Meanwhile, traders gauged the violence in Nigeria, Africa's biggest crude producer, where militants released two Italian oil worker hostages who were seized more than three months ago. But the militants vowed more kidnappings of oil workers and attacks on oil installations.
"We will step up our attacks against creek- and land-based installations around the delta. Car bombs will also be freely utilized within and outside the Niger Delta," the Movement for the Emancipation of the Niger Delta said, adding the freed Italians "will be replaced by other hostages who will again be taken off oil installations thought to be secure."
More than a year of stepped-up violence in the Niger Delta has cut daily output in Nigeria by nearly one quarter.
Wednesday's weekly petroleum inventories report from the U.S. show that crude oil stocks rose less than expected from the previous week. The Energy Department said crude inventories rose last week to 325.3 million barrels, up by 1.1 million barrels. Analysts surveyed by Dow Jones Newswires expected a bigger gain of 1.4 million barrels.
Gasoline inventories fell by 2.5 million barrels last week, above expectations of a 2.1 million barrel decline. Inventories for distillate stocks which include heating oil and diesel fuel fell by 2.8 million barrels, more than estimates of a 1.9 million barrel drop.

However, inventories for crude, gasoline and distillates remain at the upper end of average for this time of year, reports AP.
