Fig. B01.6 • Edition of component properties
We will keep here all parameters to their default values and just click on ‘OK’ to get back to
the compositional PVT definition dialog. We can navigate through the various tabs to edit the
corresponding evaluated properties. Click finally on the ‘P. bubble’ tab:
Fig. B01.7 • Reference composition phase envelope
The table on the right hand side displays the bubble point pressure as a function of
temperature for the reference composition while the plot shows the complete phase envelope
composed of the bubble points (yellow), direct due points (green) and retrograde due points
(red) for the reference composition. Note for later use that by looking up at the plot, we see
that for a temperature of 350° F this composition gives a bubble point pressure of
approximately 1310 psia.
