Book excerpt: Shale gas has become one of the most rapidly developing natural gas, providing approximately half of the natural gas for the U.S. Together with the development of shale gas exploration, large quantity of flowback and produced water is being produced. Management of flowback and produced water has become one of the most challenging issues for shale gas operators. Traditional disposal of flowback and produced water is challenged by the increased freshwater demand, water shortage, and more restraining regulations. Beneficial reuse of flowback and produced water is becoming a more attractive option, as it reduces freshwater demand for hydraulic fracturing, minimizes disposal costs, and helps to meet regulations. This study aimed to develop a decision-support tool for shale gas produced water management, treatment and beneficial use. Water quality and quantity data were retrieved from national produced water database and industrial database. Treatment technologies were critically reviewed about their capacities to treat shale gas flowback and produced water. A case study was conducted to evaluate shale gas flowback and produced water beneficial use potentials in Tioga County and Washington County in Marcellus Shale, Pennsylvania. The results showed that the costs of produced water treatment and beneficial use decreased significantly as the treated water flow rate increased. Produced water reuse is more cost-efficient than deep well injection when flowback and produced water from a cluster of wells collected together, and treated in a satellite facility. Small operators are recommended to cooperate to treat and reuse shale gas wastewater together to be more cost-effective. In addition to monetary benefits, reuse of flowback and produced water also augments water resources, reduces the industry reliance on local water supplies, decreases the risks of wastewater spill, remits traffic load and road wearing, helps to meet regulations and policies, and reduces public concerns.
