3D MODELLING AT THE BAVARIAN STATE GEOLOGICAL SURVEY – EXAMPLES FOR COOPERATION
3D Modelling at the Bavarian State Geological Survey Examples for Cooperation Towards 3D Standards
Bayerisches Landesamt fürUmwelt
Federal organisation of Germany16 independent GSOs + 2 federal institutes (BGR, LIAG)
The Bavarian Geological Survey
is part of the Environment Agency (LfU), is neutral advisor to the state government regarding all geological issues, employs a staff of ~ 110, covers an area of ~ 70,000 km2
3D Modelling at the Bavarian State Geological Survey: Background and History
Bayerisches Landesamt fürUmwelt
The Bavarian Geological Survey
for more than 150 years produced geological maps and cross-sections, thus flat-ironing the 3-dimensional concepts in the mind of the geologists. Since 1995 map production is fully digital and GIS based, but still a 2- or 2.5-dimensional issue neglecting a lot of structures and architectures of geology. Prior to improvements in visualization hardware in the 1990's it was almost impossible to capture the geologist’s visions, concepts and understanding of underlying geological processes.
3D Modelling at the Bavarian State Geological Survey: The Beginning
Bayerisches Landesamt fürUmwelt
3D geological modelling at the Bavarian Geological Survey
started in a holistic mapping project covering 2,850 km2
used GeoObjects 2 for modelling 24 geological units down to the crystalline basement disregarded faulting was carried out from 2000 to 2002 by project staff … which we lost after the end of the project, thus loosing all our 3D modelling experience !!
3D Modelling at the Bavarian State Geological Survey: The Past and Present
Bayerisches Landesamt fürUmwelt
Increased need for green energy, in particular the exploitation of hydrothermal energy, gave a major boost to the3D geological modelling at the Bavarian Geological Survey
Volume grid of the UpperJurassic aquifer underneath the Molasse basin within the outlines of Bavaria, gridded with the temperature field derived from borehole measurements (from Pamer & Diepolder 2010)
The Upper Jurassic karstified lime-stone aquifer of the Alpine foreland basin (Molasse basin), reaching down to > 5000 m, is the most important and exploitable heat reservoir in central Europe

3D geological modelling of the Bavarian Molasse Basin
interpretation of scanned seismic cross-sections (overall about 12,000 km) and about 3,000 km2 of 3-D seimics, using a regionalized velocity model improved with each new borehole evidence, started with a 3,000 km2 large area around Munich, where density of existing plants is highest and further investors are at the ready will keep us busy the next years

3D Modelling at the Bavarian State Geological Survey: Current Situation
Bayerisches Landesamt fürUmwelt
models released up to now cover about 20 % of Bavaria, extent and resolution are comparable to 100K scale maps, are steadily improved, extended and interconnected. 3D modelling is carried out by 3.5 people, of which only one is in a permanent position.
impossible to meet the challenges of the future: The subsurface issues of the "energy turnaround"

Cooperation on different levels
Geology is inherently 3D. 3D models emerge from the imagination in the heads of geoscientists when working in an area. This implicit knowledge has to be made explicit and thus available to the organisation and the public. Crucial when suffering a permanent staff turnover due to fixed-term contracts.

3D Modelling at the Bavarian State Geological Survey: Interstate & Federal Collaboration
Bayerisches Landesamt fürUmwelt
is the communication platform for all 3D modelling activities of the GSOs in Germany stirs and coordinates commissions for R&D services and the exchange of proprietary developments in line with the 'Kiel Agreement' works on the semantic harmonization of technical terms, the standardization of model descriptions and data access for geological 3D models regularly meets twice per year and documents its activities in www.infogeo.de brings people together for networking and fosters collaboration by organizing workshops

Possible vertically zoned subsurface registry in the Molasse basin
Licensing "from soil to hell" is obsolete – 3D models are required to govern the multi-purpose use of the subsurface by vertical zoning of subsurface rights

Geology and the resources and risks connected with it do not respect political boundaries. Thus we have to work trans-nationally.

11 project partners (GSOs, universities and planning authorities) from 5 countries + external experts manifold experience in seismic interpretation, basin evaluation and modelling vast diversity in organizational structure, responsibilities and data management (hard-/software, formats, legal restrictions)
