An Analytical Flow Model for Heterogeneous Multi-Fractured Systems in Shale Gas Reservoirs

Figure 1. Schematic of physical models for hydraulically fractured horizontal wells. (a) The typical five-region flow model proposed by Stalgorova and Mattar [10]. (b) The improved five-region flow model (new model). Fracture half-length: xf; width of the hydraulic fracture: wD; distance from the hydraulic fracture to stimulated reservoir volume (SRV): y1; no flow bound: x2,y2.

An Analytical Flow Model for Heterogeneous Multi-Fractured Systems in Shale Gas Reservoirs Tang et al. [4] established a three-dimensional numerical model based on the construction of spatial discretization by the finite volume method. Wang [5] proposed a unified model for shale gas reservoirs based on discrete fracture networks to investigate shale
