ABSTRACT:
A method for offloading and storage of liquefied compressed natural gas into a salt dome by using inserting displacement gas with a pressure greater than a pressure of the liquefied compressed natural gas and a temperature of from about 80 degrees Fahrenheit to about 120 degrees Fahrenheit into a created cavern in the salt dome. The liquefied compressed natural gas is offloaded from the vessel to the storage cavern, wherein the liquefied compressed natural gas is at a pressure of from about 750 psi to about 1100 psi and a temperature of from about −80 degrees Fahrenheit to about −110 degrees Fahrenheit. The liquefied compressed natural gas is mixed with gas vapor in the storage cavern, wherein the gas vapor in the storage cavern is at a geostatic temperature and at a pressure lower than a pressure of the liquefied compressed natural gas.
