Note: If selecting Line detection method – Automatic, trace headers will be analyzed and the most likely line/inline and trace/crossline headers are selected. When the automatic method is selected, scanning is unavailable since the headers are undetermined until the SEGY file is read.

SEG-Y settings
Seismic bulk data storage – the seismic main folder
1. Insert ‘New seismic main folder’ 2. The Seismic main folder appears in the Input pane with a predefined hierarchy 3. Right click or use the Insert menu to add seismic survey folders

Objectives
Loading seismic data - Import parameters
4. Set Line detection method other than Automatic. Specify Inline/crossline number byte positions. For 2D lines, byte position for CDP and SP is changeable 5. It is possible to scan a specified number of traces to QC the parameter selection 6. In the Input Data Dialog window, select the desired color template and correct domain

Units must be set correct when importing data. There is no automatic unit conversion except when importing data. Since Petrel recognizes the import data just as numbers, i.e. depths, changing the units will not change the data itself
Loading seismic data - Import with preset parameters
1. Right click on a survey folder and use ‘Import (on selection)’ 2. Select the file, set ‘Files of type’ and click Open 3. Set corresponding data type (2D/3D), define vintage and Line detection method

Note: Messages related to import of seismic data is added to the Petrel messages log
Seismic vintages
1. Expand the Vintages folder found in the Seismic main folder 1
Setting project units
1. Open Project Settings from the Project menu
2. Go to the Uniቤተ መጻሕፍቲ ባይዱs tab. Change Units system to correct settings 3. Select the corresponding coordinate system from the Projection button

Note: If loading 2D seismic, 3D seismic in ZGY format or 3D seismic SEG-Y with preset parameters and selecting Line detection method – Automatic, Lateral geometry and Lateral translation/rotation cannot be changed. The remaining methods for loading 3D SEG-Y data enables redefining the geometrical extent of the seismic

Note: The seismic main folder contains by default a Vintage folder (to be explained later), Interp survey inclusion filters and an Interpretation folder with an active seismic horizon. Only one Seismic main folder can exist in a project.
2. The vintage names are given sequentially when importing data using Set default vintage
