  2. 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).

  3. Gas/oil ratio - Wikipedia

    en.wikipedia.org/wiki/Gas/oil_ratio

    Definition of formation volume factor Bo and gas/oil ratio Rs for oil. When oil is produced to surface temperature and pressure it is usual for some natural gas to come out of solution. 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.

    To get the answer, you multiply 14215469 by 5, so that 71077345 appears, turn the calculator upside down, and on 7-segment displays it appears as "ShEll OIl". Here's an apparent reference which shows up in Google (I haven't seen the article): "The Electronic Pocket Calculator: Joke 1:" by Lois A. Monteiro Western Folklore , Vol. 35, No. 1 (Jan ...

  5. Mud weight - Wikipedia

    en.wikipedia.org/wiki/Mud_weight

    In the oil industry, mud weight is the density of the drilling fluid and is normally measured in pounds per gallon (lb/gal) (ppg) or pound cubic feet (pcf) . [1] In the field it is measured using a mud scale or mud balance. Mud can weigh up to 22 or 23 ppg. A gallon of water typically weighs 8.33 pounds (or 7.48 ppg).

  6. Nameplate capacity - Wikipedia

    en.wikipedia.org/wiki/Nameplate_capacity

    Nameplate capacity, also known as the rated capacity, nominal capacity, installed capacity, maximum effect or gross capacity, [1] is the intended full-load sustained output of a facility such as a power station, [2] [3] electric generator, a chemical plant, [4] fuel plant, mine, [5] metal refinery, [6] and many others.

  7. Cetane index - Wikipedia

    en.wikipedia.org/wiki/Cetane_index

    Cetane index calculations can not account for cetane improver additives and therefore do not measure total cetane number for additized diesel fuels. Diesel engine operation is primarily related to the actual cetane number, and the cetane index is simply an estimation of the base (unadditized) cetane number.

  8. Butylated hydroxytoluene - Wikipedia

    en.wikipedia.org/wiki/Butylated_hydroxytoluene

    Butylated hydroxytoluene (BHT), also known as dibutylhydroxytoluene, is a lipophilic organic compound, chemically a derivative of phenol, that is useful for its antioxidant properties. [7]

  9. Field capacity - Wikipedia

    en.wikipedia.org/wiki/Field_capacity

    A relatively low rate of change indicates when macropore drainage ceases, which is called Field Capacity; it is also termed drained upper limit (DUL). Lorenzo A. Richards and Weaver [5] found that water content held by soil at a potential of −33 kPa (or −0.33 bar) correlate closely with field capacity (−10 kPa for sandy soils).
