Brent crude futures rose $2.48, or 2.27 percent, to $111.81 a barrel, after falling 1.6 percent in the previous session, according to "Reuters".
West Texas Intermediate (WTI) crude futures rose $2, or 1.89%, to $108.02 a barrel, after a 2.5% drop on Thursday.
And in a week of volatile trading marked by talk of a Russian oil embargo and then potential supply additions from Iran, Venezuela and the United Arab Emirates while fighting escalated in Ukraine, Brent crude was on course for a 5.2% weekly drop after hitting a 14-year high.
Prices fell this week after it became clear that the European Union, which relies heavily on Russian energy, would not join the United States and Britain in banning Russian oil.
Russia, the world's second largest crude oil exporter after Saudi Arabia, exports about 3 million barrels per day of crude to OECD countries in Europe.
