... ABSTRACT: The performance of seal systems in rock salt formations can be dominated by the increased permeability of the damaged rock adjacent to an excavation. Under favorable stress conditions, this damaged region is expected to and return to a condition comparable to intact rock salt...

..., and the effect of the value of in-situ stress, the rheological characteristics of the muddy shale and rock salt formations, as well as the elastic and geometric parameters of well casing and cement mantle are also studied. The results would have a great value for the design of well casing in creep formations...

... ABSTRACT ABSTRACT: A permeability model is developed from triaxial flow test data to predict the permeability increase of rock salt around storage caverns, as affected by excavation, confining and internal pressures, age and shape. The confining and internal pressures may increase...
