crude oil

Definition

Mixture of naturally occurring hydrocarbons that is refined into diesel, gasoline, heating oil, jet fuel, kerosene, and literally thousands of other products called petrochemicals. Crude oils are named according to their contents and origins, and classified according to their per unit weight (specific gravity). Heavier crudes yield more heat upon burning, but have lower API gravity and market price in comparison to light (or sweet) crudes. See also petroleum.
