The cavern of oil goes all the way inland under Alabama, etc.
It can pump 500,000 barrels a day for ten years!
That about one normal tanker a day.
About what one normal to large refinery can handle every day.
So right there, P O O F , instant under $2 gasoline.
Plus, that much less money for our enemies(the Saudis) to buy arms for their pals.
Let's say all of that is true. But what about SECURITY? Such pressurized jugular veins would be sweet and easy targets for our enemies, at the time of their choosing. What happens if we go to war? What happens if a dozen of these are all sabotaged and/or torpedoed?
Underground oil is not normally in caverns, but in regions of porous rock.
It can pump 500,000 barrels a day for ten years!
No, it can't. The 500,000 BPD figure is an estimate of the decrease of production in the Gulf of Mexico from declaring a moratorium on new wells for one year.
My (limited) research indicates that upper level figures for the amount of oil that could come out of this well are about 60,000 BPD, and I did not see anything about 10 years.
