This is sometimes called “flowback water” to distinguish it from the naturally occurring produced water that is extracted from the rock formation. 2 In some cases, a large proportion of the extracted water is flowback, while in others it can be little or none.

Because hydraulic fracturing operations do not use water after a well is fractured, opportunities to recycle fracturing fluid (flowback water) within the well are limited, so make-up water accounts for most of the water used. However, flowback water can be reused to fracture a different well, thereby contributing to the make-up water used in the hydraulic fracturing operation.

Handling Produced Water From Hydraulic Fracturing

Produced water and fracture flowback was trucked away and disposed into injection wells or collected in evaporation ponds. Operators later began using in-field recycling with clean produced water for fracturing with some success; however, this required significant resources to stage the water at sufficient rates for the 24-hour field operations.
