The United States has 800 Billion Barrels of Oil Shale locked up in Wyoming and Colorado, that’s enough to supply the whole World for 60 years, and inventor Byron Merrell has developed a method of Oil shale recovery that can extract oil for $33 dollars a barrel. His Petrosix process is next going to be tried in a plant that can produce 1,000 barrels a day. If successful larger projects could whittle the price down to under $20 a barrel.
