One problem with ND natural gas is that it have very little recoverable helium gas in it.

In the central-South, especially Texas, there were lots of radioactive elements, whose breakdown products are rare earth elements and helium. When these elements were trapped in, then released helium from granite, the gaseous helium was integrated in the underground natural gas formed there.

So you need a combination of things to generate helium. The right kind of radioactive elements, the right kind of granite to trap them in, and enough natural gas to act as a carrier, easier to recover than helium alone.

Very, very few natural gas fields have economically recoverable helium. The reason the National Helium Reserve was created was it was so hard to find.
