Numerical Study of Simultaneous Multiple Fracture Propagation in Changning Shale Gas Field

Figure 1. Three transverse fractures with a uniform spacing of 23.3 m in a single stage.

Numerical Study of Simultaneous Multiple Fracture Propagation in Changning Shale Gas Field A series of case studies were investigated to analyze the effects of engineering parameters on simultaneous multiple fracture propagation. The fracture spacing, perforating number, injection rate, fluid viscosity and number of fractures within one stage were considered. The simulation
