Design study for a macropermeability test in an argillaceous formation (Boom clay)
In the present report a test design has been developed for determining the in situ permeability of the Boom clay on a large scale at the Mol site. Since a URF is operational in the Boom clay at the Mol site the test has been designed to be run in or from this facility. The proposal is an in-situ macropermeability test with a set-up comprising a central borehole (metric scale in length) designed to allow various types of control of the water-level, surrounded by a lattice of piezometers installed in the clay mass for the monitoring of the interstitial water pressure changes as a function of the various water-level controls. The report describes the potential set-ups and the theoretical background on the basis of existing literature and experiments. The method (technical and practical data of a test set-up) is also described and documented. The method proposed is based on years of expertise gained within the field of in situ migration and hydrogeologic investigations in the Hades-URF.
