Abstract:
Purpose. To identify potential places of hydrocarbon accumulation in the Black Sea-Caspian Sea region.
Methodology. To achieve this goal, the author used the methods of retrospective analysis, review and comparison. With the help of the retrospective analysis, it became possible to determine that the crustal structures of this region are in close interaction with the border areas and have passed a long geological way of development, but all of them are united by the presence of hydrocarbon accumulations.
Findings. The methods used allowed studying the development of each major element of the Black Sea-Caspian Sea region and making conclusions about the prospects of its oil and gas potential. For example, in the modern structural plan of the Low Kura depression, the local gravitational Navaghi maximum of submeridional stretch was revealed. It emphasizes the relatively shallow occurrence of dense rocks composing the island arc series. It is established that the Georgian part of the Middle Kura depression smoothly passes into the Azerbaijan territory of the Middle Kura depression where terrigenous-carbonate and volcanogenic Meso-Cenozoic deposits are discovered. Small accumulations of oil in thin sand reservoirs of the Eocene were also identified.
Originality. The presented study showed the prospects for the development of oil and gas regions within Western Azerbaijan, since there are found anticline folds, which indicate the old age of origination. This suggests that they had been formed before the migration of hydrocarbons and could be the place of their localization. It is established that in Georgia, the prospects for the discovery of oil and gas fields are associated with Neogene and Paleogene upper-Cretaceous structural floors and access to the Black sea shelf.
Practical value. Analysis of the development of the depression part of the Black Sea-Caspian Sea region allows identifying regions where hydrocarbon accumulation is possible, which is of practical significance.
