The Brent Сrude oil was originally produced from the Brent oilfield in the North Sea. About 2/3rds of all crude oil contracts around the globe include Brent Сrude oil, making it the most popular marker. Its relatively low density and sulphur content are the reasons why it’s described as light and sweet. One of the advantages is transportation since this type of oil is waterborne. The Brent Crude oil marker is also known as Brent Blend, London Brent and Brent petroleum and has a UKOIL ticker symbol.
