After ,fracturing,, the internal pressure of the shale or other formation forces the injected fraccing ,fluid, to the surface where it is stored in tanks or pits prior to disposal or recycling. These recovered fluids are referred to as “,flowback,.” Disposal options for ,flowback, include discharge into surface water or underground injection.

29/1/2015, · “Produced water” is a byproduct of oil and natural gas drilling. “,Flowback,” water is the ,fluid, pushed out of a well during fracking. Apache is recycling both types, which are typically trucked away and put into underground disposal wells. Some drillers frack without water entirely. And some drillers have stopped using water entirely.
