History of company:

    The history of underground storage in impermeable rocks dates back to March 1959, when Resolution No.84 of the Council of Ministers of the USSR on designing and construction of the first Soviet rock salt based underground storage in the area of Ishimbay city was issued. An underground storage laboratory was established in the same year at VNIIST (All-Union Research Institute for Construction and Operation of Pipelines).
    In 1962 construction of Yar-Bishkadaksk light oil product underground storage in rock salt designed for storage of operating raw materials inventory or finished products as well as for long-term storage of light oil products (petroleum, diesel fuel) began. In 1966 the project was put into service.
    In 1963 construction of the Yerevan underground natural gas storage began. Compressed air was used as nonsolvent to control the underground cavern shaping during construction of the storage.
    In 1964 the underground storage division supervised by Vasiliy A. Mazurov was integrated into the newly established VNIIPromgaz institute (All-Union Research Institute for Gas Use in the National Economy and Underground Storage).
    In 1992 Podzemgazprom Technical Research Centre headed by Vyacheslav V. Smirnov was established under the aegis of the Underground Storage Division of VNIIPromgaz.
    In 1998 Podzemgazprom Technical Research Centre was reorganized into Podzemgazprom Ltd and became a subsidiary of Gazprom JSC.
    Pavel G. Tsybulsky was appointed General Director of Podzemgazprom Ltd. in March 2006.
    Valery G. Khloptsov was appointed acting General Director of Podzemgazprom Ltd. in April 2010.
    Valery G. Khloptsov was appointed General Director of Podzemgazprom Ltd. in April 2011.
    Valery G. Khloptsov was appointed General Director of Gazprom geotechnogogy LLC in April 2011.
