Troika International is proud to introduce dChecker, a simple yet detailed software package to ensure your SEG-D data conforms to the SEG's format specifications.


dChecker allows preventative measures 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.


When dealing with large SEG-D files, dChecker allows you to select specific traces in order to quickly scan for problematic issues. The software will compare 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.


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