水力压裂面临着几个环境挑战：该过程是高度水密集型的，产生大量的废水，并且与联产天然气的广泛燃烧有关。同时缓解这些挑战的一个可能的解决方案是使用来自燃烧天然气的能量进行现场废水处理，从而减少燃烧气体、废水量和后续页岩生产所需的淡水量，因为处理后的废水可以再利用。本研究建立了一个分析框架，了解这种方法的可行性。我们得出结论，从完井后的前10天开始处理废水所需的热能为148000-865000 MJ（140-820 MMBTU），并将产生750-6800 m3的处理水。此外，使用2012年德克萨斯州燃烧天然气的体积，可以产生的处理水的理论最大体积计算为1.8 - 5.4亿m3，约占3%-9%。
Hydraulic fracturing faces several environmental challenges: the process is highly water-intensive, generates significant volumes of wastewater, and is associated with widespread flaring of coproduced natural gas. One possible solution to simultaneously mitigate these challenges is to use energy from flared natural gas for on-site wastewater treatment, thereby reducing flared gas, volumes of wastewater, and volumes of freshwater necessary for subsequent shale production as treated wastewater could be reused. This study builds an analytical framework for understanding the feasibility of this approach. We concluded that the thermal energy required to treat wastewater from the first 10 days after well completion is 148000–865000 MJ (140–820 MMBTU) and would generate 750–6800 m3 of treated water. Additionally, using the volume of flared natural gas in Texas in 2012, the theoretical maximal volume of treated water that could be generated was calculated to be 180–540 million m3, representing approximately 3–9% ...
