yep.
And I thought the only way to get the oil was to cook it.
Pretty much. It is locked in a near or at surface shale, too shallow to frac and with no overburden pressure to force it into a reservoir. Much of the Book Cliffs area has exposures of the Green River Shale.
As an aside, the US Govt. tried freeing the hydrocarbons a few decades back with a small nuclear device. That didn't produce the desired results. There was also a pilot project to cook the oil out of the mined shale at Parachute, CO, (UNOCAL, I think). It shud down in the '80s when the price of oil crashed, and would likely be EPA'd out of existence today.
Reading the actual report, the oil is buried very deep, not at the surface.
