SINGAPORE, Sept 5 (Reuters) - Expectations of higher official selling prices for Saudi Arabia, the United Arab Emirates and Qatar strengthened the Middle East crude market on Monday. Limited imports of Atlantic Basin crude into Asia and rising exports from the Mideast Gulf to the Mediterranean of grades including Oman and Iraqi Basrah Light reasserted the bullish tone ahead of November trade. Traders valued benchmark Oman crude cargoes for loading in November at a three-month high of about $1 a barrel above Dubai quotes, unchanged from Friday, and up from a premium of about 75 cents for the last deals heard for October cargoes. Top oil exporter Saudi Arabia may increase official selling prices (OSPs) of October crude for Asian clients, as refiners across the continent process more, aiming to benefit from attractive margins for products from fuel oil to jet fuel. All seven traders participating in a Reuters poll expect the price of Arab Light will rise, with gains expected in a range between 15 and 80 cents to a premium of between 90 cents and $1.55 a barrel to the average of Oman and Dubai quotes. The Saudi OSPs are likely to be announced later on Monday. Once the OSPs are out, Saudi Aramco is likely to notify customers in Asia later this week that their October crude supply would remain unchanged at full volumes. India's MRPL has bought 600,000 barrels extra Saudi oil for October as it did not purchase any spot cargoes in tenders seeking sweet crude for October and November. Industry functions in Singapore during the Asia-Pacific Petroleum Conference this week were expected to delay trade until the second half of the week. * EAST-WEST - The Brent/Dubai Exchange of Futures for Swaps (EFS) for October rose 9 cents to $5.15 a barrel at 0830 GMT, Reuters data showed.
