Most people presume petroleum to be similar to gasoline or petrol, simply a less pure form, which needs to be refined. In actuality the chemical composition of petroleum in its raw state can vary extremely. This variation is the reason why petroleum composition differs so much in colour and viscosity between crude oil fields and geographical areas. Petroleum - Crude oil Composition by weight Element Percent range Carbon 83 to 87% Hydrogen 10 to 14% Nitrogen 0.1 to 2% Oxygen 0.05 to 1.5% Sulfur 0.05 to 6.0% Metals < 0.1% Composition Four different types of hydrocarbon molecules appear in crude oil. The relative percentage of each varies from oil to oil, determining the properties of each oil. Crude Oil Crude oil is a natural multicomponent mixture. Its major part is composed of hydrocarbons (alkanes, naphthenes, and aromatics). Their content in oils ranges between 30% and 100%. Most important among the non-hydrocarbon components are resins and asphaltenes. The most widely used correlations treat the oil and gas phases as a two-component system. Only the pressure, temperature, specific gravity, and relative amount of each component are used to characterize the oil’s PVT properties. Crude oil systems from various oil-producing regions of the world were used in the development of the correlations.
The oil production process begins with the removal of crude oil from local and Note: The total weight by percentage of the crude oil's composition equals more
Sulfur content of crude oils is the second most important property of crude oils next to API gravity. Sulfur content is expressed as weight percent of sulfur in oil and typically varies in the range from 0.1 to 5.0%wt. The standard methods that are use to measure the sulfur content are ASTM D129, D1552, and D2622, depending on the sulfur level. Four Mexican crude assays updated. Dominican Republic refinery exports first IMO 2020-compliant fuel. Refidomsa has exported its first shipment of low-sulfur fuel oil that complies with the IMO's On average, U.S. refineries produce, from a 42-gallon barrel of crude oil, about 19 to 20 gallons of motor gasoline, 11 to 12 gallons of distillate fuel, most of which is sold as diesel fuel, and 4 gallons of jet fuel. More than a dozen other petroleum products are also produced in refineries. Petroleum refineries produce liquids the Crude oil is a fossil fuel, and it exists in liquid form in underground pools or reservoirs, in tiny spaces within sedimentary rocks, and near the surface in tar (or oil) sands. Petroleum products are fuels made from crude oil and other hydrocarbons contained in natural gas. Petroleum products can also be made from coal, natural gas, and biomass.
Petroleum, or crude oil, is a naturally occurring liquid that originates from the Carboniferous period about 200 to 400 million years ago. Plants, ferns, trees, and algae formed peat which over millions of years turned into petroleum (crude) oil, natural gas, and coal.

Petroleum or crude oil is a complex mixture of hydrocarbons and other chemicals. The composition varies widely depending on where and how the petroleum was formed. In fact, chemical analysis can be used to fingerprint the source of petroleum. However, raw petroleum or crude oil has characteristic properties and composition.
Each crude oil has unique molecular characteristics which are revealed by the use of Crude oil assay analysis in petroleum laboratories. [citation needed] 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.

With such narrow ranges of change in elemental contents, elemental composition does not have much utility for classification of crude oil. Instead, variations in hydrocarbon composition (paraffins, naphthenes, and aromatics) are used to classify crude oils, using a ternary diagram, shown in Figure 2.2.

crude oils. The proportion of light hydrocarbons in the petroleum mixture varies greatly Crude oil varies greatly in appearance depending on its composition.
Crude oils are often classified on the basis of chemical composition, according to the proportion of hydrocarbon constituents. Paraffinic crude oils are rich in Nitrogen isotope ratios are reported relative to atmospheric nitrogen. Crude oils were analyzed by the U.S. Geological Survey (Denver, Colorado). API gravity of contents (saturates, aromatics and polar) of crude oils collected from different oil fields of North. (Punjab) and characteristics in term of chemical composition ( Roussel and Boulet However, this percentage rises to 35% in highly paraffmic. Physical Properties and Chemical Composition of Alaska North Slope Crude Oil The mass fraction of water in oil or an emulsion, expressed as a percentage, focus will be on the composition and oil. Natural processes can degrade virtually all compounds in crude oils, with to 50 weight percent of natural gas in. Crude oil is a naturally occurring, unrefined petroleum product composed of can vary in color from black to yellow depending on its hydrocarbon composition. a margin payment that covers a percentage of the total value of the contract. Many of the things derived from crude oil like gasoline, diesel fuel, paraffin wax and so on take advantage of this energy. Hydrocarbons can take on many different
