Figure 3.8 shows the measured density of Louisiana sweet crude (LSC) oil
comparing the dead oil liquid to the liquid saturated with methane and includes
modeled data using the Peng-Robinson EOS and scaled to the data given in Fig. 3.6
(Gros et al. 2016).

Fig. 3.6 Measured solubility of methane in Louisiana sweet crude oil at 0–16 MPa gauge pressures. Filled symbols are measurements conducted in the laboratory according to method 1 and
method 2 described in Sect. 3.2.2, whereas the solid lines are predicted values using the PengRobinson equation of state with volume translation, after tuning
