Data Load Wizard

The Data Load Wizard allows you to load 2D and 3D SEG-Y files.

Select the Data Geometry as either 2D Data or 3D Data.
Specify the Input Files:
- When Loading a 3D use this dialog to specify individual or multiple files for load.
- When Loading 2D use this dialog to specify individual or multiple files for load.
Press the button on the Data Format page to read the binary header information contained in the *.sgy file.
Scan the traces in the file on the Data Scaling page to determine if a Statistics Window needs to be set. A Statistics Window will affect how the data appears in the Seismic Viewer, but will not change the data values.
Press the button to view the file in the SEG-Y Viewer.
- For a 3D you will identify and define the Line Sequence Number (Inline), Trace Sequence Number (Crossline), Coordinate X and Coordinate Y for the file.
- For 2D you will identify and define the CDP, Shot Sequence Number, Coordinate X and Coordinate Y for the file.
When Defining Keywords you must first identify the word, graph it to ensure consistency through the file, then save it as a keyword .
On the Load Parameters page:
- For a 3D enter a Line Name, Display Type, Process ID and a File Description for the 3D.
- For 2D enter a default display type, process ID and a file description which will be used for all the files in the load.
Use the Individual File Parameters page to change the Line Names and Display types for all 2D data. You may also limit the range of data to be loaded by typing in the Start Trace and End Trace. This dialog does not appear when loading 3D data.
On the Additional Options page you may use a previously defined polygon to limit the trace range of data to be loaded. If the data must be projected to lie in a different Coordinate System you must define both the Source and Destination systems.
Select the Output Directory for your loaded files.
Press the button complete the load.

Note: Files are converted into a SeisWare specific form of SEG-Y during the load process. If your files are already in SeisWare or SeisX format you can just attach them to the project using the Attach Seismic Files application.

Data Loading Options

Data Geometry: Specify the geometry of data to load. You must load 2D and 3D data separately because they require different input parameters.

2D Data: Import 2D seismic files into the current project.

3D Data: Import a single 3D survey into the current project. 3D data needs to be imported one survey at a time.

Data Source: Specify the input source for the data.

SCSI Tape: Read the data from any SCSI tape device attached to your computer.

If loading 3D data from tape, click here.

If loading 2D data from tape, click here.

File: Read the data from raw SEG-Y files. These files can be located on a local hard drive, remote disk, or a local CD or DVD drive.

Tape Options

Tape Device: Specify the number of the tape device attached to your computer. This will normally be 0 unless you have more than one tape drive attached to you machine.

Output Directory: Specify where to write the imported SEG-Y files. The Output Directory defaults to the data directory of the current project. You can specify an alternate directory by selecting a location with the "..." button.

Rewind Tape: Rewind the tape that is currently in the drive. You may need to do this if the data load fails at some point.

Eject Tape: A quick way to eject the tape from the tape drive.

Scan Tape: Scan the tape to determine what it contains. This is useful when you receive a tape and are not sure of the number of files on the tape, or what exactly the tape contains. The scan will provide a listing of the number of files on the tape, the format they are in, their time interval, the number of samples per trace and the number of traces in each file.

Dump Tape: Dump the entire tape to disk. This can often speed the load process. Data can be loaded much more quickly from disk than from tape, especially if you need to scan files multiple times to perform scaling operations. Files will be written to the Output Directory and named sequentially (i.e. File0001.sgy, File0002.sgy ...).to scan files multiple times to perform scaling operations. Files will be written to the Output Directory and named sequentially (i.e. File0001.sgy, File0002.sgy ...).
