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

Figure 1

Schematic of the multistage fractured horizontal well in the three-region heterogeneous reservoir, where the inner region is the volume fracturing stimulation region of the multistage fractured horizontal well, the middle region is the skin damage region, and the outer region is the nonstimulated and undamaged region.
