* Crude holds at $120 support
* Traders eye Iran's posture, Nigerian violence

TOKYO, July 31 (Reuters) - Oil prices steadied on Thursday,
after U.S. government data on Wednesday showed an unexpected
drop in gasoline stocks as suppliers facing weak consumer
demand cut production and imports, sending prices surging more
than $4.
The rebound on Wednesday came after oil prices pulled back
sharply since hitting an all-time peak above $147 on July 11,
on concerns over falling demand, especially in the United
States, the world's largest oil consumer.
U.S. light crude for September <CLc1> rose 4 cents at
$126.81 a barrel by 0738 GMT, after jumping $4.58 on Wednesday.
London Brent crude <LCOc1> eased 10 cents at $127.00 a
barrel.
"Although oil prices have fallen around $20 from their
peak, support at $120 held and that means there is the
potential for prices to rise back to record levels again," said
Shuji Sugata, manager at Mitsubishi Corp Futures and Securities
Ltd in Tokyo.
The rise came after data late on Wednesday showed a
larger-than-expected decrease in U.S. gasoline stocks last
week. []
Additional support came from refinery problems, with BP
<BP.L> cutting rates at its Texas City plant due to mechanical
problems. Top U.S. refiner Valero plans to cut gasoline
production by an average of 330,000 barrels per day (bpd) in
the third quarter at its 16 plants.
In Finland, Neste Oil's <NES1V.HE> new 750 million euro
diesel line, opened in June last year, will be shut for
maintenance for about one and a half months from second-half
August. The line has been facing teething problems and was hit
by a fire in April, hitting its operations.
The problems at the Porvoo refinery and at other plants in
northern Europe have left the region's diesel market short of
supply in recent months. []
IRAN, NIGERIA EYED
The plunge in oil since hitting a record of $147.27 on July
11 is the steepest drop from a high since early 2007. Oil was
hit by signs that costly fuel and wider economic problems were
curbing demand.
Strong growth from emerging economies such as China has
stretched poor supply growth over the past six years, launching
a rally that sent crude up sevenfold at its peak.
Further strength has come from investors buying commodities
as a hedge against inflation and the weak dollar, tensions
between Iran and the West, and supply disruptions.
Iran will press ahead on its nuclear path, the country's
highest authority, Supreme Leader Ayatollah Ali Khamenei, said
on Wednesday, speaking just before a deadline set by Western
officials in a nuclear dispute.
Western powers gave Iran two weeks from July 19 to respond
to their offer to hold off on imposing more U.N. sanctions on
Iran if Tehran would freeze any expansion of its nuclear work.
Rival militant factions in Nigeria's oil-producing Niger
Delta have clashed in an apparent turf war, killing at least
four people, security officials said on Wednesday.
Militant attacks have disrupted supplies from the OPEC
nation this year, helping to push up oil prices.
A bill aimed at preventing excessive speculation in oil and
other futures trading did not get enough votes to pass in the
U.S. House of Representatives on Wednesday, as Republicans
complained the measure did not also open more offshore areas to
oil drilling.
