The ,flow-back fluids, at the only shale ,gas, well to be fracked in the UK to date (Preese Hall Well 1, Lancashire, [SD 37532 36627]) were even more saline, with a TDS (estimated from specific electrical conductance measurements reported by Broderick et al. Reference Broderick, Anderson, Wood, Gilbert, Sharmina, Footitt, Glynn and Nicholls 2011) of 86.9–97.9 g/L.

After a fracturing treatment on a gas well, the pumping pressure is relieved and fracturing fluid, mixed with water from the rock formation, begins to flow back through the well casing to the wellhead. In treatment-and-reuse scenarios, this is the water that will serve as the basis for fracturing fluid for the next job.
