Two Trillion Barrels

The Green River Shale Formation encompassing the States of Colorado, Utah and Wyoming was first discovered in 1924.
This famous shale formation covers tens of thousands of square miles. It is found in three different ancient lake basins. The layers of sediment in this formation stretch undisturbed for many miles.

This shale is a soft sedimentary rock that readily fractures into layers, composed of minute particles of clay, which may easily be removed. It was formed from multi layers through erosion. There are 40 million layers in one part of this formation.
Deposits within these layers are fossilized plant, animal life and algae, which has turned over millions of years into kerogen..so do we have more crude or not...thats the question.. some say we have ...Two Trillion Barrels ...
