Lake Tuz Natural Gas Storage Lake Tuz Natural Gas Storage Lake Tuz Natural Gas Storage () is an underground natural gas storage facility under construction in Aksaray Province, central Turkey. It was developed artificially in a salt formation. The storage facility is situated near Sultanhanı town in Aksaray Province south of LakeTuz at a depth of . It was established by creating salt caverns. The twelve man-made salt caverns with a total volume of can hold natural gas. Daily delivery from the storage can be up to when needed. The geological structure of the area is suitable for large underground natural gas storage facilities. The
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
