On July 5, 2025, it was learned from the Shanxi Coalbed Methane Branch of PetroChina Huabei Oilfield that as of July 4, the cumulative gas production of China's largest medium shallow coalbed methane field - Huabei Oilfield Shanxi Qinshui Coalbed Methane Field has exceeded 20 billion cubic meters, becoming the first coalbed methane field in China to reach this milestone. Coalbed methane, commonly known as gas, is an unconventional natural gas resource mainly composed of methane stored in coal seams. The Shanxi Qinshui Coalbed Methane Field of Huabei Oilfield is located in the southeastern part of Shanxi Province, China, with a mining area of over 3000 square kilometers and an estimated coalbed methane resource of up to 600 billion cubic meters. In 2006, after obtaining the coalbed methane mining rights in the Qinshui Basin of Shanxi Province, PetroChina Huabei Oilfield built China's first large-scale coalbed methane field with an annual surface extraction capacity of over 2 billion cubic meters.

The relevant person in charge of Shanxi Coalbed Methane Branch of PetroChina Huabei Oilfield introduced that in recent years, through continuous deepening of geological research and key technological breakthroughs, innovative application of core technologies such as "differentiated fracturing design and dynamic adjustment of multiple coal seams" has successfully achieved the economic and efficient development of complex coal seams in the middle and shallow layers, providing important technical support for China's unconventional natural gas development. The breakthrough in the development of this gas field has multiple meanings: firstly, the cumulative production of 20 billion cubic meters is equivalent to replacing 24 million tons of standard coal, reducing carbon dioxide emissions by about 30 million tons; Secondly, large-scale development has driven local economic development and energy structure adjustment; Finally, its successful experience provides replicable technical solutions for the development of other coalbed methane fields in China. Experts say that this achievement marks a significant breakthrough in China's unconventional natural gas development, which is of great significance for ensuring national energy security and optimizing the energy structure. In the future, with technological progress and increased development efforts, China's coalbed methane industry is expected to achieve greater development.
