Helium (He) accounts for 23% of the entire universe, the content only less than hydrogen, but helium has a low density, which is a rare gas. At present, industrially valuable helium (>0.1%) is mainly extracted from natural gas reservoirs with a content of up to 7.5%. In recent years, the liquefied natural gas (LNG) industry has emerged, and helium gas can be enriched in LNG tail gas, which can further reduce the industrial standard of helium.
According to the US Geological Survey, the amount of global helium resources currently detected is about 51.9 billion cubic meters. The United States is the world’s most resource-rich country. Although it has been exploited for more than 60 years, the amount of helium resources still accounts for more than 40% of the world’s total resources. According to a survey by the US Geological Survey in 2016, the United States, Algeria, Qatar, and Russia have 88% of the world’s helium resources. The global distribution of helium resources is as follows: 20.6 billion cubic meters in the United States, 10.1 billion cubic meters in Qatar, 8.2 billion cubic meters in Algeria, 6.8 billion cubic meters in Russia, 2 billion cubic meters in Canada, 1.1 billion cubic meters in China, and 3.1 billion cubic meters in other countries. .
