Oil and gas resource estimates for frontier outer continental shelf basins were expressed as field-size distributions. A list of AAPG basins was prepared to include field-level information on "original reserves" (reserves plus cumulative production) for oil and gas based on data from files maintained by the U.S. Energy Information Administration and the University of Oklahoma Petroleum Data System. Various distributions, including the 2-parameter lognormal distribution, were fit to each of the basins. In addition, basin-wide geologic characteristics were assigned to each basin. The research analyzed the statistical linkage between the fitted distributions and the geologic characteristics so that inferences could be made about the appropriate parameters for the field-size istributions in the basins to be evaluated.
