The article explores the prospects for methane extraction at the Taldykuduk and Saran sections of the Karaganda coal basin. It highlights the geological features of these areas, including tectonic structures and varying gas-bearing parameters. Drilling methods, such as vertical drilling with hydraulic fracturing and directional horizontal drilling, are described along with their applicability under specific conditions. The emphasis is placed on the necessity of systematizing and updating geological data, as existing information on the permeability and gas saturation of coal seams is fragmented. The study underscores the critical role of investigating the physical and mechanical properties of coal and conducting additional isothermal desorption tests to evaluate the critical desorption point. The high potential for methane production at significant depths, where gas content reaches 20 m³/t or more, is noted, making these sections attractive for pilot project implementation. The combination of hydraulic fracturing and horizontal drilling methods is recommended to enhance productivity in low-permeability conditions. The article provides conclusions and recommendations for designing drilling operations, emphasizing the need for advanced technologies and the involvement of skilled professionals. It underscores the importance of an integrated approach to studying and developing coalbed methane in the Karaganda basin to achieve sustainable gas extraction
