Oil prices rose in choppy trading on Friday, a day after its biggest gains in a month, as a weaker U.S. dollar helped support crude.
Baker Hughes reported that U.S. crude oil rigs rose by 15 this week, and now total 396. This time last year, there were 672 oil rigs in production, Baker Hughes said. Oil prices pared gains after the data showed the seventh consecutive week of added rigs.
Brent crude futures were up 87 cents, or 1.87 percent, to $46.90 per barrel. It was up about 5.7 percent on the week.
U.S. West Texas Intermediate (WTI) crude settled at $44.49 a barrel, up $1, or 2.3 percent - marking a three week high.
The dollar weakened after U.S. retail data showed sales were flat for July, against expectations of a modest rise. A weaker greenback makes dollar-denominated crude more affordable to holders of other currencies.
Both price benchmarks rose more than 4 percent on Thursday after Saudi Arabia's energy minister Khalid al-Falih said that oil producers would discuss potential action to stabilize oil prices during a meeting next month in Algeria.
