Summary
The 109th Congress may again decide whether to continue to protect the ecosystem
on the coastal plain of the Arctic National Wildlife Refuge (ANWR) or to open it to oil
and gas drilling – with good prospects of finding economically recoverable amounts of
oil. Less certain are the actual amounts of oil and gas to be found, the impacts of
development on world oil prices and on the U.S. economy, including employment —
although recent substantial increases in oil and gas prices tend to boost estimates of
economically recoverable oil.
Tight world oil supplies, crude oil and petroleum product price increases, and the
decline in crude oil production in the “lower 48" states have produced numerous
proposals to expand U.S. oil production or reduce U.S. oil consumption. One of these
proposals, to open the Arctic National Wildlife Refuge to oil and gas development, has
generated considerable controversy over the years.
ANWR: Ecological and Potential Oil Resource
The coastal plain of Alaska just east of present sites of oil production is the virtually
undisturbed home to a wide variety of plants and animals; several species there are
protected by international treaties or agreements. This “1002 Area” is part of the Arctic
National Wildlife Refuge, which was created in 1960. The Refuge was expanded and
made off-limits to oil and gas development in 1980 explicitly to conserve “fish and
wildlife populations and habitats in their natural diversity" and for other purposes.
ANWR also is a promising U.S. oil prospect. Seismic studies and drilling outside the
restricted area have led to estimates of a good chance of finding significant quantities of
economically recoverable oil.2

A Contingency Tree
The oil market and economic impacts of ANWR oil development would depend
upon the amount of oil discovered, the sizes of the individual fields, the response of the
world oil market to the discovery, the amount of oil eventually produced, the state of the
U.S. economy, and the effects of additional U.S. oil production and any change in world
oil prices. The response of the world oil market and the economic impact would be
contingent upon the unknown and uncertain outcomes of the above factors.
Possible ANWR Volumes and Development Costs
Major determinants of the cost of developing oil fields in ANWR would be the total
amount of oil discovered that would be economically recovered and the sizes of the
individual discoveries. There are high degrees of uncertainty in both areas. The latest
geologic assessment (1998) by the U.S. Geological Survey (USGS) estimated that there
is a 95% chance that there are at least 4.3 billion barrels (bbls) and a 5% chance there are
at least 11.8 billion bbls of technically recoverable oil (recoverable with current
technology, but ignoring costs) in the restricted area, with a mean estimate of 7.7 billion
bbls.3 Estimated economically recoverable amounts are considerably smaller. USGS’s
latest economic assessment found that, if the price of crude oil is $55 per barrel (2003
dollars), there is a 95% chance of at least 3.90 billion bbls and a 5% chance of at least
10.74 billion bbls of economically recoverable oil in the 1002 Area, with a mean estimate
of 7.14 billion bbls.4 These estimates reflect field development practices introduced and
cost and price changes since U.S.G.S.’s 1998 assessment. Quantity estimates increase
with higher prices and decrease with lower prices, but increments of increase decrease as
assumed prices rise.
The USGS estimates also have very wide ranges with respect to oil field sizes.
Among the larger sizes, which oil companies probably would consider first, the estimates
show a 95% chance of three or more fields and a 5% chance of six or more fields with
256-512 million bbls of technically recoverable oil; a 5% chance of four or more fields
and a 95% chance of one or more fields with 512-1,024 million; and a 5% chance of 1½
fields or more and a 95% chance of 0.3 fields or more with 1,024-2,048 million bbls.5
During the exploratory phase, each company would have data, and then would select the
most promising areas based upon its own interpretation of geologic data, its own resource
assessment, and its own financial criteria. As exploration and development progress,
smaller fields probably would become attractive if and when infrastructure is in place.
Thus, given that the sizes both of a possible overall discovery and of individual fields
are unknown, all estimations of the overall cost of developing ANWR are hypothetical.

Two illustrative hypothetical cases might be as follows: (1) The existence of 3.9
billion bbls of economically recoverable oil in seven 100-million bbl fields, six 200-
million-bbl fields, three 375-million-bbl fields, and one 750-million-bbl field. (2) The
existence of 10.74 billion bbls of economically recoverable oil in ten 200-million-bbl
fields, six 375-million-bbl fields, four 750-million-bbl fields, and two 1,500-million-bbl
fields.6 These cases are based upon the previously-described 95% probability and the 5%
probability of economically recoverable oil at $55 per barrel (2003 prices).
Advances in Arctic oil development technology, equipment, and configuration of
facilities reduce both the surface footprint and the development cost per barrel of
discovery.7 These advances have made development more capital intensive onsite but
more labor intensive offsite, mainly performing data analysis. A very crude benchmark
to use for estimating the outlays that would be entailed could be the $1 billion reported
to be the cost of constructing the Alpine field, which has about 430 million bbls of
reserves. Alpine is a recently developed field on the Alaskan North Slope that employs
advanced Arctic technologies. However, Alpine is appropriate as a cost benchmark only
to the extent that the geological conditions, accessibility of the hypothetically discovered
fields, and a variety of other factors in the Refuge are similar to those at Alpine, all of
which adds another dimension of uncertainty to this hypothetical formulation.
If, hypothetically, the fields associated with an overall 3.90-billion-bbl discovery of
economically recoverable oil are of the same nature and degree of difficulty to develop
as Alpine, and if, as is unlikely, development costs are proportional to field size (using
Alpine as the benchmark), and if it is assumed that the Alpine development cost was $1
billion, total development cost of a 3.90 billion bbl discovery would approximate $9.4
billion. If, hypothetically, fields associated with a 10.74-billion-bbl overall discovery are
of the same nature and degree of difficulty to develop as Alpine, and if, as is unlikely,
development costs are proportional to field size, total development cost of that overall
discovery would approximate $26.9 billion.8
At roughly $2.40 and $2.50 per barrel of economically recoverable reserves, the
hypothetical estimate totals (which exclude exploration costs) appear low for Arctic
conditions, and low even compared with overall U.S. averages. In 2001-2003, major U.S.
oil companies experienced U.S. onshore finding costs of $9.35 per barrel (with
exploration costs accounting for about one-third), based upon EIA surveys.9 However,
because the extent to which the developer of Alpine may have included exploration costs
in the $1 billion is not known (cost accounting differs by company), that figure may be

Gas Potential of the Arctic National Wildlife Refuge 1002 Area, Alaska, 1999, Chapter EA.

Arctic, see CRS Report RL31022, Arctic Petroleum Technology Developments.
8 Using a ratio of $1 billion per 400-million-bbl field, the arithmetic is as follows. For 3.90
billion bbls: (7 x $250 million) + (6 x $500 million) + (3 x $937 million) + (1 x $1,875 million)
= about $9.4 billion. For 10.81 billion bbls: (5 x $250 million) + (10 x $500 million) + (6 x $937
million) + (4 x $1,875 million) + (2 x $3,750 million) = about $26.9 billion.

too low for the purpose of estimating hypothetical ANWR development outlays.
Moreover, additional infrastructure would be required if fields are distant from existing
staging areas, including a pipeline to the Trans Alaska Pipeline System.
Oil Market Response
Other things being equal, an increase in supply would be expected to result in a price
decline (or a lower price than would occur otherwise). The size of price decrease would
depend to some extent upon how close world oil output would be in relation to world
production capacity and upon the reaction of other suppliers to the world oil market.
CRS estimates – again, based on hypothetical and uncertain scenarios – that peak
plateau production from economically recoverable volumes of 3.90 billion and 10.74
billion bbls (based upon $55 per barrel in 2003 dollars, or about $58 in 2005 dollars)
would range from roughly 0.4 million to 1.6 million bbls per day, assuming pipeline
capacity imposes no constraints. Production could begin within 10 years, and could last
at least 30 years, declining from the peak. If exploration starts in 2006, peak production
levels probably would be reached in about 2025. EIA projects world oil production to
total 118.9 million bbls per day in 2025.10 On the basis of the aforementioned scenarios,
ANWR production (from the respective discovery volumes) at their peaks around 2020
would range from about 0.3% to 1.3% of world output projected by EIA.
If supply in the world oil market is tight in 2025 and the market reasonably
competitive, 1.6 million bbls per day of ANWR production could result in lower world
oil prices in the short run. OPEC and other producers, however, may cut output sooner
or later to offset the supply effect, as has occurred before. For example, OPEC reduced
production volumes three times in 2001 in response to falling oil prices.
U.S. Economic Effects
Development of ANWR for oil production could affect the U.S. economy directly
through new economic activity generated by the development and production itself,
indirectly through the ripple effect of such activity, indirectly through the effects of any
change in oil prices, and indirectly through any effects on the amount spent to import oil.
A key factor would be the unpredictable state of the economy.
Hypothetical outlays of $9.4 billion and $26.9 billion with an income multiplier of
two applying to them would come to 0.05% and 0.15% of projected Gross Domestic
Product (GDP) in current dollars for the year 2025, assuming for simplicity that all the
outlays occur in one year.11 If the outlays are spread over more than one year, the impact
in each year would be less, but the total effect would be about the same. If there is some
spare capacity, the oil and gas producing industry and its suppliers would benefit.
However, if the economy is at full employment, the multiplier effect would be transitory.

Outlays of similar magnitudes in 2025, when the economy is projected to be about 80%
larger than in 2005,12 would have much smaller relative effects.13 Impacts on some
geographic regions and industrial sectors — Alaska, oil producers, and manufacturers of
drill pipe — would be greater, but some smaller. In analyzing the impact of changes in
energy costs on the economy as a whole or on individual sectors, it is worth noting that
the relative price of oil has decreased since the oil price spikes of the 1970s and early
1980s.14 Energy use per unit of output has fallen, the shares of production costs
accounted for by energy have dropped across the economy with relatively few exceptions,
and energy costs as a share of GDP have declined.
It appears also that any price effect would have to be large and sustained for the
effects to be substantial on a macroeconomic scale. The Organization for Economic
Cooperation and Development (OECD) estimated that a rise in oil prices of $15 per barrel
would cause U.S. GDP to be lower by 0.45% and 0.55% in the first and second years after
the shock.15 The price effect of a 1.3% addition to world oil supply resulting from ANWR
production probably would be modest and temporary, but the macroeconomic result of
a price decline may not be proportional.
Employment Effects. Oil and gas development in ANWR would generate
additional jobs in the national economy to the extent that development results directly and
indirectly in a net economic stimulus. A key factor is whether the economy would be at
less than full employment. The direct effects are less uncertain than the indirect, given
the uncertainty of the effects of ANWR oil on world oil prices and any consequent
beneficial effects of lower energy prices on the economy as a whole.
Order of magnitude estimates can be made for jobs generated by the hypothetical
development outlays by using the national averages of 5.73 jobs directly and indirectly
“required” per $1 million of sales by oil and gas producers as estimated by the Bureau of
Labor Statistics (BLS), and 16 jobs per $1 million of sales by oil and gas field service
companies, as estimated by the author based upon historical data.16 Adjusting for price
increases since 1996 and assuming that each of the above groups accounts for half of the
outlays, it can be estimated that $9.4 billion would lead hypothetically to about 86,000
jobs, and that $26.9 billion would lead hypothetically to about 245,000 jobs.17

13 Changes in investment spending have a magnified effect on the economy from the ripple effects
on the income and spending of other businesses and of households. Income multiplier is the term
used to denote the total impact of the initial spending. Multipliers differ by the sector of the
economy in which the investment takes place. A multiplier of two is reasonable for the type of
spending discussed here.

CRS-6
In contrast, a 1990 report by The WEFA Group estimated that the economic impact
of oil development in ANWR would result in a net gain in employment of 735,000 in the
peak year of job creation.18 Much of WEFA’s job gain results from estimated large
beneficial macroeconomic effects of lower world oil prices that are based partly upon its
assumption that the amount of ANWR economically recoverable oil would be near the
high end of 1987 ANWR resource estimates.19 These differences in estimates of job
generation illustrate the importance of the role played by macroeconomic relationships
and other assumptions used in making such estimates.
The impact of ANWR development on employment would be affected by the
continually changing overall state of the economy. In the long run, the unemployment
rate is determined by the structure of the labor market; and, at full employment, jobs
generated by ANWR development would come at the expense of an approximately equal
number of jobs taken from the rest of the economy.
The effect of ANWR oil on world oil prices would be uncertain, and any price drop
would have to be large and sustained for the macroeconomic effects to be reasonably
noticeable. Any employment gain from beneficial macroeconomic effects of a drop in oil
prices may be offset by harm to oil producers not participating in ANWR development,
who may reduce their operations and workforce, other things being equal; their suppliers
and local economies may be affected as well.
Import Effect. As the U.S. marginal source of petroleum, net imports would be
reduced by virtually one barrel for every barrel of ANWR output. The economy would
benefit temporarily through a reduction in its oil import bill and in the income transferred
overseas to pay for the oil. Using EIA’s crude oil price projection for 2025 of foreign
crude oil of $54 per barrel and assuming mid-range ANWR output of one million bbls per
day, the oil import bill would be cut by $19.7 billion in that year, improving the U.S.
merchandise trade balance in the very short run. However, the relative fall in dollars
flowing abroad could cause the dollar to appreciate, which would tend to reduce U.S.
exports of other goods and services and expand imports to some extent, reversing some
of the initial improvement. Should ANWR oil lower oil prices, a consequent increase in
economic activity may further increase U.S. imports of other goods and services. The
trade deficit basically reflects the desire of Americans to borrow abroad versus the desire
of foreigners to invest or borrow in the United States.
