SINGAPORE- Middle East crude benchmarks Oman and Dubai edged up on Thursday, underpinned by robust demand as more buying interest emerged after spot premiums slumped to multi-month lows.

Qatar Energy has sold al-Shaheen crude loading in February at the lowest premiums in 3 months, trade sources said. 

The four cargoes were sold at premiums averaging at $1.57 a barrel to Dubai quotes, the sources said, down from $3.45 a barrel for January-loading cargoes traded last month.

China's Hengli Petrochemical bought three of them while Japan's top refiner Eneos purchased one, they said. The cargoes will load on Feb. 1-2, 15-16, 25 and 26-27.

Following the tender, Qatar Energy has set the term price for February supplies of the grade at a premium of $1.62 a barrel, the sources said, down from $3.68 a barrel in the previous month.

Rongsheng Petrochemical, the trading arm of Chinese refiner Zhejiang Petrochemical, will close a tender for February spot cargoes later on Thursday.

Earlier this week, Rongsheng bought 1 million barrels each of Abu Dhabi's Upper Zakum crude and Iraqi Basra Medium crude for loading from February or March to December, trade sources said. Sellers and prices were not immediately known.

More refiners from India, Thailand and Taiwan will be buying crude over the next few days.

For Russian grades, spot premiums for February-loading Russian ESPO crude, a popular grade among China's independent refiners, slipped to the lowest in four months after Surgutneftegaz sold two cargoes, trade sources said.

The cargoes to load on Jan. 31-Feb. 5 and Feb. 3-8 were sold at about $3 a barrel above Dubai quotes, likely to Glencore, the sources said, down from premiums ranging from $5 to $6 a barrel for January-loading cargoes traded last month.

Surgut has a second tender closing on Thursday for cargoes loading on Feb. 6-13, 10-17 and 13-20.

Separately, Paramount Energy has sold two ESPO crude cargoes loading in February to Shell and Zhenhua Oil, the sources said. Prices for these cargoes were not immediately known.
