Tigress Simulation provides a wide range of analysis techniques
for black oil, compositional and EOR simulation including thermal
modelling, with gas condensate and dual porosity options. Both
IMPES and fully implicit time stepping methods are supported for
1D, 2D and 3D models.
A unique strength is the use of the integrated project database
as the focal point for the compilation and management of the
sequence of models required in a simulation study. No keyword files
are necessary as all data is stored in the database.
The architecture of the Tigress Simulation module facilitates
the use of third party simulators. Tigress Ltd has experience in
working both with exploration and production companies to
link in-house simulators and in the use of other industry standard
products such as Eclipse, Chears, SURE and Falcon MPP
simulator.
