America’s Biggest Oil Reserve May Be in Rocks

or
“Oil Shale” vs. “Shale Oil”

  

Hidden 1,000 feet beneath the surface of the Western Slopes of the Great Rocky Mountains, teams of engineers and scientists are working on an exploit of modern day alchemy: Turning rocks into oil. There lies the largest untapped oil reserve in the world - more than 2 TRILLION barrels.  These rocks are so rich in an oil-like substance that some pieces will ignite when held to an open flame.

According to a U.S. Geological Survey, a scientific agency of the United States Government, that’s 4 times the proven reserves of Saudi Arabia. And, it’s greater than all 12 OPEC countries combined, which have proven reserves of about 911 billion barrels of oil.

As you might guess formidable technical, economic, environmental, and political challenges must be dealt with before it will be a viable resource. None-the less, the potential benefits associated with tapping such an immense domestic energy supply is hard to ignore.

Regardless of the likely adversities, the allure of freeing the oil in these oil shale rocks has convinced some of the world's largest energy companies (and dozens of their smaller counterparts) to place big bucks on the future of oil shale.

Formed millions of years ago, oil shale is the result of circumstances of high temperatures and gravitational pressure that are necessary for the creation of petroleum; trouble is the situation didn’t last long enough for the complete creation of oil.  The result is oil shale, and some folks believe advances in technology will now allow scientists and developers to finish the job that Mother Nature started.  In a “nut shell” if these rocks are heated in just the right way, oil is released and can be collected to be refined.

In-any-event some oil recovery experts and economists say that Oil shale is a wasted investment, and an unnecessary resource to harness. They say targeting Oil Shale for oil recovery is now unnecessary because there is much more excitement and attention on the Shale Oil scene.

Yes, there are certainly huge amounts of oil locked up in shale formations worldwide. In the United States alone, the “Bakken” and “Eagle Ford” shale’s contain up to 700 billion barrels, and the Green River Oil Shale lying under Colorado, Wyoming, and Utah as indicated above, has a whopping 2 trillion barrels.

Though all of these deposits are loosely referred to as “shale oil,” the Bakken and Eagle Ford oil is more precisely called “tight oil,” because it is actually a fluid oil that is trapped in the pores of shale, and it can be liberated by “fracturing” (generally called fracking) the rock to allow the oil to flow. On the other hand, the oil in the Green River shale rock is not really oil at all but a waxy like substance that is more tightly bound up with the rock; the hydrocarbon (oil) found their must be heated to around 500 ° Celsius (932 ° F.) to turn it into flowing oil.

The technology for extracting oil from deposits like the Green River shale is far more challenging (considering the numerous obstacles mentioned in paragraph 3 above) than is required to tap into tight oil, and it has yet to be profitably implemented on a significant scale. For this reason there is no credible estimate of how much oil can be recovered from the Green River formation even though geologists know within reason how much is in-place.

Producers have been trying to accomplish oil extraction in one of two ways: Either they bring the shale to the surface and then “cook” it, or they sink a deep shaft and place a really expensive electric heater at the base, a process called “in-situ”. But thus far, the American Shale Oil Corporation (AMSO) has been testing in-situ with mixed success.

Some folks say the government has known for years that this land was saturated with oil and even though it was deemed too expensive to recover, in 1930 the government placed protective legislation on this land, forbidding anyone to touch it.    Then on August 8, 2005, President George W. Bush did something right, he signed into law The Energy Policy Act; a mandate lifting the protective legislation on the Green River Formation. 

The good news may be that since the federal government owns 80% of the land containing the Green River Formation, in theory at least, this could be a major source of income via oil lease production royalties.  Considering the excessive U S National Debt, currently at 14 Trillion Dollars and counting, this could be huge!    Many economists agree that as little as 30 percent of U S Government royalty revenue from the Green River Formation could be enough to pay off the entire national debt!  Imagine that!

Now get this: Because world oil prices are low /dropping, research and development programs (R & D) for new and improved Shale Oil recovery methods are doomed to deteriorate or at best maintain the status quo!  This may be good news for the average commuter but believe it or not that’s not good news for U S Oil Shale production in the Green River Formation.  So, thank of it this way, as the price of oil falls, some U S producers will become unprofitable and go out of business.   But then the price of oil is likely to stabilize!

The Energy Information Administration (EIA) has projected that US drivers will spend about $550 less on gasoline in 2015 than they did in 2014, that’s assuming prices remain low. So in theory at least, consumers will spend more money on other goods, which will improve the economy.  This projection is largely based upon a  Reuters Poll Survey taken in January of 2015 of 33 economists and analysts who forecast that North Sea Brent crude (a sweet light crude oil that serves as a benchmark price for purchases of oil worldwide) would average $58.30 a barrel in 2015.

As you can see, a fall in crude prices will have both positive and negative impacts on the typical American consumer. For many folks, it will offer a tremendous economic boost: cheaper oil means lower gasoline prices — which have fallen below $2.00 per gallon in many places.

So dropping oil prices is not all good news. Oil-producing states like Texas and North Dakota are likely to see a drop in revenues and economic activity. The falling price of oil is also putting severe pressure on Alaska’s state budget.     

All be told, oil prices are likely to be good for 42 states, and not so good in 8 states, as is shown in the illustration to the upper right.

In conclusion, it’s well worth while to further examine oil recovery methods from Oil Shale reserves, especially since the U.S. is sitting on the largest stockpile of oil shale in the world.  Oil Shale may eventually become part of the energy cycle, but by the time that it’s economically feasible, you will probably be long gone from this world.
