NEW YORK -Oil prices were little changed on Friday but headed for a weekly gain, as Middle East tensions and disruptions to oil output offset concerns about the global economy.
Brent futures were up a cent to $79.11 a barrel at 11:41 a.m. (1641 GMT). U.S. West Texas Intermediate crude fell 9 cents to $73.99.
For the week, the U.S. benchmark is on track to rise about 2% while Brent is set to gain about 1%.
