How to solve the technical problems in CBM development: A case study of a CBM gas reservoir in the southern Qinshui Basin

Current status, challenges, and policy suggestions for coalbed methane industry development in China: A review

“…There is no authoritative data, which makes it difficult for the government to manage the CBM industry on a macroeconomic scale. How to reasonably arrange the property rights of CBM resources, how to achieve the optimal allocation of resources, and how to effectively manage the CBM resources to ensure the orderly implementation of CBM projects have become the primary issues facing the CBM industry in China …”

“…How to reasonably arrange the property rights of CBM resources, how to achieve the optimal allocation of resources, and how to effectively manage the CBM resources to ensure the orderly implementation of CBM projects have become the primary issues facing the CBM industry in China. 39,74,75 Since the 1990s, China has established a number of CBM development companies. These companies have done much work to extend the external cooperation, self-exploration and development of local CBM, develop theory and technologies on CBM exploration and development and formulate standards and regulations, etc Active and effective work has laid a good foundation for the large-scale commercial development and utilization of CBM.…”

Dual diagnostic method for fracture morphology of thermal coalbed methane reservoir

“…The average depth of the 39 layer in 11 well is 650 m, use active water in the whole process, the total amount is 1215 m 3 , quartz sand is 52 m 3…”

“…However, the low average single well output has become a major bottleneck for the development of thermal CBM industry in China. Therefore, how to increase the single well output and improve the development benefit is a technical issue which needs to be unraveled for the sound development of CBM industry of China [3].…”

“…the total amount is 794.5 m3 , quartz sand is 56 m3 , sand ratio is 15.9%, working pressure is during 17.67-19.77 MPa, No. obvious rupture pressure, sand displacement is 8.5 m 3 per minute.…”
