Norway’s Statoil AS A said on Monday that the giant Johan Sverdrup oil field in the North Sea could generate revenue of 1.35 trillion Norwegian kroner ($199.21 billion) over the next five decades. The Norwegian oil producer said that the oil field could produce up to 650,000 barrels of oil a day at its peak. “According to a provisional estimate, total production revenues over 50 years may amount to as much as 1,350 billion kroner,” said Statoil.
