Russia produces 11,262,746 barrels per day of oil (as of 2016) ranking 3rd in the world, which represents about one eighth of the amount of barrels of oil produced globally, which is estimated at about 88.4 million barrels per day in 2020.

We know that even if Russian oil is banned, the country may continue to export it to some countries, most notably China. Therefore, it is unlikely, at the present time, that we will witness prices above 200 dollars per barrel.
