  • Coal seam gas, Coalbed methane
    • present in coal seams (may or may not be viable for coal mining)
    • methane adsorbed in the solid matrix of coal
    • in a mine CH 4 is released as coal is excavated
      • explosion risk, asphyxiation risk ( often flared as a waste product)
  • Shale gas
    • natural gas trapped within shale formation
    • low pressure fracturing to release methane
  • Tight gas
    • natural gas trapped in reservoir rocks with low permeability
    • high pressure fracturing to release methane
