尽管水力压裂的水强度，最近的生命周期分析得出结论，如果增加的天然气产量用于天然气联合循环发电厂，将发电从燃煤蒸汽循环发电厂转移，增加页岩气开发将导致水消耗的净减少。这项工作扩大了这些研究，估计在德克萨斯州河流流域的快速页岩气开发和发电使用期间，从2008年8月至2009年12月的消耗性用水的变化的空间和时间模式。虽然德克萨斯州的用水量总体上有所下降，但一些河流流域的用水量增加，另一些流域的用水量减少，这取决于流域内开采活动的程度，该流域使用冷却水的发电厂的组合以及电力部门基于价格的变化。由于天然气开发对用水影响的时空异质性，
Despite the water intensity of hydraulic fracturing, recent life cycle analyses have concluded that increased shale gas development will lead to net decreases in water consumption if the increased natural gas production is used at natural gas combined cycle power plants, shifting electricity generation away from coal-fired steam cycle power plants. This work expands on these studies by estimating the spatial and temporal patterns of changes in consumptive water use in Texas river basins during a period of rapid shale gas development and use in electricity generation from August 2008 through December 2009. While water consumption decreased in Texas overall, some river basins saw increased water consumption and others saw decreased water consumption, depending on the extent of extraction activity in the basin, the mix of power plants using cooling water in that basin, and price-based changes in the power sector. Due to the temporal and spatial heterogeneity in the consumptive water impacts of natural gas de...
