Prospects of reveal of considerable deposits of gas on big depths in Dnipro and Donetsk cavity

Abstract

The new data on the geological structure and gas content of the Visean stage lower section – XIIa microfaunal horizon (MFH) were provided. In the central near-axial zones of the Dnipro-Donets basin (DDB) on the sides of Sribnensk and Zhdanivsk depressions they were considered as a main reservoir objective to increase proven reserves of hydrocarbons. The lithofacies analysis of sediments of the MFH section XIIa was given made attempts of back stripping conditions of sedimentation in the zonal plan. The discovery potential of deep reserves of natural gas was shown by the example of the Komyshniansk gas condensate reservoir as the primary object for oil reconnaissance.
