The SIRIUS OBDA subsurface pilot project is addressing these shortcomings and aim to significantly broaden the applicability of the approach for use in subsurface projects.
Highlights of 2021
• [subsurface part of] the Optique was focused on developing OBDA on a relational database at Equinor (Ontology- Based Data Access to Slegge, ISWC 2017), which is no more an active database. Further, that database contains proprietary data, and access to that is now restricted. This resulted in a significant setback for researchers
to continue further extermination on extending OBDA capabilities. In 2021 we established a large in-house relational database from the publicly available G&G datasets (mainly by processing the Volve dataset https:/data. equinor.com & NPD FactPages https:/factpages.npd.no). This database is now being utilized in various other
internal and external research projects where G&G data is being used for experimentation, e.g., DigiWell at USN is also using this database for research purposes.
• Adapt mapping and Ontology from Optique
• Integration & testing
• SIRUS OBDA Subsurface V1.0 was demonstrated at the SIRIUS General Assembly in November 2021
Plans for 2022
• Evaluation of the pilot with Geoscientists, PDMs & CDMs at partner companies
• Experimentation on using OTTR (https:/ottr.xyz) for building and maintaining Ontology and mappings.
• Experimentation on extending the data sources to NoSQL data
• Integration with OSDU & potentially with DISKOS • Design, Development, Deployment and Evaluation
– OBDA Subsurface Pilot V2.0
