The purpose of the proposal is that in many countries of the world there are known large and huge deposits of gas existing at coal formations. The analysis of geological and geochemical materials provide the grounds for believing that such deposits are existent near the Tkibuli deposit.

The Tkibuli-Shaori black coal deposit has been studied in quite a detail; 409 wells of 800-1000m have been drilled. The proven reserve of black coal is 281,6 mln tons. Forecasted reserve is about 49,8 mln tons. Significant amount of methane has been absorbed by the cover rocks of coal layers. According to our calculations, in the process of coal metamorphism significant part of methane is separated from the coal layers and displaced in the direction of adjacent structures. Estimated reserve of gas existing in these structures has been calculated using the methods elaborated in the CIMR. In the coal layers it amounts up 10 bln m³ and in the adjacent structures – 60 bln m³. The rich material about petrographic and chemical-technological characteristics of the coal layers, accumulated in the CIMR, processing of which materials allows solution of two problems: 1. Finding out the feasibility of degassing of the coal layers by means of wells; 2. Assessment of the reserve of gas accumulated in the settled complexes of the territory adjacent to the deposit and selection of optimal structures taking the account of their further operation and efficiency.
