SINGAPORE, Nov 2 (Reuters) - The Asia-Pacific crude market remained weak on Friday, pressured by an oversupply of Far East Russian crude and weak demand. Russian ESPO blend crude was transacted at a premium of about $1.90-$2.80 a barrel to Dubai quotes, the lowest levels at which the crude has traded in about two years, traders said. Russia has increased ESPO crude exports to Asia after completing a pipeline expansion, but demand was lacklustre as most of the Asian refiners have completed their purchases for December while the arbitrage window to the U.S. West Coast was closed. TENDERS: - Royal Dutch Shell has bought a third of the Russian ESPO crude supply in December at the lowest premiums in two years, traders said on Friday. Shell bought four cargoes from Surgutneftgaz and two cargoes from Rosneft at premiums ranging from $1.90 to just above $2.80 a barrel to Dubai quotes, traders said. The spot premium for ESPO last hit a low of about $2 above Dubai quotes for cargoes loading in December 2010, according to Reuters data. - Indian state-run explorer Oil & Natural Gas Corp sold one cargo of Russian Sokol crude for January at a similar premium from the previous month, reflecting firm demand for the distillates-rich grade. The 700,000-barrel cargo was sold to European trader Vitol at a premium of $8.48 a barrel to Oman/Dubai quotes. ONGC last sold a December cargo to BP at about $8.40 a barrel above Oman/Dubai quotes. * MARKET NEWS - U.S. oil major Chevron said on Friday its Angolan subsidiary, Cabinda Gulf Oil Company, had declared force majeure at the Kuito offshore oil terminal on October 29, without giving a reason. - JX Nippon Oil & Energy Corp, Japan's top refiner, will stop processing crude at its 180,000 barrels-per-day (bpd) Muroran refinery in northern Japan at the end of March 2014 to help meet government rules on capacity. - Increased production by Rosneft helped to lift Russia's oil output by 0.5 percent in October to a post-Soviet high of 10.46 million barrels per day (bpd), data showed on Friday.
