In Fifteen years during the last half of the 20th century major disruptions in world oil supplies have occurred. Six of those instances
decreased the world oil supply by at least 2 million barrels per day162.
Suez War - 1956
Six Day War - 1967
Arab Oil Embargo - 1973
Iran Revolution - 1979
Iran/Iraq War - 1981
Iraq Invades Kuwait - 1991
The 1973 Arab Oil Embargo163 was the first oil supply disruption to cause major price increases and an energy crisis164.
U.S. refiners made short-term changes in oil purchasing and began importing crude oil from any available source. About 30% less of
the more costly crude oil was imported during the embargo. Iran at the time appeared to be a stable, long-term source. Iran moved to
expand sales to the United States, and these imports served to offset losses from Kuwait and Libya until Libyan crude oil imports resumed
in early 1975.
Imports from other Arab OPEC countries resumed shortly after the embargo ended in March 1974, and continued to climb through
1977. Despite production buildups from the North Sea and Alaska, Arab OPEC's share of U.S. crude oil imports increased from nearly 26 percent in 1973 to 36% in 1977, when imports were than at historic high levels which were not again reached until 1994.
The refining industry moved to develop technology and processing methods to reduce fuel consumption and to increase
operating efficiency.
The embargo caused sudden price hikes and short-term shortages of refined products after decades of ample supplies and
growing consumption. Tight supplies caused lines to form at gasoline stations. All petroleum products were much more costly. From
1972 to 1975, when OPEC restored output to pre-embargo levels, consumers were paying approximately 57 percent more for leaded
regular gasoline and 91 percent more for home heating oil. These increases reflect the increase in world oil prices over the period.
The large jump in energy prices is widely considered to be a cause of the economic recession that occurred in 1974 and 1975, though
some later economic studies indicate that other factors may have contributed.
Various efforts were undertaken to conserve energy and to switch from petroleum to less expensive alternative fuels.
Petroleum consumption declined both in 1974 and 1975 as a result of conservation efforts. Alternative fuels in some industrial and electric
utility facilities replaced large volumes of distillate fuel oil and residual fuel oil.
To plan for future supply disruptions and to establish secure stable supplies, the United States joined with 20 other nations in
1974 to form the International Energy Agency (IEA). Member nations, including the United States, developed plans to establish
strategic reserves for use in any future supply disruptions.
Legislation was put in place over the next several years that had a significant impact on all aspects of the petroleum industry.
In 1950, the United States provided 52 percent of the world's crude oil production; by 1997 that figure had dropped to 10 percent. Virtually
all spare oil production capacity was in the Middle East when the Arab Oil Embargo began in October 1973. Supply disruptions increased in
severity as world oil production increased and production shifted to less secure areas of the Middle East165.
In 1986 OPEC members led by Saudi Arabia introduced netback pricing which led to an Oil Glut166. Prices collapsed to $9.85 per barrel.
The collapse of crude oil prices in 1986 reversed the upward trend in U.S. production of the first half of the decade. Many high-cost
wells, which became productive after the oil crisis of 1978-1980, became unprofitable in 1986 and were shut in. Domestic crude oil
production began dropping in early 1986. After the world price fell more than 50 percent between January and March 1986, drilling
plummeted. Since then, domestic drilling and production have gradually declined.
The net effect of the decline in domestic production beginning in 1986 was an increase in crude oil imports, which climbed from
3.2 million barrels per day in 1985 to 9.1 million barrels per day in 2000. Most of this increase was met by OPEC, whose share of total
U.S. crude oil imports rose from 41 percent in 1985 to 60 percent in 1990, before dropping to 46 percent in 1995-1997. Since 1998, the
share has gradually increased, reaching 51 percent in 2000.
Oil company investments began shifting to foreign oil exploration and production after the 1986 price drop. Foreign fields are
generally much larger than in the United States and average production costs are lower. Changes in policy in the former Soviet Union
since 1991 have increased U.S. production investment there, and recent moves toward foreign investments in Mexico have attracted
American exploration and production companies.
The sharp drop in crude oil prices pushed U.S. petroleum demand steadily higher in the second half of the decade. From 1985 to
2000, demand climbed from 15.7 million barrels per day to 19.5 million barrels per day.
Until 1986, the value of U.S. petroleum imports comprised between 15 percent and 32 percent of all imported goods. The steep
decline in petroleum prices in 1986 reduced petroleum's portion of the U.S. trade deficit.
The economy expanded at a faster pace in 1987 and 1988. Low petroleum prices stimulated growth in industrial production,
employment increased, and travel picked up. Temporary conservation measures that had been instituted during earlier oil price
escalations were discontinued. The overall energy intensity of the economy (measured by the ratio of total energy consumption to the
constant dollar level of the Gross Domestic Product), a reflection of energy conservation, did not increase between 1986 and 1988.
The share of total U.S. consumption of imported oil has grown since oil prices collapsed in 1986. Gross imports account for 53 percent of
U.S oil consumption167.
The Iranian Revolution, which began in late 1978, resulted in a drop of 3.9 million barrels per day of crude oil production from Iran from
1978 to 1981. In 1980, the Iran-Iraq War began, and many Persian Gulf countries reduced output as well. By 1981, OPEC production declined
to 22.8 million barrels per day, 7.0 million barrels per day below its level for 1978168.
Over the same period, as U.S. refiners imported proportionately more crude oil from Canada, Mexico, the United Kingdom, and other
non-OPEC countries, OPEC's share of U.S. crude oil imports fell from 82 percent to 41 percent.
The high cost of crude oil stimulated exploration and production operations in non-OPEC countries, prolonged the productive
life of marginal wells, and made secondary and tertiary production techniques profitable. In addition to these trends, development projects
in the North Sea, Mexico, and the North Slope of Alaska began to contribute significantly to world crude oil supplies. By 1985, non-
OPEC production comprised 69 percent of total world production, up from 50 percent in 1978. These trends allowed U.S. refiners to tap
new sources of non-OPEC supply.
The higher oil prices depressed U.S. petroleum consumption and encouraged fuel-switching and energy conservation. Other
fuels replaced petroleum in many applications, and industrial processes, appliances, equipment, and motors were made more efficient.
These developments had a large impact on U.S. petroleum demand, which from 1978 to 1983 fell from 18.8 to 15.2 million barrels per day,
the lowest level since 1971.
Iraq invaded Kuwait on August 2, 1990, causing crude oil and product prices to rise suddenly and sharply for the third time in 17 years
reaching about $36 per barrel169.
Permanent energy efficiency improvements had been made to U.S. automobiles, housing, and industrial machinery since the
Iranian Revolution. The development of multi-fuel boilers had enhanced industrial and electric utility plants' ability to switch from petrol
eum when its price relative to natural gas became too high.
The b need felt during the 1970s to build up stocks in anticipation of market tightness or uncertainty had been reduced. This resulted
from the realization that SPR oil could be available if supply shortages occurred, and from the utilization of the futures market to hedge
against large swings in price.
Participants in the futures market in the 90 days following the invasion were mostly refiners, airlines, and chemical companies who
used oil and wanted to guarantee prices for their customers. There was no apparent increase in speculative activity, and the futures market
did not contribute to the run-up in prices or to price volatility. The rise in crude oil and petroleum product prices occurred because
of uncertainties regarding the spread of the invasion and replacement of supplies. After peaking in mid-October domestic and worldwide
prices dropped substantially by the end of 1990.
European supplies were tight after Kuwait's petroleum product exports to Europe and the Far East ceased. The United States
began exporting motor gasoline to countries in Western Europe that had previously been sources of imports. Exports of distillate fuel
oil and kerosene-type jet fuel to Canada and the Far East escalated, also. Product exports from Kuwait had not returned to pre-crisis levels
