The ZGY files created by the live-link manager during the realization process are created in the Petrel default seismic files directory. The default seismic files directory is set using the Seismic tab of the Petrel System settings dialog. The System settings dialog is opened using the System settings... option in the Petrel File menu.
Click on the Create external ZGY and SEGY files by default option to enable the Default directory selection option. Select the directory you want the ZGY files to be created in when using the live-link manager. Note, the directory will also be used to store SEGY files that are created when importing 2D seismic data using the Petrel adapter. The directory will also be used when realizing seismic data that was imported using Petrel's native seismic import features.
The default directory setting is used for all Petrel projects.
