From humble beginnings as a coal mine degasification and safety technique developed in the USA during the 1970’s, CBM production is commercially well established in several countries. Global CBM production totals 5.8 Bcfd from 15 basins in the USA, Canada, Australia, China, and India. Interestingly, successful CBM production is occurring from a wide range of coal types, ages, and geologic settings. However, in all cases the keys to commercial success are favorable geologic conditions (good coal thickness, gas content/saturation, permeability). CBM production in China is struggling due to more challenging geologic conditions and non-geological constraints. We can’t change the geologic condition, so the analysis of non-geological constraints became the key to the CBM production in China. The presentation from upper and lower level game to analyze the key factors to development of the CBM, at last give the implication for future production.
