From Wikipedia, the free encyclopedia

The barrel of oil equivalent (BOE) is a unit of energy based on the approximate energy released by burning one barrel (42 US gallons or 158.9873 litres) of crude oil. The US Internal Revenue Service defines it as equal to 5.8 × 106 BTU.[1]

5.8 × 106 BTU59 °F equals 6.1178632 × 109 J or about 6.1 GJ (HHV).

Value should be about 5.7 GJ (LHV) see Ton of Oil Equivalent~

A BOE is roughly 6,000 cubic feet (170 cubic meters) of typical natural gas.[2]

A commonly used multiple of the BOE is the kilo barrel of oil equivalent (kboe or kBOE), which is 1,000 times larger.

Other common multiples are the BBOe, (also BBOE), or billion barrel of oil equivalent, representing 109 barrels of oil, used to measure petroleum reserves,[3] and million barrels per day, MMbd (or MMBD), used to measure daily production and consumption.[4] Also used is the Mtoe, or Millions of tonnes of oil equivalent, a metric measurement equivalent to approximately 0.006841 BBOE.[5]

The BOE is used by oil and gas companies in their financial statements as a way of combining oil and natural gas reserves and production into a single measure.
