Vast shale oil field in Texas could yield 20 billion barrels
November 17, 2016
DALLAS (AP) -- A vast field of shale rock in West Texas could yield 20 billion barrels of oil, making it the largest source of shale oil the U.S. Geological Survey has ever assessed, agency officials said.
The Wolfcamp Shale geologic formation in the Midland area also contains an estimated 16 trillion cubic feet of natural gas and 1.6 billion barrels of natural gas liquids, the agency said in a release.
The discovery is nearly three times larger than the shale oil found in 2013 in the Bakken and Three Forks formations in the Dakotas and Montana, said Chris Schenk, a Denver-based research geologist for the agency.
Geologists explain that oil recovered from shale rock is considered unconventional compared to other oil found in the ground because extracting it requires advanced drilling or recovery methods, such as hydraulic fracturing.
The Wolfcamp Shale is part of the sweeping and energy-rich Permian Basin, which includes a series of basins and other geologic formations in West Texas and southern New Mexico. It's one of the most productive oil and gas regions in the U.S.
Ken Medlock, director of an energy-studies program at Rice University in Houston, said it seems "likely that we're seeing the birth of a new Permian Basin." The advent of horizontal drilling, hydraulic fracturing and other advancements will allow for the removal of shale oil at a volume that will make the basin "the dominant onshore platform for oil production," he said...
