A new exploration method leads to huge helium discovery in Tanzania, securing the world's supply of helium.

Humankind is running out of Helium gas. Helium doesn't just make your voice squeaky, it is critical to many things we take for granted, including MRI scanners in medicine, welding, industrial leak detection and nuclear energy.

Helium has never been found intentionally. The discoveries of helium are all accidental.

A research group from Oxford and Durham universities, working with Helium One, a helium exploration company headquartered in Norwaym, developed a new method to discover helium.

The first use of this method has resulted in the discovery of a world-class helium gas field in Tanzania.

Their research shows that volcanic activity provides the intense heat necessary to release the gas from ancient, helium-bearing rocks.

Within the Tanzanian East African Rift Valley, volcanoes have released helium from ancient deep rocks and have trapped this helium in shallower gas fields.

The research is being presented by Durham University PhD student Diveena Danabalan at the Goldschmidt geochemistry conference in Yokohama, Japan.

Diveena Danabalan, of Durham University's Department of Earth Sciences, said: 'We show that volcanoes in the Rift play an important role in the formation of viable helium reserves. Volcanic activity likely provides the heat necessary to release the helium accumulated in ancient crustal rocks. However, if gas traps are located too close to a given volcano, they run the risk of helium being heavily diluted by volcanic gases such as carbon dioxide, just as we see in thermal springs from the region. We are now working to identify the 'goldilocks-zone' between the ancient crust and the modern volcanoes where the balance between helium release and volcanic dilution is 'just right'.'

Professor Chris Ballentine, Department of Earth Sciences, University of Oxford, said: 'We sampled helium gas (and nitrogen) just bubbling out of the ground in the Tanzanian East African Rift valley. By combining our understanding of helium geochemistry with seismic images of gas trapping structures, independent experts have calculated a probable resource of 54 Billion Cubic Feet (BCf) in just one part of the rift valley. This is enough to fill over 1.2 million medical MRI scanners. To put this discovery into perspective, global consumption of helium is about 8 BCf per year and the United States Federal Helium Reserve, which is the world's largest supplier, has a current reserve of just 24.2 BCf. Total known reserves in the USA are around 153 BCf. This is a game changer for the future security of society's helium needs and similar finds in the future may not be far away.'
