Oil edges higher

Prices capped by news US output expected to rise this year

Oil edged up on Wednesday, lifted by reports of Saudi supply cuts to Asia, but prices were prevented from rising further over a lack of detail of these reductions and because of signs of rising supplies from other producers.

Prices for Brent crude futures, the international benchmark for oil prices, were trading at $53.75 per barrel early on Tuesday, up 11 cents from their last close.

US West Texas Intermediate crude futures were at $50.97 a barrel, 15 cents above their last settlement.

Traders said that the price rises were a result of reports that Saudi Arabia, the world's top oil exporter, was telling some Asian customers that it will curb crude supplies slightly from contracted volumes in February, although Reuters was not able to confirm any details of the reductions.

There were also doubts that the overall cuts would go deep enough to rebalance a market suffering from oversupply for the past two years. Both Brent and WTI futures are down about 6% since the start of the year.

"Traders continued to fret about rising US supply and compliance by Opec to agreed-upon production cuts," ANZ bank said.

The US Energy Information Administration (EIA) said on Tuesday that American crude production in 2017 would rise by 110,000 barrels per day to 9 million bpd.

Another concern for traders were high US crude stockpiles, with the EIA scheduled to release its latest figures on Wednesday.

"With inventories at the highest seasonal level in three decades, another increase in this week's report could see prices come under further pressure," ANZ said.

Outside the US, there were lingering doubts over compliance with planned production cuts from members of Opec.

Opec's second-biggest producer Iraq plans to raise crude exports from its southern port of Basra to an all-time high in February, keeping shipments high even as Opec production cuts take effect this month.

Iraq State Oil Marketing Company (Somo) plans to export 3.641 million bpd of crude in February, according to trade sources and preliminary loading schedules, potentially beating a record of 3.51 million bpd from December.

Some cuts, however, are happening. In non-Opec member Russia, which also agreed to cut output, extreme cold as low as minus 60 degrees Celsius has helped to knock out production by around 100,000 bpd in the first few days of January, and many oil engineers expect more reductions as production facilities struggle to cope with the extreme conditions.
