Oil- and gas-related maps, geospatial data, and geospatial software
Maps in Portable Document Format (.pdf)
The following maps were developed using GIS software and then converted to pdf format. You must therefore have the Adobe Reader® browser plugin installed to view them (free download available at Adobe Acrobat Reader). Most of the maps are large format (60 inches X 36 inches, for example) because they were 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. They will also take more than just a couple of seconds to load owing to their complexity.

United States shale gas maps
The following map panels show the drilling history and the natural gas proved reserves, production, and proved ultimate recovery histories of selected low-permeability, self-sourced, continuous-type shale reservoirs. Selected geologic characteristics pertinent to occurrence of producible gas resources in the reservoir are also shown when available.

United States oil and gas field maps
The following national map portrays the location of fields identified as being among the 100 largest oil and/or 100 largest gas fields in the United States on December 31, 2009, per EIA's U.S. Crude Oil, Natural Gas, and Natural Gas Liquids Proved Reserves, 2009.

Detailed oil and gas field maps
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.

Geospatial Data in Shapefile (.shp) Format
Compatible GIS software is required to read, render, and manipulate the data content of the following files that provide the identification, location, boundary, size class, and other EIA-sourced information used to generate the detailed field maps linked above. The files are provided in compressed format (.zip) sets.
      Users of WinZip® are advised that a default setting must be changed in the WinZip compression           utility (any version) to avoid corruption of the GIS files while they are being unzipped. The following       change only affects unzipping:

      1) Open WinZip Classic.

      2) Select Options > Configuration > Miscellaneous tab.

      3) Uncheck the 'TAR file smart CR/LF conversion' box. It will remain unchecked until you check it again.

      4) Select OK.

EIA's oil and gas field Boundary Generation Scripts
The following Word® (.doc) files provide and describe three script codes conceived, developed, and implemented by EIA to (a) automatically and efficiently generate geologically reasonable oil and gas field boundaries from well data, and then (b) calculate the percentage of Federal land within the each field's boundary. The scripts are coded in Visual Basic® for use in conjunction with ArcGIS® software.

Application of the decision procedure specified in the Federal Geographic Data Committee's Guidelines for Providing Appropriate Access to Geospatial Data in Response to Security Concerns to the geospatial data provided via this web page resulted in a finding that safeguarding of these data is unwarranted.
