Helium usually makes up a minuscule portion of natural gas, but can make up as much as 10 percent of natural gas in some fields. A helium content of 0.3 percent or more is considered necessary for commercial helium extraction. [1] In 2012, helium was recovered at 16 extraction plants, from gas wells in Colorado, Kansas, Oklahoma, Texas, and ...
The helium companies involved in the operation sued the United States government for breach of contract. The owners of the land containing the natural gas from which helium was separated as a side-product sued the government for the value of the helium, as they were unable to sell it to third parties.

Pure-play helium, also known as primary helium or green helium is helium that is extracted from the earth as the main product. 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 ...

Because helium is trapped in the subsurface under conditions that also trap natural gas, the greatest natural concentrations of helium on the planet are found in natural gas, from which most commercial helium is extracted. The concentration varies in a broad range from a few ppm to more than 7% in a small gas field in San Juan County, New Mexico.

A natural-gas processing plant in Aderklaa, Austria. Natural-gas processing is a range of industrial processes designed to purify raw natural gas by removing contaminants such as solids, water, carbon dioxide (CO 2), hydrogen sulfide (H 2 S), mercury and higher molecular mass hydrocarbons to produce pipeline quality dry natural gas [1] for pipeline distribution and final use. [2]
Helium is also present as up to 7% of some natural gas sources, [20] and large sources have over 0.5% (above 0.2% makes it viable to extract). [21] The fraction of 3 He in helium separated from natural gas in the U.S. was found to range from 70 to 242 parts per billion.
