correlation applicability range from Appendix C, Oil Correlations Range of
Applicability, for oil formation volume factor shows that the data of Fluid 3
is within the data range used to develop the correlation. However, the corre-
lation overestimates the formation volume factor, most likely due to the
biases of the correlation to lighter oil data. Many other correlations predict
an oil formation volume factor less than 1.0 rbbl/STB for low GOR oils.
These values should be rejected.
