3D Modelling at the Bavarian State Geological Survey Examples for Cooperation Towards 3D Standards


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

medium-sized GSO


3D Modelling at the Bavarian State Geological Survey: Background and History


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


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


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

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

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

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


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"

Where we are now


3D Modelling at the Bavarian State Geological Survey: Preparing for the New Challenges


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

Need of 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

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







Geological 3D models stored and maintained at the German State Geological Surveys as of 07/2011:

The 'Study Group 3D'of the Information Systems Steering Group of Geological Surveys in Germany

Of 16 State Geological Surveys 11 are actively 3D modelling + federal agencies BGR, LIAG 2 have assigned 3D model-

ling to local universities

foundation of a state / federal working group on 3D geological modelling in 2005'Kommunikationsforum 3D'




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

The Molasse basin features a multitude of resources and subsurface potentials

Competition for the use of subsurface space is reaching a critical level, not only in shallow urban areas, but also in the deep subsurface

northern limit of hydrocarbon traps

adequate depths for CCS

Bavarian border

gasfield

oilfield

license area for hydrothermal energy

mostly exploited, now partly used for gas storage

(from Diepolder & Schulz 2011)




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.

Area of projected 3D model of the entire peri-alpine Molasse basin and underlying units (~ 60,000 km2 ~ 45 % in Bavaria - 1100 km SW-NEup to 140 km N-S) and data available in the Bavarian part ↓↓




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

Milestones of GST development


Developments of the TU Mining Academy Freiberg: The Role of German GSOs in Development of GST


determination of specific needs and technical demands,

coordinated by the Study Group 3D supply of 'real' 3D geological models for implementation

in different test beds joint specification of a geo-data model for 3D models

based on GeoSciML and BoreholeML (and INSPIRE) commissions for customization of individual data bases integration of the GST developer team into GeoMol as a

'full' project partner

The role of German GSOs in development of GST


3D Modelling at the Bavarian State Geological Survey: Examples for Cooperation Towards 3D Standards


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.

Summary




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
