Helium production and storage in the United States, 1940-2014 (data from USGS) In 1903, an oil exploration well at Dexter, Kansas, produced a gas that would not burn.. Kansas state geologist Erasmus Haworth took samples of the gas back to the University of Kansas at Lawrence where chemists Hamilton Cady and David McFarland discovered that gas contained 1.84 percent
In reaction to depleting helium sources, the Helium Act of March 3, 1927 was established to prohibit the sale of helium to foreign countries and for non-governmental domestic use. [ 8 ] By 1937, a number of factors collided to move the United States government to revise its helium policy and create the Helium Act of September 1, 1937.
These fields contain natural gas with unusually high percentages of helium—from 0.3% to 2.7%—and constitute the United States' largest helium source. The helium is separated as a byproduct from the produced natural gas. After the Helium Acts Amendments of 1960 (Public Law 86–666), the U.S. Bureau of Mines arranged for five private plants ...
Helium is a commonly used carrier gas for gas chromatography. The age of rocks and minerals that contain uranium and thorium can be estimated by measuring the level of helium with a process known as helium dating. [28] [30] Helium at low temperatures is used in cryogenics and in certain cryogenic applications.
