Well SX-001 has begun de-watering in preparation for the injection of CO2 into the target coal seam. The current phase of operations will provide baseline data on water and coalbed methane production from the target coal seams no.3 (approximately five meters thick) and no.15 (approximately 6.6 meters thick).
The company also said that the pilot project operations area has been enlarged to five square kilometers, following the success of phase one.
The pilot project is located on CUCBM’s Shizhuang North block in the Qinshui Basin of Shanxi Province, China. The Qinshui Basin is one of the prolific CBM producing regions in China and the coal seams are prospective for ECBM production.
The pilot project has the objectives of confirming the suitability of the coal seams for CO2 sequestration and long term storage while piloting the enhanced production of CBM from the coal seams in which the CO2 is stored. Coal is deemed to have long term storage potential for CO2 because CO2 will preferentially adhere to the coal cleat surface while displacing methane contained in the coal.
The pilot project is an international cooperative venture between Petromin, Enviro Energy International Holdings and CUCBM. The parties will jointly retain the intellectual property developed during the pilot campaign. CUCBM is supported financially in the venture by the China Ministry of Science and Technology.
