 Free SEG-Y File Editors/Viewers/Converters:

GSEGYView is a viewer for seismic data in SEG-Y format, its modifications, and many other related formats aimed to store either petroleum exploration data or seismology data. GSEGYView features graphics hardware acceleration via OpenGL for seismic data rendering, wiggle, variable area and variable density seismic traces representation, two-level sorting of seismic traces by arbitratry keys in trace headers, multiple windows for multiple files with separate display parameters, easy seismic section navigation and zoom with mouse wheel support, and more.

The software presented in this report, referred to as SEGY to ASCII (SAC), converts seismic data written in SEGY format (Barry et al., 1975) to an ASCII data file, and then creates a postscript file of the seismic data using a general plotting package (GMT, Wessel and Smith, 1995). The resulting postscript file may be plotted by any standard postscript plotting program.

A set of about 170 functions (plus support functions called by them) for analysis and display of exploration-seismic data and well logs. These functions read and write seismic data in standard SEG-Y format, read and write well logs in LAS-format 2.0 (also read LAS-format 3.0), and perform many of the manipulations usually performed on these data types. They use standardized structures to represent seismic data and well data and thus allow simple concatenation of function calls.

The Volume Browser displays scalar 3-D datasets, essentially functions of three variables, by means of static and animated slices (the latter can be saved as movies), contour slices, and iso-surfaces.

  • KWeb (by Exprodat)

“…you can view well and seismic data stored in KINGDOM projects without having to start the KINGDOM application”

“Whereoil for Kingdom SMT allows users to search through the metadata in all of your Kingdom SMT projects. Selected datatypes are additionally spatialized, and spatial data is also accessible by other GIS applications. Standard functionality includes crawling and indexing for projects, seismic files, boreholes, log data and surface picks.”

Reservoir:

“Well data, horizons, faults and 2D grids are exchanged seamlessly with support for auditing. Structural data such as horizons and faults are evaluated for spill point and seal in JewelSuite using its unique ‘snap & seal’ functionality.  The re-interpreted horizons and faults data can then be repopulated in the database, allowing geophysicists and geologists to both have the same version of the data available at all times.”
