| Zusammenfassung |
| Piloted by the State of Geneva and implemented by the SIG (Services Industriels de Genève),
the GEothermie2020 program aims to develop geothermal energy resources in the Greater
Geneva Basin (GGB) (Moscariello A., 2016). Since 2014, many existing data have
been examined (Rusillon et al., 2017, Clerc et al., 2016) and new ones have been
collected. Nevertheless, to date the actual IT infrastructure of the State of Geneva is
neither designed to centralize these data, nor to respond efficiently to operational
demands.
In this context, we are developing a new Information System adapted to this specific
situation (Favre et al., 2017). In order to establish a solid base line for future exploration and
exploitation of underground natural resources, the centralization of the geological
surface/subsurface knowledge is the real challenge. Finding the balance between
comprehensiveness and relevance of the data to integrate into this future complete database
system is key. Geological data are numerous, of various nature, and often very heterogeneous.
Incorporating and relating all individual data is therefore a difficult and challenging task. As a
result, a large work has to be done on the understanding and the harmonization of
the stratigraphy of the Geneva Basin, to appreciate the data and spatial geological
heterogneity.
The first step consisted in consulting all data from MSc and PhD work of the University
of Geneva (about 50) and from literature concerning the regional geology. In parallel, an
overview concerning the subsurface geological data management in Europe carried out to
learn from the experience of other geological surveys.
Heterogeneities and discrepancies of the data are the main issue. Over several years (since
late 30s) individual authors collected different type of data and made different interpretations
leading a variety of stratigraphic facies definitions, associations and environmental
reconstructions. Cross checking these data with national programs, such as HARMOS
(official Swiss stratigraphic framework; Morard, 2014, Strasser et al., 2016) is essential to
evaluate this type of harmonization system. The current work is establishing composite logs
and a stratigraphic catalog where clear stratigraphic framework for the GGB is defined. This
will provide a better understanding of the subsurface and a general framework for the new
State database.
The GEothermie 2020 Program has raised the importance of harmonizing and correlating
data in order to understand better the GGB subsurface geology. The future database will be
based on a clear and accurate geological and stratigraphic framework where relevant data will
be integrated. It will offer a valuable tool to the State of Geneva and external users to find
data easily, generate correlations, subsurface models and extract information with specific
inquiries. The development of this intelligent and interactive data management system is
pivotal to offer an easier and smart management of subsurface resources to the
State.
