Coal Bed Methane

• Natural gas found in most coal deposits
• Similar to natural gas
• Created from buried plant material which was
  converted to coal by the pressure of being
  underground
• When the coal seam is drilled and the water is
  pumped out, the gas begins to flow
• Usually pure or sweet gas and requires little
  processing

3
Problems

• Adds Carbon Dioxide to the atmosphere
• Contaminates drinking water supplies such as
  aquifers
• the industrys biggest problem is managing the
  volume of water, often with a high sodium
  content, that must be extracted before coal-bed
  gas begins to flow
• Can remove water by truck and re-inject into
  spent gas wells but must be kept isolated from
  potential ground water zones
