Non-OPEC countries contain less than one-fourth of the world's
proven oil reserves but produce nearly 60 percent of the world's oil.
They also possess most of the world's capacity for refining crude oil
into petroleum products such as gasoline and heating oil. Because
non-OPEC countries have smaller reserves which are being depleted
more rapidly than in OPEC, their overall reserves-to-production ratio
-- an indicator of how long proven reserves would last at current
production rates -- is much lower (about 14 years for non-OPEC and
73 years for OPEC). In the future, non-OPEC production is expected
to increase less rapidly than in OPEC and, as a result, shrink to less
than 50 percent of total world oil production by 2015 (see EIA's
International Energy Outlook 1997).
The oil industries in non-OPEC countries differ from those of OPEC countries in several fundamental ways:
Current non-OPEC production is concentrated in seven countries,
each of which produced between 1.9 million and 6.4 million
barrels/day of crude oil in 1997. Together, these countries account for
about 60 percent of non-OPEC production and for more than 60
percent of non-OPEC proven oil reserves. Of these, the United States
and Russia are the largest producers, and Russia and Mexico have the
largest reserves.
While Russia, Mexico, Norway, the United Kingdom, and Canada are net exporters to the world oil market, the United States and China must import additional oil to meet high oil demand in their domestic markets.
Also shown are Azerbaijan and Kazahkstan, which have extensive reserves but currently low production levels. The ratio of reserves to production in each of these countries is, therefore, significantly higher than in the major oil-producing countries shown here.
The remaining sources of non-OPEC oil are highly diversified and include 13 countries producing 0.3-0.9 million barrels/day. These countries all have proven oil
reserves in the range of 1-6 billion barrels.
Other non-OPEC countries with active oil industries producing at least 100,000 barrels/day each include: Brunei, Cameroon, Congo, Denmark, Italy, Peru,
Romania, Trinidad and Tobago, Turkmenistan, and Vietnam. Together, these countries with combined proven oil reserves of about 9 billion barrels produced a
combined total of about 1.5 million barrels/day in 1997.
