A simple yet detailed software package to ensure your SEG-D data conforms to the SEG's format specifications.

This software can be used as a preventative measure to ensure your SEG-D records are always validated correctly. With customizable options to display various levels of detailed technical parameters, dChecker is an optimal tool for a wide variety of users to guarantee your SEG-D data is SEG compliant. It also allows the selection of specific traces in order to quickly scan for problematic issues. The software compares fields between headers to ensure consistency within your SEG-D records, and produces technical descriptions for the user on the nature of each specific issue.

The software will efficiently report any field and/or data structure violations which are easily viewed within the main dChecker window. Information found during the validation process can be seen in detailed PDF reports.


The software efficiently validates and ensures that the SEGY data is SEG compliant. This gives user confidence that a SEGY dataset is delivered at full compliance and that all troublesome data is located early on in the ingestion process.

The software provides the capability to validate entire directories based off the SEG standards for SEGY rev0 and rev1 and also allows customisation of specific items withing EBCDIC headers which can be validated throughout the entire SEGY project.
