I wonder if it is possible to “frack” the shale in the Green River Formation.

Apparently, rumours of ‘peak oil’ were exaggerated.

Wells that were non profitable at $40/barrel can make good money at $80 a barrel.

I don't see this as disproving peak oil, particularly in the USA.

“I wonder if it is possible to “frack” the shale in the Green River Formation.”

Shell has a system.

I don’t know; but, a couple of decades ago, the received wisdom held that the Alberta oil sands couldn’t be developed economically. They are now the greatest single source of oil imported into the U.S.

The “oil shale” rock in the Green River formation for the most part is not really shale at all and contains kerogen, a solid, not oil. It needs to be heated to a few hundred degrees for a few months or to a much higher temperature for a shorter period of time to cook down / reduce the kerogen to a liquid.

Too bad that the gas and oil trapped in immpermiable shales [otherwise impermiable until fracture stimulated] sounds a bit like “oil shale.” The two are much different form of hydrocarbons.
