About the Horizon Table Dialog Box

From the Map menu bar, select Horizon | View Horizon Table or press <p> on your keyboard.

• ID

In your map, ProductName will post all the horizons/faults with a selected ID check box. To post or to turn off a currently posted horizon, double-click the horizon's corresponding ID check box. To post multiple events to the map, select more than one horizon's ID check box.

• Posting to Seismic - By default, all the horizons and faults in your database are displayed on your seismic. To choose to have only a subset of these horizons/faults displayed on your seismic, select only the check boxes you want to display.
• Posting to Map - The attribute posted will depend on your setting for posting. If no posting setting has been made, time will be posted by default.

• Name

This column displays the available horizons and faults in your database. To change the name of a horizon or fault, double-click the name to make it editable. Then, type in the new name. ProductName automatically saves any changes you make.

• Click the Name header to sort the column.

• Color

In this column, you can select the horizon/fault colors for drawing on the seismic, horizon, and time slices. To change a color of an event, double-click on its color box to open the Choose Color For dialog box, and select a new color.

• Type

This column indicates if the event is a horizon or a fault.

• You cannot change an existing horizon to a fault or vice versa. If an event is incorrectly defined, you must select the event and then press <Delete> on your keyboard to remove the event. Then, click <New> to define a new horizon or fault.

• Event

This column displays the event type. Read more.

• +/-

This column displays the merge/replace setting, which controls whether auto, lateral, and volume picking will keep, or replace existing picks.

• Merge - When a horizon is set to Merge, auto and lateral picking keep the existing picks and merges them with the new picks. 3D volume picking incorporates existing picks into its guide line.
• Replace - When a horizon is set to Replace, auto and lateral picking disregard existing picks and replace them with new picks. 3D volume picking replaces existing picks.
• If ProductName is in auto, lateral, or volume picking mode, the Status bar in the upper left-hand corner of the Seismic window will display the merge/replace setting .
• The merge/replace setting does not apply to faults. 3D Volume Fault Interpolation always replaces existing fault markings.

You can change the merge/replace setting using either of the following methods:

• Click anywhere in the Seismic window to make it active and press <Alt> + <m> on your keyboard, or
• From the Edit Properties dialog box or the Post Time dialog box, double-click Merge or Replace (located under the +/- column) to change the setting.

• VolPick

Use this column to enable volume picking. Double-click the event's corresponding VolPick check box to turn on volume picking for that event.

• Slice(On)

Use this column to draw an event in the Map window on your horizon and time-slices. To do this, double-click to select that event's Slice(On) check box.

• Symbol

This column displays the symbol that represent the horizon/fault's intersections on the horizon and time-slices. To change the symbol, repeatedly double-click the current symbol to cycle through the list of possible symbols. Stop double-clicking once you arrive at the symbol you want to use.

• Seismic(On)

Use this column to draw an event on your seismic data. To do this, double-click to select that event's Seismic(On) check box.

• Summary 

Below the horizons and faults, you can view a summary of the number of horizons and faults enabled for volume picking and volume interpolation. You can volume pick more than one horizon, or interpolate more than one fault each time you open this dialog box. Since you could inadvertently overwrite horizon picks or fault markings from a previous operation, it is important to double check this summary.

• Sort by Avg Time

Use the buttons in this section to select how to sort your horizon or fault database. Click <Incr.> to sort your horizon or fault database by increasing time (shallow to deep), or <Desc.> to sort by decreasing time (deep to shallow).

• Volume Rename/Delete 

Right-click on a horizon or fault to open a shortcut menu where you can rename or delete that horizon or fualt. If you select the Apply to All check box first, ProductName will rename or delete all the horizons or faults you select. If you clear the Apply to All check box, ProductName enables you to rename, or delete horizons or faults for specific volumes.

• You can also rename, delete, or hide horizons from a specific volume by right-clicking on the horizon annotation on the side of your seismic section.
