Per the "Regions and crude types" discussion above, California production is categorized by its own crude type. Sweet crude oil contains small amounts of hydrogen sulfide and carbon dioxide. High-quality, low-sulfur crude oil is commonly used for processing into gasoline and is in high demand, particularly in industrialized nations.
The WTI oil grade is also known as Texas light sweet. Oil produced from any location can be considered WTI if the oil meets the required qualifications. [2] Spot and futures prices of WTI are used as a benchmark in oil pricing. This grade is described as light crude oil because of its low density and sweet because of its low sulfur content.

(Source: Marshall, 1921) Pennsylvania Grade Crude Oil is a type of sweet crude oil (sweet crude oil), found primarily in the Appalachian basin in the Marcellus Formation in the states of New York, Pennsylvania, Ohio, and West Virginia, and takes its name for the state of Pennsylvania, where it was first ...

Crude oil is most commonly organised into four types - light, heavy, sweet, and sour. [6] Petroleum is a non-renewable energy source (also known as a " fossil fuel "), so the efficacy of extraction and refining is important for its continued use; multiple techniques are used to detect and to extract crude oil, based on the source rock it is ...
For refineries, the interest has been primarily focused on the distribution between the distillation fractions: petrol, paraffin, gas oil, lubricant distillate, etc. Refiners look at the density of the crude oil – whether it is light, medium or heavy – or the sulfur content, i.e. whether the crude oil is “sweet” or “sour”.
Since sour crude is more common than sweet crude in the U.S. part of the Gulf of Mexico, Platts has come out in March 2009 with a new sour crude benchmark called "Americas Crude Marker (ACM)". [3] Dubai Crude and Oman Crude, both sour crude oils, have been used as a benchmark (crude oil) oil marker for Middle East crude oils for some time.
