Lateral Picking Mode

The lateral picking mode is an automatic picking mode. Click on a starting point and lateral pick will continue picking until it can find no suitable pick within the picking gate. Lateral picking is controlled by the event type and the merge/replace setting for a horizon.

Using the Lateral Picking Mode

If the words Lateral Pick do not appear on the Current Pick Mode button located on the Horizon Picking toolbar, you need to toggle off the current picking mode.

Click on the <Current Pick Mode> button and select Lateral Pick from the drop down list (or press <l> on your keyboard).

The words Lateral Pick will now be displayed on this button.

Lateral pick in both directions – Click on the event you wish to pick. Lateral pick will continue placing picks on the event type in both directions until it can find no acceptable event type to pick or until it reaches the end of the line.
Lateral pick in one direction – Click on an event and, without lifting the mouse button, drag your cursor across a few traces in the direction you wish to pick. When you release the mouse button, lateral picking will continue in that direction until no acceptable pick can be found or until the end of the line is reached.
Adding lateral picks in horizons set for merge - Horizons set for merge will not allow lateral picking to replace existing picks. When adding picks to a partially picked horizon which has been set for merge, start your lateral pick by clicking a trace or two off the end of the existing pick segment.

Press <l> on your keyboard to toggle off lateral mode and return to auto picking mode.
