The ,fluid,, which now has a slightly higher pressure than when it entered the first stage, enters the next impeller and diffuser stage to repeat the process. The ,fluid, passes through all stages of the pump, incrementally gaining pressure in each stage until it achieves a total developed head, or designated discharge pressure, and has sufficient energy to travel to the surface of the well.

That means if modeling the, fracturing-fluid flowback, without considering the proppant transport and induced hydraulic fractures, the load recovery will be overestimated by 0.37%. This small proportion is because the proppant production under a, low fluid flowback rate, is very less and stops in 3 h.

Usually, a good shale gas reservoir has a lower flowback rate, which is contrary to a tight gas reservoir. Based on relevant research, the clay swelling-induced cracks and fracturing fluid diffusion account for the special phenomenon in the shale gas reservoir [27,42]. Induced cracks increase the space for both liquid retention and gas flow.
