The hydraulic fracturing operation is highly complex in fractured reservoirs. The fundamental key to a successful
operation is processing and analysis of the propagation of hydraulic fracturing in a natural fracture network. In
this paper, the hydraulic fracturing process is evaluated in a fractured reservoir in southwest Iran. The developing process of induced fracture in a natural fracture network is analysed by the Distinct Element Method
(DEM). After determining the fluid flow regime in the natural fractures of the reservoir, hydraulic fracturing is
applied along different lengths of the reservoir and in each range, the production rate is checked. Fluid flow in
natural fractures after the hydraulic fracturing operation is shown and evaluated in order to evaluate the induced
fracture effectiveness in enhancing fluid flow regimes in the reservoir. The reverse suction phenomenon which
causes changes in the fluid flow pattern in fractures and will thus affect the production rate is also studied in this
paper. Fracture coalescence will cause the induction of natural fractures to hydraulically fracture without their
intersection; this is one of the significant parameters in hydraulic fracturing in naturally fractured reservoirs
which is also discussed in detail. This paper can present valuable information on fluid flow analysis before and
after applying hydraulic fracturing in a fractured reservoir and solve some essential ambiguities in this area.
