  •  I didn't say you conflated the two (2+ / 0-)

    But you've included a statement from an ill-informed source that attempts to do so.

    •  not to belabor the point, but... (8+ / 0-)

      to say that drilling and fracking are not related is silly.  you have to create a horizontal bore before you can frack.  while you can drill without fracking, you can't frack without drilling.  fracking is not a stand-alone technology - drilling is inextricably intertwined with the process of fracking.  if you are describing the technology of fracking, it cannot be described faithfully without including drilling technology.

      anyway, that's how i see it.  thanks for your input.

      •  You need to understand the situation better (0+ / 0-)

        Hydrofracturing is relatively rare, compared to the number of wells and boreholes that are drilled.  It's wrong and misguided to demonize drilling by itself.

        Of course you need a hole before you can hydrofracture.  And, despite your assertion, hydrofracturing does not need a horizontal well.  It can (and is) done in vertical wells.

        And hydrofracturing is done for more than gas recovery.  It's also done to open fractures in formations with low hydraulic conductivity so in situ treatment of contaminated groundwater can be done more effectively.

        My advice is to focus on the hydrofracturing; not the drilling. The most risky elements in hydrofracturing, in my opinion, are:

        (1) The geologic setting in which it occurs; specifically, the natural protection (if any) afforded by the stratigraphy in the area being fractured.

        (2) The quality of the well seal and any mechanical integrity testing completed to confirm an effective and adequate seal exists.

        (3) The storage (generally in ponds) and ultimate disposal of brines and hydrofracturing liquids. They are a major potential source of contamination to underground sources of drinking water.

        •  Can those surface ponds affect water wells (0+ / 0-)

          750' deep, like some of the wells in Wyoming? Wouldn't the ponds more likely contaminate the ground water rather than the aquifer?
