Helium-rich natural gas reservoirs contain helium that has accumulated with other subsurface gases, commonly after generation by radioactive decay of uranium and thorium in crustal rocks. Helium migrates through the subsurface and may become concentrated in suitable reservoir rocks beneath effective seals. Commercial potential depends on helium concentration, reservoir size, gas composition, and recovery economics.
The following Elements and Minerals may be found in this Deposit Type.
No mineral relationship. Helium is recovered from helium-bearing subsurface gas accumulations, commonly natural-gas reservoirs.
