The evolution of reactive fluid flow depends on mineral reactivity, advection and diffusion. Reactive fluid flow through porous media has been studied using equivalent continuum models, single-flow channel or wormhole models, lattice Boltzman pore-scale models, and both network and discrete fracture network models. In particular, pore-network simulations capture pore-scale phenomena and upscale them to predict macro-scale behavior and properties. However, mineral dissolution during reactive fluid flow adds complexity to the pore-network simulation. We developed a network simulation code to investigate fluid-mineral interaction when acidified water flows through a porous network. Main focus is on saline aquifers in carbonate formations in the context of CO2 geologic storage. Please refer to "Kim, S. and Santamarina, J.C.
