found as conventional traps, but they are self-generating and self-storage gas reservoirs. The natural fracturing network can particularly enhance shale tight formation permeability [4]. Shale gas capacity can be attained through microfractures in shale formation. These fractures involve both a percolation path and a storage space of shale gas. They create the necessary communication and connectivity for the shale gas to reach the wellbore. Furthermore, shale gas recovery factor can be achieved through the existence of reservoir fractures' and its density and characteristic and

Shale reservoirs are usually well stimulated and completed with good natural fractures and bedding. High brittleness is one of the significant parameters, which relates to the share failure during shale reservoir hydraulic fracturing process. It is responsible for the formation of complex fracture networks and the connections between natural fractures. Hence, the main purpose of utilizing stimulation technology on shale gas formation is to generate effective fracture networks to improve the reconstruction volume and enhance the reservoir capacity [5].
