B03.2 • Defining the Initial State
Remain in the ‘Reservoir- Properties’ dialog and select the ‘Default’ property set.
Click on the initial state icon . As the context is single-phase, the definition of the initial
state is quite simple:
Fig. B03.2 • Initial state dialog
Set the reference pressure to 5000 psia at reference depth 8000 feet, and accept by clicking
on OK.
B03.3 • Defining the Geothermal gradient
Remain in the ‘Reservoir- Properties’ dialog and click on the geothermal gradient icon .
By default, a constant gradient is required, with a reference temperature at reference depth:

However, a more complex profile may be entered, in order to account for a varying gradient.
