SEG-D seismic data format
File type: Various data file
An sgd file extension identifies a file containing seismic acquisition data in the SEG-D format.
SEG-D is a seismic data exchange format used to store recorded seismic traces and related acquisition information.
Found 4 different file type records with the same sgd filename suffix.

The SEG-D format was developed under the Society of Exploration Geophysicists (SEG) for recording and exchanging seismic field data.
An sgd file can contain seismic trace samples, trace headers, recording parameters, and other information needed to interpret data collected during a seismic survey.
SEG-D files are used as input to specialist geophysical processing and interpretation workflows rather than as ordinary documents. This format is marked as obsolete and is no longer supported by its developer, so newer systems may require an import function or legacy-data support to read it.
Open an sgd file with specialist seismic acquisition or geophysical processing software that supports the SEG-D format. General-purpose applications cannot normally interpret the trace data. If the file does not open, contact the organization that created the survey data or use a current geophysical system with SEG-D import support.
A compatible geophysical processing system can typically import SEG-D data and export the traces to another seismic format supported by that system.
Conversion may depend on the SEG-D variant and on information stored in the file headers, so the original acquisition or processing software is usually the most reliable option.
