Abstract
Summary
This paper reports on the first modeling of sandstone matrix acidization using a comprehensive geochemical simulator based on the partial local equilibrium assumption. This new model allows any combination of kinetic and equilibrium reactions involving any number of chemical species, which greatly increases the simulator's predictive abilities compared to existing sandstone acidizing models. The new simulator, KGEOFLOW, which is applicable to a variety of reactive transport processes in petroleum reservoirs, is used to predict optimal acid injection rates based on the amount of mineral dissolution and precipitation.
