Life-saving discovery: Helium gas reserve found in Tanzania
Scientists, using a new approach to gas exploration, have discovered a huge helium gas field in Tanzania, which could address the increasingly critical shortage of this vital yet rare element.
Helium is critical to many things we take for granted, including MRI scanners in medicine, welding, industrial leak detection and nuclear energy . Until now helium has never been found intentionally -being accidentally discovered in small quantities du ring oil and gas drilling.
Researchers from Oxford and Durham universities in the UK, working with Helium One, a helium exploration company in Norway , has developed a new exploration approach. The first use of this method has resulted in the discovery of a world-class helium gas field in Tanzania.
The 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.
"By combining our understanding of helium geochemistry with seismic images of gas trapping structures, experts have calculated a probable resource of 54 billion cubic feet in just one part of the rift valley," Chris Ballentine, Professor at the University of Oxford said.
