Marketmen said the rise in crude oil futures is largely in tandem with a firming trend in Asia after a mixed US energy report showed a healthy decline in crude stock but a rise in output, which could aggravate the global supply glut.
Meanwhile, the US Department of Energy said yesterday crude stockpiles in the world's top consumer slid 4.4 million barrel in the week through July 31, indicating robust demand.
But it also showed US production rising 52,000 barrels per day to 9.5 million barrels per day, rebounding from the previous week's drop.
West Texas Intermediate crude prices for delivery in September advanced two cents to $45.17 a barrel and Brent rose 11 cents to $49.70 in late-morning trade on the New York Mercantile Exchange.
