3. field locationThe site is located in Bukhar-zhyrau district 22 km away from Karaganda city. In the center of the site there is a village Taldykuduk. Power lines and paved roads cross the site.ZhezkazganKarazhalTaldykuduk siteKARAGANDABalhash

4. Work done4 exploration wells with depth from 350 to 881 m with hydraulic fracturing of productive coal beds3 pilot wells (1 directional and 2 vertical wells with thickening of 3 coal beds)Experimental drilling by air hammer method up to 600 m2 wells with plasma-impulse impact on coal seams6 exploration wells with coring

6. Planned workThe methane inflow obtained during the development of wells is about 1,5-2 thous. m3/dayIt is planned to drill 10 exploration wells with coring and 6 production wells, including intersection wells, multilateral wells with hydraulic fracturing

7. Comparative indicators of coal seams gas contentComparison of obtained Karaganda basin isotherm curves with other curves of coal basins of the world. As can be seen from the graph, San Juan and Arkomskogo basins (USA) show the greatest similarity to the Karaganda coal basin. This gives reason to believe that the coal basins are characterized by the similarity in respect of thermal maturity, moisture capacity, ash content, composition of macerals, geological history and possibly reservoir properties

13. SITE LOCATION PLAN

14. EQUIPMENT AVAILABILITYAs the world practice shows, the success of projects for the extraction of coalbed methane depends on the availability of modern technological equipment. In this regard, drilling at the Taldykuduk site conducted using modern drilling rigs «Atlas Copco» of the last generation to accurately drill vertical and horizontal wells or wells with numerous take-off points and hydraulic fracturing fleet:Pump assembly – 3 units;Control station – 1 unit;Blender – 1 unit;Manifold skid – 1 unit;Sand truck – 2 units.

15. partnersIn the management of JSC "KazTransGas" is a huge gas transportation system, which includes more than 30 thousand kilometers of gas distribution networks, more than 15 thousand kilometers of main gas pipelines, 56 compressor stations that have installed 316 gas compressor units, 3 underground gas storage. The company supplies commercial gas over 7 million customers in the country. Trouble proof and trouble-free operations of the whole system provides more than 14 thousand people.

16. INNOVATIVENESS OF THE PROJECTInnovativeness of the project is in the creation of a new energy industry with the use of alternative energy sources. The development of coal bed methane extraction and utilization projects will allow to obtain the following results:development of unconventional non-polluting energy source, which partially replaces the traditionally used coal in the industrialized Central and Eastern Kazakhstan;use of methane as a source of energy in the domestic household and in road transport, where it will replace less environmentally friendly and more expensive liquid hydrocarbons and liquefied gas;development of new industries based on the processing of methane, with the creation of new jobs;reduction of methane emissions, which is the second most important "greenhouse gases“ emitted in the atmosphere by coal mining companies in Central Kazakhstan;Economic costs reduction of the subsequent coal production, improvement of the safety in the operations of the underground coal mining.
