(bboe, sometimes BOE) is a unit of energy
based on the approximate energy released by burning one barrel

. The US Internal Revenue Service
defines it as equal to 5.8 × 106 BTU
5.8 × 106 BTU59 °F equals 6.1178632 × 109 J or about 1.70 MWh.
A commonly used multiple of the bboe is the kilo barrel of oil equiavalent (kbboe or kBOE), which is 1,000 times larger.
The bboe 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.
A bboe is roughly 6000 cubic feet (170 cubic meters) of typical natural gas.
