Natural gas resources still untapped were estimated at 5.8 Tcf, with crude oil resources of around 703 million bbl, the U.S. Geological Survey (USGS) said.

The Niobrara is a broad formation that contains a mix of limestone, chalk and shale. Most exploration and production (E&P) companies have found success within the Niobrara’s Denver-Julesburg (DJ) Basin and the Powder River Basin (PRB).
