SINGAPORE, March 11 (Reuters) - Brent crude fell to below $115 on Friday on easing fears of unrest spreading in Saudi Arabia, the world's top exporter, as a quite start to the planned "day of rage" pushed prices down.
ICE April Brent crude fell 55 cents to $114.88 at 0605 GMT. It touched a 2-1/2-year high of $119.79 a barrel on Feb. 24 as unrest flared in Libya disrupting oil output.
On the New York Mercantile Exchange, U.S. crude for April delivery fell 79 cents to $101.91, after briefly falling by more than $1.
"We are getting a much needed correction, unless this day of rage really explodes, the momentum is on the downside," said Tony Nunan, a risk manager with Tokyo-based Mitsubishi Corp.
"I think it's gone a little bit too far. Eventually it should go to $90 for WTI and $100 for Brent."
Investors were waiting to see signs of unrest in the world's top oil exporter that mirror events in North Africa.
Saudi police fired in the air to disperse protesting Shi'ites on Thursday, and three people were injured in the melee on the eve of a "Day of Rage" called for on social media, witnesses and activists said.
The unrest in the Middle East is taking precedence over economic woes. Friday protests are also planned in other Gulf countries such as Yemen, Kuwait and Bahrain, after the day's religious prayers, inspired by upheavals in Tunisia and Egypt.
The influence of Libya's conflict on the oil market would probably diminish in coming days because traders had discounted the loss production from what used to be the world's 12th-largest oil exporter, ANZ's Lim said.
"It's likely that Saudi Arabia will take centre stage," said Serene Lim, an oil analyst at ANZ in Singapore. "It's a foregone conclusion that Libya is in a state of civil war."
Forces loyal to Libyan leader Muammar Gaddafi have entered the oil port of Ras Lanuf in the east of the country and are fighting insurgents for control of the town, rebels said on Friday.
Libyan rebels have lost momentum and are not likely to dislodge Muammar Gaddafi from power, top U.S. intelligence officials said on Thursday as Washington backed further away from military action.
Gaddafi's son told rebels they faced a full-scale assault to crush their three-week-old uprising as forces intensified their counter-attack on the insurgent heartland, bombarding rebel positions in the oil port of Ras Lanuf and Brega, another rebel-held oil hub further east.
"As other countries, e.g. Iraq and Iran have shown, (oil) operations are usually resilient against all but the most devastating attacks and some resumption of output and processing is likely once the conflict leaves the locality of the facilities," said JP Morgan analysts headed by Lawrence Eagles.
IMPACT ON ECONOMIES
Japanese Economics Minister Kaoru Yosano said on Friday oil price rises are likely to have a substantial negative impact on global economy.
Euro zone leaders are set to agree a "competitiveness pact" at a summit on Friday and will push Portugal to announce new reforms to boost market confidence as they seek to draw a line under the debt crisis.
Although unrest in the Middle East is adding a fear premium to prompt spot U.S. crude, there appears to be no end to a contango that has existed for over two years. And rising oil prices seem to be having a limited effect on consumption in China.
China's refineries processed crude at a record rate in February, official data showed on Friday, as the world's second-largest oil consumer churned out more fuel to power irrigation work in drought-hit areas.
China's implied oil demand increased 10.3 percent from a year earlier to 9.54 million barrel per day in February, the second highest on record, Reuters calculations showed based on official data on Friday.
Eyes will also be on the impact of China's fight against inflation, with data published on Friday lending credence to the view that it is more than midway through a sustained campaign of monetary tightening launched nearly half a year ago.
