- •
Permeability of bedded salt rocks ranges between 10−17 m2 and 10−21 m2 by lab-testing.
- •
The interface did not dilate and show uprush of κ under high deviatoric stress.
- •
Pure rock salt shows the lowest permeability and plastic behaviours when compressed.
- •
Natural gas has a small seepage distance around the cavern in bedded salt rocks.
- •
Tightness of the gas cavern in such bedded salt rocks is satisfactory for storage.
