EPCA Phase II Report
Press Release | Comparison Table (PDF)
| Qs and As (PDF)
This report, titled Scientific Inventory of Onshore Federal Lands' Oil
and Gas Resources and the Extent and Nature of Restrictions or Impediments
to Their Development —
Phase II Cumulative Inventory, supersedes Phase I of the inventory.
The report includes:
- All five of the
areas covered by the initial release of the inventory in 2003 (Paradox/San
Juan, Uinta-Piceance, Greater Green River, and Powder River Basins
and the Montana Thrust Belt)
- Six additional areas:
Northern Alaska (the National Petroleum Reserve - Alaska and the Arctic
National Wildlife Refuge 1002 area only), the Wyoming Thrust Belt, the
Denver, Appalachian, and Black Warrior Basins, and the Florida Peninsula
- The additional impact of drilling permit conditions of
approval, as required by Section 364 of the Energy Policy Act of 2005
These 11 areas encompass 99 million acres of Federal lands
and contain an estimated 21 billion barrels of oil and 187 trillion cubic
feet of natural gas, or an estimated 76 percent of the oil and gas resources
under Federal onshore ownership. The report provides an inventory of the
extent and nature of limitations to development of these resources and does
not make any policy recommendations in response to its findings.
The EPCA Phase II report is available in low resolution (72dpi) and
high resolution (300dpi)
If you would like a DVD of the report, please send your name, address

Appendix 11 - Federal Oil & Gas Surface
Management Prescriptions (744MB
This appendix contains the text of stipulations applicable to the Phase
II inventory. Note that only the pages of the land use plans that contain
stipulations used in the inventory are reproduced. The stipulations used are
annotated with an EPCA code, e.g., [EPCA Code: UFSashley003] for a stipulation
in the Ashley National Forest. Note also that the various jurisdictions are
presented by study area. They are presented only once in the study area in
which they dominantly occur even though they may be present in more than one.
Text-only PDF versions of these documents are also available:
(all files below are in .zip format)
This zip file contains personal geodatabase
files (.mdb), layer files (.lyr), and ArcMap GIS Project files (.mxd) suitable
for users of ESRI’s ArcMap GIS. The data for each study area covered
in this release are contained in their own geodatabase files and accompanying
project files. The “Basemap Data.mdb” file contains themes
common to all eleven of the study areas such as state lines, BLM Field Office
jurisdictional boundaries, and National Forest and Grassland boundaries. Therefore
it must accompany any study area files moved or copied to another location.
e00 Files (963MB)
This zip file contains ArcInfo Coverage Export
files that can be imported into a number of GIS software systems. Subfolders
are organized by Phase II study area and contain files broken up by Federal
agency, agency jurisdictional, or land use planning area. For example,
in the “(1) Northern Alaska” subfolder, the “akanwr.e00” file
contains the data for the Arctic National Wildlife Refuge.
Detailed Spreadsheets (925KB)
This zip file contains Microsoft
Excel files that present a more detailed breakdown of the land access categorization
than is contained in the published report. Various tabs within each file
contain tables and charts also found in the report, a quality control evaluation,
and breakdowns by Federal agency, agency jurisdictional, or land use planning
area. The last tabs show summary information for BLM lands and National
Forests and Grasslands within that particular study area.
EIA Proved Reserves Shapefiles (22.9MB)
This zip file contains a pair
of shapefiles for each of the study areas, one showing the oil and gas field
outlines cut against federal land ownership (Fedflds) and field outlines for
all lands (Grossflds). Four of the original EPCA Phase I basins (Powder River,
Green River, Uinta-Piceance, and San Juan/Paradox Basins) are combined into shapefiles
named EPCA1_4basins_fed and EPCA1_4basins_gross. These shapefiles are the result
of the procedures detailed in Appendix 8 of the report.
