A hydrocarbon fluid storage system is described which consists of in operable conjunction: a cavern formed within an underground salt strata below a ground surface, the cavern comprises a lower liquid volume of saturated sodium chloride storage brine and an upper fluid volume of wet hydrocarbon storage fluid, surface fluid handling means; conduit connecting the lower storage brine and upper storage hydrocarbon fluid with the surface fluid handling means, of fluid transfer means enabling transfer of brine and hydrocarbon fluid from the surface to the cavern and from the cavern to the surface, such that brine can be added to or withdrawn from the lower brine volume and hydrocarbon fluids can be added to or withdrawn from the upper hydrocarbon fluid volume, and at least one desiccant drier means positioned at the surface in operable association with the surface fluid handling means whereby the wet hydrocarbon fluid upon withdrawal from the cavern passes through the desiccant drier means and thereby becomes dry, and dry hydrocarbon fluid intended for storage passes through the desiccant drier prior to entering the storage cavern and thereby becomes wet.
