It doesn't matter because all of that oil belongs to the multinational companies who extract it, and they will only extract enough that assures them the highest possible profits.
Grow up.
The more supply is increased, the lower oil company profits are because the lower the price per barrel is.
That is why they don't drill...because doing so means more supply and lower prices and that runs in direct conflict with capitalism.
To put it even simpler:
What is most profitable for the company? 1,000 barrels @ $100/barrel, or 10,000 barrels @ $1/barrel? I know that's tricky math for you, but I believe in you!
