It may take a lot of explosives to do it right but I think it should work.

I wish it were that simple. From what I'm reading this well is gushing at pressures seldom, if ever, seen before. And any explosives may further fracture the underlying sea floor and open up more fissures through which the NG and oil can penetrate.

All if it adds up to the fact that this is a "super-giant" hydrocarbon deposit and it could spew for years, if not decades, polluting every body of water "downstream" from it's source.

What I'm wondering is whether they can design something similar to an arterial "stint" that can be slid down that shaft against the pressure, and then expanded to seal the bore hole below the fractured well casing. The well casing is 21" wide, as I understand it, so sliding down a 12" pipe with a magnetic plug device that expands to 21" could seem feasible.

But I'm just "brainstorming".. I don't think any such device currently exists.

What does seem obvious to me is that it's quite possible that this well may prove very difficult to cap, if not impossible. Each day the pressure is expanding the fractured boreshaft, creating a cavity far under the sea floor, that is expanding fissures and cracks and leaking oil out of the actual seafloor.
