PSICAT is a free, open source application for core lithologic description. It is available for macOS and Windows.

PSICAT has a number of key features that make it particularly useful for the drilling/coring scientific community:​

  • Built to fit the workflow of core description — section-by-section in the lab
  • FGDC standards-based controlled vocabularies and patterns for lithologies and features by default
  • Customizable if additional or modified lithologies/features/patterns are needed, for improved characterization of specific lithologies, or support for additional disciplines
  • Back-end database references descriptive comments and features to core depth, for consistent ingest to data systems and direct comparison with analytical data tied to core depth
  • Utilizes core metadata to automate assembly of complete stratigraphic columns from descriptions of individual sections of core
  • Exports PDFs of core descriptions
  • Exports descriptions in spreadsheet format, tied to section depth, for direct comparison with other core datasets, optimized searching, and import to databases
  • Exports spliced (composite) stratigraphic columns from multiple cored holes
  • Real-time and batch-process error checking, to ensure data quality

PSICAT was developed by and for the drilling/coring scientific community. Primary development by J.Reed for ANDRILL. Now supported by CSDCO/LacCore and used in every project at the Facility and increasingly by the scientific community in their home institutions.
