TBO Bülach-1-1: Data Report

To provide input for site selection and the safety case for deep geological repositories for radioactive waste, Nagra has drilled a series of deep boreholes in Northern Switzerland. The aim of the drilling campaign is to characterise the deep underground of the three remaining siting regions.   Summary Plot: In this report, the results from the Bülach-1-1 borehole are summarised in the form of a composite plot, including a short technical explanation of the information displayed.   Dossier I: In this report, first results from the Bülach-1-1 borehole are presented, in particular from the drilling operations and including the drill site construction.   Dossier II: In this report, first results from the Bülach-1-1 borehole are presented, in particular the photo documentation of the cuttings and core samples as well as the resinated core slabs.   Dossier III: In this report, first results from the Bülach-1-1 borehole are presented, in particular a detailed description of all encountered lithologies and lithostratigraphic units.   Dossier IV: In this report, first results from the Bülach-1-1 borehole are presented, in particular the data from detailed microfacies analyses as well as ammonite- and palynostratigraphy, complementing the lithostratigraphic report (Dossier III).   Dossier V: In this report, first results from the Bülach-1-1 borehole are presented, in particular from the detailed core goniometry and the characterisation of the tectonic structures observed in the drill cores.   Dossier VI: In this report, first results from the Bülach-1-1 borehole are presented, in particular from the wireline measurements(petrophysical logging and microhydraulic fracturing).   Dossier VII: In this report, first results from the Bülach-1-1 borehole are presented, in particular from the hydrogeological investigations such as hydraulic packer testing.   Dossier VIII: In this report, first results from the Bülach-1-1 borehole are presented, in particular the data from detailed laboratory analyses on core material for petrophysical and geochemical rock and porewater characterisation.   Dossier IX: In this report, first results from the Bülach-1-1 borehole are presented, in particular from geomechanical laboratory testing on core material, such as triaxial and oedometric testing.   Dossier X: In this report, first results from the Bülach-1-1 borehole are presented, in particular from the stochastic petrophysical log analysis combining selected wireline and Multi-Sensor Core Logger as well as laboratory measurements.
