Produced water is the largest volume of waste product generated during oil and natural gas exploration and production. The traditional method to dispose of produced water involves deep well injection, but this option is becoming more challenging due to high operational cost, limited disposal capacity, and more stringent regulations. Meanwhile, large volumes of freshwater are used for hydraulic ...

Produced water and ,flowback, water In recent years, there has been a revolution in shale gas and shale oil production using hydraulic ,fracturing,. This revolution has made the U.S. the largest producer for both natural gas and crude oil. For both shale oil and gas production, a significant amount of water is used for hydraulic ,fracturing, operations.
