Paper presented at the ISRM International Symposium - EUROCK 2016, August 29–31, 2016
Paper Number: ISRM-EUROCK-2016-147
... the requirements on the storage of natural gas in rock salt caverns have changed essentially. The operating procedure of injection and withdrawal was influenced mostly seasonal. A typical operation was characterized by a high gas inventory in the summer and therefore a high maximum internal cavern pressure...

... 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...

... & Wittlinger 1990, Segall et al. 1994). Seismicity induced by fluid withdrawal cannot be explained without taking into account the accompanying stress changes, which are associated with the larger-scale contraction of the reservoir caused by pore pressure reduction. The magnitude of the events can...

... with different withdrawal and injection rates, the second scenario includes idle time periods under maximum pres- sure. The main differences are demonstrated and discussed with respect to recommen- dations for the rock mechanical design rock salt has a time dependent material behav- ior stress redistributions...
