Denmark’s Alum Shale Contains 6.9 Tcf of Gas, Says USGS

The US Geological Survey estimated that the Alum Shale in Denmark contains 6.9 trillion cubic feet of undiscovered, technically recoverable natural gas, according to a note released on Tuesday.

"This is a potential resource for Denmark, although there is no current production there," said USGS Acting Director Suzette Kimball. 

The Alum Shale is part of the Baltic Basin and is made up of two assessment units, the onshore portion and the offshore portion. The offshore area was estimated to contain a mean of 4.4 trillion cubic feet of gas and the onshore area was estimated to contain 2.5 trillion cubic feet of gas. 

"The complicated geology in Denmark and the difficulty involved in assessing it really demonstrates how important it is to have a robust geologic model underpinning all of our assessments," Kimball explained.
