31 Facts About Crude oil

Once extracted, Crude oil is refined and separated, most easily by distillation, into numerous products for direct use or use in manufacturing.

Petroleum production can be extremely profitable and was important for economic development in the 20th century, with some countries, so called "Crude oil states", gaining significant economic and international power because of their control of Crude oil production.

Additionally, Crude oil has been a source of conflict leading to both state-led-wars and other kinds of conflicts .

Crude oil was often distilled by Persian chemists, with clear descriptions given in Arabic handbooks such as those of Muhammad ibn Zakariya Razi .

Crude oil's achievements included the discovery of how to distill kerosene from seep oil, the invention of the modern kerosene lamp, the introduction of the first modern street lamp in Europe, and the construction of the world's first modern oil well .

At around the same time the world's first, small, Crude oil refinery was opened at Jaslo in Poland, with a larger one opened at Ploiesti in Romania shortly after.

Access to Crude oil was and still is a major factor in several military conflicts of the twentieth century, including World War II, during which Crude oil facilities were a major strategic asset and were extensively bombed.

Top three Crude oil producing countries are Russia, Saudi Arabia and the United States.

An oil well produces predominantly crude oil, with some natural gas dissolved in it.

Hydrocarbons in crude oil are mostly alkanes, cycloalkanes and various aromatic hydrocarbons, while the other organic compounds contain nitrogen, oxygen and sulfur, and trace amounts of metals such as iron, nickel, copper and vanadium.

In Canada, bitumen is considered a sticky, black, tar-like form of crude oil which is so thick and heavy that it must be heated or diluted before it will flow.

The lighter grades of crude oil produce the best yields of these products, but as the world's reserves of light and medium oil are depleted, oil refineries are increasingly having to process heavy oil and bitumen, and use more complex and expensive methods to produce the products required.

Above the maximum temperature the Crude oil is converted to natural gas through the process of thermal cracking.

Abiogenic sources of Crude oil have been found, but never in commercially profitable amounts.

Technically speaking, Crude oil shales are not always shales and do not contain Crude oil, but are fined-grain sedimentary rocks containing an insoluble organic solid called kerogen.

The kerogen in the rock can be converted into crude oil using heat and pressure to simulate natural processes.

Light crude oil is more desirable than heavy oil since it produces a higher yield of gasoline, while sweet oil commands a higher price than sour oil because it has fewer environmental problems and requires less refining to meet sulfur standards imposed on fuels in consuming countries.

Barrels from an area in which the crude oil's molecular characteristics have been determined and the oil has been classified are used as pricing references throughout the world.

Once extracted, Crude oil is refined and separated, most easily by distillation, into numerous products for direct use or use in manufacturing, such as gasoline, diesel and kerosene to asphalt and chemical reagents used to make plastics, pesticides and pharmaceuticals.

Global price of crude oil was relatively consistent in the nineteenth century and early twentieth century.

Crude oil and refined fuel spills from tanker ship accidents have damaged natural ecosystems and human livelihoods in Alaska, the Gulf of Mexico, the Galapagos Islands, France and many other places.

Control of Crude oil spills is difficult, requires ad hoc methods, and often a large amount of manpower.

Tarball is a blob of crude oil which has been weathered after floating in the ocean.

The researchers noted Crude oil exploitation gave politicians "an incentive to extend civil liberties but reduce political rights in the presence of Crude oil windfalls to evade redistribution and conflict".

Peak Crude oil is a term applied to the projection that future petroleum production will eventually peak and then decline at a similar rate to the rate of increase before the peak as these reserves are exhausted.

Just as the 1971 U S peak in oil production was only clearly recognized after the fact, a peak in world production will be difficult to discern until production clearly drops off.

In 2020, according to BP's Energy Outlook 2020, peak Crude oil had been reached, due to the changing energy landscape coupled with the economic toll of the COVID-19 pandemic.

Former Crude oil exporters are expected to lose power, while the positions of former Crude oil importers and countries rich in renewable energy resources is expected to strengthen.

Unconventional Crude oil is petroleum produced or extracted using techniques other than the conventional methods.

The calculus for peak Crude oil has changed with the introduction of unconventional production methods.

The large increase in tight Crude oil production is one of the reasons behind the price drop in late 2014.
