Abstract

The study of geological systems requires the solution of complex geochemical relations. We present an implementation of a chemical solver which can handle various types of models, including surface chemistry. The implementation is done in view of easy coupling with flow simulations to obtain a fully-coupled, fully-implicit solver for chemical reaction transport equations applicable to realistic reservoir models.
