Naphthenes: Cyclic saturated hydrocarbons that contribute to the density and energy content of the oil. Sour crude contains more than 0.
Crude Oil Paraffins Aromatics and Solvents Breakdown
Unsaturated hydrocarbons, which include alkenes and alkynes, contain double or triple bonds, making them more chemically reactive and valuable for producing high-octane gasoline components. The sulfur content, as mentioned, classifies oil as either sweet or sour, influencing refining complexity and environmental compliance requirements.
These hydrocarbons form through the decomposition of ancient plankton and algae buried under layers of sediment over millions of years. Aromatics: Ring-structured hydrocarbons that are often associated with higher octane ratings but can be environmentally problematic.

Unsaturated Compounds Beyond the structural classification, hydrocarbons in crude oil are also distinguished by their saturation levels. Oxygen Compounds: Including resins and acids, these oxygen-containing molecules contribute to the acidity of some crude oils.
