N2 - This thesis addresses the challenge of upscaling in porous media, a critical issue where the accurate prediction of continuum behavior depends on pore-scale characteristics. By employing statistical modelling, the study thoroughly investigates the upscaling footprint from pore to Darcy scale for homogeneous pore network models. Through detailed property scaling, comprehensive REV relationships that quantify the impact of microscale size and connectivity heterogeneities on continuum behavior are developed. Model-agnostic analysis concurrently reveals complex non-linear dependencies between pore-scale features and emergent flow behavior. These insights highlight the intricate nature of upscaling and underscore the necessity for precise microscale characterization to inform effective macroscopic predictions.
