Fracturing fluid trapped in the micro-nano induced cracks is difficult to flowback due to the strong capillary force, but under the capillary force, the liquid can move from induced cracks to small pores, which can greatly increase the main gas flow channel, and thus after well shut-in for a time, shale gas can flow out of the formation.

During a hydraulic ,fracturing, treatment, water-based ,fracturing, fluids are generally injected at high pressure and high ,rate,. In practice, only a small portion of the ,fluid, is returned to the surface as ,flowback,. Part of this ,fracturing fluid, can invade the rock, which results in a lower permeability to hydrocarbon near fracture face, also known as a water block.
