Location of natural gas storage in relation to Hutchinson
The Yaggy Storage Field consists of 98 caverns in the Hutchinson Salt Member of the Wellington Shale at depths greater than 500 ft. The caverns were formed by salt dissolution using brine wells. The capacity of the facility has been reported as 3.2 billion cubic feet of natural gas. The caverns are accessed by wells located on a grid with less than 400 ft spacing between wells.

A pressure drop was recorded in well S-1, and subsequently a leak was discovered in well S-1 at a depth of about 601 ft. The cavern connected to well S-1 reportedly holds 60 million cubic feet of gas. The pressure inside the cavern ranges from 550 to 684 pounds per square inch (psi), and is normally kept at about 675 psi.
