Didnt see it as a daily consumption but you are right about that. It would need to be about 60 times the size of that one field. I would still be willing to bet that they have way more land then that filled with dead wells and a PBR never dies. Best comparison that I can give you without a crapload of math would be
US crude-oil production capacity, about 5 million barrels per day, is accomplished with about 510,000 oil wells, averaging 10.5 barrels per well per dayhttp://www.gravmag.com/production.shtml
A 10 acre PBR will produce the same as an average oil well at (guessing) 1\10 the cost.
No matter how you twist the numbers this is money in the bank
