GTS anticipates commencement of full commercial service for approximately 6 billion cubic feet of working gas capacity upon completion of dewatering in December.
Construction of the surface facilities began in May 2008.
Solution mining began in February 2009 and involved injection and removal of water from the well drilled nearly one mile deep into the salt of the famed Spindletop Dome, site of the world’s first oil gusher.
During the next 15 months, the water dissolved a cylindrical-shaped cavern in the salt tall enough to contain the Empire State Building.
Pivotal Energy Development is using the same process of solution mining, or leaching, to create Cavern 2. When the second cavern is completed, it is expected that the facility will be able to store enough natural gas to supply 250,000 households for one year – approximately 12 billion cubic feet of working gas capacity.
Cavern operations are supported by a 14,025-horsepower compressor system and dual 24-inch pipeline header interconnected to six measurement stations in Jefferson and Orange counties in Texas.
The header and interconnect stations are bi-directional for injection and withdrawal by customers using the facility.
AGL Resources business unit Pivotal Energy Development president said that the caverns at Golden Triangle Storage, along with the planned expansion of our facility at Jefferson Island in Louisiana, are vital infrastructure projects that will help our company ensure that Americans enjoy the benefits of clean-burning and domestically abundant natural gas for years to come.
