A parametric study was also conducted to understand the impact of natural fractures on the optimum design conditions. Different natural fracture intensities (i.e., spacing) were investigated...

.... A cased-hole completion is applied to the MFHW, and hence, the fluids flow into the wellbore through hydraulic fractures only. Gravity effects are ignored due to the single-phase flow condition and the extremely tight texture of shale rocks. The MFHW can produce under either a constant-rate condition...
