Technical Standards

The SEG Technical Standards Committee serves as a forum for discussion of geophysical developments in which standards for acquisition and processing of geophysical data need to be identified or improved. When data problems of a sufficient magnitude to warrant action by SEG are identified, an appropriate subcommittee is appointed to develop a set of standards and make a recommendation to the Executive Committee concerning their adoption. The committee works in partnership with a wide range of industry organizations. Standards are provided below in PDF and Microsoft Word as a convenience to the geophysical industry. Questions or comments about the documents, or corrections needed to them, should be reported to the committee chairman.

Positioning Standards

In 2009, SEG transferred custodianship of positioning standards to the International Association of Oil and Gas Producers (OGP). These standards, some of which are under revision by OGP, are available through the OGP's Geomatics Committee Web site.

Data Recording 2002 SEG-Y rev 1 The SEG Y Data Exchange Format (rev 0) was published in 1975, and has achieved widespread usage. However, since 1975, the nature of seismic data acquisition, processing, and seismic hardware has changed significantly. SEG Y rev 1 addresses these changes and updates the format for modern usage.
