TOUGHREACT is a numerical simulation program for chemically reactive non-isothermal flows of multiphase fluids in porous and fractured media. The program was developed by introducing reactive chemistry into the multiphase flow code TOUGH2 V2. Interactions between mineral and fluids can occur under local equilibrium or kinetic rates. Multiple gas species can be transported and undergo equilibrium gas-water reactions. Porosity, permeability, and capillary pressure changes can be coupled to mineral precipitation and dissolution reactions.

A comprehensive user’s guide is available, including worked sample problems addressing geothermal reservoirs and hydrothermal systems, nuclear waste isolation, groundwater quality, sequestration of carbon dioxide in saline aquifers, and supergene copper enrichment.


We will assume that participants have some familiarity and experience with multiphase flow in general and TOUGH2 in particular, as well as numerical modeling experience for batch geochemistry in geologic media. People interested in TOUGHREACT who do not have prior TOUGH2 experience are strongly urged to register for Part 1 as well.

Material to be Distributed during the Course

Course attendees will be provided with the necessary course materials, including handouts of presentations and a User’s Manual.  Participants are required to bring their own laptop; needed simulation software and input files will be provided. Note that a separate TOUGHREACT software license is required if  TOUGHREACT will be used after the training course at the participants’ home institution. Such a license can be obtained from the Berkeley Lab Software Center.
