Production of natural gas from shale formations presents key water management challenges. As the number of gas drilling operations continues to grow in shale plays around the world, and the practice of hydraulic fracturing (frac or fracing) of gas wells remains widespread, efficient water use strategies are becoming critical aspects of shale gas operations. Fresh water supplies for drilling and fracturing...
