Fracturing (at least in oil and/or gas wells) is not done with explosives.
Worked in the oil biz too. Smile | :) That is new to me. I was taught that perforation is done by perforation guns, which in turn, use explosives. Wiki seems to agree.[^]. Not to mention the good old nuclear times. I wonder what would environmentalists of 2017 say about that?

Fracturing doesn't make oil and gas flow; it makes the existing flow better (it increases the permeability of the rock, it doesn't create permeability from nothing).
Indeed. And hydraulic fracturing does more of the same. For example, the sand that they pump also goes into the fractures keeping them opened for an extended period.

Economically speaking, hydraulic fracturing enables non-profitable wells to become profitable. That is why the world oil reserves have increased. We knew oil was there all the time -- but it was just not profitable to exploit it before.

An improperly done frac job will fracture upwards from the producing zone instead of into the producing zone. The "burning water" problem is usually from an improperly done frac job, not so much from a poor cement job (but it could be either).
It is good to mention that deepest drinking water is only a few hundred ft deep down. And your average well can be 10.000 ft. So sometimes it is quite impossible for the two to "meet" without gas traveling through the well to the depth where it can leak into water that comes to the surface. But it depends. Definitely shallow wells are more dangerous to the environment.
