Crude petroleum is mainly classified into three categories based on its density and sulfur content: light, medium, and heavy crude. Light crude has a low density and high API gravity, making it easier to refine, while heavy crude has a high density and lower API gravity, requiring more complex processing. Additionally, crude oil can be categorized as sweet or sour, depending on its sulfur content; sweet crude has low sulfur levels, while sour crude contains higher sulfur levels, affecting its market value and refining processes.
