Oil and crude oil are two terms that are often used interchangeably, but they actually refer to two different things. In this article, we will explore the difference between oil and crude oil, including their definitions, uses, and how they are traded.
Definitions
Oil is a broad term that refers to any liquid hydrocarbon that is used as a fuel or lubricant. This can include a variety of different substances, including gasoline, diesel fuel, and motor oil.
Crude oil, on the other hand, is a specific type of oil that is extracted from the ground. Crude oil is a mixture of hydrocarbons that is found in underground reservoirs and is typically black or dark brown in color. Crude oil is the raw material that is refined to produce a variety of different petroleum products, including gasoline, diesel fuel, and jet fuel.
Uses
Oil and crude oil are both used as fuels and lubricants, but they are used in different ways. Oil is typically used as a fuel for transportation, including cars, trucks, and airplanes. It is also used as a lubricant in engines and machinery.
Crude oil, on the other hand, is used as a raw material to produce a variety of different petroleum products. These products include gasoline, diesel fuel, jet fuel, heating oil, and lubricants. Crude oil is also used to produce a variety of non-fuel products, including plastics, synthetic fibers, and fertilizers.
Trading
Oil and crude oil are both traded on a number of different exchanges around the world. However, the way they are traded is different.
Oil is typically traded as a finished product, such as gasoline or diesel fuel. These finished products are traded on commodity exchanges, such as the New York Mercantile Exchange (NYMEX) or the Intercontinental Exchange (ICE). Investors and traders can buy and sell futures contracts for these finished products, allowing them to speculate on the price of oil.
Crude oil, on the other hand, is traded as a raw material. Crude oil futures contracts are traded on commodity exchanges, such as the NYMEX or the ICE. These contracts represent the right to buy or sell a certain amount of crude oil at a specific price and date in the future.
Crude oil futures contracts are typically denominated in US dollars and represent the price of West Texas Intermediate (WTI) crude oil. Each contract represents the delivery of 1,000 barrels of crude oil at a specific date in the future. Investors and traders can buy and sell these contracts, allowing them to speculate on the price of crude oil.
Differences in Quality
Another key difference between oil and crude oil is their quality. Oil is typically refined to produce a specific grade of fuel or lubricant. This means that the quality of oil can vary depending on the intended use.
Crude oil, on the other hand, can vary significantly in quality depending on where it is extracted from. Crude oil can contain a variety of impurities, including sulfur, nitrogen, and heavy metals. The quality of crude oil can also vary depending on its density and viscosity.
To ensure consistency in the quality of crude oil, it is typically classified using a grading system. The most commonly used grading system is the American Petroleum Institute (API) gravity scale. This scale measures the density of crude oil relative to water and is used to classify crude oil into different grades.
Processing
Oil and crude oil also differ in their processing requirements. Oil is typically refined to produce a specific grade of fuel or lubricant. This involves a process known as fractional distillation, which separates the different components of oil based on their boiling points.
During fractional distillation, oil is heated and the vapor is passed through a series of condensers. As the vapor cools, it condenses into different fractions, each of which has a different boiling point. These fractions are then further processed to produce different grades of fuel or lubricant.
Crude oil, on the other hand, must be processed before it can be used as a fuel or lubricant. This involves a process known as refining, which involves a series of physical and chemical processes to separate the different components of crude oil.
During refining, crude oil is heated and the vapor is passed through a series of distillation towers. As the vapor cools, it condenses into different fractions, each of which has a different boiling point. These fractions are then further processed to remove impurities and produce different grades of fuel or lubricant.
Environmental Impact
Oil and crude oil also differ in their environmental impact. Oil is a finished product that is used as a fuel for transportation, which can contribute to air pollution and greenhouse gas emissions. Oil spills can also have a significant impact on the environment, damaging ecosystems and harming wildlife.
Crude oil, on the other hand, has a lower environmental impact than oil. While the extraction and refining of crude oil can have environmental impacts, such as habitat destruction and water pollution, crude oil is not directly used as a fuel. Instead, it is processed to produce different grades of fuel and lubricant, which can be used more efficiently and with lower environmental impact than oil.
Conclusion
In conclusion, the difference between oil and crude oil is significant. Oil is a broad term that refers to any liquid hydrocarbon that is used as a fuel or lubricant, while crude oil is a specific type of oil that is extracted from the ground and is used as a raw material to produce a variety of different petroleum products.
Oil is typically traded as a finished product, while crude oil is traded as a raw material. The quality of oil can vary depending on the intended use, while the quality of crude oil can vary depending on where it is extracted from and its density and viscosity.
Understanding the characteristics of oil and crude oil is important for investors and traders who are looking to speculate on the price of these commodities. By understanding the differences between oil and crude oil, investors and traders can make informed decisions about buying and selling futures contracts and other oil-related securities, as well as understanding their impact on the environment.
