Abstract
Seasonal gas storage in rock salt caverns is a proven technology since several decades. However during the last years new operation modes with high pressure rates are aimed at. The corresponding loading of the rock salt mass differs because the change of gas temperatures during operation and the consequences of these temperature changes on the stressing of the salt rock mass must be taken into account. Within the rock mechanical design a loading history, i.e. a robust pressure versus time dependency, has to be defined which covers the possible withdrawal and injection scenarios. Alternatively the gas flow from or into the individual caverns can be taken as basic requirement. In each case, the thermodynamic influence should be considered in addition to the influence of creep. The paper discusses possible load cases which are defined pressure controlled or volume controlled respectively. It shows the differences of the time dependent state variable as well as the stress regime with respect to the assessment of the safety and economic operation.
