PEAK OIL NOW

note:
Someone asked [url]oil-price.net[/url] about the size of a barrel of oil. The answer is tricky:
Oil coming out of a well is measured in 42 gallon barrels. That is the old US barrel volumetric unit. However when oil leaves the oil fields in trucks, it is packaged in 55 gallon drums (English imperial barrel volumetric unit).

Suppose your well outputs 1,000 barrels of oil per day. That's 42,000 gallons of oil. The truck (or train rather) leaving the gate has 764 barrels of oil in it. Still you just sold 1,000 barrels.

This is because the barrel used to measure oil production (42 gal) and the barrel used to transport oil (55 gal) are different.
