Importing Horizons from one seismic project to another If you open the new auger_4d project, you won't be able to see the horizons that you created in the aug_psiv project. To fix that, you can export/import horizons so that you can see them in both projects. One thing to note - The changes will not show dynamically. In other words, if you export a horizon from aug_psiv and import it into auger_4d, if you then change it in aug_psiv, those changes WILL NOT show in the auger_4d project. You'll have to re-export and re-import. Here are instructions on exporting/importing horizons from one 3-D project to another: In OpenWorks, Data -> Management -> Seismic Project Manager In Seismic Project Manager, Horizons -> HIE Open aug_psiv project, File -> Export horizon Use the default format and name your output file (ie. yellow_horizon_export) Pick the horizon that you want to export (CWB_Yellow_Top) Click the "Export" button, this may take a few minutes to run In your Landmark Linux terminal, copy the output file that you just created in /pa/aug_psiv and put it in /pa/auger_4d: cd /pa/aug_psiv cp yellow_horizon_export ../auger_4d/. cd ../auger_4d ls -lrt to see if the output file is in the correct directory Back in HIE: File -> Import Pick your output file (yellow_horizon_export) Under horizons, pick "List" and "Create", make sure to specify in the name of your new horizon that it is an imported horizon, so name it something like CWB_Yellow_Import You should then be able to view your new horizon in the auger_4d project.
