Today, the urgent problem in many countries is the need to develop a fuel and energy complex through the development of unconventional sources of hydrocarbon raw materials. One of such non-traditional sources of energy is coal bed methane (CBM) - environmentally friendly and efficient, energy and chemical raw materials, the global capacities of which are valued at 260 trillion m3, with significant resources concentrated in the CIS countries (more than 50%). For the Republic of Kazakhstan, the production of coal methane and its use is a potential solution to the problem of gas distribution to northern Kazakhstan. This article discusses the issues of assessing methane-rich zones in coal seams, analyzes the prospects for methane production in one of the sections of the Karaganda coal basin. The purpose of the work is to determine the largest accumulation of gas in the territory of the Taldykuduk site. As a result, a three-dimensional geological model was built, on which basis a map of effective coal-bearing thicknesses was obtained. Volumes of methane gas have a direct correlation with the capacity coal thicknesses. A promising area for methane production is the area within the fault No. 2 and the Northern Taldykuduk fault.
