Part of the Nagra's deep borehole project (TBO project) is the assessment of the barrier properties of the formation Opalinus Clay and its confining geological units. The subject of this tender is performance of fluid logging tests in these TBO boreholes, including their analysis and documentation. The work comprises the provision of complete fluid logging testing equipment with multiple borehole geophysical probes, winches and accessory equipment, and the running of multiple logs in vertical and inclined boreholes, under pumping or non-pumping conditions. The work has to be completed with the interpretation of results and their documentation.
