Chapter 2 - Liquid Fuels
World liquids consumption increases from 84 million barrels per day in
2005 to 99 million barrels per day in 2030 in the IEO2008 high price case.
In the reference case, which reflects
a price path that departs significantly
from prices prevailing in the first 8 months of 2008,
liquids use rises
to 113 million barrels per day in 2030. |
The demand for liquid fuels and other petroleum4 increases strongly in
the IEO2008 reference case. World use of liquids grows from 83.6 million
barrels oil equivalent per day5 in 2005 to 95.6 million barrels per day
in 2015 and 112.5 million barrels per day in 2030. Much of the increase
in total liquids consumption is projected for the nations of non-OECD Asia
and the Middle East, where strong economic growth is expected, and nearly
three-quarters is projected for use in the transportation sector.
In addition to the reference case, IEO2008 includes a high price case that
helps to quantify the uncertainty associated with long-term projections
of future oil prices. In the high price case, which reflects a price path
that is closer, in real terms, to prices prevailing during the first 8
months of 2008, world liquids consumption increases by only 0.7 percent
per year on average from 2005 to 2030, as compared with 1.2 percent per
year in the reference case. World liquids use in the high price case totals
99.3 million barrels per day in 2030, as the liquids share of total energy
consumption declines from 37 percent in 2005 to 30 percent in 2030.
To meet the increment in world liquids demand in the IEO2008 reference case,
28 million barrels per day of additional supply will be required by 2030
(Figure 26 and Table 3 ). In the reference case projections, sustained high
world oil prices bolster the economic prospects for development of unconventional
resources and enhanced recovery of conventional resources, as well as for
conventional supplies in OPEC and a number of non-OPEC nations (such as
Kazakhstan and Brazil) with significant potential for development of conventional
resources. Total non-OPEC liquids production in 2030 is projected to be
15 million barrels per day higher than in 2005, representing 53 percent
of the increase in total world production over the 2005 total.
Unconventional resources (including oil sands, extra-heavy oil, biofuels,
coal-to-liquids [CTL], and gas-to-liquids [GTL]) from both OPEC and non-OPEC
sources are expected to become increasingly competitive in the reference
case (Figure 27). World production of unconventional resources, which totaled
only 2.5 million barrels per day in 2005, increases to 9.7 million barrels
per day in 2030, accounting for 9 percent of total world liquids supply
in 2030 on an oil equivalent basis. Biofuels, including ethanol and biodiesel,
will be an increasingly important source of unconventional liquids supplies,
largely because of the growth in U.S. biofuels production. In the IEO2008 reference case, U.S. biofuels production in 2030 is projected to be 1.2
million barrels per day, accounting for nearly one-half of the increase
in world biofuels production over the projection period.
World Liquids Consumption
World liquids consumption in the IEO2008 reference case increases from
84 million barrels per day in 2005 to 113 million barrels per day in 2030,
mainly as a result of increases among the emerging economies of the world,
where strong economic growth is expected throughout the projection period.
Liquids remain the most important fuels for transportation, because there
are few alternatives that can compete widely with liquid fuels. With world
oil prices remaining relatively high through 2030, the increasing cost-competitiveness
of non-liquid fuels causes many stationary uses of liquids (that is, for
electric power generation and for end uses in the industrial and building
sectors) to be replaced by alternative energy sources, which increases
the transportation share of liquids consumption. On a global basis, the
transportation sector accounts for 74 percent of the total projected increase
in liquids use from 2005 to 2030; the industrial sector accounts for virtually
all of the remainder (Figure 28).
Strong expansion of liquids use is projected for the non-OECD countries,
fueled by robust economic growth, burgeoning industrial activity, and rapidly
expanding transportation use. The most robust regional growth in liquids
consumption is projected for non-OECD Asia and the Middle East (Figure
29). In non-OECD Asia, liquids use expands by 16 million barrels per day
over the projection period, from 15.3 million barrels per day in 2005 to
30.8 million barrels per day in 2030. Among the nations of non-OECD Asia,
China and India account for much of the growth in liquids demand, and together
they account for 11.5 million barrels per day (74 percent) of the regional
increment in liquids use. Liquids consumption in non-OECD Asia is projected
to surpass that in the United States (currently the worlds largest liquids-consuming
nation) by 2020, and in 2030 it is projected to exceed U.S. consumption
by nearly 40 percent.
In the Middle East, liquids consumption is projected to increase by 3.6
million barrels per day from 2005 to 2030. Three major factors contribute
to the growth in oil consumption in the Middle East:
- First, although the population in the Middle East is relatively small, the
nations of the region have recorded relatively high birth rates over the
past several decades, so that at present a substantial portion of the population
is young and reaching driving age, increasing the demand for personal motorization
[1].
- Second, energy use is heavily subsidized in many of the resource-rich nations
of the region. In Iran, for example, gasoline prices average $0.42 per
gallon, shielding consumers from the high free-market price of gasoline.
As a result, consumption has continued to increase strongly in Iran, by
an estimated 9 percent per year since 2004 [2].
- Finally, many of the worlds major oil-exporting nations are in the Middle
East, and as world oil prices have continued to rise, so too have their
per-capita incomes. As standards of living have improved, demand for personal
motorization has increased, and many nations of the region have seen double-digit
growth in automobile sales in recent years [3].
In contrast to the non-OECD nations, liquids consumption in the OECD nations
generally grows more slowly, reflecting expectations of slow growth or
declines in population and relatively slow economic growth in most of the
OECD nations over the next two decades. Whereas liquids consumption in
the non-OECD countries is expected to increase by 2.2 percent per year
on average from 2005 to 2030, OECD liquids use increases by 0.3 percent
per year. Sustained high world oil prices are expected to have a more pronounced
impact on the use of liquids in the OECD countries, where many consumers
are not shielded from high market prices by subsidies like those in place
in many of the larger non-OECD consumer nations, including China, India,
and many of the OPEC member countries. As a result, OECD countries respond
more rapidly to high oil prices in the IEO2008 reference case projection,
switching away from liquids wherever possible and reducing demand in the
transportation sector by adopting more efficient motor vehicles and reducing
vehicle-miles traveled.
World Oil Prices
A major factor in the IEO2008 projections is the assumption for future
world oil prices. The impacts of world oil prices on energy demand are
a considerable source of uncertainty in the mid-term projections. Following
the large increases in world oil prices over the past several years, expectations
for future prices also have been raised. In 2006 U.S. dollars, oil prices
in the IEO2008 reference case are about 94 percent higher in 2025 than projections
made only 5 years ago in EIAs International Energy Outlook 2003. The world
oil price cases in IEO2008 are consistent with those in the Annual Energy Outlook 2008.
In every year since 2003, the average price of West Texas Intermediate
(WTI) crude oil, which is indicative of world oil prices as a whole, has
been higher than the average for the previous year. Prices in 2007 were
nearly double 2003 prices in real terms. Prices rose further into the third
quarter of 2008. A variety of factors have caused the increases, including
strong demand growth in non-OECD Asia and the Middle East, no growth in
production from the members of the Organization of the Petroleum Exporting
Countries6 (OPEC) since 2005, rising costs for oil exploration and development,
across-the-board increases in commodity prices, and a weaker U.S. dollar.
In the IEO2008 reference case, prices ease somewhat in the medium term,
as anticipated new productionboth conventional and unconventional (in
Azerbaijan, Brazil, Canada, Kazakhstan, and the United States, for example)reaches
the marketplace. Ultimately, however, markets are expected to remain relatively
tight. In nominal terms, world oil prices in the IEO2008 reference case
decline from their current highs to around $70 per barrel in 2015, then
rise steadily to $113 per barrel in 2030 ($70 per barrel in inflation-adjusted
2006 dollars).
In addition to the reference case, IEO2008 includes high and low price
cases, which help to quantify the considerable uncertainty associated with
long-term projections of future oil prices (Figure 30). Given the price
levels that prevailed in the first 8 months of 2008, however, the high
price case appears to provide a better reflection of current oil market
conditions than does the IEO2008 reference case. The low and high price
cases define a substantial range of $117 per barrel (in nominal dollars).
In the high price case, world oil prices in 2030 are nearly 65 percent
higher than projected in the reference case, at $186 per barrel in nominal
terms. Because high world oil prices slow the growth of demand in the long
term, world liquids consumption in the high price case totals only 99.3
million barrels per day in 2030, 13 million barrels per day lower than
in the reference case.
In the long term, four factors determine the price of oil: growth in world
liquids demand, high production costs for accessible non-OPEC conventional
liquids resources, OPEC investment and production behavior, and the cost
and availability of unconventional liquids supply. It is essential to distinguish
between factors that affect prices in the short term versus the long term,
particularly given the current price environment.
The reference case assumes that OPEC producers will choose to maintain
their market share of world liquids supply, and that OPEC member countries
will invest in incremental production capacity so that their conventional
oil production represents approximately 40 percent of total global liquids
production throughout the projection. As a result, strong economic growth,
especially in the developing world, supports a consistent upward trend
in world oil prices after 2015.
The composition of supply also differs substantially between the reference
and high price cases (Figure 31). As prices rise in the high price case,
the development of previously uneconomical unconventional supplies is encouraged.
As a result, unconventional resources account for a much larger portion
of total liquids supply than in the reference case in 2030 (nearly 20 percent,
as compared with about 9 percent in the reference case). Conventional supplies
decline over the projection period in the high price case, by 1.5 million
barrels per day, compared with an increase of 21.0 million barrel per day
in the reference case. The high price case assumes that OPEC member countries
will maintain their production at near current levels, and that they will
be willing to sacrifice market share as demand for global liquids continues
to grow. The high price case also assumes that oil resources in non-OPEC
countries will be less accessible and/or more expensive than assumed in
the reference case.
Multiple factors restrict conventional liquids production in the high price
case, so that more expensive unconventional liquids are needed to meet
world demand. In particular, access to non-OPEC resources is expected to
be limited, with resource-rich countries such as Kazakhstan and Mexico
being unable to increase their conventional liquids production or unwilling
to do so for geopolitical reasons. In addition, OPEC is expected to constrain
total liquids production to current levels, reducing the OPEC market share
of conventional liquid supplies to 33 percent in 2030 in the high price
case. Although conventional production in the OECD countries decreases
slightly (by 4 percent over the 2005-2030 period), their total liquids
production (both conventional and unconventional) is expected to increase
relative to the reference case, as higher prices make the extraction of
additional barrels of unconventional petroleum liquids, such as oil sands,
more economical. The higher prices and limited access to conventional resources
also result in more significant increases in production of unconventional
liquids in non-OPEC developing countries than are projected in the reference
case.
In the low price case, OPEC is assumed to increase its conventional oil
production to obtain approximately a 44-percent share of total world liquids
production. The low price case also assumes that conventional oil resources
in non-OPEC countries will be more accessible and/or less costly to bring
to market, because of more rapid technology advances, more attractive fiscal
regimes, or both, than in the reference case. As a result, non-OPEC conventional
oil production is higher in the low price case than in the reference case.
Nominal world oil prices decline to about $46 per barrel in 2016 in the
low price case, before climbing to $69 per barrel in 2030. The low world
oil prices discourage fuel conservation and reduce the incentive for development
of nonpetroleum liquids. In the low price case, conventional supplies in
2030 are 14 million barrels per day higher than in the reference case.
Non-OPEC conventional production totals 58.4 million barrels per day in
2030 in the low price case, compared with 55.1 million barrels per day
in the reference case.
Non-OPEC nations increase international access to domestic resources in
the low price case and improve the financial regimes governing the extraction
of those resources. OPEC is assumed to increase its conventional liquids
production share of total liquids to 48 percent in 2030 from 42 percent
in 2005. Changes in the political and fiscal environments of the OPEC member
countries are expected to result in increased production of relatively
inexpensive conventional resources, thus reducing the economic competitiveness
of unconventional liquids production around the world and of conventional
liquids production in the industrialized OECD nations and reducing unconventional
liquids production to approximately one-half the level projected in the
reference case.
World Liquids Production
In the IEO2008 reference case, world liquids production increases by 28
million barrels per day from 2005 to 2030 to meet projected growth in demand.
Increases in production are expected for both OPEC and non-OPEC producers.
About 47 percent of the total world increase in liquids supplies is expected
to come from OPEC member countries. Thus, in 2030, OPEC production is projected
to total 49 million barrels per day and non-OPEC production 63 million
barrels per day.
The reference case assumes that OPEC producers will choose to maintain
their market share of world liquids supply, and that OPEC member countries
will invest in incremental production capacity so that their conventional
oil production represents approximately 40 percent of total global liquids
production throughout the projection. Increasing volumes of conventional
liquids (crude oil and lease condensate, natural gas plant liquids, and
refinery gain) from OPEC members contribute 12.4 million barrels per day
to the total increase in world liquids production, and conventional liquids
supplies from non-OPEC countries add another 8.6 million barrels per day.
The IEO2008 projections are based on a two-stage analytical approach. Projections
of liquids production before 2015 are based largely on a project-by-project
assessment of production volumes and associated scheduling timelines, with
consideration given to the decline rates of active projects, planned exploration
and development activity, and country-specific geopolitical situations
and fiscal regimes. There are often lengthy delays between the point at
which supply projects are announced and when they begin producing. The
extensive and detailed information available about such projects, including
project scheduling and the investment and development plans of companies
and countries, makes it possible to take a detailed approach to modeling
supply.
Because projects generally are not publicized more than 7 to 10 years before
their first production, project-by-project analyses are unlikely to provide
an accurate representation of company or country production plans and achievable
production volumes after 2015. Instead, production decisions made after
2015 are assumed to be based predominantly on resource availability and
the resulting economic viability of production. Geopolitical and other
above-ground constraints7 are not assumed to disappear entirely after
2015, however. Longstanding above-ground factors for which there are no
indications of significant future changesfor instance, the government-imposed
investment conditions currently in place in Iran, or OPEC adherence to
production quotasare expected to continue to affect world supplies long
after 2015.
For some resource-rich countries it is assumed that current political barriers
to increasing production will not continue after 2015. For instance, both
Mexico and Venezuela currently have legislation that restricts foreign
ownership of hydrocarbon resources. Their nationalization of resources
has discouraged investment both foreign and domesticand hindered their
ability to increase or even maintain historical production levels. In the
reference case, both Mexico and Venezuela are assumed to ease restrictions
at some point after 2015, allowing some additional foreign investment or
involvement in their oil sectors that will facilitate increases in liquids
production, including from deepwater prospects in Mexico and heavy oils
in Venezuelas Orinoco belt.
Iraq is another resource-rich country where currently there are significant
impediments to investment in the upstream hydrocarbon sector. Liquids production
in Iraq dropped substantially after the U.S.-led invasion in 2003. From
2003 to 2004 production declined from 2.0 million barrels per day to 1.3
million barrels per day, and it has been relatively slow to recover since
then, not yet reaching the peak production level of 2.6 million barrels
per day that was achieved in 2000. Although Iraqs production levels are
not expected to increase substantially in the near term, it is assumed
that the conflict will end eventually and that renewed investment and development
activity will ensue, resulting in fairly significant growth in production
from 2015 through 2030.
Non-OPEC Production
The world oil prices projected in the IEO2008 reference case are expected
to encourage producers in non-OPEC nations to continue investment in conventional
liquids production capacity and increase investment in enhanced oil recovery
(EOR) projects and unconventional liquids production. Non-OPEC production
increases steadily in the projection, from 48 million barrels per day in
2005 to 63 million barrels per day in 2030, as high prices attract investment
in areas previously considered uneconomical.
Non-OPEC conventional liquids production in the reference case increases
from 47 million barrels per day in 2005 to 50 million barrels per day in
2015 and 55 million barrels per day in 2030. Unconventional liquids production
from non-OPEC suppliers rises to 5 million barrels per day in 2015 and
8 million barrels per day in 2030. In the high price case, non-OPEC unconventional
liquids production rises to 16 million barrels per day in 2030, as high
prices encourage the development of these alternative fuel sources. In
contrast, in the low price case, fewer unconventional resources become
economically competitive, and non-OPEC production of unconventional liquids
rises to only 4 million barrels per day in 2030.
Among non-OPEC producers, the lack of prospects for new, large conventional
petroleum liquids projects and declines in production from existing conventional
fields result in heavy investment in the development of smaller fields.
Producers are expected to concentrate their efforts on more efficient exploitation
of fields already in production, either through the use of more advanced
technology for primary recovery efforts or through EOR. Those efforts are
expected to allow non-OPEC producers to maintain or slow production declines
but not to raise production volumes.
Large increases in non-OPEC production of conventional petroleum liquids
are expected to come from regions with recent large discoveries that have
high undiscovered resource potential but are not yet producing. Significant
gains in conventional production are projected for the Caspian area (Kazakhstan)
and South America (Brazil) (Figure 32). Canada also is expected to be a
major non-OPEC supplier of liquids, with bitumen (oil sands) production
more than compensating for projected declines in its conventional oil production.
The most significant decline in non-OPEC liquids production is projected
for the North Sea, which includes offshore production from Norway, the
United Kingdom, the Netherlands, and Germany. The production projections
for the North Sea are lower in IEO2008 than they were in IEO2007, because
the anticipated rates of production decline are steeper than expected previously
and because of delays in the startup of offshore fields by Norway and by
the United Kingdom (which accounted for a combined 98 percent of total
North Sea production in 2006). Although the long-term projections of production
levels have been reduced, there are positive indications of future prospects
for both Norway (with the opening of the Barents Sea for exploration) and
the United Kingdom (with the development of Buzzard field).
Liquids production from non-OECD Europe and Eurasian producers rises from
11.9 million barrels per day in 2005 to 18.9 million barrels per day in
2030. More than one-half of the increase is attributed to production increases
in Russia, which is the country with the largest projected increase (by
volume) in non-OPEC liquids production in the IEO2008 reference case, at
4.0 million barrels per day from 2005 to 2030.
The Caspian Basin region accounts for a sizable portion of the liquids
production projected for non-OECD Europe and Eurasia in IEO2008. Overall,
production from the Caspian Basin is projected to grow at an average rate
of 3.6 percent per year, resulting in an increment of 3.0 million barrels
per day over the 2005-2030 period. Kazakhstan alone accounts for 2.3 million
barrels per day of the projected increase, primarily as a result of the development
of its Kashagan field and the expansion of gas reinjection at Tengiz, but
also because undiscovered fields in its Caspian territory are expected
to be developed before 2030. The growth of Kazakhstans production will
depend not only on resource availability and extractability, however, but
also, because of its geographical position, on the opening of export routes
a task that will require regional cooperation.
Azerbaijan and Turkmenistan are other Caspian producers expected to increase
their production in the reference case. Turkmenistans production is projected
to grow by more than 6 percent per year in the mid-term and somewhat more
slowly in the long term, in light of the governments evolving attitude
toward foreign investment. Azerbaijans production is projected to grow
rapidly, to a peak production of 1.3 million barrels per day in the next
decade, followed by a decline to 1.0 million barrels per day in 2030.
In Central and South America, Brazils liquids production is projected
to grow at an average annual rate of 4.4 percent from 2005 to 2030, resulting
in an increase of 3.8 million barrels per day over the period. Capacity
expansions at Brazils currently producing fields result in production
increases through 2015, and recent discoveries in the Campos and Santos
Basinswhich suggest the presence of other large fields in the same formationare
projected to lead to additional production increases in the longer term.
North Americas conventional liquids production is projected to fall by
an average of 0.5 percent per year from 2005 to 2030, mainly as a consequence
of the expected exhaustion of attractive conventional prospects in Canada
and a lack of available capital for the development of conventional resources
in Mexico, especially in the deepwater Gulf of Mexico. Increasingly, North
Americas future liquids production is expected to rely on unconventional
productionespecially, from Canadas bitumen resources. In total, North
Americas liquids production is projected to increase by 2.9 million barrels
per day over the period, at an average annual rate of 0.7 percent.
In the United States, total liquids production increases from 8.2 million
barrels per day in 2005 to 10.3 million barrels per day in 2022, then falls
to 9.8 million barrels per day in 2030. The near-term profile of U.S. liquids
production is determined largely by lower 48 offshore production. Deepwater
production in the Gulf of Mexico increases from just under 1.0 million
barrels per day in 2005 to a peak of 2.0 million barrels per day between
2013 and 2019 before beginning to decline. U.S. biofuels production is
projected to rise from 0.2 million barrels per day in 2005 to 1.2 million
barrels per day in 2030 (on an oil equivalent basis), with the United States
accounting for nearly one-half of the total increment in world biofuels
production in the IEO2008 reference case.
In Africa, almost 70 percent of non-OPEC conventional liquids production
currently comes from four countries: Egypt (28 percent), Equatorial Guinea
(16 percent), Sudan (15 percent), and Congo-Brazzaville (10 percent). In
combination, the four are expected to retain approximately a 70-percent
share of Africas non-OPEC conventional production through 2030. Although
the resources of Egypt, the current top producer of conventional petroleum
liquids, are well developed and primary recovery from many of its fields
already is in decline, secondary recovery and EOR efforts are expected
to stabilize Egypts production from previously developed reservoirs in
the mid-term. In 2030, Sudan is expected to be the largest non-OPEC producer
in Africa, at 0.9 million barrels per day, with most of the growth occurring
after 2020.
Conventional liquids production in Congo-Brazzaville more than doubles
in the IEO2008 reference case, from 0.2 million barrels per day in 2005
to 0.6 million barrels per day in 2030, which would make it the regions
third largest non-OPEC producer. Recent field discoveries, including Moho
Nord Marine 1 and Pegase Nord Marine 1, have served both to increase international
interest in the region and to promote the possibility of additional large
finds in the future. Given that most of the recent discoveries have been
in deepwater locations where there has been little previous exploration,
growth in the countrys production is expected to come from known and potential
deepwater resources.
Non-OPEC producers in Asia are projected to increase their total liquids
production from 7.2 million barrels per day in 2005 to 8.6 million barrels
per day in 2030. China is Asias largest non-OPEC producer of total liquids
by far, at 3.7 million barrels per day in 2005, followed by India at 0.8
million barrels per day, and Malaysia at 0.7 million barrels per day. Chinas
production is expected to be maintained at about 4.0 million barrels per
day through 2030, and Indias production is projected to increase to slightly
more than 1.2 million barrels per day in 2030.
Liquids production from Australia/New Zealand is projected to increase
from 0.6 million barrels per day in 2005 to 0.7 million barrels per day
in 2030. Near-term increases in crude oil and condensate production are
expected for both Australia and New Zealand, mainly as a result of recent
discoveries and developments in offshore basins (such as the Carnarvon
Basin). A decline to lower, relatively stable production levels is projected
over the longer term. For both countries, production of natural gas plant
liquids (NGPL) is projected to remain around current levels in the near
term, followed by significant growth as recently discovered large fields
are developed and the natural gas is extracted and processed. With the
expected surge in NGPL production, total conventional liquids production
is projected to increase slightly from 2005 to 2030.
In addition to increasing their production of conventional liquids, both
China and India are expected to increase biofuels and CTL production. Unconventional
liquids production in China rises to 0.4 million barrels per day in 2030,
with CTL accounting for 65 percent and biofuels the remainder. In India,
unconventional production rises to 0.2 million barrels per day in 2030,
with 44 percent attributed to CTL and 56 percent to biofuels. Advances
in technologiesfor instance, direct coal liquefaction that would improve
the efficiency of CTL production and make it more economicalare not expected
to become commercially viable until late in the projection period.
OPEC Production
OPECs total liquids production increases at a 1.3-percent average annual
rate from 2005 to 2030 in the IEO2008 reference case, resulting in the
production of 49.3 million barrels of liquids per day in 2030, of which
31.8 million barrels per day originates in the Middle East (Figure 33).
By volume, the largest increase in the individual OPEC countries liquids
production is projected for Saudi Arabia: from 11.1 million barrels per
day in 2005 to 13.7 million barrels per day in 2030.
The most rapid growth in OPEC production is projected for Qatar, where
total liquids production rises at an average annual rate of 4.3 percent
over the projection period, including an increase in GTL production to
0.2 million barrels per day in 2030. In addition, Qatars NGPL production
increases at an average annual rate of 6.1 percent, and its crude oil and
condensate production increases by an average of 3.1 percent per year.
The second-fastest growth rate in liquids production among the OPEC countries
is projected for Angola, averaging 3.7 percent per year from 2005 to 2030.
Almost all the increase is expected to consist of crude oil and lease condensate
production from offshore projects. Established OPEC production targets
(in December 2007, Angola received a target of 1.9 million barrels per
day) are not expected to impede project development in Angola, and its
production in 2030 is projected to be 3.1 million barrels per day in the
reference case.
Iraqs liquids production also grows substantially, by an average of 3.1
percent per year, depending on developments in the countrys political
situation. The IEO2008 projections assume that the conflict in Iraq will
be resolved well before 2030, making resource availability the main determining
factor in its ability to meet growing domestic demand. From 2005 to 2015,
Iraqs liquid fuels production is projected to grow by only 1.4 percent
per year, but from 2015 to 2030 the average annual growth rate increases
to 4.3 percent.
Total liquids production in Iran also is expected to be restricted by geopolitical
factors through 2015. Those factors are not limited to international relations
but also include a variety of other non-resource-related factors that range
from the effectiveness of the national oil companys operations to the
ability of the government and foreign investors to agree on contractual
terms. In the IEO2008 reference case, Irans oil production remains relatively
stable through 2015, both because of financial and political constraints
on developing new oil or natural gas prospects and because of anticipated
competing demands for natural gas that would limit its use (and thus effectiveness)
for improving oil recovery through natural gas reinjection. The reference
case does not project large increases in Irans liquids production, because
it does not assume improvements in either the political or investment environment
for the country.
For Venezuela, liquids production is constrained by investor concerns over
government actions that nationalized the upstream hydrocarbon sector, as
well as the possibility of further mandated changes in contract terms.
Venezuelas total liquids production falls somewhat in the reference case,
from 2.9 million barrels per day in 2005 to 2.5 million barrels per day
in 2010, before beginning a steady recovery to 3.5 million barrels per
day in 2030. This is a much more pessimistic outlook for Venezuelas production
profile than in past IEOs. In IEO1999, which was published only a month
after Hugo Chavez assumed the Venezuelan Presidency, the countrys annual
liquids production was projected to reach 5.5 million barrels per day in
20202.4 million barrels per day more than projected in the IEO2008 reference
case.
Unconventional Production
Unconventional liquids play an increasingly important role in meeting demand
for liquid fuels over the course of the IEO2008 projection. In the reference
case, 8.6 percent of world liquids supply in 2030 is projected to come
from unconventional sources, including 1.6 million barrels per day originating
from OPEC and 8.1 million from non-OPEC countries. Although unconventional
production volumes vary between the IEO2008 price cases (from 19.0 percent
in the high price case to 4.0 percent in the low price case), the geographic
locations and types of unconventional production remain relatively unchanged.
OPECs unconventional production consists predominantly of extra-heavy
Orinoco oil production in Venezuela and GTL production in Qatar, with 2030
production volumes ranging from 1.1 to 2.1 million barrels per day and
0.2 to 0.5 million barrels per day, respectively, in the high and low price
cases. Although the resources to support production at those levels abound
in the two countries, large investments will be required to produce them,
and the timing of such investments is uncertain.
Outside the OPEC member countries, unconventional liquids production comes
from a much more diverse group of countries and resource types. As a whole,
non-OPEC unconventional liquids production is projected to increase by
more than 6.4 million barrels per day from 2005 to 2030, with 72.4 percent
coming from OECD countries. By volume, the largest contributors to the
non-OPEC increase are expected to be bitumen (Canadian oil sands) and biofuels,
with production increases of 3.1 and 2.2 million barrels oil equivalent
per day, respectively, from 2005 to 2030.
Although bitumen and biofuels are viewed as having the most potential for
significant contributions to global liquids supply, they also show the
most significant variations in production levels among the price cases
as a result of the effects of different price assumptions on production
economics and competing supply from conventional liquids. The projected
increases from 2005 to 2030 in Canadas bitumen production range from less
than 0.3 million barrels per day in the low price case to 7.6 million barrels
per day in the high price case, and the increases in biofuels production
ranging from 1.2 million barrels per day in the low price case to 3.7 million
barrels per day in the high price case. In the reference case, the most
significant increases in biofuels production from 2005 to 2030 are projected
for the United States (1.0 million barrels per day) and Brazil (0.5 million
barrels per day). Increases of approximately 60 thousand barrels per day
are projected for South Africa, China, India, and Argentina.
Like biofuels production, CTL production volumes vary among the price cases,
although they do not add as much to total liquids production. In the low
price case, South Africa is the largest CTL supplier, producing 112,000
barrels per day in 2030, with China, India, and the United States contributing
smaller volumes. In the reference case, the United States and China increase
their CTL production by 242,000 and 246,000 barrels per day, respectively,
from 2005 to 2030; South Africa increases its production by only 209,000
barrels per day but still remains the dominant CTL supplier, at 340,000
barrels per day in 2030. In the high price case, improved production economics
result in the expansion of CTL projects around the world and the production
of 2.7 million barrels per day in 20302.5 million barrels per day more
than was produced in 2005.
In all three cases, non-OPEC production of extra-heavy oil, GTL, and shale
oil contributes a relatively small fraction of liquids to the world market.
Mexico is expected to be the only non-OPEC supplier of extra-heavy oil,
with volumes ranging from 19,000 to 120,000 barrels per day in 2030 in
the low and high price cases, respectively. In the reference and low price
cases, South Africa is the worlds only non-OPEC supplier of GTL; however,
in the high price case the United States and South Africa produce approximately
the same volumes, at just over 120,000 barrels per day in 2030. Similarly,
shale oil production is expected to originate from only one country in
the reference and low price cases (Estonia), but in the high price case
the United States produces 144,000 barrels of shale oil per day in 2030.
Oil Reserves and Resources
As of January 1, 2008, proved world oil reserves, as reported by the Oil
& Gas Journal, were estimated at 1,332 billion barrels14 billion barrels
(about 1 percent) higher than the estimate for 2007 [4]. According to the Oil & Gas Journal, 56 percent of the worlds proved oil reserves are located
in the Middle East (Figure 34). Among the top 20 reserve holders in 2008,
11 are OPEC member countries that, together, account for 69 percent of
the worlds total reserves (Table 4).
Proved reserves of crude oil are the estimated quantities that geological
and engineering data demonstrate with reasonable certainty can be recovered
in future years from known reservoirs, assuming existing technology and
current economic and operating conditions. Companies whose stocks are publicly
traded on U.S. stock markets are required by the U.S. Securities and Exchange
Commission (SEC) to report their holdings of domestic and international
proved reserves, following specific guidelines. Country-level estimates
of proved reserves are developed from the data reported to the SEC, from
foreign government reports, and from international geologic assessments.
Estimates are not always updated annually.
Whereas proved reserves include only those estimated quantities of crude
oil from known reservoirs, they are only a subset of the entire potential
oil resource base. Resource base estimates include estimated quantities
of both discovered and undiscovered liquids that have the potential to
be classified as reserves at some time in the future. The resource base
may include oil that currently is not technically recoverable but could
conceivably become recoverable in the future as technologies advance.
Readers may notice that, in some cases in the IEO2008 projections, country-level
volumes for cumulative production through 2030 exceed the estimates of
proved reserves. This does not imply that resources and the physical limits
of production have not been considered in the development of production
forecasts, or that the projections assume a rapid decline in production
immediately after the end of the projection period as reserves are depleted.
EIA carefully considers resource availability in all long-term country-level
projections, the aggregation of which gives the total world production
projection; however, proved reserves are not an appropriate measure for
judging total resource availability in the long run.
In order to construct realistic and plausible projections for liquids production,
and especially for petroleum liquids production, underlying analysis must
both consider production beyond the intended end of the projection period
and base production projections on the physical realities and limitations
of production. The importance of approaching an assessment of liquids production
in this way is illustrated by the recent history of U.S. reserve estimates.
Whereas the United States reported 22.1 billion barrels of proved reserves
in 1998, proved reserves of 21.0 billion barrels were reported in 2008a
decrease of only 1.1 billion barrels despite the cumulative 32.1 billion
barrels of liquids supplied from U.S. reserves between 1998 and 2007.
Proved reserves cannot provide an accurate assessment of the physical limits
on future production but rather are intended to provide insight as to company-
or country-level development plans in the very near term. In fact,
because of the particularly rigid requirements for the classification of
resources as proved reserves, particularly by the U.S. SEC,8 even the cumulative
production levels from individual development projects may exceed the initial
estimates of proved reserves.
EIA attempts to address the lack of applicability of proved reserves estimates
to long-term production projections by developing a production methodology
based on the true physical limits of production (see "Defining the Limits of Oil Production"). By
basing the long-term EIA production assessments on resources, rather than
reserves, EIA is able to present projections that are physically achievable
and can be supported beyond the 2030 projection horizon in IEO2008. The
realization of such production levels depends, however, on future growth
in world demand, taking into consideration such above-ground limitations
on production as profitability and specific national regulations, among
others.
