Interesting...and certainly contradicts what I have previously read. But I don’t think anyone is claiming the tight rock is magically made more porous than sandstone by fracking. Rather, the physical act of effectively breaking the rock in two, and not allowing the pieces to come back together, due to the fracking sand, creates large gaps between pieces of rock. And the theory is these propped open gaps will behave differently than porous rock.
Time will tell...maybe. It may not even get to the point where wells are shut down.
Who knows.
But putting that aside, don’t fracked wells have a much steeper decline on the production curve? That alone makes a fracked well a much shorter play, and easier to react to price changes than a conventional well.
