Configure a 2D SEG-Y File

The SEG-Y Config options allow you to set the configuration of a 2D SEG-Y file before processing.

  • Use the TraceViewer to examine the trace headers and select the appropriate byte-offset and data format to use for many of the configuration options below.

    • To Configure a 2D SEG-Y File

    1. Under SEG-Y Disk Format, select the Header Encoding (EBCDIC or ASCII)) from the drop-down list.

    2. Select the Byte Ordering (Big or Little Endian) from the drop-down list.

    3. Select the Data Format (1-, 2-, or 4-byte integer, 4-byte IBM or 4-byte IEEE floating point) from the drop-down list.

    4. Enter the Samples per Trace.

    5. Under Trace Order, select Sequentially or By Field Value. If using Field Value, enter the values and click Apply.

    6. Under Trace Masking, select No Trace Mask or Trace Mask. If selecting Trace Mask enter the values.

    7. Under Shot Point, select the trace header to be used as the source of the shot point numbers and click Apply.

    8. Under Navigation, choose the source of the trace coordinates, or elect to display the traces sequentially with no coordinates or distances used – the data will not be projected.

    9. Under Vertical units, set the vertical interval and units.
