Anyone that has flown in the Delta knows you can follow the slicks up any creek to the wooden bunker boat or rusty steel barge. Add in the locals tapping into the pipelines, terrorists blowing up pipelines....then added to the poor maintenance by Shell Nigeria.....then you can get a real perspective on the problem. It is Shell in the end...as they operate under those conditions...in a country riddled by corruption and greed including government officials, politicians, village chiefs, and Shell Management themselves.
