According to a new Bureau of Land Management (BLM) report, vast untapped oil and natural gas resources exist on public lands in the U.S. These public lands are estimated to contain 31 billion barrels of oil and 231 trillion cubic feet of natural gas, but are are presently closed to energy production.

The new report, known as EPCA III, puts the total figures for energy supplies withheld by the Congress at 117 billion barrels of oil and 651 trillion cubic feet of natural gas. (The U.S. Minerals Management Service (MMS) estimates that America’s outer continental shelf contains nearly 86 billion barrels of oil and 420 trillion cubic feet of natural gas). This is enough oil to replace our OPEC imports for over 50 years, and enough natural gas to supply all US needs for 30 years.

Report Offers Road Map for Energy Relief

With average national gas prices hovering around $4 per gallon, the Bureau of Land Management today released a study that shows vast untapped oil and natural gas resources exist on public lands in the U.S.

“America has abundant energy resources,” said Assistant Secretary of the Interior for Land and Minerals Management C. Stephen Allred. “However, for a variety of reasons, many of these resources are not available for development. At a time when energy prices have reached record levels and Americans are feeling the impact, we must find ways to develop those key energy resources that are available to us right here at home, on our public lands.”

The report is the third in a series of congressionally mandated scientific studies of U.S. onshore Federal oil and natural gas resources and limitations on their development. All onshore Federal lands throughout the U.S. believed to have energy potential are included in this latest study. These public lands are estimated to contain 31 billion barrels of oil and 231 trillion cubic feet of natural gas. The BLM administers leasing of onshore Federal oil and gas resources.

The inventory found that 60 percent of the onshore Federal lands that have potential as domestic sources for natural gas and oil are presently closed to leasing, making 62 percent of the oil and 41 percent of the natural gas inaccessible for development. An additional 30 percent of onshore Federal oil and 49 percent of onshore Federal gas may only be developed subject to restrictions over and above standard environmental lease terms, including seasonal timing limitations. The study found that in the inventory areas just 8 percent of onshore Federal oil and 10 percent of onshore Federal gas are accessible under standard lease terms.

The 279 million acres inventoried are managed by various Federal agencies, including the BLM and other agencies in the Department of the Interior and the U.S. Forest Service, which is part of the Department of Agriculture. Some of these acres are split estate, where the subsurface mineral resources are Federally owned but the surface is privately owned.

“Public lands have a significant role to play in meeting our domestic energy needs securely and affordably,” said BLM Director Jim Caswell. “Current technology allows us to develop energy resources without adversely impacting the environment or permanently diminishing other non-energy resources found on public lands. With the means to make energy development a temporary use of the land, we don’t have to choose between energy security and healthy lands.”

The latest inventory expands on earlier reports published in 2003 and 2006 pursuant to the Energy Policy and Conservation Act of 2000, or EPCA. The Energy Policy Act of 2005 also directed that the EPCA study consider conditions of approval, which are restrictions attached to drilling permits (e.g., no drilling permitted during seasonal migration of sensitive species), and to which companies must adhere during lease development.

The new report was prepared under the direction of the BLM. Co-authors, contributors, and reviewers include the U.S. Geological Survey, the USDA-Forest Service, and the Department of Energy and its Energy Information Administration.

The report and a related fact sheet are also available online at:

The BLM manages more land – 258 million acres – than any other Federal agency. Most of this public land is located in 12 Western states, including Alaska. The Bureau, with a budget of about $1 billion, also administers 700 million acres of sub-surface mineral estate throughout the nation. The BLM’s multiple-use mission is to sustain the health and productivity of the public lands for the use and enjoyment of present and future generations. The Bureau accomplishes this by managing such activities as outdoor recreation, livestock grazing, mineral development, and energy production, and by conserving natural, historical, and cultural resources on the public lands.
