📊 Multiscale Pore Network Model in Geoslicer

15 Jul , 2025 Digital rock physics,GeoSlicer,Pore Network Model

📢 We’re excited to share our multiscale pore network module, available in Geoslicer, our open-source digital rocks platform at LTrace.
These new developments enable pore-scale one- and two-phase flow simulations on porous media images containing both resolved and unresolved porosity.

Our approach builds on the concepts introduced by Bultreys (2015) and Xu (2021), which describe macro- and microporous domains as separate network elements. We extend this by using a bundle of capillaries model to represent subscale porosity, calibrated using experimental data or scenario-testing assumptions for the subresolution pore size distribution.

🧠 Key features of the new module include:
✅Simulation of absolute permeability, relative permeability, drainage/imbibition cycles, and Buckley-Leverett-based production prediction
✅Ability to handle networks with millions of pores in absolute permeability simulations, and over a hundred thousand in relative permeability simulations, depending on available hardware
