Oil prices lost some sizzle after a stronger-than-expected US energy stockpiles report offset geopolitical tensions centered on the oil-rich Middle East.
New York's main futures contract, light sweet crude for delivery in November, dipped 21 cents to settle at $87.40 per barrel, the first close lower after six straight sessions of rising prices.
The New York contract earlier spiked to a new high of $89 in intraday trade, just after the Turkish parliament approved military raids against Kurdish PKK rebels based in oil-rich northern Iraq.
In London, Brent North Sea crude for December delivery shed 66 cents to close at $82.89 per barrel, after earlier hitting an intraday peak of $84.43.
