This causes the invaded hydraulic-,fracturing fluid, to be trapped in small pores within the matrix and accumulate near the hydraulic fracture. The profile of liquid saturation in the figure shows the overall blockage caused by both aqueous and condensate phases that leads to a significant reduction in the gas relative permeability near the fracture (Fig. 1b).
