Helium production in the United States totaled 73 million cubic meters in 2014. The US was the world's largest helium producer, providing 40 percent of world supply. In addition, the US federal government sold 30 million cubic meters from storage. Other major helium producers were Algeria and Qatar.
All commercial helium is recovered from natural gas. 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. In 2012, helium was recovered at 16 extraction plants, from gas wells in Colorado, Kansas, Oklahoma, Texas, and Wyoming. One extraction plant in Utah was idle in 2012.
