values) and calculate the bubble point pressure, formation volume factor,
solution GOR, oil density and oil viscosity from correlations (use Glaso,
1980; Standing, 1947; Lasater, 1958 correlations). Plot the results of your
calculations to compare the values of PVT properties calculated from the
information in the three separator tests. Compare your calculated bubble
point pressure with the laboratory-measured bubble point pressure. Separator
test data is given in Table 6.2.
Table 6.3 gives the uncorrected (for separator conditions) PVT laboratory
measurements for all properties obtained from the CCE and DL experiments.
Dead oil viscosity is 0.824 cp at the reservoir temperature of 232 F. Single
stage flash of the fluid results in GOR of 3223 scf/STB.
