WebJul 22, 2012 · Biogenic coal-bed methane may be further classified as primary- or secondary-biogenic coal-bed methane. Primary biogenic CBM is generated early in the coal formation process with organic matter in very low rank coal (R o < 0.3 %). Secondary biogenic CBM is formed in coal of low to medium rank seams (0.3–1.5 %, R o) due WebNov 14, 2024 · Coalbed methane (CBM, also natural gas from coal/NGC, or coal seam gas/CSG) is natural gas inherently from and dependent on coal (after Flores 1998; Golding et al. 2010 ). Coal is more fully characterized than CBM itself, as coal is the source substrate for both thermogenic and microbial or biological gas generation of CBM.
