SINGAPORE, Sept 21 (Reuters) - The Middle East crude market remained firm on Friday after Qatar sold its condensate via tender at stronger differentials than previous months, in line with a stronger spot market. Trading in the spot market was subdued and dealers said most of the cargoes had already been sold. "There are no more keen sellers in the market, so it appears that trading for the month is nearly over," said a trader with a north Asian refiner. *TENDERS - Qatar International Petroleum Marketing Co, or Tasweeq, has sold deodorised field condensate (DFC) at a $1.50 per barrel premium to Dubai quotes and low sulphur condensate (LSC) at a 50 cents per barrel discount to Dubai quotes, sources said. Tasweeq sold about 5-6 cargoes each of the two condensate grades, traders said. Shell, Essar Oil and Japanese refiner JX Nippon Oil & Energy Corp were among the buyers, they added. The deals could not be independently verified. Traders said that strong premiums in the Middle East crude market as well as lower supplies of LSC resulted in higher bids at the tender. Tasweeq had sold DFC at parity to Dubai quotes and LSC at $2 a barrel below Dubai for October loading. *TRADES: - Shell sold one November Dubai partial to Gunvor at $108.10 per barrel, while SK Energy sold one November Dubai partial to Chinaoil at $108.20 per barrel. *MARKET NEWS - Denmark's Maersk Oil is in talks with Qatar Petroleum to extend a production sharing contract for the offshore al-Shaheen oilfield by another 13 years to 2030, industry sources said on Friday. - Nigeria plans to export 380,000 barrels per day (bpd) of Qua Iboe crude oil in November, up slightly from 368,000 bpd in October, a provisional loading programme showed. - New projects should help French oil group Total confirm its 2010-2015 output target in a strategy update on Monday, although analysts will be keen to hear its big exploration budget is yielding more discoveries. - China's crude oil imports from Iran fell by nearly one-fifth year-on-year in August to about 371,000 barrels per day (bpd), a decline traders said was due to the inability of Iran's shipping fleet to cope amid sanctions.
