Apparently Russia has already done it. 4 Times.
By burrowing a Nuclear Device near the location of the spill and detonating it, the Soviets have successfully imploded similar blowouts.
Presumably a small yield device would be used. Nothing Tsar Bomba.
What do you think? Underwater Fallout? Gulf-Wide oil spill? The lesser of 2 evils?
The other hand being that nations like Iran would hold up the scenario as a proponent to having their own 'non-aggressive' Nuclear Arsenal.

Barack Obama sends nuclear experts to tackle BP's Gulf of Mexico oil leak
The US has sent a team of nuclear physicists to help BP plug the "catastrophic" flow of oil into the Gulf of Mexico from its leaking Deepwater Horizon well, as the Obama administration becomes frustrated with the oil giant's inability to control the situation.
The five scientists visited BP's main crisis centre in Houston earlier this week, along with Mr Chu, and are to continue to work with the company's scientists and external advisers to reach an answer.
In an interview with The Daily Telegraph, Mr Hayward said the five-hour meeting involved a "very deep dive" into the situation at hand, with "lots of nuclear physicists and all sorts of people coming up with some quite good ideas actually."
Pressed further about the meeting, he said they had "come up with one good idea" but declined to elaborate.
