Oil falls below $136 as Nigeria strike averted

SINGAPORE (Reuters) - Oil fell on Thursday as supply concerns in Nigeria eased after the oil ministry prevented a potentially crippling strike by workers at Chevron.

But falling U.S. oil stocks and comments from the White House that Saudi Arabia was unlikely to raise output in the near term would support prices, which have climbed 40 percent this year.

U.S. crude fell 73 cents to $135.95 a barrel by 0558 GMT, after settling up $2.67 at $136.68 a day ago on the Nigerian worries. London Brent crude slid 66 cents to

$135.78.

Nigeria's oil ministry intervened at the eleventh hour on Wednesday to avert a strike at Chevron (CVX.N), saying it had persuaded the firm to reduce its expatriate workforce.

A senior oil workers' union had accused Chevron of having too many foreign staff, and a strike could have slashed output from the world's eighth-biggest oil producer.

But some support came after comments from the White House, which said it was not expecting Saudi Arabia to announce an output hike when producers and consumers meet in the kingdom on June 22 to address soaring oil prices.

"I think people are still in a wait-and-see situation for crude. We are in a ranged market today," said Marc Lansonneur, Societe Generale's head of commodities derivatives in Asia, adding prices were bound within the $132-$140 range.

A surge in speculative buying by investors hedging against inflation and a weak dollar has accelerated oil's rally this year.
