Russia 's state-held energy giant OAO Gazprom (GAZP.RS) said on Friday it had launched oil production at an Arctic rig that was raided in September by 30 Greenpeace activists whom the authorities later detained.

"Gazprom has begun oil production at the Prirazlomnoye deposit," the company said in a statement. "This is the first project in
Russia 's history aimed at developing the resources of the Arctic shelf."
