<p>A method of storing high-viscosity, non-pumpable, hydrocarbon materials in subterranean storage facilities is provided. The method comprises the sequential steps of purging the storage facilities with a carbon dioxide-containing fluid to provide a carbon dioxide atmosphere therein, admixing an effective amount of carbon dioxide with the hydrocarbon material to sufficiently lower the viscosity of the hydrocarbon material, injecting the carbon dioxide-containing hydrocarbon material into the storage facilities, and maintaining a carbon dioxide atmosphere in the facilities while same contains the carbon dioxide-containing hydrocarbon.</p> |
