In the process of hydraulic fracturing, fracturing fluid invades the formation and reacts with shale. Water-sensitive clay minerals swell when exposed to water. This results in a change in the mechanical properties of shale. However, the influences of a long-term water–shale reaction on mechanical properties are still unclear, and an …

Predicting the production rate and estimating the ultimate recovery are of great significance for the optimization of shale gas development. One possible reason for production decline is the width reduction of propped fractures caused by proppant deformation, embedment, crushing, and viscoelasticity of the reservoir.
