The giant Johan Sverdrup field contains so much oil that it could, combined with coming fields off the coast of Brazil, have a noticeable impact on the global tanker market, according to a new analysis performed by Wood Mackenzie.

The analysis shows that the fields in Norway and Brazil will add no less than 3.8 million barrels of oil to the market when the fields, according to plan, are fully operational in 2025. This will result in significantly increased volumes of heavy oil, of somewhat uniform quality, which will need to be refined - and this will create a major need for transport.
