Interactive Visualization for Prognosis and Risk Assessment of Geothermal Reservoirs
I. Tedjo-Palczynski, T. Kuhlen
This visualization project is part of the BMBF funded joint research project MeProRisk
(novel MEthods for exploration, development, and exploitation of geothermal reservoirs – a
toolbox for PROgnosis and RISK assessment). The goal of the visualization is to help
detecting geothermal deposits, improving the underlying geological model, and finding
coherencies between the geological properties, e.g. between permeable zones and
temperatures.
Due to scattered and limited source of geological measurements the generation of reliable
geothermal datasets is a current topic in the geothermal research. Thus, it is crucial to
investigate the possibilities to include and emphasize the estimated uncertainty of the data in
the visualization.
Displaying the visualization in an immersive environment provides not only a better visual
depiction of the volume dataset than the currently widely-used desktop visualization
applications, but also enable the use of 3D user interfaces to support the analysis of the
complex geological structures. To facilitate the assessment of data uncertainty based on the
results of measurements and numerical simulations, we developed an exploratory multiview
visualization. Furthermore, to support the geophysical parameter study, we work on direct
manipulation user interfaces for optimal experimental design in collaboration with the
Institute for Scientific Computing.
