From what natural resource is most helium extracted?

Most helium is extracted from natural gas. This is due to the unique geological processes that lead to the formation of natural gas reservoirs, where helium can accumulate in significant concentrations. Helium is not commonly found in the atmosphere or in coal and water; therefore, natural gas becomes the primary source for helium extraction.

During the extraction of natural gas, helium often comes along because it is a product of the radioactive decay of elements in the Earth's crust over millions of years. Thus, when natural gas is processed, helium is separated and collected. This process is crucial not only for providing helium for various applications but also for understanding the geologic conditions favorable for helium deposition.
