Once the hydraulic fracturing is completed, fluid returns to the surface in a process known as “flowback”. The US Environmental Protection Agency (EPA) estimates that fluids recovered range from 15–80% of the volume injected, depending on the site conditions.

The ,fluid, temperature in fractures is expected to be relatively low during early ,flowback, for the shale gas wells without extended shut-in days. Among such shale gas wells, fracture cleanup driven by gas vaporizing water might thus be negligible due to the relatively low temperature.
