There are many shale formations in the United States that have yet to be tapped and fracked, reports The Texas Tribune. Among them, the Cline shale in Texas is just starting to be explored.
The Tribune: “It is coming, and it is big,” said Greg Wortham, the mayor of Sweetwater [Texas], who also serves as executive director of the Cline Shale Alliance, a new economic development group.
"The Cline Shale, thousands of feet underground in a roughly 10-county swath, is just one of many little-tapped shale formations in Texas and across the nation, geologists say. That means the potential for oil and gas discoveries is theoretically huge, and the reason is technology. The rock-breaking process known as hydraulic fracturing, coupled with the ability to drill horizontally underground, has allowed drillers to retrieve oil and gas from previously inaccessible areas.
"Many shales will be too expensive or too small to develop, especially if oil prices fall or environmental regulations tighten."
