government regarding all
geological issues,
 employs a staff of ~ 110,
 covers an area of ~ 70,000 km2
 medium-sized GSO

3D Modelling at the Bavarian State Geological Survey:
Background and History
Bayerisches Landesamt für
Umwelt
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 für
Umwelt
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
Bayerisches Landesamt für
Umwelt
3D geological modelling at the Bavarian Geological Survey
 therefore started anew in 2004 in further holistic mapping
 using gOcad® for 2 models covering overall 7,450 km2
focused on mainly hydrogeological issues,
 faults were modelled as plane
surfaces along strike,
 again was entirely
reliant on project
staff

3D Modelling at the Bavarian State Geological Survey:
The Past and Present
Bayerisches Landesamt für
Umwelt
Increased need for green energy, in particular the exploitation
of hydrothermal energy, gave a major boost to the
3D geological modelling at the Bavarian Geological Survey

basin within the outlines

measurements (from
Pamer & Diepolder 2010)
The Upper Jurassic karstified limestone 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 Modelling at the Bavarian State Geological Survey:
The Past and Present
Bayerisches Landesamt für
Umwelt
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 für
Umwelt
Where we are now
 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"

3D Modelling at the Bavarian State Geological Survey:
Preparing for the New Challenges
Bayerisches Landesamt für
Umwelt
 Need of cooperation on different levels
 internally: spread 3D modelling among more of our staffers
 integration of field geologists into the model building
processes
 interstate & federal collaboration for exchange of information,
sharing best practice, and standardization of data and
data access
 joint cross-border 3D modelling
 trans-national projects on shared geological structures
 fostering university research and development on data
management and interoperability of 3D modelling issues

3D Modelling at the Bavarian State Geological Survey:
Preparing for the New Challenges
Bayerisches Landesamt für
Umwelt
Cooperation on different levels
 internally: spread 3D modelling among more of our staffers
 integration of field geologists into the model building
processes by standardized workflows
 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.

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

Challenges and chances of GeoMol
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)
 lack of ability to exchange 3D geoscience data efficiently
and deficiency in semantic interoperability
 network of excellence attracting universities to participate
 inclusion of university research and development

Summary
 In a medium sized GSO challenges of a complex and
continuously evolving technology such as 3D modelling
can not be solved alone.
 Cooperation on different levels helps to match up to
conceptual and technical advancements of 3D modelling.
 Cooperation on conceptual and technical issues helps to
define standardized processes and products and thus
ensures mutual benefit.

Outlook
 The Study Group 3D will continue in standardization of
processes and products, eventually leading to a common
3D data model
 Application for EU grants for GeoMol in January 2012
 implementation of the project from 2013 to 2015
 Continuation and expansion of transnational networking
for a joint 3D Molasse model even if funding application fails
 enhanced participation of the Study Group 3D in testing and
implementation of GST
