IXSeg2Segy is a 32-bit Windows program designed to read SEG-1, SEG-2, SEG-Y, ASCII, CSV and other instrument manufacturer’s multi-channel seismic data formats and output the data as SEG-2, SEG-Y or ASCII files.

It also functions as a SEG-1 viewer, SEG-2 viewer and SEG-Y viewer.

IXSeg2Segy allows the user to process the data using integration, differentiation, DC level and linear trend removal, as well as both band-pass and F-K velocity filtering.

IXSeg2Segy allows the user to pick first breaks manually by positioning the mouse cursor at the break point on the trace and clicking the left mouse button. Automatic break picks can be made using four different methods. 

Breaks can be automatically interpreted in terms of a flat 2-layer earth. 

Normal Move-Out (NMO) curves can be superimposed on a shot to check the velocity and depth of an apparent reflector.

IXSeg2Segy allows the user to convert groups of files to SEG-2 or SEG-Y format and to export the first break picks to an ASCII file. Unregistered versions do not support these two features.

A SEG-Y file containing multiple records can be split into single record files. Multiple files with identical length records can be combined into a single SEG-Y file with multiple records or they can be merged to create a different set of files as described below.

Trace data can be viewed, printed, or exported as SEG-2, SEG-Y or ASCII  formats.

Formats Supported

Input
  • SEGY format - ASCII or EBCDIC header, LSB first or MSB first byte order
  • SEG2 format
  • User-Defined binary format
  • Non-compliant SEG-Y format
  • ABEM Mark 4 format
  • Bison Geopro-1 format

    • * Can be added on request from registered users. 

    DISPLAY
  • Traces can be displayed by trace number or trace position.
  • Traces can be plotted vertically or horizontally.
  • Variable area fill of positive trace is available.
  • Trace width and clip is user-specified.
  • Timing lines can be optionally drawn at major division or minor division boundaries.
  • Scaling can be by global max, trace max or each trace can be individually scaled by AGC using variable length.
    •

    PROCESSING
  • Integration, differentiation, DC level removal, linear trend removal.

    •
  • Traces can be flipped upside down.

    •
  • Band-pass filtering using interactive windows showing input traces, filtered traces, data spectrum w/filter spec and filter impulse response.

  • F-K Velocity filtering using interactive windows showing input traces, filtered traces, F-K spectrum w/filter wedges and numerical filter specification


  • Several files can be merged: N files with M traces each are merged to M files with N traces each. For example, merging several different shot files will create several common offset gathers.
  • XSeg2Segy also provides for file combining. With file combining, a number of input files are combined into a single SEG-Y file with multiple records. Each file to be combined must have the same number of traces and samples and the same sample rate as all other files being combined. If input files are SEG-Y format, they can each contain several records.
  • The records in a SEG-Y file can be concatenated. This is used in the case that the SEG-Y reel header is incorrectly specified as n records with1 trace per record instead of 1 record with n traces. Concatenation combines all of the traces in the SEG-Y file into a single record.

    OUTPUT
  • SEG-Y format - ASCII or EBCDIC header, LSB first or MSB first byte order
  • SEG-2 format
  • ASCII format
