Oil prices slipped on Friday, weighed down by concerns about economic recovery after U.S. jobs data showed the unemployment rate at a 26-year high.

U.S. crude fell 50 cents at $67.46 a barrel by 11:17 a.m. EDT.

London Brent crude dropped 97 cents to $66.15.

The U.S. Labor Department reported that the unemployment rate jumped to 9.7 percent in August, despite fewer job losses than expected.

The August nonfarm payrolls number was certainly better than expected but there isn't much to cheer in a 9.7 percent unemployment rate, said Mike Fitzpatrick, vice president at MF Global in New York.

I think we will take our cue from the stock market, but I don't expect much unwinding ahead of a long weekend, with the underlying concerns about the banking sector still out there, said Phil Flynn, analyst at PFGBest Research in Chicago.

U.S. crude prices have been trading in a range between $65 to $75 a barrel since the start of August, with prices varying on economic data as investors seek clues about the speed of a recovery from the recession.

Prices are nearer to recent highs and will probably not reverse to lows seen earlier in the year, Mike Fitzpatrick, vice president at MF Global in New York, said in a note.

Oil dropped below $33 a barrel in December as slumping oil demand sent crude tumbling from a high near $150 in July 2008.

Traders are also watching for clues about whether the Organization of the Petroleum Exporting Countries will change its output policy when it meets next week in Vienna.

High oil inventory levels in many consuming countries have been a concern for OPEC members. Still, most analysts expect the producer group, the source of more than a third of the world's oil supply, will agree to maintain its official output target to keep prices stable around $70.

Oil demand and supply data reviewed by a panel of OPEC economists ahead of the September 9 meeting indicate no need for a change in output policy, two OPEC delegates said on Friday.
