Abstract Flow simulation through fractured media using the DFN approach has computational constraints. Fracture continuum approach is much more computationally saving runtime and memory utilizing mapping discrete fractures onto finite-difference grid. In this study, a two-dimensional DFN model is solved in presence of wells in steady and transient conditions. The DFN solutions are used as reference for verification. A proposed technique is utilized for mapping the discrete fractures onto fine or coarse resolutions in steady and transient conditions. The DFN and the grid-based models are solved in a stochastic framework. A grid-conductivity correction is presented to preserve the total flow of the original DFN in steady and transient conditions. Furthermore, a grid-porosity estimation is proposed to addresses the correct pressure transient response of the grid-based models. Drawdowns are assessed and a technique is proposed to minimize the errors of grid maximum drawdown |
