Initially, the oil or gas is allowed to flow from the well along with the majority of frac fluid, referred to as flowback fluid. 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 …
