Abstract
The main constrain of pore network modelling simulations is to develop a network structure which is close enough to the real structure of porous media. Although recent approaches can capture the real structure of medium, but performing sensitivity analysis is cumbersome due to the complexity of developed networks. For many years, the results of using regular based networks has not been promising but one reason for their inefficiency might be the simplicity of equations and ignorance of wetting layers. In this study, it is tried to understand can these networks be a good representation of porous media if advanced equations are used in the calculations? To achieve this aim, a simple regular cubic network is distorted by removing some of throats randomly. The describing parameters of network are tuned to match macroscopic properties of real porous media. The developed network is validated using the experimental data available for Bentheimer sandstone. This study shows that such a simple network can be adequately representative of a real rock structure if advanced equations and concepts (eg. Shape factor and wetting layers) are used in calculations. This simple network can be used for sensitivity analysis of pore-scale mechanism with acceptable results.
