    en.wikipedia.org/wiki/Benchmark_(crude_oil)

    Using benchmarks makes referencing types of oil easier for sellers and buyers. There is always a spread between WTI, Brent and other blends due to the relative volatility (high API gravity is more valuable), sweetness/sourness (low sulfur is more valuable) and transportation cost. This is the price that controls world oil market price.

  3. Reid vapor pressure - Wikipedia

    en.wikipedia.org/wiki/Reid_vapor_pressure

    Reid vapor pressure (RVP) is a common measure of the volatility of gasoline and other petroleum products. [1] It is defined as the absolute vapor pressure exerted by the vapor of the liquid and any dissolved gases/moisture at 37.8 °C (100 °F) as determined by the test method ASTM-D-323, which was first developed in 1930 [2] and has been revised several times (the latest version is ASTM D323 ...

    The Illinois Basin has produced more than four billion barrels of petroleum. [6] Major oil production began in 1905, and from 1907 through 1912, the basin was the third-most oil productive area in the United States. Oil production peaked in 1908 at 34 million barrels per year, and declined steadily to 5 million barrels in 1933.

    en.wikipedia.org/wiki/Crude_oil_assay

    The results of crude oil assay testing provide extensive detailed hydrocarbon analysis data for refiners, oil traders and producers. Assay data help refineries determine if a crude oil feedstock is compatible for a particular petroleum refinery or if the crude oil could cause yield, quality, production, environmental and other problems.

    While HV measures how much the price of an asset has moved before, implied volatility reflects market expectations of future volatility. Both metrics offer pricing insights, but in different ways:

  8. Naphthenic oil - Wikipedia

    en.wikipedia.org/wiki/Naphthenic_oil

    For refineries, the interest has been primarily focused on the distribution between the distillation fractions: petrol, paraffin, gas oil, lubricant distillate, etc. Refiners look at the density of the crude oil – whether it is light, medium or heavy – or the sulfur content, i.e. whether the crude oil is “sweet” or “sour”.

  9. Volatility (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Volatility_(chemistry)

    Volatility can also describe the tendency of a vapor to condense into a liquid or solid; less volatile substances will more readily condense from a vapor than highly volatile ones. [1] Differences in volatility can be observed by comparing how fast substances within a group evaporate (or sublimate in the case of solids) when exposed to the ...
