Coalbed methane - Wikipedia
Coalbed methane (CBM or coal-bed methane), [1] coalbed gas, or coal seam gas (CSG [1]) is a form of natural gas extracted from coal beds. [2] In recent decades it has become an important source of energy in United States, Canada, Australia, and other countries.
Coalbed methane: A review - ScienceDirect
2012年11月1日 · Coalbed methane (CBM) forms as either biogenically- or thermogenically-derived gas. The former occurs in ‘under mature’ (< 0.5% vitrinite reflectance) coals and is the result of bacterial conversion of coal into CO 2 or acetate, …
Coal-bed methane now accounts for about 7.5 percent of total natural gas production in the United States. Scientific understanding of, and pro-duction experience with, coal-bed methane are both in the early learning stages.

2024年9月9日 · What is the difference between coalbed methane (CBM) and CMM? CBM refers to methane that is found in and extracted from coal seams. It is formed during the coalification process, which is the transformation of organic plant material into coal.
Coal Bed Methane - an overview | ScienceDirect Topics
Coal Bed Methane (CBM) refers to an unconventional form of natural gas found in coal deposits or seams. It is a clean energy source extracted by drilling wells into coal seams and is used as compressed natural gas for various domestic and industrial purposes.
Coal bed methane - Energy Education
Coal bed methane is methane trapped in underground coal seams. This type of methane can be accessed using drilling techniques similar to those used in the collection of shale gas. In these deposits, the methane is attached to the surface of the coal.
