ABSTRACT
As the earth climate changes many methods are pro-
posed to mitigate the emission of CO
to the atmos-
phere. On one side CO
is injected into underground
for only sequestration or to enhance oil/gas recovery
(EOR/EGR). On the other side renewable energy
sources like an Enhanced Geothermal System (EGS)
is put to use. In all these applications coupled
THMC geo-processes play a significant role. Up to
now a number of computer codes have been devel-
oped to simulate these processes. One of the most
important codes is TOUGH-FLAC developed by
LBNL. Details of this code are found in Rutqvist et
al. (2002), Rutqvist & Tsang (2003). This paper
presents integration of TOUGHREACT and
FLAC3D based on TOUGH-FLAC with additional
implementation of new THMC coupling concept.
Firstly we present our concept, validate the code
with one example using the code TOUGH-FLAC
from the literature and then the new code is applied
to analysis of THMC coupled behaviour of a saline
aquifer in North German Basin subjected to CO
