| [DSPR]: Unrefined liquid petroleum, ranging in gravity from 9° API to 55° API and in color from yellow to black. May have a paraffin, asphalt, or mixed base. If the oil contains a sizable amount of sulfur or sulfur components, it is called a sour crude; if it has little or no sulfur, it is called a sweet crude. In addition, crude oil may be referred to as heavy or light, according to API gravity, the lighter oil having the higher gravities. |
| [GPA]: A fossil fuel formed from plant and animal remains many million of years ago. It comprises organic compounds built up from hydrogen and carbon atoms and is, accordingly, often referred to as hydrocarbons. Crude oil is occasionally found in springs or pools but is usually drilled from wells beneath the earth's surface. |
