ABSTRACT We present a comprehensive model to simulate fracture nucleation and propagation in porous media, incorporating chemical reactions. This integrates three main processes: fluid flow reactive transport, the mechanical deformation of fractured media using variational phase‐field approach. To account for reactions, we use geochemical package PHREEQC, coupled with finite‐element transport solver (OpenGeoSys), reactions both thermodynamic equilibrium kinetically, considering changes porosity. represent damage, introduce variable that ranges from intact material fully damaged material. accounts porosity as result separate damage represented by variable. test our through various examples showcase its ability capture driven Our is implemented within open‐source finite element framework OpenGeoSys.
