Complex fold in California's Monterey formation.
The Monterey formation has a complex burial history. This fold shows how potential oil bearing shale has been complexly deformed by California's active tectonics.
Like a mirage, 96% of the potential oil reserves in California's Monterey formation vanished into thin air, because they never existed, naturally leaked out, or cannot be recovered economically. The incredible projections of billions in wealth and 2 million new jobs had no geologic basis.

Areas in California's Monterey formation where fracking is being considered to recover tight oil in shale.
The natural production of oil in rock is a complex factor of the temperature and burial history of the sediments that contain organic matter capable of becoming oil. If the sediments aren't buried deeply enough the organic matter does not "mature" enough to become oil. It's just dirty rock. If the sediment is buried too deep and gets too hot for too long gas may be produced. If there isn't a good cap rock the gas may escape into the atmosphere along fractures or faults. Oil may also form naturally in the shale, then migrate to the surface along faults then biodegrade over time. Sometimes, faults act as traps, other times faults create vertical conduits. Like the Goldilocks story, the temperature, burial history and geology has to be just right to produce recoverable oil. The new U.S. government estimates, which considered the geologic complexity of the oil-bearing shale deposits in California's Monterey formation, determined that the previous contractor determined estimate, based on a simple layer cake model of California's geology, was about twenty five times higher than a realistic estimate based on the complex burial, folding and faulting in California's highly active geologic setting.

Most of the Monterey formation in California does not contain oil reserves.

Large oil fields are associated with the deep basins in the Monterey formation in the Salinas valley but the majority of the Monterey formation in the Salinas valley shown in yellow orange and red  is too shallow to contain oil.
Most of the oil producing rock in the Monterey formation in the Salinas valley is too shallow to contain oil. Only the areas around the deep basins, in blue and green produce oil.
Large amounts of oil have already been produced in California by traditional means from traditional oil traps. Oil that formed naturally in the shale units in the Monterey formation has already migrated to higher porosity rocks sealed by impermeable cap rocks. Very little oil may remain in large volumes of shale.
Based on our drilling results, our view is that the oil has migrated out of the formation and is now found in pockets outside of the Monterey shale,’ said Kurt Glaubitz, a spokesman for San Ramon, California-based Chevron, the second-biggest U.S. oil producer.
The inflated estimate of oil reserves appears to have been done by a contractor that was shilling for fracking. In 2013, the Postcarbon Institute published a detailed report that debunked the incredible estimates of enormous amounts of oil in the Monterey formation. Apparently the federal government has independently reached the same conclusion. The federal government is now cutting its estimates of recoverable oil by 96%, reports the LA Times.
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.

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.

You can add a private note to this diary when hotlisting it:
