II. How is CBM formed
Coalbed methane (CH4) forms in one of two ways. During the earliest stage of coalification (the process that turns plant detritus into coal), biogenic methane is generated as a by-product of bacterial respiration. Aerobic bacteria (those that use oxygen in respiration) first metabolize any free oxygen left in the plant remains and the surrounding sediments. In fresh water
Coalbed methane is a form of natural gas that is trapped within coal seams.
In recent decades it has become an important source of energy in United States, Canada, and other countries.
It is called sweet gas.
Enhanced coal bed methane recovery
is a method of producing additional coalbed methane from source rock.
This technique may be used in conjunction with carbon capture
