Federal energy authorities have slashed by 96% the estimated amount of recoverable oil buried in California’s vast Monterey Shale deposits, deflating its potential as a national “black gold mine” of petroleum.
Just 600 million barrels of oil can be extracted with existing technology, far below the 13.7 billion barrels once thought recoverable from the jumbled layers of subterranean rock spread across much of Central California, the U.S. Energy Information Administration said.
The new estimate, expected to be released publicly next month, is a blow to the nation’s oil future and to projections that an oil boom would bring as many as 2.8 million new jobs to California and boost tax revenue by $24.6 billion annually.
Compared with oil production from the Bakken Shale in North Dakota and the Eagle Ford Shale in Texas, “the Monterey formation is stagnant,” Staub said. He added that the potential for recovering the oil could rise if new technology is developed.
A spokesman for the oil industry expressed optimism that new techniques will eventually open up the Monterey formation.
