Abstract:

Purpose. The study of the thermal maturity of organic matter-rich coal strata of a transition zone between the Dnieper-Donets depression and Donetsk folded structure to assess their gas generation potential and prospects of gas content assessment.

Methodology.The use of mathematical and statistical system for analysis and evaluation of katagenetic and thermal maturity of organic matter. Forecasting oil-gas strata distribution according to contents of organic matter and vitrinite reflectivity of core samples in the study area.

Findings. The thermal maturity of the studied species corresponds to the main phase of gas generation based on application criteria and predictive signs, supplemented by statistical data on vitrinite reflectivity depending on the depth. The most favorable depths for generation and location of unconventional gas reservoirs are defined.

Originality.Relationship between vitrinite reflectivity (R₀) and depth that is described by the logarithmic relationship with the magnitude of the reliability of approximation (R²) greater than 0.8, was defined and substantiated for the area studied.

Practical value.According to the evaluation parameters R₀, by the high thermal maturity of the rocks was established, which are located preferably within the main zone of gas generation. Investigation of the distribution of organic matter content and vitrinite reflectivity values made it possible to identify the most favorable time intervals for the gas generation section within the studied areas. These intervals are considered to be favorable for localization of unconventional gas.
