It turns out that the oil industry has been pulling our collective leg.
The pending 96 percent reduction in estimated deep shale oil resources in California revealed last week in the Los Angeles Times calls into question the oil industry's premise of a decades-long revival in U.S. oil production and the already implausible predictions of American energy independence. The reduction also appears to bolster the view of long-time skeptics that the U.S. shale oil boom--now centered in North Dakota and Texas--will likely be short-lived, petering out by the end of this decade. (I've been expressing my skepticism in writing about resource claims made for both shale gas and oil since 2008.)
California has been abuzz for the past couple of years about the prospect of vast new oil wealth supposedly ready for the taking in the Monterey Shale thousands of feet below the state. The U.S. Energy Information Administration (EIA) had previously estimated that 15.4 billion barrels were technically recoverable, basing the number on a report from a contractor who relied heavily on oil industry presentations rather than independent data.
