Shortages of gasoline, heating oil, and natural gas and concern for the increasing usage of the world’s depletable energy resources have resulted in a proliferation of reserve and resource estimates that almost defy rational analysis. Two recently published estimates of “undiscovered” oil and gas resources of the United States illustrate the problem: (1) the U.S. Geological Survey optimistically estimated (U.S.Dept,of Interior News Release, March 26, 1974) that the United States contains 200- 00 billion bbl of oil and 1,000–2,000 Tcf of natural gas yet to be discovered; (2) Mobil Oil Corporation’s “best” estimate is 88 billion bbl of oil and 443 Tcf of natural gas yet to be discovered in the United States (Gillette, 1974). The pessimistic estimate by Mobil probably represents the view of a majority of major-oil-company exploration personnel. Which of these estimates is correct—if either—is important not only to the petroleum industry but also to the various governmental agencies now conducting long-range energy-resource planning.
In an effort to compare, and perhaps to refine, methods of estimating oil and gas resources, a research conference sponsored by The American Association of Petroleum Geologists (AAPG) was convened at Stanford University August 21- 23, 1974. The conference was attended by 50 government, university, and industry geologists—from the United States, Canada, and France—who have been concerned with petroleum resource estimates for several years (and who are responsible for many of the published estimates). Kenneth H. Crandall was convener of the conference, and John W. Harbaugh arranged the housing, food, and meeting facilities for the participants
