Their margins are still pretty low and someones going to get careless and when that happens, the environmental impact is very severe. The whole shale industry could collapse and the immediate supply vacuum could see USD100-150 oil again. Usually in most cost cutting exercises, the first reductions will be in margins of safety eg the latest episode with Boeing.
