Oil prices advance

World oil prices rose slightly on Wednesday as traders awaited the latest weekly snapshot of US energy inventories, analysts said.
New York's main contract, light sweet crude for delivery in December, added 30 cents to 79.35 dollars a barrel.
Brent North Sea crude for December delivery gained 41 cents to 77.91 dollars per barrel in London trading.
The US government's Department of Energy will later publish a report on American crude oil stockpiles for the week ending November 6.
