A comment from an aquaintance.

#3 Sooner or later we're going to have to start a numbering scheme for all the "what went wrong" theories going around.

#4 This as not a rare order of events, and only becomes a failure after other things fail. It is a bit of a 'short cut', but last I knew, a legal and generally accepted one. Count on that changing (horse, barn door etc.)
Minor correction to the writer: the cement is not 'poured' into the pipe: it is pumped through the drill pipe and out the end of it at the depth the base of cement is intended, where typically a 'bridge plug' (a piece of hardware) was set shortly before. The cement is then 'spotted' over perhaps a 500' long stretch of the well, then flushed out of the drill pipe, allowed to harden, and finally the heavy mud still in the hole above the new cement plug is replaced with a lighter weight fluid. Two reasons: 1) cement is TOO dense and it could exert too much pressure on the bottom of the well and cause it to split, with the cement leaking out into the rock, and leaving areas uncemented up the column, 2) it is intended to be a temporary plug, to be drilled out later when the well would be completed for production.
