2. Volume correction factor - Wikipedia

   en.wikipedia.org/wiki/Volume_Correction_Factor

   These methods are often more time-consuming than entering the values into a VCF calculator; however, due to the variance in methodology and computation of constants, the tables published by the American Petroleum Institute are preferred when dealing with the purchase and sale of crude oil and residual fuels.

3. Thermodynamic databases for pure substances - Wikipedia

   en.wikipedia.org/wiki/Thermodynamic_databases...

   The database provider must use recognized data analysis procedures to resolve differences between data obtained by different types of experiments. All thermodynamic data is a non-linear function of temperature (and pressure), but there is no universal equation format for expressing the various functions.

4. Oil and gas reserves and resource quantification - Wikipedia

   en.wikipedia.org/wiki/Oil_and_gas_reserves_and...

   The materials balance method for an oil or gas field uses an equation that relates the volume of oil, water and gas that has been produced from a reservoir and the change in reservoir pressure to calculate the remaining oil & gas. It assumes that, as fluids from the reservoir are produced, there will be a change in the reservoir pressure that ...

5. Atmospheric distillation of crude oil - Wikipedia

   en.wikipedia.org/wiki/Atmospheric_distillation...

   The hot crude oil is then passed into a distillation column that allows the separation of the crude oil into different fractions depending on the difference in volatility. The pressure at the top is maintained at 1.2–1.5 atm [ 2 ] so that the distillation can be carried out at close to atmospheric pressure, and therefore it is known as the ...

   TDT – thermal decay time log; TDTCP – TDT CPI log [clarification needed] TDT GR – TDT gamma ray casing collar locator log; TEA – triethanolamine; TEFC – totally enclosed fan-cooled; TEG – triethylene glycol; TEG – thermal electric generator; TELER – teledrift report; TEMP – temperature log; TETT – too early to tell

7. Crude oil stabilisation - Wikipedia

   en.wikipedia.org/wiki/Crude_oil_stabilisation

   Overhead gas from the stabilizer passes through a back pressure control valve that maintains the pressure in the stabilizer. [5] The stabilised crude oil, comprising pentane and higher hydrocarbons (C 5 +), is drawn from the base of the stabilizer and is cooled. This may be by heat exchange with the incoming live crude and by cooling water in a ...

8. K factor (crude oil refining) - Wikipedia

   en.wikipedia.org/wiki/K_factor_(crude_oil_refining)

   The K factor or characterization factor is defined from Rankine boiling temperature °R=1.8Tb[k] and relative to water density ρ at 60°F: . K(UOP) = / The K factor is a systematic way of classifying a crude oil according to its paraffinic, naphthenic, intermediate or aromatic nature. 12.5 or higher indicate a crude oil of predominantly paraffinic constituents, while 10 or lower indicate a ...

9. Crude oil assay - Wikipedia

   en.wikipedia.org/wiki/Crude_oil_assay

   No two crude oil types are identical and there are crucial differences in crude oil quality. 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 ...
