The evaluation of mass and heat transport in the subsurface is a complex task that cannot usually be solved with purely analytical approaches. Numerical modeling is an important tool for simulating, analyzing and understanding underground processes. The physical processes are described by mathematical systems of equations, which with the natural conditions are abstracted, but all relevant parameters and interactions are
mapped.
As a service provider, we offer all aspects of modeling and numerical simulation. From consulting and data compilation through modeling and parameterization to calculation and visualization, we provide everything from a single source and thus ensure consistent and fast processing. We have extensive experience in modeling on various size and time scales and are aware of the sensitivity of model parameterization. The determination of statistically proven and representative input data has top priority for us, whereby we can fall back on many years of experience in the analysis of geoscientific data sets.
Our range of services in the field of numerical
simulation includes:
-
Problem
analysis and demonstration of cost-effective solutions
-
Construction
of 2D and 3D structural models according to available underground
data
-
Conversion
of the structural models into numerical grid models
-
Data
analysis for parameterization of the model units and definition of
the boundary
conditions
-
Numerical
simulations for thermal and hydraulic processes including the
mutual conditions
-
Performance
of probabilistic analyses – scenario considerations
-
Visualization
of results, analysis and evaluation
We work with our in-house
simulation tool SHEMAT or SHEMAT-Suite, which incorporates the basic
code for the calculation of heat and fluid transports in porous media.
The flexible program environment offers us to program additional
modules for a various questions on the subject of "heat".
This range from model-in-model tools for simulating geothermal probes
and other heat exchangers, to the simulation of freezing processes,
the implementation of multi-phase systems for high enthalpy geothermal
fields to a “fracture generator tool” for the analysis of
fractured media. Our projects are mainly in the field of geothermal
energy, but we also deal with other issues where heat emissions and
heat transport play a role, such as the embedding of power cables, the
storage of nuclear waste or enhanced oil recovery.
