A method of forming a subterranean gas storage vessel is provided. A wellbore is drilled through the surface of the ground into the ground, and a casing is inserted into the wellbore, the casing having a size such that a wellbore annulus is formed between the outside surface of the casing and the wall of the wellbore. A cement sheath is then formed in the wellbore annulus, and the interior of the casing is sealed to help prevent gas from inadvertently escaping therefrom. The cemented and sealed casing can then be used as a storage vessel to store and dispense gas such as compressed natural gas (CNG). L'invention concerne un procédé de formation d'une cuve de stockage de gaz souterraine. Un puits de forage est foré à travers la surface du sol dans le sol, et un tubage est inséré dans le puits de forage, le tubage ayant une taille de telle sorte qu'un espace annulaire de puits de forage est formé entre la surface extérieure du tubage et la paroi du puits de forage. Une gaine de ciment est ensuite formée dans l'espace annulaire de puits de forage, et l'intérieur du tubage est scellé pour aider à empêcher un gaz de s'en échapper par inadvertance. Le tubage scellé et cimenté peut ensuite être utilisé comme cuve de stockage pour stocker et distribuer un gaz tel qu'un gaz naturel comprimé (CNG).
