Oil prices eased in Asia today, with the under-pressure commodity sitting around 12-year lows as dealers prepare for the return of Iranian exports on to the market while US stockpiles increase.
However, there is talk that crude -- which have plunged by three quarters in the past 18 months on weak demand, a slow global economy and an oversupply crisis -- could be nearing its bottom.
US benchmark West Texas Intermediate (WTI) for delivery in February was down 52 cents, or 1.67%, at $30.68 by around 0435 GMT and Brent for March was down 22 cents, or 0.71%, at 30.66.
This week both main contracts fell below $30 a barrel for the first time since the first half of 2004.
Michael McCarthy, chief market strategist at CMC Markets in Sydney, said prices may have hit or are nearing the end of their downward spiral.
"If we're not at the lows, we're very close to the lows for oil," he said.
"I do expect to see a turn very soon. However, it is not uncommon to see a market near its lows to have a last final spike so I wouldn't rule that out... It is possible that we're now looking at a floor forming."
Two weeks into 2016, oil prices have had shed more than 15% as investors worry about the prolonged oversupply crisis and weak global economic outlook, particularly in chief energy user China.
However, with major producer Iran poised to return to the international market after Western-back nuclear sanctions are lifted, there are fears the losses could mount.
The implementation of a deal between the two sides, allowing the removal of sanctions, is expected by Sunday.
"Although both WTI and Brent seem to be generating some bullish momentum, we believe that it may not last," said Daniel Ang, an analyst with Phillip Futures in Singapore.
