The majority of China's coalbed methane resources lie in the Qinshui Basin of Shanxi province and the Ordos Basin in the Inner Mongolia autonomous region.
Together, these two basins contain around one-third of China's total coalbed methane volume and 93 percent of discovered geological reserves.
Commercial-scale coalbed methane production in China started more than a decade ago.
In 2017, China National Offshore Oil Corp, the country's largest producer of offshore oil and gas, issued a tender inviting domestic and foreign companies to bid for 10 coalbed methane blocks in the Ningxia Hui autonomous region, and Shanxi, Shandong and Anhui provinces, covering 2,173 square kilometers.
The Shanxi provincial government is toughening up in its management of coalbed methane mining rights to ensure licenses go to capable parties, in order to boost exploration and output.
Coalbed methane (CBM) is a form of natural gas extracted from coal beds.
If the enterprises fail to invest sufficient capital into the exploration, as stipulated in the contracts, their registered coalbed methane blocks will be reduced proportionally.
With years of accumulated tests and experience, the new rules and regulations are largely finalized, according to Lian Bipeng, director of the coalbed methane division of the Shanxi Provincial Natural Resources Department.
