.... A sensitivity analysis was considered to study the effect of the formation capillary pressure and reservoir pressure on the fluid flowback and fluid loss due to counter-current capillary imbibition. The study results showed that the fluid saturation in the near fracture face shale matrix is highly reduced...

... Fig. 1 is a schematic diagram of a hydraulically fractured horizontal well where the fractures are perpendicular to the wellbore. Between successive fractures are low-permeability reservoir matrices. We assumed that the fracture face is at a constant pressure that is equal to the bottom-hole...

... to prevent these effects can lead to fracture-face softening and sloughing, resulting in significant loss of fracture conductivity. The use of chemical additives designed to minimize the effect of water-based fluids on clay minerals is a well-established technology for formation-matrix treatment of high...
