Short summary
In the context of geological repositories for radioactive waste, hydraulic packer testing has been performed in deep boreholes located at the edge of the Northern Alpine Molasse Basin. Our presentation will give an overview on methodologies and workflows with emphasis on the numerical design and analysis techniques applied to the hydraulic packer tests. The applied methodology provided high-quality results and reliable estimates of the hydraulic conductivities in the low-permeability rocks.
