Editing facies classes

You can use the Edit Facies Classes form to:

  • Add a new facies class to your model that is not available in the upscaled well log property
  • Change the display color of newly added facies
  • Delete a facies class you added using this form
  • Review the presence of the facies classes per VOI
To edit the facies classes of a facies log (e.g. before it has been upscaled), scroll to the log under Well Data > All Logs, and use the log's context menu Properties > Edit Classes. See Discrete Property Class Editor .

To add a facies class

  1. Click the green plus icon ( ).
  2. A new facies class is added, with the name Facies<ID number>.
    3. Important   If you adjust the name or ID of the new facies, keep in mind that both the name and ID number of the facies class must be unique in the current table.
  3. If needed, you can adjust the color that is used to represent the facies in the 'Color' column.
  4. Click Apply to save the changes and keep the form open, or click OK to save the changes and close the form.

To delete a facies class

You can only delete facies classes which you added yourself (i.e. which were not automatically generated during upscaling).

  1. In the Edit Facies Classes table, select the facies class you want to delete.
  2. Click the delete icon ( ).
  3. The facies class is removed from both tables on the form.
    4. Important   When you delete a facies class after you have gone through the complete workflow, you need to reset the 'Facies Proportions' on the Trends and Proportions form and rerun the Run Model step in the workflow.
  4. Click Apply to save the changes and keep the form open, or click OK to save the changes and close the form.

Facies Class Per VOI table

The following facies classes are listed as columns on this table:

  • Already existing  The facies classes available in the upscaled well log.
  • Newly added  The facies classes you added using the Edit Facies Classes form.

Found in upscaled   Shows whether the facies class is available in the upscaled log or not. For review purposes only and cannot be edited.

Use in model  Only editable for newly added facies classes. Checked by default, uncheck this option to exclude a facies class from the model.

Important   To include your newly added facies class in your model, you still need to adjust the Facies Proportions on the Trends and Proportions form. On the Adjacent Facies tab/section adjust the proportion by selecting Manual Input to actually model the added facies. On the Vertical, lateral or 3D tab/section, select a vertical trend, and open the Edit Vertical Proportion Curve to adjust the proportions per k-layer.
