TOUGH2, Version 2.0

TOUGH2, Version 2.0 is a new, enhanced version of the TOUGH2 simulation program (released in December 1999). In addition to improved versions of previously released fluid property (EOS) modules, it includes

• new modules for variably saline brines, non-condensible gases, volatile tracers, and unsaturated flow;
• coupled treatment of reservoir-wellbore flow;
• precipitation and dissolution effects, with porosity and permeability change;
• treatment of strongly heterogeneous media;
• multiphase diffusion of volatile and water-soluble tracers with parent-daughter chain decay;
• a new set of conjugate gradient solvers and preconditioners.

Numerous improvements in previously released modules have been made and new user features have been added, such as improved printed output, and writing of graphics files.

The T2VOC module for three-phase flows of water, air and a volatile organic chemical (VOC), and the T2DM module for hydrodynamic dispersion in 2-D flow systems have been integrated into the overall structure of the code and are included in the Version 2.0 package.

Data inputs are upwardly compatible with the previous version. Coding changes were generally kept to a minimum, and were only made as needed to achieve the additional functionalities desired.
