PVT parameters:
B and µ can be handled different ways:
 Constant at P avg.
 With a user entered pressure (manual pressure).
 Adaptative pressure. In this case, the IPR model calculates the sandface pressure Psf
with B and µ at P = (Pavg + Psf) / 2, starting at B and µ at Pavg. This method involves
an iterative process until convergence is obtained. Let Adaptative pressure by default.
When choices are validated, the IPR plot is created. It displays the sandface pressure, Psf
(from the IPR model) and the wellbore pressure, Pwf (from the completion model). If there is
no completion model defined, the IPR plot displays only the flowing pressure from the IPR
model.
