Assign data
After creating the permeability property model, the next step is assigning data to your model (model > Permeability > Permeability Property Modeling > Assign Data).
To assign data to a permeability property model
- On the Assign Data form, select the permeability property model from the Property model drop-down list.
- In the Assign Data section of the form:
- Function model Select the permeability function model which will be used to populate the 3D grid.
- Target grid Select the 3D grid you want to populate with permeability properties. This will also filter out the options you see in the Grid Properties drop-down lists below.
- In the Grid Properties section of the form, select the properties you want to assign from the drop-down lists:
- Assign a Facies grid property if you have defined a permeability function per facies class in the permeability function model.
- Assign a Porosity and/or an Additional grid property if you have used these properties in the assigned permeability function model.
- Model ( Facies
, rock property 
) If a grid property is created with a modeling workflow, its model will be available in the drop-down list. Select a model to use its associated grid property. - Grid Property (
) If a grid property is created without a modeling workflow, it will be available in the drop-down list. For example, you may have created a property with the Property Calculator. - Click Apply to assign data to your model and keep the form open, or click OK to assign data and proceed to the Run Model form.
Important
If there is a mismatch between the facies classes of the log assigned to the function model and the facies classes of the grid property assigned at this step, you will receive an error message as a pop-up window when you run your property model at the end of the workflow.
Important
The grid cells with undefined facies, porosity or additional property values will also have undefined permeability values.
The drop-down lists for grid properties are populated with models and grid properties:
Uncertainty If you want to perform a probabilistic volumetric calculation with the Study strip (Study > Volumetrics), you must assign models which are created with their related modeling workflows.
If you have assigned a model, make sure that the model is run and its grid property is available. Otherwise, you will receive an error message as a pop-up window when you run your property model at the end of the workflow.
