Oil Formation Volume Factor

Standing (1947)

N.B. At pressures less than bubble point pressure, the Standing (1947) correlations are used to calculate the solution gas-oil ratio and the saturated oil formation volume factor. 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 formation volume factor.
