This feature class/shapefile represents Natural Gas Underground Storage Facilities. Natural gas may be stored in a number of different ways. It is most commonly held in inventory underground under pressure in three types of facilities. These underground facilities are depleted reservoirs in oil and/or natural gas fields, aquifers, and salt cavern formations. Some Natural Gas Underground Storage Facilities may have duplicate names but these will have differing Reservoir names as defined by the EIA.
