I just noticed that Cuadrilla Resources have some interesting notes on 'returned water' on their website, suggesting to me that E2 may be closer to 'typical' than many appear to have thought.

Fracturing fluid together with water that may be stored underground in the shale rock return up the bore with the gas and this is known as “returned water”. Typically about 40% of the fracturing fluid used during the fracturing process flows back to the surface in returned water within the first few weeks of well flow. .
Much of the fracturing fluid returns to the surface over the producing lifetime of the well.
