Total, Eni and Statoil are seeking buyers for their stake in the Teesside oil terminal in northern England, which receives crude from the Norwegian Ekofisk fields.
The sale is run jointly by investment bank Rothschild and may fetch as much as $400 million, according to the sources.
Total holds a 32.9 percent stake in the terminal, Statoil a 27.3 percent stake and Eni a 10.3 percent stake. Paris Orleans holds the remaining 0.2 percent stake but it was unclear if they are taking part in the sale process.
The Teesside terminal, completed in 1975, receives, processes and stores crude oil and natural gas liquids from the Greater Ekofisk and Valhall field clusters in Norway as well as the Judy Platform in the British North Sea.
