Remarks by ECB chief Mario Draghi that possible additional monetary stimulus measures could come as soon as March lifted global markets and brought a measure of joy after weeks of painful losses.
At around 0320 GMT, US benchmark West Texas Intermediate (WTI) for March delivery was up five cents at USD 29.58 barrel. Brent rose 13 cents to USD 29.38.
Yesterday, Brent surged almost five per cent and WTI jumped more than four per cent after Draghi said there were "no limits to how far we are willing to deploy our policy instruments" in a signal that more stimulus could be coming.
Earlier in the week, WTI sank to as low as USD 26.19 on Wednesday before closing at USD 26.55, the lowest level since May 2003. Brent also tumbled below USD 28, to its weakest point in more than 12 years.

He cautioned against oil prices have already hit bottom.
"It's the end of the week, and for the past three weeks, the markets have wrong-footed analysts who say that we are going to see a rebound," Aw added.
BMI Research said the weakness in commodity prices since the start of the year "reinforces our view that 2016 will be another tough year for commodity markets and that a sustained recovery will remain elusive".
