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.
