I’ve wondered at times whether or not these horizontal wells would be re-fracked at some point in the future.  Looks like they will be.  At least, the companies are thinking up ways to do it.  This one involves pumping “diverting agents” into the old cracks at high speeds.  Subsequent fracking would open up new cracks.  Pretty doggone cool.

I bet there are other ways to re-frack, too.  Shoot, it seems to me that you should be able to pump some kind of cement that would dry to be as hard or harder than the rock formation into the horizontal part of the drill bore, let it harden, and drill a completely new horizontal in a slightly different place.  You could use the old vertical part of the well, so you don’t have the expense of a new pad and vertical portion of the well.  That’s just one thought off the top of my head.  It’s a freebie for any gas company that wants to use it.  You’re welcome, guys.
