Investing.com - Crude prices edged lower in early action on Thursday, as concerns over a rise in U.S. oil inventories and record weekly domestic production weighed.
New York-traded WTI crude futures shed 28 cents, or roughly 0.4%, to $71.56 a barrel by 3:55AM ET (0755MT), extending losses into a third session.
It closed 50 cents lower on Wednesday, pressured by a surprise jump in weekly U.S. crude supplies.
U.S. oil inventories rose by 5.8 million barrels in the week to May 18 to 438.1 million barrels. Analysts had forecast a decline of 1.5 million barrels.

Meanwhile, Brent crude futures, the benchmark for oil prices outside the U.S., inched down 36 cents, or about 0.5%, to $79.43 a barrel.
