The effect of small deviatoric stresses on cavern creep behavior

Résumé

One-year-long creep tests performed under very small deviatoric stresses and a 6-month-long brine outflow test performed in a shallow salt cavern are described. Both strongly suggest that the rate of salt creep under small deviatoric stresses is likely to be much faster than what usually is inferred from laboratory tests performed under higher mechanical loadings. Numerical computations prove that cavern-closure prediction has potential significant consequences.
