Short summary
Pore network models accurately represent porous media by constructing networks from experimental pore space characterizations, enabling simulation of reactive transport processes like adsorption and dissolution.

Key points
- Pore network model realism depends on the correspondence between the constructed network and the actual pore space.
- Experimental techniques like direct imaging, mercury intrusion porosimetry, and gas adsorption are key for pore space characterization.
- Network construction methods are adapted to data from experimentally characterized pore systems.
- Applications include simulating reactive transport, with focus on adsorption, dissolution, precipitation, and biomass growth effects on transport coefficients.

Abstract
Pore network models have been applied widely for simulating a variety of different physical and chemical processes, including phase exchange, non-Newtonian displacement, non-Darcy flow, reactive transport and thermodynamically consistent oil layers. The realism of such modelling, i.e. the credibility of their predictions, depends to a large extent on the quality of the correspondence between the pore space of a given medium and the pore network constructed as its representation. The main experimental techniques for pore space characterisation, including direct imaging, mercury intrusion porosimetry and gas adsorption, are firstly summarised. A review of the main pore network construction techniques is then presented. Particular focus is given on how such constructions are adapted to the data from experimentally characterised pore systems. Current applications of pore network models are considered, with special emphasis on the effects of adsorption, dissolution and precipitation, as well as biomass growth, on transport coefficients. Pore network models are found to be a valuable tool for understanding and predicting meso-scale phenomena, linking single pore processes, where other techniques are more accurate, and the homogenised continuum porous media, used by engineering community.
