generations (scales of 1 : 200,000 and 1 : 1,000,000), integrated and review maps of the Russian Federation and its continental shelf (scale of 1 : 2,500,000), including the geological map, deep structure and geophysical anomalies maps, Early and Late Preсambrian maps, etc. This data set located on the Institute’s website as part of the national geological and cartographic resource Digital Twin of Russian Subsoil is a unique record including geological structure of the Volga-Ural oil and gas province, its sedimentary cover stratigraphy, and the region’s tectonic evolution, which the paper describes briefly. The current work on the Volga-Ural region geological mapping, which is aligned with monitoring the State Geological Map (scale of 1 : 1,000,000), involves detailing and updating geological, geochemical, stratigraphic, and other data. The studies aid in connecting geological characteristics of the territory and its oil and gas potential, which enables the region to retain an important role in the Russian oil and gas industry for the long run.
