Abstarct: Accelerated growing up of energy consumption in the world has been made
humanities to be more dependent to energy sources. The consumption of natural gas as one
of the most important energy sources has been grew up rapidly in last decade. Regarding
gas consumption in Iran and so for other countries, limitation existence in natural gas
production to consumption chain has been faced up such countries to energy shortage
especially in cold months of the year. The main purpose of gas storage is to overcome this
problem.
Nowadays, underground natural gas storage especially in salt formations (for its many
advantages) has been used more and more in recent years. Existence of huge and favorite
salt formations in Iran has been prepared good situation to use this underground storage
method.
Consideration stability of salt cavern, the integrity of this underground space which used
for gas storage purpose is vital. Various parameters such as cavern geometry and geologic
parameters, operation conditions and geomechanic properties of surrounding rock of cavern
has effect on behavior of this underground space. The purpose of this study is investigation
of the manner of these parameters on stability of salt cavern under various situations by
using LOCAS software. LOCAS is finite element software specially dedicated to salt
caverns. The results of this study show that cavern depth, minimum and maximum
operation pressures and creep properties of salt rock respectively are most important
parameters which are effect on stability of salt caverns.
