BEIJING, Sept 17 (Reuters) - Global oil prices edged up from early losses on Monday despite assurances from Washington that Saudi Arabia, Russia and the United States can raise output fast enough to offset falling supplies from Iran and elsewhere.
U.S. Energy Secretary Rick Perry said in an interview with Reuters on Friday that he does not foresee any price spikes and that the countries, the world's top three oil producers, can between them raise global output in the next 18 months.
Brent crude oil futures gained 25 cents to $78.34 per barrel as of 0727 GMT, reversing a 0.2 percent loss earlier in the session.
