The helium companies involved in the operation sued the United States government for breach of contract.

Since the early 20th century, most of the world's helium supply has been extracted from natural gas as part of the nitrogen rejection process. The preference for primary helium is driven by the planned reduction in use ...
The National Helium Reserve, also known as the Federal Helium Reserve, is a strategic reserve of the United States, which once held over 1 billion cubic meters (about 170,000,000 kg) [a] of helium gas. The helium is stored at the Cliffside Storage Facility about 12 miles (19 km) northwest of Amarillo, Texas, in a natural geologic gas storage ...
