The geological structure of the area is suitable for large underground natural gas storage facilities. The salt formation covers an area of 30 km 2 (12 sq mi). It is 15 km (9.3 mi) long and around 2.0–2.5 km (1.2–1.6 mi) thick. It has a salt dome structure. To create the caverns in the salt formation, fresh water was brought by pipeline ...
Once created, a salt cavern offers an underground natural gas storage vessel with high deliverability. Cushion gas requirements are lower, typically about 33 percent of total gas capacity. Salt caverns are usually much smaller than depleted gas reservoir and aquifer storage facilities. A salt cavern facility may occupy only one one-hundredth of ...
Some salt domes can be seen from Earth's surface. They can also be located by finding unique surface structures and surrounding phenomena. For instance, salt domes can contain or be near sulfur springs and natural gas vents. [4] Some salt domes have salt sheets that extrude from the top of the dome; these are referred to as salt plugs.

The Bayou Corne sinkhole (French: Doline de Bayou Corne) was created from a collapsed underground salt dome cavern operated by Texas Brine Company and owned by Occidental Petroleum. The sinkhole , located near the community of Bayou Corne in northern Assumption Parish , Louisiana , was discovered on August 3, 2012, and 350 nearby residents were ...
Since 1994, AGL Resources has used Lake Peigneur's underlying salt dome as a storage and hub facility for pressurized natural gas. [13] [14] There was concern from local residents in 2009 over the safety of storing the gas under the lake and nearby drilling operations. [15]
To make larger volumes of gas available in the winter, companies have established underground gas storage facilities. There are three types of natural gas storage units currently in service in the US: salt domes, depleted gas reservoirs, and deep aquifers. [26] The largest volume held in storage was 8.29 trillion cubic feet in October 2012.
A salt dome shed near Woodburn Road and Grandview Boulevard in Waukesha collapsed at about 3:40 p.m. Tuesday at the county highway operations center.
