In situ osmotic experiment in the Callovo-Oxfordian argillaceous formation at the Meuse/Haute-Marne URL (France): Data and analysis

This paper presents results obtained through a chemical-osmotic in situ experiment (“PEP”), carried out at the Meuse/Haute-Marne URL, aiming at interpreting pore pressure and permeability measurements in the undisturbed rock throughout the Callovo-Oxfordian argilillites. One of the objectives of this experiment was to determine the possible impact of water salinity on pore pressure, in particular due to osmotic effects.
