Paper presented at the 53rd U.S. Rock Mechanics/Geomechanics Symposium, June 23–26, 2019
Paper Number: ARMA-2019-0124
... ABSTRACT: During the last decades the importance as well as the number of gas storage caverns in rock salt to store natural gas, compressed air or hydrogen have increased. Especially during the last years, research on the storage of compressed air and hydrogen gained importance in order...

Paper Number: ARMA-2019-1975
... ABSTRACT: During the long-term operation phase of storage caverns there occur convergence-induced additional stresses within the construction of a cavern well (casing, annulus cementation), especially in the lower part of the well. These additional stresses may lead to a local loss of well...

Paper Number: ARMA-2014-7418
... Abstract A study to evaluate the impact of operational pressure cycles on the long-term stability of underground hydrocarbon storage caverns in Singapore was performed. As the stored products are withdrawn for consumption and subsequently replenished during operations, frequent storage...

Paper presented at the 47th U.S. Rock Mechanics/Geomechanics Symposium, June 23–26, 2013
Paper Number: ARMA-2013-561
.... The viscoplastic behavior was incorporated into a numerical model to evaluate the suitability of a mined storage cavern. The numerical modeling indicated that creep will allow redistribution of stress over time. This redistribution of stress results in an increase in factors of safety against plastic failure...

Paper presented at the 44th U.S. Rock Mechanics Symposium and 5th U.S.-Canada Rock Mechanics Symposium, June 27–30, 2010
Paper Number: ARMA-10-144
... cavern is essentially a geotechnical problem. In this paper, we describe the application of the Geotechnical Safety Program (GSP) to a gas storage cavern in salt, focusing on the first two components - performance criteria and design assessment. To develop the performance criteria, we considered...

... and composite rock samples implied that the steady-state creep ratio of interlayer was one order lower than that of the salt rock. The creep deformation of surrounding rocks of storage cavern will be controlled by the salt rock layer, while the anhydrite layers will restrict the longterm volume shrinkage...

... such caverns. Casing failures associated with caverns in bedded salt domes have been documented, but less so for caverns in fairly homogeneous domal salt. We review the design and operation of gas storage caverns in domal salt. We then examine the factors that can generate tensile strains and stresses...

Paper presented at the Alaska Rocks 2005, The 40th U.S. Symposium on Rock Mechanics (USRMS), June 25–29, 2005
Paper Number: ARMA-05-734
... ABSTRACT: Finite element simulations of generic natural gas storage caverns in a bedded salt formation were used to evaluate the effect of cavern design parameters on the minimum allowable gas pressure necessary to maintain cavern stability. For these simulations, the state of stress...

... by step, from large depths. At the end of the nineteenth Century small mine caverns started to be used in Sweden as storage for compressed air, at which the air was kept under pressure by water from a higher situated water storage cavern [see Fig. No. 1). When there was a surplus of compressor capacity...
