The Discovery Of Significant Oil And Gas Fields In The United States Appendixes

The data appendixes included in this volume provide basic background for and supplement the descriptions and analyses presented in "The Discovery of Significant Oil and Gas Fields in the United States," R-2654/1-USGS/DOE, and should be used in conjunction with that volume. Appendix A consists of the significant oil and gas fields data base, the primary source of data for the descriptive analysis of Sections III and IV of the main report. Appendix B provides cumulative and current (1975) production data for crude oil and natural gas by field size class for each state or statistical area and region, supplementing the descriptive analyses of Section III. Appendix C lists the number of significant oil field discoveries in the United States by field size class over 5-year periods by region and type of field, supplementing the figures of Section IV. Appendix D gives data on the amounts of crude oil and natural gas discovered in the United States by 5-year periods up to and including 1975, also supplementing the figures of Section IV. Appendix E presents data on exploratory drilling by region in the United States from 1936 to 1975. Appendix F provides estimates of future significant discoveries in the lower 48 states by field size and region, supplementing the undiscovered resource estimates of Section V. Each appendix is preceded by a brief introduction that describes the tables in that appendix, the procedures used to prepare them, and their sources of data.
