The main aspects for outlining the thematic studies and the scope of exploration of unconventional gas sources deal with potential tight gas reservoirs in Upper Carboniferous and Lower Permian anticlines of Dnieper-Donets Depression. Based on the study’s results, there is provided grounding for presence of gas deposits in the structures that are currently considered to be lacking prospects. Described the role of underlying (gas producing) and overlying (cap) rocks. Explained the ways of gas migration within producing fields and their effect on reserves adjustment in time. Provided the list of potential prospective zones for outlining the thematic studies and the scope of exploration of tight hydrocarbons.
