Group 1: Production Capacity and Growth - The Daji Gas Field has a newly added annual production capacity of approximately 1 billion cubic meters from 37 newly drilled wells this year [3]. - The current average daily production of coalbed methane is 6.8 million cubic meters, representing a year-on-year increase of 50.1% [3]. Group 2: Geological and Technical Aspects - Coalbed methane is a type of unconventional natural gas resource that is either adsorbed or free in deep underground coal seams, typically buried deeper than 1,500 meters [3]. - The Daji Gas Field is China's first large-scale developed coalbed methane field, with an average burial depth of 2,130 meters and proven geological reserves of 300 billion cubic meters [3].
