FIGURE 8.5 Dead oil viscosity for a low GOR oil compared with viscosity calculated from
different correlations. GOR, gas oil ratio.
FIGURE 8.6 Live oil viscosity for a low GOR oil compared with viscosity calculated from dif-
ferent correlations. GOR, gas oil ratio.
The main distinction, however, is that only undersaturated correlations are
usually necessary. Bubble-point pressure correlations can be used to ensure
that the predicted bubble point pressure is well below the reservoir pressures
that will be encountered during reservoir depletion.
Appendix A, Oil Correlations Formulae, shows a large number of
available oil PVT correlations. Appendix C, Oil Correlations Range of
