Oil prices fell on Friday, as a stronger dollar pulled crude off the 2016 highs hit this week, although strong refinery demand and global supply disruptions lent some support.
International Brent crude oil futures were trading at $51.45 per barrel at 0655 GMT, down 80 cents, or around 1 percent, from their last settlement. U.S. West Texas Intermediate (WTI) futures were down 57 cents at $49.99 a barrel.
