B01.2 • Reservoir Properties
Let us now define the reservoir properties (petrophysics, KrPc, initial state). Click on
‘Properties’ in the ‘Simulation’ page to edit the ‘Reservoir – Properties’ dialog:
Change the reservoir type to ‘Layered’:
In the assignment table located below the
reservoir type, select the two lowest cells:
Click on to create a new property set called
‘Lower zone’:
Add vertical anisotropy to the petrophysics of this
property set by checking the ‘Vertical anisotropy’
box. Change k to 25 md, kv/kh to 0.1 and the
leakage to 0.01 – this last parameter describes
the layer-to-layer permeability reduction:
Edit the Default property set by selecting it in the
assignment grid: vertical anisotropy is also
checked here, as it is a global reservoir property.
However we may change the anisotropy ratio
itself locally: set it to 0.05, and change k to 100
md, Phi to 0.15, and the leakage factor to 0.01:
The reservoir petrophysics are now – quickly – defined. To finish, click on the ‘Initial State’
button to enter the reservoir initial fluid levels, and in the following dialog change the GOC
to 5940 ft, the WOC to 6065 ft and the reference initial pressure to 4000 psia:
