  1. U.S. Shale Gas Resources, Reserves and $$$ John B. Curtis Potential Gas Agency Colorado School of Mines

  2. Location of U.S Shale Gas Plays U.S. Energy Information Agency, March 2010

  3. The Resource Pyramid Conventional Reservoirs: Small Volumes, Easy to Develop Oil Gas Unconventional Reservoirs: Large Volumes, Hard to Develop Improving Technology Tight Oil; Heavy Oil; Bituminous Sands Increasing Product Price Tight Gas Sands; CBM; Gas Shales Huge Volumes, Difficult to Develop Gas Hydrates Oil Shale Province Resource Size (S. Sonnenberg, CSM)

  4. Shale Gas Annual Production and Energy Information Administration (EIA) Forecast EnCana

  5. Targeted Research – $150 Million

  6. Acquisitions – >$50 Billion Source: Trollart.com – Ray Troll

  8. Hydrocarbons From Shale – Never Say Die

  9. Shale Gas Reservoir Mechanisms U.S. DOE

  10. Exploration Considerations • Natural fractures - Friend or Foe? • Facies changes - greater permeability • Kerogen type - I,II,IIS,III • Microbial or thermogenic gas? • Thermal maturation history • MWD - especially w/ gas isotopes

  11. Organic Richness Maturation Thickness Gas-In-Place Productivity Mineralogy Permeability Brittleness Pore Pressure Some Elements of a Successful Shale Gas Play

  12. Potential Supply of Natural Gas in the United States Report of the Potential Gas Committee (December 31, 2008)
