The flowback fluid is separated from the natural gas or oil and stored at the wellsite. The well can flow (or produce) for years, but the flowback of fluid only occurs over days or months. The carefully recovered flowback fluid is either reused for another well or disposed in government-approved facilities. Operators must track flowback fluid volumes and report them to regulators. Frac Fluid. The choice of frac fluid is …
