I'm wondering how clean does the water need to be to reuse as frac water, flowback from one frac will or should be used for the next frac...
From what I understand the Shale gas is dry, so the water from a producing well would be flowback, but I guess to longer it stays downhole the dirtier it gets...
Like I said earlier, the amount of water being used fracing is mind blowing and obviously unsustainable without recycling water.
I wouldn't think it would be that difficult to filter the water to reuse for fracing ?
