  1. 4th AMGP/AAPG International Conference Veracruz, Mexico Invited Address: November 6, 2001 Fractures, Salt, Seismic and Ice: Exploiting New Technologies for America’s Natural Gas Energy Future Scott W. Tinker Bureau of Economic GeologyThe University of Texas at Austin

  2. Acknowledgments • AMGP/AAPG • BEG Scientists and Staff • Dr. Eugene M. Kim

  3. Session Themes • Natural Gas Future • Importance of Seismic • Unconventional Sources • Unconventional Approaches • Thin beds • Anomalous pressure • Geochemistry • Rocks

  4. Three Main Points Energy consumption in the United States and the world has followed a very predictable “decarbonization” trend. North American energy demand will be increasingly satisfied by natural gas. Deep water and unconventional sources of natural gas will be major production components, and the southwest United States and Mexico will play a dominant role. Research and technology such as fracture characterization and modeling, advanced seismic analysis, and salt modeling and prediction will improve exploration and development success in the Gulf of Mexico and for unconventional natural gas.
