This morning, New York crude oil futures WTI rose by 1.86% to $ 47.18 per barrel and crude oil futures for Brent rose 1.61% to $ 48.52 per barrel. Thus, the black gold appreciates, on the background of a strike in Norway, which may lead to a reduction in production of the largest oil producer in Western Europe. At the same time Britain's decision to withdraw from the European Union is still putting pressure on the markets. Production of oil increased in Nigeria about 1.9 million barrels per day from 1.6 million, after the repair of pipelines.
