According to a team of researchers, the gas field located in southern Sweden formed under the process of glacier melting and complex biosphere reactions only 12,000 years ago.
Other shale gas fields formed nearly 300,000 years ago. As a result, the new Swedish gas field is considered "one of the youngest" in the world.
According to the researches, the field can produce gas at a depth of 100 meters.
In late-2014 scientists said companies profit from shale gas production in the US until 2020 only because oil fields in the country are not as rich as they were believed to be.
