Sales of Fossil Fuels Produced from Federal and Indian Lands, FY 

2003 through FY 2013 

Summary 

The U.S. Energy Information Administration (EIA) estimates that total sales of fossil fuels from 

production1

 on federal and Indian lands decreased by 7% during fiscal year2 (FY) 2013. The decrease in 

production on federal lands alone was also 7% (Table 1). Sales from production on Indian lands, which 

account for less than 7% of total federal and Indian lands production, increased by 9% (Table 2). 

Crude oil production on federal lands increased slightly in FY 2013, but that increase was more than 

offset by decreases in coal, natural gas, and natural gas plant liquids (NGPL) production. Other notable 

developments in FY 2013 included the following:

• The continued steady decline of offshore natural gas production in the federal Gulf of Mexico 

(Table 4), a mature area with declining natural gas production from existing fields

• A 9% drop in federal onshore natural gas production, with most of that decrease in Wyoming

• A 9% drop in coal production

Breakdowns by state and area of the fuel production volumes on federal and Indian lands show that:

• Wyoming and the federal Gulf of Mexico together produced 73% of the federal and Indian lands 

fossil fuels total in FY 2013 (Table 6).3

• The federal Gulf of Mexico produced 69% of the federal and Indian lands crude oil total in FY 

2013 (Table 7).

• Wyoming, the federal Gulf of Mexico, New Mexico, and Colorado together represented 86% of 

total production of natural gas on federal and Indian lands in FY 2013 (Table 8).

• Wyoming produced 80% of the federal and Indian lands coal total in FY 2013 (Table 10).

EIA’s estimates are based on data provided by the Department of the Interior’s (DOI) Office of Natural 

Resources Revenue (ONRR) and include sales of production from federal onshore and offshore lands, 

and from Indian lands.4

 EIA summarizes total sales of fossil fuels produced on federal and Indian lands 

in common energy units (British thermal units, or Btu) to allow for aggregation across fuels, including 

crude oil and lease condensate, natural gas, natural gas plant liquids, and coal (Tables 1 and 2). The data 

presented in this paper update data previously reported by EIA5 for FY 2003 through FY 2012.

The sales reported by ONRR are a reasonable proxy for marketed production for a fiscal year. Sales are 

assigned to the fiscal year in which the sales were made rather than when royalties were collected. 

They also include production leaving the lease that is exempt from royalty payments under various 

royalty relief programs.

 1 Throughout this report, the term production means sales from production. 2 The U.S. government’s fiscal year runs from October 1 through September 30. 3 For state-level summaries, ONRR combines Indian and federal lands data to avoid revealing proprietary data. 4 Includes offshore and onshore areas the federal government owns or administers, including American Indian lands. 5 Sales of Fossil Fuels Produced from Federal and Indian Lands, FY 2003 through FY 2012, EIA, May 2013, found at

Includes only those quantities for which the royalties were paid on the basis of the value of the natural gas plant liquids produced. Additional quantities of natural gas plant 

liquids were produced; however, the royalties paid were based on the value of natural gas processed. These latter quantities are included with natural gas.

Notes: Total fossil fuels equals the sum of crude oil and lease condensate, natural gas plant liquids, natural gas, and coal. In addition, the sales volumes are reported for the 

fiscal year in which the sales occurred as opposed to the date of the royalty payment. Volumes include fossil fuels for which royalties were paid, as well as those amounts 

exempt from royalty payments, such as additions to the Strategic Petroleum Reserve.

Btu Data: U.S. Energy Information Administration. Btu are calculated using average, calendar-year heat rates for production of each fossil fuel, as reported in the Monthly Energy 

Review (February 2014). The total Btu-content per fossil fuel is calculated by multiplying the physical data by the approximate heat content. The fossil fuel total is the sum of the 

total heat content for crude oil and lease condensate, natural gas plant liquids, natural gas, and coal.

Percent of Total: Percentages are calculated by dividing sales of production from federal by total U.S. production, then multiplying by 100. Fiscal year values for total U.S. 

production are the sum of October-September values from the Monthly Energy Review (February 2014) and reflect EIA’s current data updates.

Sales from production on federal and Indian lands

Coal represented 51% of fossil fuel sales from production on federal lands in FY 2013, measured in 

common Btu units, followed by natural gas (25%), crude oil (22%), and NGPL (2%). Total fossil fuels 

sales from production on federal lands decreased 7% from 17,230 trillion Btu in FY 2012 to 15,942 

trillion Btu in FY 2013 (Table 1):

• Sales of crude oil6 from federal lands increased 1% to 606 million barrels in FY 2013. A 1% 

decrease in federal offshore volumes was more than offset by a 7% increase in the much smaller 

federal onshore volumes (Table 3). Despite this increase, crude oil production from federal lands 

as a share of total U.S. crude oil production dropped from 26% in FY 2012 to 23% in FY 2013 

(Table 1). This drop in the federal lands share of total production was the result of the 15% 

increase in total U.S. crude oil production, with the continued growth in production of tight oil 

outpacing the modest increase in sales from federal lands.7

• Sales of natural gas from federal lands decreased 10% in FY 2013 to 3,843 billion cubic feet, with 

both offshore (13%) and onshore volumes (9%) declining (Table 4). Natural gas production on 

federal lands dropped to 16% of the U.S. total in FY 2013 from 18% in FY 2012 (Table 1).

• Sales of NGPL produced on federal lands decreased 13% to 103 million barrels in FY 2013, the 

third consecutive decrease since the peak year (FY 2010) over the period FY 2003 to FY 2013 

(Table 5). Nevertheless, FY 2013 NGPL production was at or above levels reported from FY 2003 

through FY 2009. Compared with FY 2012, federal onshore volumes dropped 21% in FY 2013,

while federal offshore volumes were virtually unchanged. 

• Coal sales from production on federal lands decreased by 9% to 401 million short tons in FY 

2013, a 17% decrease from its peak in FY 2008 (Table 1), driven primarily by a decline in 

Wyoming production (Table 10). Coal produced on federal lands accounted for 40% of the U.S. 

total in FY 2013, down from 42% in FY 2012.

Coal represented 42% of fossil fuel sales from production on Indian lands in FY 2013, measured in 

common Btu units, followed by crude oil (29%), natural gas (22%), and NGPL (2%). Total fossil fuels sales 

from production on Indian lands increased 9% from 836 trillion Btu in FY 2012 to 912 trillion Btu in FY 

2013 (Table 2), as an increase in crude oil volumes outpaced a decrease in natural gas volumes:

• Sales of crude oil produced on Indian lands increased a fourth consecutive year, by 48% to 46 

million barrels in FY 2013 (Table 3), the highest level between FY 2003 and FY 2013. 

• Sales of natural gas from Indian lands decreased by 5% to 239 billion cubic feet in FY 2013 (Table 

4).

• Sales of NGPL and coal produced on Indian lands were virtually unchanged at 4 million barrels 

and 19 million short tons, respectively, in FY 2013 (Tables 5 and 6).

Trends in federal and Indian lands production from FY 2003 through FY 2013

Overall fossil fuel production from federal lands generally declined between FY 2003 and FY 2013, down 

21% in FY 2013 compared with FY 2003 (Table 1). This trend is primarily the result of a steady decline in 

federal offshore natural gas production between FY 2003 and FY 2013 and the 9% drop in coal 

production from federal lands in FY 2013 from FY 2012.

• Crude oil production from federal lands decreased 11% between FY 2003 and FY 2013 (Figure 1, 

Table 3). Lower production in the federal Gulf of Mexico over that period led to a decrease in 

federal offshore production of 18%, which outweighed the 33% increase in the much smaller 

federal onshore volumes over the same period.

• Natural gas production from federal lands has declined steadily, down 43% by FY 2013 (Figure 1, 

Table 4). The once-larger federal offshore volumes have declined every year through FY 2013, 

down 74% from FY 2003. That decrease has been only partially offset by the now-larger 

onshore volumes, which have increased 17% over the period. This declining natural gas 

production from federal lands coupled with increasing total U.S. natural gas production8 steadily 

reduced the federal lands share of total U.S. natural gas production (Table 1).

• NGPL production from federal lands increased 11% between FY 2003 and FY 2013 (Figure 1, 

Table 5). Following the natural gas trend, the once-larger federal offshore NGPL volumes have 

declined 14%, while the now-larger onshore NGPL volumes have increased 40% over the period.

• With the notable exceptions of FY 2008 and FY 2013, years of high and low production 

respectively, coal production from federal lands has generally not deviated much from its 

average annual level of 445 million short tons (Table 1). Measured from peak to trough, federal 

land coal volumes declined 17% over FY 2008 to FY 2013. Coal production on private land 

declined 12% over the same period.9

Statistical Information Site” (http://statistics.onrr.gov).

Total fossil fuel production from Indian lands increased each year since FY 2010, although it decreased 

6% between FY 2003 and FY 2013. Rapid increases in oil production partially offset large decreases in 

coal production and smaller decreases in natural gas production between FY 2003 and FY 2013 (Table 2).

• Crude oil production from Indian lands increased 360% from 10 million barrels in FY 2003 to 46 

million barrels in FY 2013. Almost all of this increase took place since FY 2010 (Figure 2, Table 3), 

and mostly in North Dakota (primarily the Fort Berthold Indian Reservation in the western part 

of the state), with the increase in horizontal drilling and fracking and generally higher oil 

prices.10

• Natural gas production and coal production from Indian lands declined between FY 2003 and FY 

2013 by 16% and 37%, respectively. Except for a small deviation in FY 2011, natural gas and coal 

production have steadily declined since FY 2005 (Table 2).

base level (Table 5).

Four agencies—the National Park Service, Fish and Wildlife Service, and Bureau of Land Management 

(BLM), in the Department of the Interior, and the U.S. Forest Service in the Department of Agriculture—

administer about 95% of those federally owned lands.11 ,12 

Most production of fossil fuels from federal and Indian lands falls under purview of the BLM. The BLM 

manages 248 million acres and is responsible for 700 million acres of subsurface mineral resources.13

Federal land ownership is heavily concentrated in 12 western states:

• 62% of Alaska is federally owned.

• 47% of the 11 western states14 in the Lower 48 is federally owned. In calendar year 2012, those 

11 western states represented approximately 20% of total U.S. reserves of crude oil and lease 

condensate and 24% of total U.S. reserves of wet natural gas.15 Wyoming, Montana, Colorado, 

Utah, and New Mexico are the leading states in production of fossil fuels from federal and 

Indian lands. 

• Only 4% of lands in the other states is federally owned.

Indian lands are primarily in the western United States, with concentrations in Arizona; the four corners 

region of Arizona, New Mexico, Colorado, and Utah; North and South Dakota; and a few other states 

(Figure 3).

Figures 4 through 8 provide summary information for production from federal and Indian lands for 

leading states and offshore areas. Complete state-level data on production from federal and Indian 

lands are provided in Tables 6 through 10.16 The relative and absolute contribution of each state and 

offshore region in federal and Indian lands production varies significantly across fuels. Some notable 

observations include: 

• Wyoming and the federal Gulf of Mexico together produced 73% of the federal and Indian lands 

fossil fuels total in FY 2013 (Table 6, Figure 4). New Mexico, Colorado, and Utah were the next 

largest production states.

• The federal Gulf of Mexico produced 69% of the federal and Indian lands crude oil total in FY 

2013 (Figure 5, Table 7). New Mexico, North Dakota, and Wyoming were the next largest crude 

oil producers on federal and Indian lands. Crude oil production on federal and Indian lands 

represents the majority of total (public and private) crude oil production in each of these states: 

New Mexico, Wyoming, and Utah. 17

• Rapidly increasing crude oil production from the Bakken formation lifted federal and Indian 

lands production volumes in North Dakota past corresponding volumes in Wyoming in FY 2013. 

Federal and Indian lands crude oil production in both North Dakota and New Mexico has been 

increasing rapidly in recent years.

• Wyoming, the federal Gulf of Mexico, New Mexico, and Colorado together represented 86% of 

total production of natural gas on federal and Indian lands in FY 2013 (Figure 6, Table 8). The 

federal Gulf of Mexico’s rapidly declining natural gas production fell behind Wyoming by FY 

2012. New Mexico’s federal and Indian production has declined steadily and gradually over FY 

2003 to FY 2013.

• Production of coal on federal and Indian lands is dominated by Wyoming, which accounted for 

80% of the total in FY 2013 (Figure 8, Table 10). Montana, Colorado, Utah, and New Mexico 

were the next biggest coal producers on federal and Indian lands. Production in Wyoming and 

Montana has been declining since FY 2009, reflecting generally declining demand for coal over 

the period.

Data sources

Department of Interior program offices continually collect sales and royalty payment data on fossil fuel 

sales of production from federal and Indian lands. Near the end of the first quarter of each new calendar 

year, ONRR issues the sales data it collected for the previous sales year. Sales are assigned to the fiscal 

year in which they occur, not necessarily the same year royalties were collected. Audits conducted by 

ONNR result in revisions to data previously reported. 

This report is based on information reported to and processed by ONRR as of February 5, 2014, and 

released March 13, 2014. ONRR updates the data values it reports for prior years. The recently-updated 

data provided by ONRR for FY 2003 through FY 2012 generally fall within 2% of the volumes EIA 

reported previously, although updates for some NGPL volumes slightly exceeded that threshold (FY 2010 

and FY 2011 volumes were revised up about 3% and FY 2012 volumes up about 4%).
