Flexibility of underground storages in rock salt deposits consists in the possibility of storing gas, oil and condensate as well as their derivatives therein.
Underground natural gas storages are used to adjust irregular gas consumption, first of all to serve peak loads under conditions of considerable and extreme temperature drops.
Importance is attributed to creation of underground storages in rock salt for the purpose of raw gas condensate collection, preparation of gas for transportation, burial of industrial waste, field treatment of oil and gas, gas well blowing.
In addition to hydrocarbon collection and storage, underground storages are assumed to be used for technological purposes: inertia-gravity separation of gas condensate mixtures and watercut liquid hydrocarbons, i.e. field treatment of raw materials produced for preparation their of to separate transportation.
