According to a new study just released by the Utah Geological Survey (UGS), Utah’s potential economic oil-shale resource equals approximately 77 billion barrels of shale oil. While the estimate is considerably smaller than numbers frequently quoted, it is still deserving of attention. “A domestic resource of this size is very significant; a conventional field with just 1 billion barrels is considered a ‘giant’,” says Michael Vanden Berg, UGS Project Geologist.
