Maybe a bigger picture going on here. BP, Transocean and others are all in the crosshairs of the government for this incident. According to the congressional testimony report the well was sealed and the cement and casing catastrophically failed. Reasons unknown by the public now. Possibly, the stack is sitting on a damaged casing and if closed may not hold the pressure anyway. So the best option may be to drill the other well to relieve pressure on this one so it can be properly capped. But that takes time. 30 days or so. All the while oil is migrating toward the coast and we all have heard the doomsday environmental predictions. The politicians and media wants immediate action and will accuse the oil companies of negligence if they don’t do something. So the junk plug suggestion may just be buying time while they get the relief well bored.
