Around 0940 GMT, Brent crude for delivery in March hit $60 for the first time in 3.5 weeks and was up 20% compared with two weeks ago, prior to an oil production cut by OPEC and non-cartel producers from January 1.
After reaching $60.05, Brent cooled slightly to $59.79, up $1.07 from Tuesday's close.
Oil prices decline on oversupply, volatile markets
Brent and the world's other key contract, West Texas Intermediate (WTI), slumped late last year, hitting 18-month low points at $49.93 and $42.36 per barrel respectively.
WTI for February delivery was up $1.23 on Wednesday to $51.01 per barrel.
OPEC - a cartel of producer countries that has long manipulated output of the commodity to influence global prices in members' favour - and non-OPEC members, notably Russia, in December agreed to trim production by 1.2 million barrels a day from the start of this year to shore up sagging prices.
OPEC and its partners, which together account for around half of global output, have presided over a glut in the market which had led to oil prices tumbling by more than 30% between October and December.
