    Environmental Aspects and Statistical Analysis of Geological Data of Gas Recovery in Surface Degassing Wells

    ENG: The article is devoted to the analysis of the environmental consequences of hydrocarbon production in Donbas, particularly the extraction of coalbed methane. During coal mining, significant amounts of methane accumulate in geological formations, which subsequently migrate to the surface, creating risks for public health and the environment. Since the share of methane emissions and other pollutants in coal-mining regions is significant, it is necessary to study the conditions of methane migration processes and possible ways to reduce its emissions into the Earth’s atmosphere. One of the directions for solving this problem is to increase the efficiency of degassing systems, transportation and utilization of methane. It is known that the Donetsk basin has complex mining and geological conditions. For methane production through surface degassing wells, it is necessary to carry out methods of clogging and intensification of gas release. However, the implementation of these measures in the conditions of Donbas requires improvement. In the opinion of the authors, the solution to this issue is a statistical analysis of geological data of the rock’s composition of wells working horizons and forecasting of methane accumulation areas. Effective monitoring and management of methane emissions is one of the aspects of ensuring a safe ecological state of the air. It was established that statistical analysis by the method of normality of distribution of experimental data according to the Kolmogorov-Smirnov and Shapiro-Wilk criteria generally corresponds to the methodology of research of geological data but does not allow to assess the regularities of the distribution of gas emissions. Therefore, based on obtained results, it is proposed to continue the analysis of wells’ geological data for justification of wave impact parameters on rocks of the working horizon to restore or increase the methane production rate.
