US benchmark West Texas Intermediate (WTI) for April delivery rose 10 cents to USD 49.38 a barrel.
Brent North Sea crude for April climbed 25 cents to stand at USD 58.91 a barrel in London midday deals.
Crude futures had also fallen yesterday as traders estimated a key report will show another increase in US crude inventories that already are at record levels.
Prices also sank this week as traders worried about abundant global supplies alongside slower economic growth, with no sign of a slowdown in rising US crude stockpiles.
Later today, the US Department of Energy will release the official stockpiles report for the week to February 20.
Crude oil stockpiles are expected to have risen by 3.75 million barrels last week, according to analysts polled by Bloomberg News.
That would add to the 425.6 million barrels in stockpiles that were reported last week.
"The market is still oversupplied, and US oil production continues to grow unperturbed," said Commerzbank analysts.
"Unless it drops to below nine million barrels per day, we do not expect this oversupply issue to end," Ang said.
The market was also digesting US President Barack Obama's decision on Tuesday to veto legislation allowing the Keystone XL oil pipeline to be built between Canada and the US.
The 1,900-kilometre TransCanada-built pipeline would transport crude from energy-rich Alberta to a network of pipelines that reach across the US to the shores of the Gulf of Mexico.
The project has in recent years pitted environmental groups against the oil industry, which has argued that it will bring much-needed jobs to the United States and help it achieve energy self-sufficiency.
