New! The TOUGH2 User's Guide, Version 2.0, is now available
for free downloading as a pdf-file. (Report LBNL-43134,
2.2 Megabytes)
A new fluid property module "ECO2N"
for TOUGH2 is available, which is designed for studies of CO2 storage in
saline aquifers. Click here
to download the user's guide in pdf-format (Report LBNL-57952; 416 kilobytes). ECO2N is available
from the Energy Science and Technology Software Center (ESTSC) at no
additional charge to licensees of TOUGH2. Click here

TOUGH2 is a
general-purpose numerical simulation program for multi-phase fluid and
heat flow in porous and fractured media. It belongs to the MULKOM family
of codes, developed in the Earth Sciences
Division of Lawrence Berkeley National Laboratory for applications
in geothermal reservoir engineering, nuclear waste disposal,
unsaturated zone hydrology, and geologic storage of CO2 (carbon sequestration).
The source code for TOUGH2, written
in standard FORTRAN77, is available from the Energy
Science and Technology Software Center (ESTSC) of the U.S.
Department of Energy. The LBNL group, headed by Karsten
Pruess, serves as custodians of the code, and provides limited technical
support. A TOUGH2 version specifically designed for environmental
applications involving volatile organic chemicals, called T2VOC,
is also available.
With the release of Version 2.0 of TOUGH2
in December 1999, T2VOC has been integrated with the remainder of
TOUGH2 into a single program package for "forward" modeling.
A program called iTOUGH2
(inverse TOUGH2) provides inverse modeling capabilities for TOUGH2
(automatic model calibration and history matching, error analysis).
