The 100 Volumetrically Largest U.S. Oil and Gas Fields (12/7/2010) |
The following letter size maps portray the same information by product.

Top 100 U.S. Oil Fields By 2009 Proved Reserves (12/7/2010) |
Top 100 U.S. Gas Fields By 2009 Proved Reserves (12/7/2010) |
The detailed field maps linked below portray the locations, boundaries, names, and either the barrel-of-oil equivalent (BOE) or the liquid hydrocarbon (crude oil plus lease condensate) or the natural gas reserve size classes of the known oil and gas fields in selected geologically defined areas of the U.S. at year-end 2001. Multiple map sheets were required to adequately portray the fields of some areas. Use this
Index of Detailed Field Maps to identify which of the subsequently listed oil and gas field maps you might be interested in viewing. Pursuant to Section 604 of the Energy Policy and Conservation Act, these maps are one product of a joint Department of the Interior, Department of Energy, and Department of Agriculture study of access to oil and gas resources located on Federal onshore lands. The maps conform to that ongoing study's temporal, areal, and technical requirements.
Note that most of the maps are large format (60 inches X 36 inches, for example) and are intended for printing on a wide-bed printer. To clearly view them on your monitor you will have to zoom in and then scroll through the map.
