There is a difference between right and wrong. If a well demolition done with an explosive method looks anything different that what these videos show below, it was done wrong. Plain and simple. That is a pretty bold statement you may think, and you are right.
I will explain what I mean.
Explosives work on the basic principal of point of least resistance. If your sealing material comes flying out of the well, then evacuation to the surface was the point of least resistance. That means that you did not achieve casing perforation.
