Physical Brent crude oil represents the commingled crude from Brent and Ninian systems. The API of Brent is usually estimated at 38 degrees and the sulphur content is 0.45%. Why BLCO is high in demand all over the world: In comparison to the common Brent mix, BLCO 8% lighter and has three times less sulphur making it the most sought after crude oil in the world. Now when you consider that BLCO is 8% lighter than Brent and has one third the sulphur content then you realize a much higher percentage of BLCO will yield fuels used regularly in industrialized countires before processing is required. This makes it the low refinig cost, best fuel in the world for producing petrol [automobile gasoline],diesel [truck and auto fuel], kerosene [jet fuel & cooking oil] - all the fuels in high demand in industrialized countries.
