3D Grid Zonation View

The 3D Grid Zonation View serves two functions for the 3D gridding workflow: to provide information related to your zonation and allow you to extend your hierarchy prior to grid creation. The view works hand-in-hand with the Edit Model form as the data that can be edited is made active by your selection in the view.

Accessing the 3D Grid Zonation View

The view is commonly opened as part of the 3D Gridding workflow in the 3D Grid strip. In this case, opening the Edit Model form also opens the view, and the two may be used together when working with the hierarchy. The view can be identified by the label just above the hierarchy, which reads "3D Grid Zonation View". Upon opening the zonation of the assigned 3D structural model is displayed.

Features of the 3D Grid Zonation View

The view differs from the similar Stratigraphic and Structure Zonation views in that there is additional functionality available for extending the hierarchy. You can add levels to the existing hierarchy, create zones within the new levels and sub-divide those zones into K-layers. However, even for new levels and zones, geological events cannot be assigned or modified at this stage, as assigning events can only be performed during the Stratigraphic Modeling workflow. The thickness of these zones is therefore not 'steered' by event data but conformable to, or proportional with (depending on your choice) the surface above or below.

Visual indicators in the view

The view provides information using visual indicators in the hierarchy itself. Top and base events can be identified easily as colored labels. Indicated in the label is also the type of event, surface or marker, indicated by an [S] and/or [M] following the event name. This allows you to quickly identify the data that will be used to constrain zones without having to check in the Edit Model form. Theoretically, most events have a surface representation [S] at this stage of the modeling process, since the 3D structural model has already been built in previous steps of the workflow. However, the application allows for building a 3D grid at a deeper stratigraphic level than the level used for the 3D structural model, in which case the [S] and/or [M] indication is helpful.

Another important visual indicator is the tooltip that appears when hovering over any zone in the hierarchy. This tooltip displays the zone name and the names of the constraining events in order to aid you when reviewing information for large and complex hierarchies. Because, in this case, the application will hide information that would otherwise clutter the display of such a complex hierarchy, the tooltip allows you to quickly view this basic information for every zone.

3D Grid Zonation view context menu

Depending on where the zone was created, you will have different context menu options available. For zones that were defined as part of the stratigraphical workflow (those with diagonal lines) three options are available:

Insert child zone above  Creates a child zone at the top of a deeper level.
Insert child zone below  Create a child zone in the base of a deeper level.
Split zone on deeper level  Creates child zones on a deeper level with a user-specified number of sub-zones.

For zones that were added in the 3D Grid Zonation view:

Rename zone  Allows you to rename the zone
Insert child zone above  Creates a new zone above your selection.
Insert child zone below  Create a a new zone below your selection.
Split zone  Splits the selected zone into a specified number of zones at the same level.
Split zone on deeper level  Creates child zones on a deeper level with a user-specified number of sub-zones.
Demote zone  Moves the selected zone to a deeper level.
Set color  Select a color for the zone. The child zones of the selected zone will have the same color but in a lighter shade.
Auto create colors  Select a predefined colorset from the context menu.
Delete zone  Deletes the selected zone (and its child zones).

3D Grid Zonation view toolbar

There is a toolbar at the top of the view to help you navigate, change the display and copy and save the view contents. The features in the toolbar at the top of the 3D Grid Zonation view allow you to change the vertical zoom level of the view, change the zone thickness display size and view basic info for each zone in the hierarchy.

Zoom  You can vertically zoom the view in two ways: by pressing Alt and scrolling to the desired zoom level, or by using the Zoom text box to select a level. With the zoom box you can type in a zoom value or select from the drop-down list. If you select a zone in the view and use Alt + scroll to zoom, the selected zone will stay focused in the view.

 Reset zoom  Clear all zoom changes, resetting the zoom level back to 100%.

Zone thickness display  Set the display of the zones on the lowest hierarchical level to relative (default setting) or equal. In equal thickness mode all zones are equally thick on the lowest hierarchical level present in the view. See the section below for more details on this setting.

Probe  (shortcut key: Ctrl+I) Activates the Probe. When you hover over a zone the Zone name and top and bottom events are displayed.
