A Novel Radial-Composite Model of Pressure Transient Analysis for Multistage Fracturing Horizontal Wells with Stimulated Reservoir Volume

Figure 5

Analysis of influential factors for the multistage fractured horizontal well in the three-region reservoir: (a) influence of fracture conductivity on the typical curves; (b) influence of fracture spacing on the typical curves; (c) influence of the dimensionless radius ratio of the middle region to the inner region on the typical curves; (d) influence of the dimensionless radius ratio of the outer region to the middle region on the typical curves; (e) influence of the permeability ratio of the inner region to the middle region on the typical curves; (f) influence of the permeability ratio of the inner region to the outer region on the typical curves; (g) influence of the storage ratio of the inner region to the middle region on the typical curves; (h) influence of the storage ratio of the inner region to the outer region on the typical curves.
