The cam at this moment is on BOP and appears to be gushing more than ever, like top (that you never see) has been eroded away by cavitation at riser...be interesting to see what collection rates are like in weeks ahead... assuming we can believe what they say.
If the relief wells cannot 'bottom kill' this well, these relief wells (and likely few more) are still the answer. You sink say 6 wells each pulling in oil/gas surronding the leaking well and then pull as hard as those wells can. The idea is to pull all the oil/gas away from the leaking well in the center to the contained wells around it. This is similar to what is frequently done at sights were ground water pollution is found. Pull hard to direct the flow to a contained or treatment well, treat the contaminated water pulled up and then either reinject to the ground water or safely dispose of it to surface water.
I don't know if the 'right' number of wells is 2, 3, 4, 6 or whatever. But it can be done. Also it might not 100% stop the leak, but could/would DRASTICALLY reduce it. Might even reduce it enough to then succeed with a subsequent top kill.
There is also still the potential for an explosive (conventional, I don't believe nuclear is necessary) collapse of this well in conjunction with relif wells.
At this point, no solution is good as good went weeks ago. Now the answer is the best amoung lesser choices. But the ultimate doom and gloom, end of the world hyperbole is still extremely remote even if possible.
