Résumé

Different ways of coupling are used to handle the mathematical and numerical dif culties of multiphase multicomponent ow and transport coupled with geochemistry. In absence of analytical solutions for such complex systems, the benchmarking of reactive multiphase simulators is essential for veri cation and validation of existing methods. This paper presents a reactive transport benchmarking exercise which aims at speci cally targeting the numerical capacity of the codes in the context of liquid and gas ow, multicomponent liquid and gas transport, gas solubility, and gas–water–rock interaction. The exercise is based on a description of the long term evolution of the sour gas reservoir. The set of benchmark cases was established to study geochemical, thermo- and hydrodynamical mechanisms; the numerical results of two cases are demonstrated.
