Simulation of coupled hydro-mechanical-chemical phenomena in hydraulically fractured gas shale during fracturing-fluid flowback

Fracturing-fluid flowback in hydraulically fractured gas shale is a complicated transport behavior involving hydrodynamic (H), mechanical (M) and chemical (C) processes. Although, many flowback models have been published, none of the models flly coupled the transient fluid flow modeling with chemical-potential equilibrium and fracture closure phenomena.
