Sour crude oil is crude oil containing a high amount of the impurity sulfur. It is common to find crude oil containing some impurities. When the total sulfur level in the oil is more than 0.5% (by weight), the oil is called "sour". [1] The impurities need to be removed before this lower-quality crude can be refined into petrol, thereby ...
Although crude oil assays evaluate various chemical properties of the oil, the two most important properties determining a crude's value are its density (measured as API specific gravity) and its sulphur content (measured per mass). Crude oil is considered "heavy" if it has long hydrocarbon chains, or "light" if it has short hydrocarbon chains ...
For example, Ekofisk, Oseberg, and Troll crude oil grades have a quality premium over Brent crude oil grades, while Forties have a price discount for high sulphur content. Brent prices usually reflect the cheapest or the most competitive physical crude oil in the above basket, which means that Brent prices usually reflect prices for Forties ...
Petroleum containing higher levels of sulfur is called sour crude oil. [3] In the Annual Energy Outlook crude type estimates, all Alaska and Gulf of Mexico oil production is assumed to be API gravity 27-35 degrees and medium sour. Northeast crude oil production consists of approximately 30% API 27-35 medium-sour and 60% API 35-40 sour.
A benchmark crude or marker crude is a crude oil that serves as a reference price for buyers and sellers of crude oil. There are three primary benchmarks, West Texas Intermediate (WTI), Brent Blend , and Dubai Crude .
Western Canadian Select (WCS) is a heavy sour blend of crude oil [1] that is one of North America's largest heavy crude oil streams [2] and, historically, its cheapest. [3] It was established in December 2004 as a new heavy oil stream by EnCana (now Cenovus), Canadian Natural Resources, Petro-Canada (now Suncor) and Talisman Energy (now Repsol Oil & Gas Canada). [4]

Dubai Crude is generally used for pricing Persian Gulf crude oil exports to Asia. The Dubai benchmark is also known as Fateh, used in the United Arab Emirates. [1] Forward trade of Dubai Crude is limited to one or two months. Dubai Crude is a medium oil. It has a gravity of 31° API (specific gravity of 0.871) and a sulfur content of 2%/weight. [2]
