KivSimEiBase vs.
KivSimEi* (free beta version)
Export and import capabilities
for the TOUGH2 suite of simulators
* The enhanced import/export functionalities of KivSimEi are developed in the framework of the GEOTREF research project (www.geotref.org). They are freely available through a beta version of KivSimEi, which is a temporary plugin. Eventually, they will be moved into a new plugin GefSim, which will provide a comprehensive link between SKUA-GOCAD and geothermal simulators.

KivSimEiBase vs. KivSimEi 4
Export of grid data
Basic grid data to export
• Rocks model complexity
• Block data (volume, permeability factor)
New in KivSimEi: export of top and
bottom boundary condition (BC) cells
• Possibility to add top and bottom cells
(not present in the reservoir grid known
by SKUA-GOCAD), and to specify their
connections with top and bottom
reservoir grid cells, in order to define
top and bottom Dirichlet boundary
conditions (BC) in TOUGH2 (prescribed
state variable values)

KivSimEiBase vs. KivSimEi 6
• New in KivSimEi
Taking into account discontinuities
Conductive discontinuity=> increased transmissibility
through increased area
Sealed discontinuity=> decreased transmissibilityNot a heat transport barrier
Adding intermediate cells known only by TOUGH2

KivSimEiBase vs. KivSimEi 7
Taking into account discontinuities
• Nonconductive discontinuities
New in KivSimEi: non-
conductive discontinuities
• Accounting for nonconductive
discontinuities by adding
intermediate cells, known only
by TOUGH2, in between
GOCAD-SKUA grid cells.
• New cell properties are
calculated from GOCAD-SKUA
grid cell properties, based on a
permeability (reduction) factor
and a volume (reduction)
factor.

KivSimEiBase vs. KivSimEi 8
Taking into account discontinuities
• Conductive discontinuities
New in KivSimEi: conductive discontinuity modifiers
• Accounting for conductive discontinuities by correcting the transmissibility of connected cells for which the interface is intersected by one or several discontinuity surfaces.
• The correction applies to the interface area (only interface parameter available as input to TOUGH2) and is based on the intersection length and the transmissivity assigned to each discontinuity.
• Exporting conductive discontinuities into a dual permeability model is an option which is not yet available (interest to be confirmed).
