PROFILE
Erich Suter
Eirik S. Utstumo developed and maintained core data export and modeling features in the equinor/fmu-dataio repository, focusing on geoscience data interoperability and reliability. He implemented TSurf and triangulated surface support, standardized fault surface reporting, and enhanced schema validation to ensure data integrity. Using Python, Pydantic, and YAML, Eirik refactored data models, improved error handling, and introduced robust unit testing with Pytest. His work included dependency management, CI workflow improvements, and metadata versioning, which reduced runtime errors and improved maintainability. Eirik’s contributions addressed both backend architecture and business needs, resulting in a more stable and extensible data IO platform.

Jun 1, 2025June 2025: Delivered two major feature improvements and supporting tests in the equinor/fmu-dataio repository, with a focus on fault surface data reporting and data-structure robustness. Implemented standardization of fault-related content naming, expanded export metadata tests, and introduced a dedicated enum value to support fault_surface reporting. Also refactored tsurf AllowedKeywordValues to use dictionaries for axis_names, axis_units, and z_positives, tightening validation and improving documentation. Completed schema alignment and typing fixes to reduce runtime errors and improve maintainability.

Nov 1, 2024November 2024-11 Monthly Summary for equinor/fmu-dataio: Implemented stratigraphic name mapping for FaultRoomSurface export. The change uses the global configuration's stratigraphy to map juxtaposition positions to SMDA names and introduces a get_stratigraphic_name utility to ensure correct mapping with warnings when stratigraphic elements are missing. This ensures exported data reflects the stratigraphic naming defined in configuration, improving data consistency for downstream analytics and reporting.
