LONDON, Feb 28 (Reuters) - Oil prices rose more than $1 per barrel on Monday as protests in Oman fuelled wider concern about security of supply from the Middle East after uprisings in Libya dramatically reduced exports from North Africa.
Saudi Arabia has increased oil production to meet any shortfall from Libya but investors are worried unrest could spread to other big oil producers such as Kuwait or Iran.
The worst-case scenario for oil markets would be an interruption to supply from Saudi Arabia itself. It holds most of the world's spare crude output capacity, and no other producer could quickly fill supply gaps.
Brent futures for April <LCOc1> rose $1.54 to $113.68 a barrel by 0850 GMT. U.S. crude <CLc1> rose $1.10 at $98.98 a barrel. Both benchmarks posted their highest weekly close in two-and-a-half years last week.
"'Fear mode' is clearly where we are right now, as investors look past Libya, and wonder whether the current unrest will sweep eastward into the oil-rich Persian Gulf nations in more dramatic and destabilising fashion," said Edward Meir, senior commodity analyst at brokers MF Global.
"Dispassionate analysis would lead us to conclude that the current surge in prices is likely overdone," Meir said, noting that Libyan oil production was less than 2 percent of world supply and its output was unlikely to be lost permanently.

OMAN
Oman is the latest producer to feel the impact of the regional unrest, although its oil flow has not been affected. Omani oil is equivalent to about 1 percent of global oil consumption and any disruption could be expected to have an impact on oil prices.
Protesters blocked roads into the industrial area of Oman's refined product export port Sohar on Monday. Product shipments continued unhindered, a port spokeswoman said.
Oman produces around 850,000 barrels per day (bpd) and its crude forms part of benchmark used to price more than 10 million bpd of crude shipped from the Middle East to Asia.
The uprising in Libya has shut in as much as three-quarters of its output of 1.6 million bpd, according to some estimates.
State oil giant Saudi Aramco has met all demand for extra supplies from Libya, Chief Executive Khalid al-Falih said on Monday. [
]The kingdom has boosted output above 9 million bpd, a senior industry source familiar with Saudi production told Reuters last week. Saudi Arabia pumped around 8.3 million bpd in January, according to a Reuters survey, although some estimates were as high as 8.9 million bpd.
Iran's oil minister urged Saudi Arabia on Sunday to refrain from taking a hasty decision on increasing its oil production after the popular uprising in Libya, the official IRNA news agency reported. [
]Still, Iran is also selling more crude to refiners looking for alternatives to Libyan supplies. [
