Brent crude up $1.09 on day

Crude oil prices rose on Friday but was still down over the week after Nigerian militants threatened more attacks on oil facilities there and on comments from the president of the Organization of Petroleum Exporting Countries that he supports further production cuts by the group in order to moderate supply further. OPEC meets next Thursday to consider such a move.

Brent crude for January delivery added $1.09 to $63.66 per barrel in London, while January contracts for West Texas Intermediate crude gained 86 cents to $63.35 per barrel. Brent prices dropped 1.4 percent during the week, however, while WTI lost 0.2 percent this week.

Natural gas prices were down 8.3 percent over the week to $7.725 per million British thermal units as inventories remained at record levels and US weather forecasters continued to predict that the winter will be a milder than average one.
