(Thu, 22 Sep 2011) The U.S. has three primary types of underground natural gas storage facilities: depleted fields, aquifers, and salt caverns. Depleted natural gas fields provide by far the largest share of natural gas storage capacity and together with aquifer storage are used primarily to meet seasonal delivery needs. Most new storage facilities built since 2007 have been salt caverns.
