Helium Hubbert peak theory
helium production , storage in united states, 1940–2014 (data usgs)
almost helium on earth result of radioactive decay of uranium , thorium. helium extracted fractional distillation natural gas, contains 7% helium. world s largest helium-rich natural gas fields found in united states, in hugoton , nearby gas fields in kansas, oklahoma, , texas. extracted helium stored underground in national helium reserve near amarillo, texas, self-proclaimed helium capital of world . helium production expected decline along natural gas production in these areas.
helium, second-lightest chemical element, rise upper layers of earth s atmosphere, can forever break free earth s gravitational attraction. approximately 1,600 tons of helium lost per year result of atmospheric escape mechanisms.
