A total of about a hundred of underground reservoirs for liquid and gaseous hydrocarbon storage have been built and operated based on technologies developed by LLC «Gazprom geotechnology».
The major projects constructed in rock salt in Russia and CIS countries include a number of storages for oil products (petroleum, diesel fuel, gas condensate), natural and liquefied gas (propane, butane, propylene, butylene) in the Republic of Bashkortostan, the Irkutsk Region, the Republic of Belarus, in Ukraine and Armenia.
The two-level underground storage of liquefied hydrocarbon gas (propane, butane) built in Armenia, as well as the helium concentrate storage in Orenburg region are unique facilities unparalleled in the world practice.
The projects of LLC «Gazprom geotechnology» are:
The storage for gas condensate at the Orenburg Helium Refinery;
The storage for unstable gas condensate at Orenburg gas condensate field;
The pilot plant equipment for gas field treatment at Orenburg gas condensate field;
The underground reservoirs for blowing of gas condensate wells at Astrakhan gas condensate field;
