While outer space is overflowing with Helium, its presence deep under the earth’s crust makes it difficult to harvest. How Is Helium Extracted? Helium is mined along with natural gas, using a drill rig to drill wells deep into the earth’s crust. A drill rig must penetrate a layer called the Cap Rock to reach a natural gas reserve.

Helium is mined alongside natural gas. This is a long process where a drill is used to drill wells very deep into the crust of the Earth. The drill rig has to penetrate the layer of the crust called Cap Rock in order to reach any natural gas reserves.
