He is now head of the Republicans Governors Associations, he takes that up next week. What I do respect about him is he stayed with his state first

But as for the control explosion, it has been used in the oil industry in the past but in a different sense. Whenever they would have an oil gusher
than caught flame they would use an explosion to blow it out. That same pressure that would blow out a flame could do a down pressure on the crack and
seal it. And if you think about it, if that explosion was to suck in all the air, it wouldn't necessarily ignite the methane
That would be a good question for happykat to answer if that would be plausible.
When an oil well fire is put out with explosives pressure, as such, has nothing to do with it. What actually happens is that the explosion consumes
all the oxygen around the well fire and starves it. The explosion is also set off several yards above the well head. The fire fighters then make sure
that they flood the well head with water so the heated metal doesn't re-ignite the flame. A very good movie to see that covers this subject quite
well is "Hell Fighters" starring John Wayne. It is the true story of Red Adair who pioneered the explosive snuffing of oil well fires. Finally, as
to pressure, there is no real pressure placed on the well since the explosion takes place several yards above it and not in it.
The proposal to seal off the B P Macondo well with a nuke was not a totally new idea. It just hadn't been done in a well a mile down under the water.
Where it had been done is in Siberia when the Russians tapped into a deep well with too much pressure to handle. That well was being drilled in the
Siberian Tundra. They shoved a nuke right down the wells throat and the black glass chamber it created sealed the well off.
With the B P Macondo well they couldn't shove a nuke straight down the casing since the drilling platform was no longer there, having been destroyed
in the initial fire and explosion. Plus, the well itself along with the blow out prevention valve were too damaged even if the platform were still in
place. The plan, if they were to do it at all was to drill two new shafts off to the side of the Macondo well and come in at an angle to meet the
original well at great depth. They proposed to use the upper of the two relief wells to tap directly into the original well with better equipment that
could handle the pressure and to force heavy drilling mud and cement into the original well so that as it rose up the casing the weight of it would
stop the flow. They had little success with that and the second, and lower, relief well was supposed to be drilled close to the original well but not
break into it. Then they would send a nuke down to create the same kind of black glass seal that stopped the Russian well.
However, they finally managed to cut the old blow out prevention valve off and install a new well head control and that finally stopped the blow out.
It has since come out that the original well casing was far too damaged and oil and methane have continued to infuse into the sea bed from the damaged
areas of the well. That is why an area of about 25 miles radius around the well is bulging and still leaking oil and methane. And, that is also why
there is still concern about a possible eruption of that 25 mile radius area of the sea bed if too much pressure builds up and weakens the rock
The idea of using a bomb of any kind on the salt dome is a totally different animal. First of all, the whole area around the salt dome is
destabilizing and fracturing. Secondly, nothing about the salt dome is anywhere near as deep as the 5 mile depth, plus a mile under the water, of the
Macondo well. That means that any bomb they use is going to have to be a very shallow explosion compared to the one used in the Russian well and
proposed for the Macondo well. My personal opinion as an engineer, but not a geologist, is that such a bomb would be a disastrous mistake and could
accelerate the failure of the entire salt dome system.
