Lake Tuz Natural Gas Storage salt formation covers an area of . It is long and around thick. It has a salt dome structure. To create the caverns in the salt formation, fresh water was brought by pipeline from Hirfanlı Dam at distance. Using the process of solution mining, water was injected through a borehole into the salt formation, and the saline water, which is formed after dissolution of salt in water, was pumped back to the surface leaving a void in the formation. The salt water was transported to far away Lake Tuz by pipeline. Gas pressure inside the storage is nearly . The
