  2. Barrel of oil equivalent - Wikipedia

    en.wikipedia.org/wiki/Barrel_of_oil_equivalent

    The barrel of oil equivalent (BOE) is a unit of energy based on the approximate energy released by burning one barrel (42 US gallons, 35 imp gal or about 159 litres) of crude oil. 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 ...

  3. Barrel (unit) - Wikipedia

    en.wikipedia.org/wiki/Barrel_(unit)

    Barrel (unit) Ale casks at a brewery in the UK. These are firkins, each holding 9 imperial gallons (41 L) or a quarter of a UK beer barrel. A barrel is one of several units of volume applied in various contexts; there are dry barrels, fluid barrels (such as the U.K. beer barrel and U.S. beer barrel), oil barrels, and so forth.

  4. Tonne of oil equivalent - Wikipedia

    en.wikipedia.org/wiki/Tonne_of_oil_equivalent

    The tonne of oil equivalent (toe) is a unit of energy defined as the amount of energy released by burning one tonne of crude oil. It is approximately 42 gigajoules or 11.630 megawatt-hours, although as different crude oils have different calorific values, the exact value is defined by convention; several slightly different definitions exist.

    Oil conversion factor from m³ to bbl (or stb) is 6.28981100; Gas conversion factor from standard m³ to scf is 35.314666721; Note that the m³ gas conversion factor takes into account a difference in the standard temperature base for measurement of gas volumes in metric and imperial units.

  6. Gas/oil ratio - Wikipedia

    en.wikipedia.org/wiki/Gas/oil_ratio

    The gas/oil ratio (GOR) is the ratio of the volume of gas ("scf") that comes out of solution to the volume of oil — at standard conditions. In reservoir simulation gas/oil ratio is usually abbreviated . A point to check is whether the volume of oil is measured before or after the gas comes out of solution, since the remaining oil volume will ...

    Fluid catalytic cracking. A typical fluid catalytic cracking unit in a petroleum refinery. Fluid catalytic cracking (FCC) is the conversion process used in petroleum refineries to convert the high-boiling point, high-molecular weight hydrocarbon fractions of petroleum (crude oils) into gasoline, alkene gases, and other petroleum products.
