In thermodynamics, the Volume Correction Factor (VCF), also known as Correction for the effect of Temperature on Liquid (CTL), is a standardized computed factor used to correct for the thermal expansion of fluids, primarily, liquid hydrocarbons at various temperatures and densities. [1]
MF, Meter Factor, adjust to actual volume, this factor is determined by probing CTL is a volume correction factor for the effects of temperature on liquid [32] SF, Shrinkage Factor, adjusts for changes in pressure temperature and composition, for instance shrinkage of fluid occurs when pressure drops and constituents change to gas phase
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.
Oil conversion factor from m³ to bbl (or stb) is 6.28981100; Gas conversion factor from standard m³ to scf is 35.314666721; Note that the m³ gas conversion factor takes into account a difference in the standard temperature base for measurement of gas volumes in metric and imperial units.
The oil in place is calculated as the product of the volume of porous oil-bearing rock, the porosity of the rock, and its saturation. [1] Correction factors have to be applied for the difference between the volume of the same mass of oil in the reservoir to its volume when brought to the surface, which is caused by the different physical ...
where p is the pressure of the gas, T is its temperature, and is its molar volume, all measured independently of one another. In the case of an ideal gas, the compressibility factor Z is equal to unity, and the familiar ideal gas law is recovered: =
The volume of gas that an oil and gas separator will remove from crude oil is dependent on (1) physical and chemical characteristics of the crude, (2) operating pressure, (3) operating temperature, (4) rate of throughput, (5) size and configuration of the separator, and (6) other factors.
The temperature and pressure correction factors are and , so corr = / For speed the corrected value is N {\displaystyle N} corr = {\displaystyle =} N / θ {\displaystyle N/{\sqrt {\theta }}} Example : [ 17 ] An engine is running at 100% speed and 107 lb of air is entering the compressor every second, and the day conditions are 14.5 psia and 30 ...
