The specific gravity and sulfur content are critical metrics used to classify it into light, sweet, heavy, or sour categories, which directly influence its market value and refining difficulty. While primarily consisting of hydrogen and carbon, it contains hundreds of different hydrocarbons along with trace amounts of sulfur, nitrogen, oxygen, and metals.
The high carbon content of these hydrocarbons makes their combustion a significant source of greenhouse gas emissions. In many mature fields, tertiary recovery or enhanced oil recovery (EOR) methods, such as steam injection or chemical flooding, are necessary to extract the maximum amount of hydrocarbons from the subsurface.

Formation and Geological Origins Understanding the description of crude oil requires looking back millions of years to the remains of ancient marine microorganisms. Furthermore, the presence of sulfur and other impurities necessitates stringent refining processes to meet environmental regulations and reduce pollutants like sulfur dioxide.
