Oil Energy Density

Energy density

It is the amount of energy stored in a given system or region of space per unit volume or mass. Often only the useful or extractable energy is measured, which is to say that chemically inaccessible energy such as rest mass energy is ignored.

It has the same physical formula as pressure. Thus technically it may be called as pressure too.

Oil Energy Density

Crude oil consists of a few organic compounds which include hydrogen, carbon, sulfur, and oxygen. Oil contains high energy density. That is it contains high amount of energy per kilogram. Petroleum or crude oil has a high energy density, which is approximately 45 MJ/kg.

Some calculations

Barrel of oil equivalent (boe) = approx. 6.1 GJ (5.8 million Btu), equivalent to 1,700 kWh.
One “Petroleum barrel” is a liquid measure equal to 42 U.S. Gallons (35 Imperial gallons or 159 liters).
About 7.2 barrels oil are equivalent to one tonne of oil (metric) = 42-45 GJ.
