The company tracks changes in water chemistry over time by collecting flowback water samples every 500–1,000 bbl of post-fracturing flowback. Kroff uses the sequential flowback analyses to recommend strategies for compatible flowback water reuse, including plans for water remediation, blending fresh water and optimizing the design of fracturing fluids.

The Institute of Directors forecasts a UK shale industry developing, between now and 2030, 100 pads with 40 multilateral wells each, with each pad using 0.5 million cubic metres of water[5]. Assuming that 50% of this ,fracturing fluid, flows back, a total of 27 million cubic metres of ,flowback, will need to be disposed of during this period.
