Geologic Studies of Deep Natural Gas Resources

In 1997, the U. S. Geological Survey published USGS Bulletin 2146, comprising 12 chapters dealing with geologic, geochemical, and assessment issues related to deep gas resources (Dyman and others, 1997). A primary goal of that report was to provide geology-based information that might aid in future improvements to technology for deep gas exploration and development. Chapters of this report represent a continuation of that work. The current work is funded by the U. S. Department of Energy, National Energy Technology Laboratory, Morgantown, W. Va. (contract No. DE-AT26-98FT40032), Gas Technology Institute (GTI), Chicago, Ill. (contract No. 5094-210-3366 through a Cooperative Research and Development Agreement with Advanced Resources International, Arlington, Va.), and the U. S. Geological Survey, Denver, Colo.
