Geo-scientific database for research and development purposes

Document available in extended abstract form only. The Research and Development Division must manage, secure and reliable manner, a large number of data from scientific disciplines and diverse means of acquisition (observations, measurements, experiments, etc.). This management is particularly important for the Underground research Laboratory, the source of many recording continuous measurements. Thus, from its conception, Andra has implemented two management tools of scientific information, the 'Acquisition System and Data Management' [SAGD] and GEO database with its associated applications. Beyond its own needs, Andra wants to share its achievements with the scientific community, and it therefore provides the data stored in its databases or samples of rock or water when they are available. Acquisition and Data Management (SAGD) This system manages data from sensors installed at several sites. Some sites are on the surface (piezometric, atmospheric and environmental stations), the other are in the Underground Research Laboratory. This system also incorporates data from experiments in which Andra participates in Mont Terri Laboratory in Switzerland. S.A.G.D fulfils these objectives by: - Make available in real time on a single system, with scientists from Andra but also different partners or providers who need it, all experimental data from measurement points - Displaying the recorded data on temporal windows and specific time step, - Allowing remote control of the experimentations, - Ensuring the traceability of all recorded information, - Ensuring data storage in a data base. S.A.G.D has been deployed in the first experimental drift at -445 m in November 2004. It was subsequently extended to the underground Mont Terri laboratory in Switzerland in 2005, to the entire surface logging network of the Meuse / Haute-Marne Center in 2008 and to the environmental network in 2011. All information is acquired, stored and manage by a software called Geoscope. This software, fruit of a continuous computer development over the past ten years, can store several hundreds of million data. The GEO database (geo-scientific database) is a tool developed by Andra since 1992, in order to group in a secured computer form all data related to the acquisition of in situ and laboratory measurements made on solid and fluid samples as well as observations related to environment. This database has three main functions: - Acquisition and management of data and computer files related to geological, geomechanical, hydrogeological and geochemical measurements on solid and fluid samples and in situ measurements (logging, on sample measurements, geological logs, etc.) as well as observations on fauna and flora. - Available consultation by the staff on Andra's intranet network for selective viewing of data linked to a borehole, a sample or a watch point and for making computations and graphs on sets of laboratory measurements related to a sample. - Physical management of fluid and solid samples stored in a 'core library' in order to localize a sample, follow-up its movement out of the 'core library' to an organization, and carry out regular inventories. Three geo-scientific software are linked to the Geo database: - Geosciences portal: it's a web Intranet application accessible from the ANDRA network. This application is used for the acquisition of hydrogeological and geochemical data collected on the field and on fluid samples, observations related to environmental monitoring, as well as data related to scientific work carried out at surface level or in drifts. - GESTECH application is a software used to integrate geomechanical and geological data collected on solid samples in the GEO database. - INTEGRAT application is a software application automatically integrates data files in the GEO database. For the sake of traceability and efficiency, references of the fluid and solid samples, of the containers (crates, cells, etc.) and storage zones of the 'core library', are managed by a bar-code system and an optical reader. At the present, the GEO database groups information under: - 1 518 indexed works. - 44 750 solid samples. - 13 063 fluid samples. - Environmental data will start be integrated from this year The GEO database also contains 32 664 photographs related to the samples and structures as well as 15 341 in situ measurement files (geological logs, logging, etc.)
