Then, use the light grey line in the Crude oil volume correction figure At 50☌ the correction factor is 0.965. In the Density vs temperature figure(☌), you se that the light grey line represent this crude oil. ![]() You have 100 liters of a light crude oil with a density of 761 kg/m 3 at 50☌. ![]() To be sure you have used the correct figure for correction factors, the easy rule is that the volume increases with increasing temperature. Or, if you know the base volume and density, you can use the volume correction factor to calculate the volume at another temperature. Volume correction factors can be used to calculate the volume of a crude at base temperature (15☌/59☏) if you know the density and volume at another temperature. See also similar correlations for lubricating oil, fuel oils and jet fuel. If you have the crude density given in ☊PI, use the API-to-gravity converter. If the temperature changes, the density of the crude oil changes along the colored line.Įxamples of the use of the figures are given below the figures. ![]() Each colored line represents a crude oil with a given density at a given temperature. ![]() Correlations for crude oil density and temperature are found by use of tools based on ASTM D 1250-04 and IP 200/04 (API Manual of Petroleum Measurement Standards, Chapter 11- physical properties Data, Section 1:Temperature and pressure volume correction factors for generalised crude oils, refined products and lubricating oils).
