Worked on the equinor/subscript repository to enhance the Eclcompress tool by expanding its default compression set to include flow-related directory paths. This update streamlines the handling of flow data by reducing the need for manual configuration and ensuring broader compression coverage. The implementation involved modifying Python-based command line utilities and developing automated tests to verify the integration and correctness of the new compression paths. By focusing on both the core logic and comprehensive testing, the work improved the reliability of flow data compression and contributed to a more maintainable workflow, leveraging skills in Python, command line tools, and software testing.
