Casper, WY – The U-S Energy Department is planning to inject carbon dioxide into underground oil reservoirs at the Teapot Dome north of Casper. The project could be one of the world's largest test sites for burying C-O-2 in hopes of slowing global warming. The Teapot Dome project will store carbon dioxide from a natural gas processing plant more than 300 miles away beneath the oil field in central Wyoming. Project Manager Vicki Stamps says the process has been tested at smaller sites nationwide but never on such a large scale. Storage could begin by 2006 and last seven to ten years.
