Is it possible to apply a bulk shift to a 3D survey in OpenDtect?

Yes, use the Reference Shift attribute. For more info on attributes, see https://www.dgbes.com/index.php/software/attributes-table 

Best regards,

Paul.

You can also use the Mistie Application attribute from the WMPlugins package to do it.  You will need to use the Survey|Manage|Mistie Correction menu item to get an editor to create a mistie correction database with an entry for the dataset. 3D data is described like "3D_<cube name>" where <cube name> is the dataset name, eg pstm.  The mistie correction database can include a phase rotation and amplitude scalar as well. If you have 2D and 3D data in the project there is also the Analysis|Mistie Analysis menu item to estimate misties and least squares corrections from the data itself.
