Underground Hydrocarbon Storage Unit

The Underground Hydrocarbon Storage (UHS) program regulates the storage of natural gas, liquefied petroleum gas (LPGs), and liquid hydrocarbons in underground caverns developed in the Hutchinson Salt Member of the Wellington Formation. As of 2019, there are 9 active storage facilities, 368 active status storage wells and caverns with a storage capacity of ~73 million barrels, and 49 brine ponds. To see a complete overview of the UHS program and for more information about the geology of the area and cavern development please see the Underground Hydrocarbon Storage Program Overview 2019 (PDF).
