Crude was little changed in choppy trading on Friday as investors moved to square positions after Brent posted one of its biggest weekly falls this year, on reduced concerns over exports from strife-torn Iraq.

Prices have dropped more than $2 from a nine-month high of $115.71 hit on June 19 as output from Iraq's southern oilfields - which produce most of the nation's 3.3 million barrels per day (bpd) - remained unaffected by fighting in the north and west. If fighting between Sunni militants and Iraq government forces is contained in regions north of Baghdad then the chance of supply disruptions will shrink, risk analysts said.
