Analytical model for pressure and rate analysis of multi-fractured horizontal wells in tight gas reservoirs

Fig. 5 Transient pressure type curves of MFHW in tight gas reservoir

Fractal porosity and permeability were employed to describe the heterogeneous distribution of the complex fracture network. The stress sensitivity of fractures was also considered in the model. Pedrosa substitution and perturbation method were applied to eliminate the nonlinearity of the model. Analytical solutions in the Laplace domain were obtained using
