Petroleum, also known as crude oil and oil, is a naturally occurring, yellowish-black liquid found in geological formations beneath the Earth's surface. It is commonly refined into various types of fuels. Components of petroleum are separated using a technique called fractional distillation, i.e. separation of a liquid mixture into fractions differing in boiling point by means of distillation, typically using a fractionating column. It consists of naturally occurring hydrocarbons of various molecular weights and may contain miscellaneous organic compounds. The name petroleum covers both naturally occurring unprocessed crude oil and petroleum products that are made up of refined crude oil. A fossil fuel, petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock and subjected to both intense heat and pressure.
An energy crisis is any significant bottleneck in the supply of energy resources to an economy. In literature, it often refers to one of the energy sources used at a certain time and place, in particular, those that supply national electricity grids or those used as fuel in industrial development and population growth have led to a surge in the global demand for energy in recent years. In the 2000s p, this new demand — together with Middle East tension, the falling value of the US dollar, dwindling oil reserves, concerns over peak oil, and oil price speculation — triggered the 2000s energy crisis, which saw the price of oil reach an all-time high of $147.30 a barrel in 2008
The Hubbert peak theory says that for any given geographical area, from an individual oil-producing region to the planet as a whole, the rate of petroleum production tends to follow a bell-shaped curve. It is one of the primary theories on peak oil.
Peak oil is the year when the maximum rate of extraction of petroleum is reached, after which it is expected to enter terminal decline. As of 2021, peak oil forecasts range from 2019 to 2040, depending on economics and how governments respond to global warming. It is often confused with oil depletion; however, whereas depletion refers to a period of falling reserves and supply, peak oil refers to the point of maximum production. The concept of peak oil is often credited to geologist M. King Hubbert whose 1956 paper first presented a formal theory. Peak coal was in 2013 and peak oil is forecast to occur before peak gas.
Petroleum politics have been an increasingly important aspect of diplomacy since the rise of the petroleum industry in the Middle East in the early 20th century. As competition continues for a vital resource, the strategic calculations of major and minor countries alike place prominent emphasis on the pumping, refining, transport, sale and use of petroleum products.
Colin J. Campbell is a retired British petroleum geologist who predicted that oil production would peak by 2007. He claims the consequences of this are uncertain but drastic, due to the world's dependency on fossil fuels for the vast majority of its energy. His theories have received wide attention but are disputed and have not significantly changed governmental energy policies at this time. To deal with declining global oil production, he has proposed the Rimini protocol.
From the mid-1980s to September 2003, the inflation-adjusted price of a barrel of crude oil on NYMEX was generally under US$25/barrel in 2008 dollars. During 2003, the price rose above $30, reached $60 by 11 August 2005, and peaked at $147.30 in July 2008. Commentators attributed these price increases to many factors, including Middle East tension, soaring demand from China, the falling value of the U.S. dollar, reports showing a decline in petroleum reserves, worries over peak oil, and financial speculation.
Oil reserves denote the amount of crude oil that can be technically recovered at a cost that is financially feasible at the present price of oil. Hence reserves will change with the price, unlike oil resources, which include all oil that can be technically recovered at any price. Reserves may be for a well, a reservoir, a field, a nation, or the world. Different classifications of reserves are related to their degree of certainty.
The price of oil, or the oil price, generally refers to the spot price of a barrel of benchmark crude oil—a reference price for buyers and sellers of crude oil such as West Texas Intermediate (WTI), Brent Crude, Dubai Crude, OPEC Reference Basket, Tapis crude, Bonny Light, Urals oil, Isthmus and Western Canadian Select (WCS). There is a differential in the price of a barrel of oil based on its grade—determined by factors such as its specific gravity or API gravity and its sulfur content—and its location—for example, its proximity to tidewater and refineries. Heavier, sour crude oils lacking in tidewater access—such as Western Canadian Select—are less expensive than lighter, sweeter oil—such as WTI.
Big Oil is a name used to describe the world's six or seven largest publicly traded oil and gas companies, also known as supermajors. The term emphasizes their economic power and influence on politics, particularly in the United States. Big Oil is often associated with the fossil fuels lobby and also used to refer to the industry as a whole in a pejorative or derogatory manner.
Energy security is the association between national security and the availability of natural resources for energy consumption. Access to (relatively) cheap energy has become essential to the functioning of modern economies. However, the uneven distribution of energy supplies among countries has led to significant vulnerabilities. International energy relations have contributed to the globalization of the world leading to energy security and energy vulnerability at the same time.
The Oil Depletion Analysis Centre (ODAC) is an independent, UK-registered educational charity. The centre is working to raise international public awareness and promote better understanding of the world's oil depletion and peak oil problem. It is based in London and belongs to the New Economics Foundation.
The mitigation of peak oil is the attempt to delay the date and minimize the social and economic effects of peak oil by reducing the consumption of and reliance on petroleum. By reducing petroleum consumption, mitigation efforts seek to favorably change the shape of the Hubbert curve, which is the graph of real oil production over time predicted by Hubbert peak theory. The peak of this curve is known as peak oil, and by changing the shape of the curve, the timing of the peak in oil production is affected. An analysis by the author of the Hirsch report showed that while the shape of the oil production curve can be affected by mitigation efforts, mitigation efforts are also affected by the shape of Hubbert curve.
Oil megaprojects are large oil field projects.
Peak oil is the point at which oil production, sometimes including unconventional oil sources, hits its maximum. Predicting the timing of peak oil involves estimation of future production from existing oil fields as well as future discoveries. The most influential production model is Hubbert peak theory, first proposed in the 1950s. The effect of peak oil on the world economy remains controversial.
The 1980s oil glut was a serious surplus of crude oil caused by falling demand following the 1970s energy crisis. The world price of oil had peaked in 1980 at over US$35 per barrel ; it fell in 1986 from $27 to below $10. The glut began in the early 1980s as a result of slowed economic activity in industrial countries due to the crises of the 1970s, especially in 1973 and 1979, and the energy conservation spurred by high fuel prices. The inflation-adjusted real 2004 dollar value of oil fell from an average of $78.2 in 1981 to an average of $26.8 per barrel in 1986.
Petroleum in the United States has been a major industry since shortly after the oil discovery in the Oil Creek area of Titusville, Pennsylvania in 1859. The industry includes exploration, production, processing (refining), transportation, and marketing of natural gas and petroleum products. As of 2019, the United States is the world's largest oil producer. The leading oil-producing area in the United States in 2019 was Texas, followed by the offshore federal zone of the Gulf of Mexico, North Dakota and New Mexico.
The proven oil reserves in Saudi Arabia are the reportedly 2nd largest in the World , estimated to be 268 billion barrels, including 2.5 Gbbl in the Saudi–Kuwaiti neutral zone. They are predominantly found in the Eastern Province. These reserves were apparently the largest in the world until Venezuela announced they had increased their proven reserves to 297 Gbbl in January 2011. The Saudi reserves are about one-fifth of the world's total conventional oil reserves. A large fraction of these reserves comes from a small number of very large oil fields, and past production amounts to 40% of the stated reserves.
The 1970s energy crisis occurred when the Western world, particularly the United States, Canada, Western Europe, Australia, and New Zealand, faced substantial petroleum shortages, real and perceived, as well as elevated prices. The two worst crises of this period were the 1973 oil crisis and the 1979 energy crisis, when the Yom Kippur War and the Iranian Revolution triggered interruptions in Middle Eastern oil exports.
