1. Select the option Use the zones of existing zonation in the upper left corner of the window.

2. Choose the Set of zones you wish to edit.

Creating a New Set of Zones

There are four possible actions when working with zones:

Add Adds a zone when you enter the zone parameters (name, color and description) in the left side of the window and click Add.

The Graphical zone editor is a layout that looks like a multi-well (MW) LogView. To differentiate them, the background colors of the layouts are different - grey in the LogView and yellow in the Graphical zone editor.

Many LogView features are available in the Graphical zone editor.

To populate the plot, drag-and-drop variables from the Project browser.

If you selected the option Use the zones of existing zonation in the Zone parameters editor, the Graphical zone editor sets this zonation dataset as the current zonation dataset. This means that if you populate the layout, the tops of zones are dis-played automatically.

You can edit the zone tops by adding, deleting, moving or changing them.

NOTE: The bottoms are managed as the tops of the zones and are defined with the name '-9999.'

Creating a Layout

1. Click in the Zone parameter editor

window, an empty layout displays.

2. Drag-and-drop variables you need for the zonation creation into the layout. In the figure, Gamma ray and Neutron-Density curves are created for two wells.

Add a top in a well Left-click into any well track.

Add a top in multi-wells Press Shift + left-click into any well track.

Delete a top of a well Place the cursor on the top you want to delete and press the Delete key. The cursor changes its appearance.

Delete all the tops of a zone in single or multi-well

Place the cursor on the top of any zone you want to delete and press Shift + Delete. The cursor changes its appear-ance.

Move a top in a well Place the cursor on the top you wish to move and move it up or down. The cur-sor changes its appearance.

Saving Zonations

After you finish picking zonations, you may save them in any of these ways:

Save the zones into the database.

Save the zones into a temporary dataset that can be saved later.

Save the zones into the database, and open a log view showing the zonation.
