Abstract

This paper presents a semi-analytical method based on an integral formulation derived through Green's Function Method to model multi-fractured horizontal gas well (MFHWs) production performance experiencing fracture interference. The nonlinear effect of retaining pressure-dependent gas properties, namely viscosity-compressibility product, in the pseudopressure-based gas diffusivity equation is rigorously captured in the proposed method, removing previous approximations used in existing conventional production data analysis methods. The proposed method is validated against finely gridded numerical simulations models to demonstrate the capabilities of the proposed approach to forecast multi-fracture horizontal gas well performance - including early and late time periods. Fracture spacing sensivity analysis is performed to showcase the importance of a proper hydraulic fracking design to improve the well productivity.
