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 siting regions Jura Ost, Nördlich Lägern and Zürich Nordost.
The Bachs-1-1 exploratory borehole is the ninth (and last) borehole drilled within the framework of this project. The drill site is located in the western part of the Nördlich Lägern siting region.
Dossier I:
In this report, first results from the Bachs-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 Bachs-1-1 borehole are presented, in particular the photo documentation of the cuttings and core samples.
Dossier III:
In this report, first results from the Bachs-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 Bachs-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 Bachs-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 Bachs-1-1 borehole are presented, in particular from petrophysical wireline logging.
Dossier VII:
In this report, first results from the Bachs-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 Bachs-1-1 borehole are presented, in particular the data from laboratory analyses on core material for porewater characterisation.
Dossier X:
In this report, first results from the Bachs-1-1 borehole are presented, in particular from the stochastic petrophysical log analysis combining selected wireline measurements.
Summary Plot:
In this report, the results from the Bachs-1-1 borehole are summarised in the form of a composite plot, including a short technical explanation of the information displayed.
