According to Wallstreetcn, crude price differentials from the North Sea to the Mediterranean have surged to record levels after the shutdown of a key Saudi oil pipeline jolted Europe’s physical market. Traders active in the market said Johan Sverdrup, one of the grades best suited to replace Middle Eastern crude, was quoted at a record premium of $33-$35 a barrel to front-month Brent, up from just 60 cents during Platts window trading on September 8. Traders also said Johan Castberg was quoted at more than a $30 premium, while the ultra-light CPC Blend, which is not seen as a good substitute for Middle Eastern grades, was quoted at front-month Brent plus $9, compared with less than $1 a week earlier.
