Why not make relief well construction mandatory in advance of any drilling operation? Well, I'm sure that's crazy talk! Only an insane government would require the BPs of the world to drill relief wells alongside their main wells, right?
Drilling a relief well is drilling. So now you doubles the cost and double the risk of problems. BP screwed this well up as MANY have been drilled safely. Mandating that two wells be drilled at the same time would be a good way to kill deepwater drilling in the coverage area!
