It will work to. I emailed the company the day after they found the leak. Nitrogen does not have to expand. At that depth and pressure it would become a solid. It would give them long enough to cement the well. Methane hydrates would form and double plug the well.
I think if we should just let the thing run until it runs out of oil. Then we can just go out to the Gulf and collect the oil there at the shore, filter it, refine it and just let nature run its course.
To he*ll with the beaches and the sealife. Who cares about that?
