AP-07: EXPERIENCE OF COOPERATION BETWEEN RAO GAZPROM (RUSSIA) AND GEOSTOCK (FRANCE) IN THE PROJECT FOR UNDERGROUND STORAGE OF NATURAL GAS IN SALT CAVERNS AT VOLGOGRAD

摘要

A new natural gas storage facility in salt is planned to meet daily and seasonal load fluctuations and providernregional security of supply of the Volgograd region. The design and field work for this new facility wasrncarried out under a cooperation agreement between RAO Gazprom, Podzemgazprom, Volgograd Transgazrnand Geostock.rnMining the cavities will be made difficult by the complex geology where the salt formation consists ofrnalternating beds of halite, anhydrite and the magnesium and potassium salts bischofite, carnalite andrnsylvinite which are more soluble and subject to high creep.rnThe results of the laboratory testing and geotechnical modelling on alternative cavern models performed byrnPodzemgazprom and Geostock are described and compared.
