SINGAPORE, Feb 29 (Reuters) - The Middle East crude market held firm on Wednesday, with values for the benchmark Murban crude pegged just above 10 cents a barrel, steady to the previous session.

Saudi Aramco is due to release their official selling prices for May by March 5. *OMAN OSP - The official selling price (OSP) for Oman crude in April will rise $6.69 to $117.32 a barrel, Reuters calculations based on data from the Dubai Mercantile Exchange (DME) showed on Wednesday.

The Dubai crude OSP for May was set at a discount of 70 cents per barrel. * TRADES - SK Energy sold 10 Dubai partials to Shell and Vitol at $119.90-$120.00 a barrel. * MARKET NEWS - U.S. crude oil stockpiles likely rose last week for the second straight period on higher imports, an extended Reuters poll showed on Tuesday. - Japan's total oil product sales in January rose 2 percent from a year ago, its second consecutive month of year-on-year gains, driven by an increase in the amount of fuel oil electricity utilities bought to compensate for the lack of nuclear power.
