TL;DR: In this article, the fracture properties and failure mechanisms of inclined bedded rock salt have been revealed, and the authors demonstrated that the inclined interlayer influences the deformation and fracture properties of rock salt.

TL;DR: In this article, the authors show that the permeability of nonsaline cap rock and interlayers is in the range of 10−18−10−20 m2, whereas the interface in between salt and interlayer behaves as if impervious.

TL;DR: In this article, a series of triaxial discontinuous cyclic compression tests were conducted on salt and the residual stress was reproduced through numerical simulations, showing that the interval effect decreases with the increase of the confining pressure.

TL;DR: The major risks associated with hydrocarbon storage caverns in bedded salt rock are defined and a comprehensive evaluation methodology for major risk loss is generated based on the analytic hierarchy process.

TL;DR: In this paper, a 3D geomechanical model was established based on the sonar data of the two caverns with respect to the features of the target formation, and new criteria for evaluating gas penetration failure and gas seepage were proposed.
