Import 3D seismic
Scan file
The resulting data set's name in the project is either based on the file name or byte positions in the EBCDIC header. To set EBCDIC header byte positions simply highlight the section you want as data set name. The label between the comboboxes always shows current nameLoading 3D seismic can be a time consuming job, and it is very important that the import settings are correct before starting (to avoid having to do the job again). Therefore, 3D import is usually performed by first setting the import settings, and then performing a scan on the very first inlines only. This is achieved by leaving the Min/Value Inline setting at From file, but setting the Max setting to 10 lines higher than the first inline. This means you have to know the start value of the Inline. You should be able to find this in the Trace header or the EBCIDIC header.
Follow the Scanfile guide explained for 2D seismic as it is almost identical to 3D seismic.
