A complex mixture of heavy organic compounds in crude oils that precipitate under natural conditions due to the admixture of light hydrocarbons to the reservoir or in the laboratory by addition of excess n-pentane, n-exane, or n-heptane. After precipitation of asphaltenes, the remaining oil consists of saturates, aromatics, and nitrogen, sulfur, and/or oxygen (NSO) compounds.[1]
