Oil dipped on Wednesday, weighed down by ongoing high supplies despite an OPEC-led production cut, but the prices remained within a narrow trading band that has been in place since late January.
Brent crude futures, the international benchmark for oil prices, were trading at $55.44 per barrel at 0423 GMT, down 14 cents from their last close.
US West Texas Intermediate (WTI) crude futures were at $52.74 a barrel, down 7 cents.
Traders said a reported rise in US crude inventories was putting pressure on prices.
“The release of the American Petroleum Institute’s crude inventories at a much higher than expected 5.8 million barrels saw both Brent and WTI quickly give back... gains,” said JeffreyHalley, senior market analyst future brokerage OANDA in Singapore.
The API data showed that commercial US crude inventories now stood at 488 million barrels.
Swelling US supplies are being countered by an effort by the Organization of the Petroleum Exporting Countries (OPEC) to prop up the market and end a global fuel supply glut.
As part of this, OPEC has said it will cut production by around 1.2 million barrels per day (bpd) in the first half of 2017. Other producers, including Russia, have pledged to cut another 600,000 bpd in output.
A Reuters survey published on Tuesday showed that OPEC’s output fell by over 1 million bpd in January to 32.27 million bpd between December and January.
“That’s a good start ... to cut production to bring the market back toward balance,” said Greg McKenna, chief market strategist at futures brokerage AxiTrader.
But McKenna added that there were still “some questions about whether or not OPEC will achieve its goals” to cut even deeper and for the full period of the first half of 2017.
With uncertainty over the final outcome of OPEC’s cuts, and little known so far about Russia’s commitments to its supply reductions, crude futures have been range-bound.
Crude has traded within a $2 per barrel range over the past week, and within $1.25 a barrel since Monday.
Reuters’ technical commodity analyst Wang Tao said that both Brent and WTI price signals were mixed, with bullish and bearish drivers largely offsetting each other.
