TBO Bözberg-2-1: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.
The Bözberg-2-1 exploratory borehole is the fourth borehole drilled within the framework of this project. The drill site is located in the southern part of the Jura Ost siting region.
Dossier I:
In this report, first results from the Bözberg-2-1 borehole are presented, in particular from the drilling operations and including the drill site construction.
Dossier II:
In this report, first results from the Bözberg-2-1 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 Bözberg-2-1 borehole are presented, in particular a detailed description of all encountered lithologies and lithostratigraphic units.
Dossier IV:
In this report, first results from the Bözberg-2-1 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 Bözberg-2-1 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 Bözberg-2-1 borehole are presented, in particular from the wireline measurements (wireline logging, micro-hydraulic fracturing and pressure-meter testing).
Dossier VII:
In this report, first results from the Bözberg-2-1 borehole are presented, in particular from the hydrogeological investigations such as hydraulic packer testing.
Dossier VIII:
In this report, first results from the Bözberg-2-1 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 Bözberg-2-1 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 Bözberg-2-1 borehole are presented, in particular from the stochastic petrophysical log analysis combining selected wireline and Multi-Sensor Core Logger as well as laboratory measurements.
Summary Plot:
In this report, the results from the Bözberg-2-1 borehole are summarised in the form of a composite plot, including a short technical explanation of the information displayed.
