Background The previous versions Phase 2010: The current version Phase 2011: Online Access Phase 2012: 3D Planning Tool Outlook
Agenda
SGM 2010 – Fribourg (19./20.11.2010)

Mont Terry Rock Laboratory Mechanical, hydrogeological and geochemical test
site for property investigation of the Opalinus Clay Start in 1996, operated by swisstopo Experiments carried out by partners (EU, US, JP, CA)
The role of the drill holes Most of the experiments are carried out in drill holes Every drill hole has been exactly surveyed The complete set of drill holes (~900) is accessible
through the Borehole Information System

Data acquisition & processing is purely manual Data mapping, QC, update and 3D generation
Quality control is purely manual Manual check for errors by visual control
Consequence Entire workflow is time-consuming, defective and
cost-intensive Updates on an annual basis
Borehole Information SystemPrevious versions - status up to mid-2010

Data specificationPhase 2010 - Acquisition & processing
Data acquisition Drillcore mapping Survey using cadastrial
methods ( coordinates) Drillcore metadata ( phase,
location, fluid etc.) Drillcore analysis data
Data processing Survey & metadata: Text editor Drillcore maps and fotos: HTML
page Analysis data: HTML page HTML pages: Linked in text
editor to drill core

Data storage Several text files CSV
Quality control Defined rules to check data input
- Grammar, coordinates, physical locations etc.
On-the-fly semi-automated cross-check using drop-down menus
Entire integrity check using F9-key

Driver Search engine to be a more dynamic, user-driven GUI
Queries using well know operators (e.g. AND, OR etc.) Annual update cycle should be shortened and eased
Consequences Migrate Borehole Information System to a database Distribute data in a portable environment (e.g. memory stick) Search engine gets more functionality
Organisation Principle dataset: Extranet platform of the Mont Terri project Updates by automatic importation of database dumps
Borehole Information SystemPhase 2011 – Online access

Borehole Information SystemPhase 2012 – 3D planning tool
Driver Available rock volume for new experiments is finite New drill holes must not interfere, need spatial independency
planning is paper work no entire overview possible Planning purposes: On-site localisation of collapsed boreholes Assurance at the real beginning of the experiment only
Consequences Partners plan their future drillholes in a full 3D environment Planning of new projects gets more reliable
Organisation Partners get a user account Data not visible for other partners

Borehole Information SystemSummary & outlook
Usability & functionality Front-end: Functionality increases with the user interface not
changing that much Back-end: Semi-automated data acquisition workflow for
higher data accuracy and more up-to-date data
Benefit for partners (starting 2011) More detailed search queries Planning of new experiments gets faster & very easy General update intervals get shorter online access Data update gets very fast and easy
