Sverdrup

The war “has changed the political sentiment,” said Ulf Sverdrup, the director of the Norwegian Institute of International Affairs, a research organization.

European demand for the medium-heavy Sverdrup crude, similar to Russian Urals, has increased following Moscow's February invasion of Ukraine as many European buyers voluntarily ditched Russian barrels.

Norway also plans to ramp up output from Western Europe's largest oilfield, Johan Sverdrup, in December.

Since the start of Russia's invasion of Ukraine, however, Sverdrup's flows to China have dried up, while those to Europe have more than doubled.

He found at least two permanently shadowed craters that were overlapped by these anomalies, the Sverdrup and Shoemaker craters, and there are likely more.
