Although helium is the second most common element in the universe, it is relatively uncommon on earth.

This essential element is the product of radioactive decay of thorium and uranium. Some of the helium generated migrates upwards along fractures and through permeable rocks, eventually accumulating in the subsurface along with other inert gases and/or hydrocarbons.

Because of its small size and low-density, helium is very difficult to trap. Once it reaches the surface it quickly rises and dissipates into the atmosphere. The majority of atmospheric helium is lost as it escapes into space.

The first documented encounter with trapped helium occurred in 1903 in Dexter, Kansas. A well drilling for oil and gas blew out creating a gas geyser that wouldn’t burn. Analysis of that gas indicated that it contained 72% nitrogen, 15% methane, 1% hydrogen and 1.84% helium.

Analysis on gas wells in Alberta have shown helium content from trace amounts to over 4%. First Helium’s initial discovery well contains 1.3% He.
