Investor site StreetAuthority is gushing over the potential of other shale fields in the United States. It says one shale formation in particular now being explored in Texas could hold as much as 30 billion barrels of recoverable oil and fuel, dwarfing the estimated 4.3 billion barrels in North Dakota's Bakken shale.



Street Authority writes: "Devon's wells show that the formation contains 3.6 million recoverable barrels of oil per square mile. As the Cline is roughly 9,800 square miles in size, this works out to estimated reserves in excess of 30 billion barrels. 



"These reserves could easily eclipse the Bakken (4.3 billion barrels according to conservative government estimates) and the Eagle Ford (3 billion barrels).  



"Something I should point out here is that the numbers quoted above are subject to change, have changed often in the past and can vary wildly depending on your source."
