The chemical profiles, or crude oil assays, specify important properties such as the oil's API gravity. The delivery locations are usually sea ports close to the oil fields from which the crude was obtained (and new fields are constantly being explored), and the pricing is usually quoted based on FOB ( free on board , without consideration of ...
Top 5 oil-producing countries 1980–2022 World oil production. This is a list of countries by oil production (i.e., petroleum production), as compiled from the U.S. Energy Information Administration database for calendar year 2023, tabulating all countries on a comparable best-estimate basis.
Petroleum [a] is a naturally occurring yellowish-black liquid mixture. It consists mainly of hydrocarbons, [1] and is found in geological formations.The term petroleum refers both to naturally occurring unprocessed crude oil, as well as to petroleum products that consist of refined crude oil.
This list of oil fields includes some major oil fields of the past and present. Countries by proven oil reserves 2017. The list is incomplete; there are more than 25,000 oil and gas fields of all sizes in the world. [1] However, 94% of known oil is concentrated in fewer than 1,500 giant and major fields. [2]
The clear cut definition of light and heavy crude varies because the classification is based more on practical grounds than theoretical. The New York Mercantile Exchange (NYMEX) defines light crude oil for domestic U.S. oil as having an API gravity between 37° API (840 kg/m 3) and 42° API (816 kg/m 3), while it defines light crude oil for non-U.S. oil as being between 32° API (865 kg/m 3 ...
In March, crude oil imports were about 7.6 million barrels per day, while products imports came to about 1.8 million barrels per day. ... For example, the major refining center on the Gulf Coast ...
Petroleum refinery in Anacortes, Washington, United States. Petroleum refining processes are the chemical engineering processes and other facilities used in petroleum refineries (also referred to as oil refineries) to transform crude oil into useful products such as liquefied petroleum gas (LPG), gasoline or petrol, kerosene, jet fuel, diesel oil and fuel oils.
Petroleum products are materials derived from crude oil as it is processed in oil refineries. Unlike petrochemicals, which are a collection of well-defined usually pure organic compounds, petroleum products are complex mixtures. [1] Most petroleum is converted into petroleum products, which include several classes of fuels. [2]
