Saphir Guided Session #6
A01 • Requirements
There are no special requirements for this guided session as we will use the test design facility
of Saphir.
The objective of this guided session is to illustrate some of the Saphir multiphase abilities.
You will be led through some of the Saphir dialogs and screens to enable the simulation of the
pressure response of a multiphase producer (oil and water) coupled with a water injector
(into oil).
The evolution of the fluid saturations will also be studied.
B01 • Initialization
Run Saphir and start a new project. Keep the well and reservoir characteristics at the default
values and specify the reference phase as oil, and in the 'available rates', add water. Specify
the starting analysis to be ‘NonLinear’; this will invoke the non linear multiphase simulator.
See Figure B01.1.
Fig. B01.1 • Initialization
The next screen is the document or project specific PVT dialog. Automatically 'Dead' oil is
selected with water. Leave the default PVT characteristics.
Accept the next PVT screen and change
Sw to
0.2
in the final PVT dialog. Adjust the value of
So to 0.8. The saturations entered here are only used for a constant system compressibility
calculation. You will later specify the 'Analysis' specific PVT and define initial saturations for
model generation and simulation. The next screen shows the PVT characteristics calculated for
the reference phase.
