Measurement of physico-chemical parameters in deep clay formations : Development of a methodology for sampling and testing
Knowledge of deep formations for the disposal of radioactive waste requires in situ measurements or laboratory measurements on samples of the site material. In the case of clay massifs, the taking and sampling of cores is particularly difficult. A methodology which allows the suppression or reduction of the factors perturbing these operations is needed. The most suitable materials and techniques were selected from a study of clay coring and conservation methods. These were used for a series of core samples taken at Mol in Belgium. Subsequently, permeability measurements were carried out in the laboratory on samples from vertical drilling and were compared with in situ measurements. The latter were taken by horizontal drillings from the gallery of the underground facility HADES at Mol. There is good overall agreement between the results of both types of measurements.
