8. Output Oil Recovery Efficiency

In Keyword Editor > Summary Section, add the following keyword:

FOE: (OIP(Initial) – OIP(now)) / OIP(initial)

After running the case, you can view the result in charting window.

9. Create Rock Quality Index property

The Rock Quality Index (RQI) is the parameter defined to characterize the rock quality based on the relation between

permeability and porosity.

To create the property in Petrel,

Open 3D Property Calculator.




45

Type in RQI formula where RQI = 0.0314 (Permeability/Porosity)^0.5. Attach template as General and click

Enter.

A new property is created under the Model pane.




46

10. Reservoir Opportunity Index calculation

In Results pane, Right click on Simulation grid results, and select Calculator.

Type the following expression on the calculator and click Parse expression.

ROI= Pow(Pressure*0.0314*Sqrt(Perm/Poro)*Porv*(Soil-Sor),0.3)

For Variable ROI, Select type as Grid property and Source 3D Grid. In Property column, Create New property and

select template as Region from Discrete property template folders.




47

Fill in the rest of the column and click Run. New property ROI is created under the Properties folder in Models pane.
