  2. 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.

  3. API gravity - Wikipedia

    en.wikipedia.org/wiki/API_gravity

    When converting oil density to specific gravity using the above definition, it is important to use the correct density of water, according to the standard conditions used when the measurement was made. The official density of water at 60 °F according to the 2008 edition of ASTM D1250 is 999.016 kg/m 3. [2] The 1980 value is 999.012 kg/m 3. [3]

  4. Barrel (unit) - Wikipedia

    US dry barrel: 7,056 cubic inches (115.6 litres; 3.3 US bushels) . Defined as length of stave 28 + 1 ⁄ 2 in (72 cm), diameter of head 17 + 1 ⁄ 8 in (43 cm), distance between heads 26 in (66 cm), circumference of bulge 64 in (160 cm) outside measurement; representing as nearly as possible 7,056 cubic inches; and the thickness of staves not greater than 4 ⁄ 10 in (10 mm) [2] (diameter ≈ ...

  5. Barrel of oil equivalent - Wikipedia

    en.wikipedia.org/wiki/Barrel_of_oil_equivalent

    Metric regions commonly use the tonne of oil equivalent (toe), or more often million toe (Mtoe). Since this is a measurement of mass, any conversion to barrels of oil equivalent depends on the density of the oil in question, as well as the energy content. Typically 1 tonne of oil has a volume of 1.08 to 1.19 cubic metres (6.8 to 7.5 bbl).

  6. Energy density - Wikipedia

    en.wikipedia.org/wiki/Energy_density

    A 1 inch tall uranium fuel pellet is equivalent to about 1 ton of coal, 120 gallons of crude oil, or 17,000 cubic feet of natural gas. [15] In light-water reactors , 1 kg of natural uranium – following a corresponding enrichment and used for power generation– is equivalent to the energy content of nearly 10,000 kg of mineral oil or 14,000 ...

  7. Perdido (oil platform) - Wikipedia

    en.wikipedia.org/wiki/Perdido_(oil_platform)

    Perdido (Spanish for lost) is the deepest floating oil platform in the world at a water depth of about 2,450 meters (8,040 feet) operated by the Shell Oil Company in the Gulf of Mexico. [ 1 ] The platform is located in the Perdido fold belt which is a rich discovery of crude oil and natural gas. The Perdido spar began production in 2010 and its ...

  8. Capillary length - Wikipedia

    en.wikipedia.org/wiki/Capillary_length

    If the temperature is 20 o then = 2.71mm. The capillary length or capillary constant is a length scaling factor that relates gravity and surface tension. It is a fundamental physical property that governs the behavior of menisci, and is found when body forces (gravity) and surface forces (Laplace pressure) are in equilibrium.

  9. Oil tanker - Wikipedia

    en.wikipedia.org/wiki/Oil_tanker

    In 2005, 2.42 billion metric tons of oil were shipped by tanker. [2] 76.7% of this was crude oil, and the rest consisted of refined petroleum products. [2] This amounted to 34.1% of all seaborne trade for the year. [2] Combining the amount carried with the distance it was carried, oil tankers moved 11,705 billion metric-ton-miles of oil in 2005 ...
