The physical property density is the ratio between mass and volume.
The density of crude oil can be determined from :
- Specific gravity of the crude oil
- Solution gas gravity
- Solution gas-oil ratio
- Oil formation volume factor (FVF). [1]
Under any condition, density will be defined by
....................(1)
Stated more rigorously with PVT properties, this relationship becomes
....................(2)
This is valid for all pressure and temperature conditions for which the pressure-volume-temperature (PVT) properties are determined. As expressed, this equation provides density with the units of lbm/ft3.
