Transfer Horizons
The Transfer Horizons dialog allows you to transfer horizons from one line to another. This is particularly useful when you have 2D lines that overlap a 3D volume or two 3D volumes that overlap. The Transfer Horizons application will move horizon picks from one line to another, placing the pick on the closest trace (within the search radius) the other line.
How do I transfer a horizon to another seismic file?
-
Select the Source Lines by highlighting them in the Seismic Lines box and using the selection arrows to move them into the Source Lines box.
-
Select the Destination Lines by highlighting them in the Seismic Lines box and using the selection arrows to move them into the Destination Lines box.
-
Select the Horizons that you want transferred.
-
(Optional) Increase or decrease the Search Radius.
-
Set the Fill Mode.
-
(Optional) Specify any polygons you want to use to limit the geographical extents of the transfer operation.

General Information
Seismic Lines
Available Seismic Lines
Use this list to select the Source
and Destination lines for
the horizon transfer.
Left click to select a seismic line, left click while
pressing the Ctrl key on your
keyboard to select multiple seismic lines, or select a group of lines
from the Basemap.
To help you make your seismic line selections, you can sort any column
by left clicking
on the column header, you can apply a filter (
), or you can type a search string
into the search
bar to limit the list using Name
or Ownerinformation.
For additional selection and navigation options right click on the
Seismic Lines fileslist to access
the shortcut
menu.
Source
The list of seismic lines that you want source picks to be transferred from. The seismic lines can be moved back to the original list using the selection arrows.
Destination
The list of seismic lines that you want picks transferred to. The
seismic lines can be moved back to the Available list using the selection arrows.
Horizons
Select the horizons that you want to transfer. Left click to select a
horizon, or left click and press the Ctrl
key on your
keyboard to select multiple horizons. To help you make your horizon
selections, you can sort any of the columns by left
clicking on the column header, you can apply a filter (),
or you can type a search string into the search
bar to limit the list based on Name,
Type,or Ownerinformation.
For additional selection options right click on the Horizons fileslist to access
the shortcut
menu.
Transfer Properties
This is a list of parameters controlling how horizons are
transferred.
Search Radius: This controls how far to search for a pick to transfer to the destination line. The search radius is specified in the surface units of the project (either meters or feet). If there is a source pick within this distance, the destination pick will receive a value. Regardless of what this parameter is set to, the closest source pick will always be used for the destination horizon.
Fill Mode: Determine how to transfer picks to the destination.
Fill gaps only:This will only transfer horizons to the destination lines where a pick does not already exist. If a horizon value already exists in the destination it will not be overwritten.
Overwrite original picks:This will transfer a pick to the destination horizon even if there is already a horizon value for that trace, as long as it is within the Search Radius.
Polygons
Polygons:
Open the Select Polygons
dialog to select inclusion or exclusion polygons to define the
limits of the horizon transfer.
