America Is Sitting on the World's Largest Oil Deposit — But There's One Problem

Summary

The video explains why the Green River Formation—beneath parts of Colorado, Utah, and Wyoming—is often described as an enormous oil resource, yet has never produced oil commercially. Its central point is that the barrier is not whether the rock can be converted into oil, but whether that can be done profitably and sustainably.

Main Ideas

• A huge resource, not a developed oil field: A 1915 government geological survey drew attention to the formation’s potential. Modern estimates put the hydrocarbons in its rocks at roughly 3 trillion barrels. The video stresses that this is a resource estimate—the total amount thought to be present—not the amount that can be profitably extracted. Commercial production from the formation remains at zero.

• Why the rock is different: Around 50 million years ago, freshwater lakes in the region accumulated algae and other organic matter. Burial and heat changed this material into kerogen, a waxy solid, but the natural process did not continue far enough to form liquid crude oil. The rock therefore needs additional heating before its hydrocarbons can be extracted.

  • The video distinguishes oil shale (rock containing solid kerogen) from shale oil (liquid crude oil in formations such as those developed in Texas and North Dakota).

• The 1970s oil boom and Exxon’s project: The 1973 oil embargo and resulting fuel shortages renewed interest in domestic energy. Exxon invested heavily in a project near Parachute, Colorado, planning to mine the rock, heat it in large facilities, and build a company town at Battlement Mesa. The area expanded rapidly, but in May 1982—“Black Sunday”—Exxon abruptly shut the project down. Workers lost their jobs, families were told to leave, and local growth plans collapsed.

• The two main obstacles:

  1. Energy use: The rock must be heated to more than 750°F to convert kerogen. Supplying that heat can consume so much energy that the process may not generate enough value to justify its cost. Profitability also depends on oil prices remaining high enough for long enough.
  2. Water: Some methods may require many barrels of fresh water for each barrel of oil produced. That is a major concern in the dry American West, where the Colorado River already serves cities and farms across several states and northern Mexico.

• Later approaches have not solved the economics: Chevron conducted pilot projects, while Shell tested heating the rock underground with electric elements over a long period, rather than mining it and heating it above ground. Shell’s approach produced oil in tests, but it still did not prove economically competitive with conventional extraction.

• Competition from other oil sources: Advances in fracking made it cheaper to extract liquid crude from formations in Texas and North Dakota. This reinforced the key economic comparison: converting kerogen into oil must compete with other ways of obtaining oil.

• The outlook is uncertain: Improvements in in-situ heating and water conservation may have narrowed the gap between technical feasibility and commercial viability, but the video says that gap remains. Whether the resource is ever developed depends on future technology, water constraints, oil prices, and costs—not simply on how much hydrocarbon is underground.
