Uh oh, we need more wells and more pools of oil.   And that 36" line may not be big enough.  After all, a tanker can load maybe 2,000,000 barrels, and your total would only fill 3 tankers.  But I like your math.  We just need more oil fields now and maybe we could get to 60,000,000 bbls and then we could be outta there in 90 days.  And the pps would be what?  Youza!  Oh my.  Get Ready!
