Petroleum potential of the devon's coal deposits of the North-West Pri-Caspy by the example of the Astrakhan vault

The article presents the analysis of the modern condition of the coal’s resource base of the North-West Pri-Caspy by the example of the Astrakhan vault. The moment of the laying of this structure is proved here. The scientific materials on the structure and the composition of the Pre-Cambrian basement are explored due to the geophysical information. The conformity to natural laws of the crystal basement and the sedimentary cover is detailed in this article. The high level of the petroleum potential has a great rating. The prospects of the Visean-Bashkir complex’s deposits on the territory of the Astrakhan vault is estimated due to the whole analysis of the problem. There is the characteristic of the Astrakhan gas-condensate field. There are four segments: the Left Bank, the Imashevsk, the Central-Astrakhan and the Right Bank. The oil inflows are determined in the Serpukhov’s and Bashkir’s layers in the deposits on the number of the wells. The prospects of the petroleum potential of the Kharabalinsky-Elenovskaya elevating zones are substantiated and examined in this article. The general estimation of the promising stock is 186 mln. a tonne of the conventional fuel. There are the results of the drilling dates and the results of the seismic survey. It is allowed to characterize in the details all the incisions at the well. Therefore, the future prospects of the petroleum potential of the Devon-Coal deposits of the North-West Pri-Caspy are associated with the subsalt deep deposits of the Astrakhan vault.
