The Paris-based International Energy Agency (IEA) revised up its prediction for global oil demand this year by 50,000 barrels per day (bpd) in its monthly oil market report Friday, due to growth in leading countries.

"Global oil demand is now projected at 86.6 million bpd in 2010 and 87.9 million bpd in 2011, suggesting increments of 1.9 million bpd and 1.3 million bpd, respectively," the agency said in the report.

Though concerns that a slack global economic recovery could stall persist, members of the Organization of Economic Cooperation and Development registered a remarkable increase in oil demand, surprisingly boosting 2010 data higher, IEA said.

For yearly oil supply, the agency slightly revised upwards non-OPEC forecast for 2010 and 2011 to 52.6 million bpd and 52.9 million bpd, respectively, taking account of the impact of Atlantic storms to producers in the Gulf of Mexico in autumn.

In August, maintenance in Canada, the UK and Russia brought non-OPEC oil supply down to 52.4 million bpd, reducing global output by 250,000 bpd to 86.8 million bpd.

Global refinery crude throughputs for the third quarter this year is estimated at 74.7 million bpd, up by 0.6 million bpd over the second quarter, falling to 73.9 million bpd in last quarter of this year as global demand slows.

However, year-on-year, global refinery crude throughputs for the fourth quarter this year was higher by 1.4 million bpd than a year before, IEA added.

Benchmark oil for October delivery rose 43 cents to 78.17 U.S. dollars a barrel on the New York Mercantile Exchange when the Thursday session closed. In Singapore on Friday, the benchmark price settled at 74.77 dollars a barrel.
