2 Scott W. Tinker, BEG, 2001 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.
