Paper presented at the ISRM International Symposium - EUROCK 2020, June 14–19, 2020
Paper Number: ISRM-EUROCK-2020-058
... Abstract The global demand onto large volumes of hydrocarbons to be stored in rock caverns lead to the development of very large caverns. The larger the cavern sections, the larger the potentially unstable blocks and the risk of megawedges. The hydrodynamic containment of hydrocarbons in...

... ABSTRACT: Since several years, the demand for the storage of gas in rock salt caverns has changed from seasonal to high cycling operation. The new operation mode requires relatively fast pressure change rates in the cavern which in turn leads to temperature changes in the gas. The consequences...
