 LONDON, Sept 2 (Reuters) - Oil slid to around $108 a barrel
on Tuesday after early reports showed Hurricane Gustav had
spared major U.S. Gulf oil facilities.
                                
 U.S. crude <CLc1> was $107.96 a barrel by 1051 GMT, down
$7.50 from Friday's close. It touched a session low of $105.46,
its lowest since April 2.
                                
 A U.S. public holiday on Monday meant the New York
Mercantile Exchange did not issue an official settlement price
for U.S. crude on Monday.
                                
 London Brent crude <LCOc1> was down $2.56 at $106.85.
                                
 As the hurricane was downgraded to a tropical storm, the
market refocused on bearish factors including a softer global
economy, weaker demand for oil and a stronger U.S. dollar.
                                
 These had already begun to drive prices down from a peak of
$147.27 a barrel hit on July 11.
                                
 Hurricane Gustav, combined with Russia's conflict with
Georgia, which disrupted flows of oil and gas, had halted the
slide.
                                
 "If it were not for these threats, we would have
been testing $100 already," said Mike Wittner of Societe
Generale.
                                
 An upturn in the dollar, plus falls in oil demand in the
United States and China, the world's top two energy consumers,
look set to exert further pressure on the market.
                                
 The weak dollar contributed to oil's surge this year as
investors turned to oil as a hedge. The U.S. currency has shown
signs of bottoming out and hit a 10-month peak against a basket
of currencies on Tuesday. [nTKW003004]
                                
 "Economic woes and the dollar strength will help oil move
down. It's highly likely to go below $100," said Christopher
Bellew of Bache Commodities Limited.
                                
 
                                
 LIMITED DAMAGE
                                
 Early checks by some U.S. refiners reported no damage from
Gustav, which had originally been classed as the biggest threat
to the U.S. Gulf oil sector since devastation from Hurricane
Katrina in 2005.
                                
 Some 1.3 million barrels per day of offshore oil production
and some 2.67 million bpd of refining capacity was shut because
of the storm. [nN01303386]
                                
 The Gulf is home to a quarter of U.S. oil output and more
than a third of U.S. refining capacity.
                                
 Louisiana Governor Bobby Jindal said on Monday that Exxon
Mobil Corp <XOM.N> would ask for crude oil from the U.S.
emergency supply on Tuesday and Shell Oil Co <RDSa.L> was
expected to make a similar request. [ID:nN01338620]
