Petropedia - What is Flowback? - Definition from Petropedia

Flowback is a water-based solution that flows back to the earth's surface after completing the hydraulic fracturing of a shale gas reserve. This water-based solution consists of chemical additives, mud, clay, dissolved metal ions and TDS (total dissolved solids). The water becomes murky because of the abundance of suspended particles.

Hydraulic fracturing in the United States - Wikipedia

Hydraulic fracturing in the United States, began in 1949. According to the Department of Energy (DOE), by 2013 at least two million oil and gas wells in the US had been hydraulically fractured, and that of new wells being drilled, up to 95% are hydraulically fractured.The output from these wells makes up 43% of the oil production and 67% of the natural gas production in the United States.

Characterization of hydraulic fracturing flowback and produced water (HF-FPW) is an important initial step in efforts to determine a suitable treatment method for this type of wastewater. In the present study, fracturing flowback and produced water samples were obtained from well CN-F and well CN-E in the prophase and anaphase stages of the Changning shale gas mining area.

Appendix F: Glossary | Flowback and Produced Waters ...

Flowback water: After the hydraulic fracture procedure is completed, the injected fluid is allowed to flow back into the well, leaving the proppant in the newly created fractures. As a result, a portion of the injected water returns to the surface and this water is called flowback water, which initially may mix with the naturally occurring produced water from the formation ( Veil, 2015 ).
