Considering an abundance of sandy aquifers with fresh water in the formation, we believe that because of the salt diffusion, the formation water salinity in clayey sequences must be low in the vicinity of aquifers, and much larger in the middle of the sequences. Because the swelling pressure increases with decrease of the pore water salinity, clay with fresh water can be of high porosity.
