WTGS Symposium Midland, Texas October 25, 2001 Geoscience Technology for the Coming Gas Economy Scott W. Tinker & Eugene Kim Bureau of Economic GeologyThe University of Texas at Austin
Introduction Energy consumption in the U.S. and the world has shown a very predictable trend of “decarbonization.” Future U.S. energy consumption will be increasingly dominated by natural gas. Research and technology have been there all the way, responding as needed to the forces of supply, price, policy, and efficiency. Basic energy research should focus on advanced characterization for enhanced oil production and advanced fracture, salt, and seismic analysis for natural gas exploration and development.
