Inhibitors:
- Environmental impact of extracting coal seam gas - mainly the disposal of water.
- High initial costs.
- Lower gas rates than conventional reservoirs.
- Movement away from fossil fuels - regardless how clean - towards renewable energy sources.
- Low natural gas prices.
Paradigms:
- Brings a new view on previously uneconomical coal deposits. Previously if a coal deposit was uneconomical for mining it was left unexploited; now it is possible to extract gas from the coal bed for a much lower cost than mining.
- Changes the way China thinks about meeting energy requirements.
- Coal is now seen as a reservoir rock as well as a source rock.
- Methane emissions can be reduced profitably in coal mines.
