Enable Volume Picking

WinPICS will display on your basemap all the horizons/faults with a selected ID check box. Double-click to select a check box. To post multiple events to the map, select more than one 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.

Displays the available horizons and faults in your database. To change the name of an event, double-click the name to make it editable, and type the new name.

• Click Name to sort the column.

You can select the horizon/fault colors for drawing on the seismic and horizon and time slices. To change a color, double-click on a color box to open a Choose Color For dialog box, and select a new color.

Displays 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.

Displays the event type. Read more.

Display 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, merging them with the new picks, and 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, replacing them with new picks, and 3D volume picking replaces existing picks.
• If WinPICS 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.

Changing the Merge/Replace Setting

You can change this setting using either of the following methods:

• From within the Seismic window, press <Alt> + <m> on your keyboard, or
• From the Current Horizon/Fault dialog box or the Post Time dialog box, double-click Merge or Replace (located under the +/- column) to change the setting.

To enable volume picking for an event, double-click to select that event's check box.

To draw an event on your seismic data, double-click to select that event's check box.

To draw an event in the Map window on your horizon and time-slices, double-click to select that event's check box.

Displays the symbol that represent the horizon/fault's intersections on the horizon and time-slices. To change the symbol, continually 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.

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

Click <Incr> to sort your horizon/fault database by increasing time (shallow to deep) or <Desc> to sort by decreasing time (deep to shallow).

Right-click on a horizon/fault to open a shortcut menu where you can rename or delete it. If you select the Apply to All box first, WinPICS will rename or delete all the horizons/faults you select. If you clear the Apply to All box, WinPICS enables you to rename or delete horizons/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.
