Deep dives
The Science and Process of Helium Production
Helium is produced through the natural decay of radioactive materials like uranium and thorium over millions of years, releasing helium atoms into sedimentary rocks. Extraction involves drilling into these layers, similar to natural gas production, where companies like ExxonMobil collect helium as a byproduct. This process can be intricate and involves significant costs, such as drilling rig mobilization and day rates. The helium then undergoes purification, where impurities are removed to achieve varying grades of purity depending on its intended use.
