Impact of Large-Scale Porosity Variability on Hydrogen Transport in Porous Reservoirs

The representation of reservoir heterogeneity is a key source of uncertainty in the numerical modelling of underground hydrogen storage. Most studies assume either spatially uniform porosity or small-scale random variability, whereas large-scale porosity trends commonly encounter...

LIB4RT: Automated generation of reactive-transport formulations from PHREEQC databases for implementation in multiphysics platforms

Reactive transport simulations in multiphysics platforms require accurate geochemical reaction and transport flux terms derived from thermodynamic databases and equilibrium speciation calculations. In practice, building these definitions manually from databases is time-consuming,...
