Crude futures in New York trading were up more than 10 per cent around 1730 GMT, a day after US prices tanked towards 13-year lows. Brent crude futures rocketed 8.5 per cent in London.
Yesterday's sharp falls "triggered some kind of bargain-hunting", said Bernard Aw, a market strategist at trading firm IG.
He added it was unlikely that price support had come from another report suggesting the OPEC producers' cartel was open to working towards cutting output .
The point was echoed by Michael McCarthy, chief market strategist at CMC Markets in Australia.

"The market will oblige all (producers) not to reduce but to stabilise their output levels," he said.
