Free Online PVT Calculator

Calculate the properties of petroleum reservoir fluids with a reliable, simple calculator.

Oil Density

Vazquez-Beggs (1980)

N.B. At pressures less than bubble point pressure, the Vazquez-Beggs (1980) correlations for the solution gas-oil ratio and the saturated oil formation volume factor are used to calculate the saturated oil density. At pressures greater than bubble point pressure, the Vazquez-Beggs (1980) correlation for the under-saturated oil compressibility is used to calculate the under-saturated oil density.
