“…As already mentioned, other factors linked to the nature of rock and fluid help the production in shale gas reservoirs. Literature highlights the slip and adsorption effects of the gas (Li et al, 2016;Jiang & Younis, 2015). In the case of slipping, the gas that is in direct contact with the solid surface can slip on the surface.…”

Typically, hydrocarbon reservoirs have heterogeneities that influence pressure variation in producing wells. In the case of natural fractures, the layer model has been widely applied to obtain analytical and numerical solutions. In this model, we superimpose the porous media layers representing the porous matrix and fractures. In this work, the layer model is used in the numerical simulation, using cylindrical geometry and finite differences, to determine the pressure in natural gas producing wells. We consider shale gas reservoirs, and obtain the numerical results investigating the effects resulting from the presence of fractures and non-Darcy flow due to slip and adsorption phenomena. This work studies grid refinement and performs numerical verification, as well as a sensitivity analysis varying the main physical parameters that directly influence the reservoir and well pressures, such as permeability, porosity, and thickness of the fracture, reservoir temperature, and the Langmuir pressure and volume. As expected, from specialized and diagnostic plots, we can visualize how fractures favor the flow while capturing typical flow regimes of fractured reservoirs described in the literature.

“…To describe network fractures, discrete fracture models have been widely used to simplify the complex fracture network, including pre-existing natural fractures and hydraulic fractures. 8,9 Jiang et al 10,11 developed a novel hybrid fracture model (UDFM-MINC) that effectively integrates the discrete fracture-matrix model (DFM) for simulating the SRV of shale formations. The discrete fractures model (DFM) can better solve the noncoupling problem of gas flow between matrix and fractures.…”

“…To overcome this limitation, scholars try to study the gas flow through numerical simulation. With the consideration of multi-scale flow mechanisms and ad-desorption, Jiang (2015) used dual permeability model to characterize the production dynamic in shale [34]. The results show that the desorption gas is an important production supplements in low pressure period.…”

This paper presents two representative models to analyze the flow dynamic of multi-scale porous medium in hydraulic fractured horizontal shale gas wells. In this work, considering the characteristic mechanisms (multi-scale porous space, desorption and diffusion), flow equations in shale are established. After that, two representative models (discrete fracture model and dual-porosity model) are tailored to our issues. Solved by the control-volume finite element method (CVFEM), influences of fracture network system on productivity in shale reservoirs are analyzed in detail. Based on the analysis, the effects can be summarized as follow: at the beginning of production, high conductivity fracture network means more free gas could be produced; at the later part of production, high conductive fracture network can form a large low pressure region, which can not only stimulate the desorption of adsorbed gas, but also reduce the flow resistance to the well. Finally, the sensitivities of characteristic parameters in shale are discussed.
