Oil production from the Organization of Petroleum Exporting Countries 
fell last month as higher Saudi output failed to offset a West African 
drop. 
  According to a Dow Jones Newswires survey of industry sources 
and analysts, crude-oil production from the group averaged 31.669 
million barrels a day in September, down about 166,000 barrels a day 
from 31.835 million barrels a day in August. 
  The decline in production was largely driven by lower 
production in Angola and Nigeria, which a boost in Saudi output was 
unable to offset. 
  Production in Angola and Nigeria, which have struggled to sell
 high-quality crude that carries strong premium compared to others, 
respectively fell by 97,000 barrels a day and by 92,000 barrels a day. 
By comparison, Saudi Arabia increased production by 60,000 barrels a 
day. 
  Venezuela's output was also down by 60,000 barrels a day, 
likely because an outage at the country's largest refinery, the Amuay 
complex, prompted a temporary reduction in production, Vienna-based 
consultancy JBC said in a note. The declining production "should favour 
oil prices," Commerzbank said in a note Monday. But the German bank said
 that "once oil production in Angola and Nigeria returns to normal 
levels...output should increase again."
