Oil Viscosity
Table 6.8 shows the oil viscosity calculated from the three correlations.
Fig. 6.16 shows the computed oil viscosity using the different corrections
(using total solution GOR of separator test 1 as input) compared with the
laboratory-measured oil viscosity.
The figure shows low values of oil viscosity, which are expected for
volatile oil fluids.
