Why is petroleum called crude oil

Petroleum, (from Greek πέτρα - rock and έλαιο - oil) also called crude oil, is a thick and black liquid. It is a natural material mainly made of hydrocarbons. Most petroleum is found by drilling down through rocks on land or off-shore on the continental shelf. 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. When petroleum comes straight out of the ground as a liquid it is called crude oil if dark and viscous, and condensate if clear and volatile. When solid it is asphalt, and when semi-solid it is tar. There is also natural gas, which can be associated with oil or found alone. Crude oil comes in many forms. It is called crude oil mainly because 1) It has not been refined into good, usable oil (for cars and such) 2) The density of the crude oil is always different. There is no standard for something to Oil refinery or petroleum refinery is an industrial process plant where crude oil is transformed and refined into more useful products such as petroleum naphtha, gasoline, diesel fuel, asphalt base, heating oil, kerosene, liquefied petroleum gas, jet fuel and fuel oils.

Petroleum, complex mixture of hydrocarbons that occur in Earth in liquid, gaseous, or solid form. The term is often restricted to the liquid form, commonly called crude oil, but, as a technical term, petroleum also includes natural gas and the viscous or solid form known as bitumen, which is found in tar sands.

Petroleum describes not only the mixture of hydrocarbons in crude oil, The sand (or other solid materials) are called proppants and are added to prop open 24 Feb 2019 Petroleum is a broad term that groups together a combination of organic liquids Crude oil itself is a complex mixture of hydrocarbons, so the exact and force of gravity cause these accumulations - called reservoirs - to lie Note: Percentages refer to the share of US in global petroleum production. Thus, the transmission of nominal crude oil price changes to pump prices expressed in real US The realism of such scenarios raises many critics from the so-called 16 Dec 2010 Why is it called petroleum jelly when it is made with petrolatum and not some oil?

Petroleum—or crude oil—is a fossil fuel that is found in large quantities beneath the Earth's surface and usually found in underground areas called reservoirs.

The name petroleum covers both naturally occurring unprocessed crude oil and in them are more fluid than in Canada and are usually called extra heavy oil.

The oil we find underground is called crude oil. Crude oil is a mixture of hydrocarbons - from almost solid to gaseous. These were produced when tiny plants and Crude oil and natural gas are mixtures of hydrocarbons-chemical molecules that The term "petroleum" collectively refers to crude oil, natural gas and solid This involves a process called fractionation in a series of columns, where the NGL 14 Nov 2019 Crude oil is a mixture of many different organic compounds called called refining into the types of petroleum products (gasoline, diesel,

Petroleum containing higher levels of sulfur is called sour crude oil . Sweet crude oil contains small amounts of hydrogen sulfide and carbon dioxide. High-quality, low-sulfur crude oil is commonly used for processing into gasoline and is in high demand, particularly in industrialized nations.

Petroleum (from Latin petra – rock and oleum – oil), crude oil, sometimes colloquially called black gold, is a thick, dark brown or greenish flammable liquid, Petroleum, often known as oil, is a fossil fuel. Petroleum is called a nonrenewable People have used naturally available crude oil for thousands of years.
