Abstract: The subterranean storage facility includes a subterranean cavern forming an underground cavity in which is disposed an immiscible displacing liquid. A plurality of concentric pipes extend from the surface into the cavity. As a cold fluid at a sub-zero temperature is passed down a first flow bore formed by the concentric pipes, the immiscible displacing fluid is passed in heat exchange relationship up a second flow bore formed by the concentric pipes. The cold fluids are then stored within the cavity at a temperature and pressure consistent for safe storage.

Abstract: A method of handling solid particles is disclosed, comprising the steps of mixing the solid particles with a clay and water and forming a suspension wherein the solid particles remain suspended. The suspension is transported to an emplacement site.

Abstract: The offshore facility and terminal includes a plurality of underground salt caverns located beneath the ocean floor. An offshore platform is located above the caverns and includes a flow line to a single point mooring for connection to a supertanker. A well extends from the platform into the underground salt caverns for the flow of hydrocarbons. The hydrocarbons are stored in the underground salt caverns with an immiscible displacing fluid, such as brine. The hydrocarbons and brine are immiscible and have different densities such that the brine settles at the bottom of the underground cavern. Another well extends from the underground cavern to a displacing fluid reservoir. This reservoir is a brine pond located in a depression in the ocean floor. The brine is pumped to and from the brine pond and into the underground cavern to assist in the off-loading and removal of the hydrocarbons.

Abstract: A subterranean cavern having gas impermeable walls is used to store grain. The cavern has a controlled atmosphere without oxygen and preferably has an atmosphere of nitrogen. Access is provided to the cavern from the surface for the loading and outloading of the grain stored in the cavern. The grain is loaded into the cavern by conveying the grain to the access and then either allowing the grain to fall through the access into the cavern or by pneumatically conveying the grain into the cavern. The grain is outloaded from the cavern by a pneumatic conveyance system.
