Calculate the total quantity of petroleum produced in 20th Century.
Expressed in Cubic Feet (iow: cubic area) (not in Joules nor BTUs etc)
NOTE:
1 Cubic Feet = 7.48052 US Liquid Gallon
Factoid:
Fossil fuels [oil, coal, natural gas] hydro, solar, and nuclear power are referred to as primary energy.
World consumption of primary energy increased from 1965 to 2007: 3.8 billion tonnes of oil equivalent to 11.1 billion tonnes of oil equivalent.
NOTE:
The barrel of oil equivalent (BOE) is a unit of energy based on the approximate energy released by burning one barrel (42 U.S. gallons or 158.9873 litres) of crude oil.
So, if we can calculate the cubic feet of petrol taken out of earth + coal extracted .... and then compare that Cubic Feet of Mass to known masses ....it will paint a better picture of the ratio of:
cubic feet of the earth's atmosphere versus
versus
cubic feet of all the gallons and coal volume extracted
NOTE:
Total Water on Earth = 332,500,000 cubic miles (mi3) (1,386,000,000 cubic kilometers (km3)).
Total Atmosphere of Earth = 3,095 cubic miles (12,900 cubic km).

Other source:
All the water in the world (1.4087 billion cubic kilometres of it) including sea water, ice, lakes, rivers, ground water, clouds, etc.
All the air in the atmosphere (5140 trillion tonnes of it) [At sea level, a cubic foot of atmosphere weighs about an ounce and a quarter].
MY POINT ---my Speculation:
All the petrol extracted from the ground is a Hoax. I speculate that motor petrol, gasoline is 99% laboratory-made concoctions.
Bio-fuel technology has made Oil drilling obsolete and unnecessary ... maybe I wrong ---so, I'd adjust and say that a gallon of crude oil can yield 100,000 gallons of high-octane gas good enough for most uses.
