In this Thursday, March 24, 2011 Photo, an illegal oil refinery is seen in Ogoniland, outside Port Harcourt, in Nigeria's Delta region. Shell flew journalists in a helicopter over a cleared area in the delta where locals ran makeshift refineries turning stolen crude tapped from pipelines into diesel and kerosene. The company blamed nearly all of its oil spills in 2009 on sabotage from thieves and militants. Environmentalists and community activists routinely blame Shell for the spills, pointing at the company's aging pipelines and poor cleanup efforts. (AP Photo/Sunday Alamba)
