Abstract
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).
