NEMBE, Nigeria - When Lambert Ogbari learned that the oil giant Shell was selling its local operations to a Nigerian firm, he said he felt hopeful his living conditions would finally improve. But he quickly noticed that maintenance on the oil wells surrounding his village had declined.
Then, one night, Ogbari woke up to a loud bang, followed by the smell of gas. Crude oil was shooting out of a well near his home with such force that people hundreds of yards away could hear the roar.
